WARNING

Never modify this power tool in any way.

Only attachments supplied by STIHL or

expressly approved by STIHL for use

with the specific STIHL model are

authorized. Although certain

unauthorized attachments are useable

with STIHL power tools, their use may,

in fact, be extremely dangerous.

If this tool is subjected to unusually high

loads for which it was not designed (e. g.

heavy impact or a fall), always check

that it is in good condition before

continuing work. Check in particular that

the fuel system is tight (no leaks) and

that the controls and safety devices are

working properly. Do not continue

operating this machine if it is damaged.

In case of doubt, have it checked by your

STIHL servicing dealer.

THE USE OF THE POWER TOOL

Transporting the Power Tool

This power tool should be carried only in

a horizontal position. Grip the shaft in a

manner that the machine is balanced

horizontally. Keep the hot muffler away

from your body and the cutting

attachment behind you.

WARNING

Accidental acceleration of the engine

can cause the chain to rotate and cause

serious injuries.

Always switch off the engine and fit the

scabbard over the cutting attachment

before transporting the power tool over

long distances. When transporting it in a

vehicle, properly secure it to prevent

turnover, fuel spillage and damage to

the unit.

Fuel

Your STIHL power tool uses an oil-

gasoline mixture for fuel (see the

chapter on "Fuel" in this instruction

manual).

WARNING

Fueling Instructions

WARNING

To reduce the risk of serious burn injury,

never attempt to refuel the unit until it

has been completely removed from the

operator.

WARNING

Fuel your machine in well-ventilated

areas, outdoors. Always shut off the

engine and allow it to cool before

refueling. Gasoline vapor pressure may

build up inside the fuel tank depending

on the fuel used, the weather or other

environmental conditions and the use of

the machine.

In order to reduce the risk of burns and

other personal injury from escaping gas

vapor and fumes, remove the fuel filler

cap on your power tool carefully so as to

allow any pressure build-up in the tank

to release slowly. Never remove the fuel

filler cap while the engine is running.

Select bare ground for fueling and move

at least 10 feet (3 m) from the fueling

spot before starting the engine. Wipe off

any spilled fuel before starting your

machine.

390BA000 KN

Gasoline is an extremely

flammable fuel. If spilled

and ignited by a spark or

other ignition source, it

can cause fire and seri-

ous burn injury or

property damage. Use

extreme caution when

handling gasoline or fuel

mix. Do not smoke or

bring any fire or flame

near the fuel or the power

tool. Note that combus-

tible fuel vapor may

escape from the fuel sys-

tem or gas can during

fueling operations.

English

WARNING

To reduce the risk of fuel spillage and

fire from an improperly installed fuel cap,

correctly position and tighten the fuel

cap in the fuel tank opening.

WARNING

See also the "Fueling" chapter in this

instruction manual for additional

information.

Before Starting

Take off the chain guard (scabbard) and

inspect the pole pruner for proper

condition and operation. (See the

maintenance chart in this instruction

manual.)

WARNING

Always check your power tool for proper

condition and operation before starting,

particularly the throttle trigger, throttle

trigger lockout, stop switch and cutting

attachment. The throttle trigger must

move freely and always spring back to

the idle position. Never attempt to

modify the controls or safety devices.

WARNING

Check fuel system for leaks, especially

the visible parts, e.g., filler cap, hose

connections, manual fuel pump (only for

power tools equipped with a manual fuel

pump). To reduce the risk of personal

injury or property damage from fire, do

not start the engine if there are leaks or

damage. Have the machine repaired by

a servicing dealer before using it.

WARNING

Never operate your power tool if it is

damaged, improperly adjusted or

maintained, or not completely or

securely assembled.

WARNING

Check that the spark plug boot is

securely mounted on the spark plug – a

loose boot may cause arcing that could

ignite combustible fumes and cause a

fire.

Keep the handles clean and dry at all

times; it is particularly important to keep

them free of moisture, pitch, oil, fuel mix,

grease or resin in order for you to

maintain a firm grip and properly control

your power tool.

For proper assembly of the bar and

chain follow the procedure described in

the chapter "Mounting the Bar and

Chain" of your instruction manual.

STIHL Oilomatic chain, guide bar and

sprocket must match each other in

gauge and pitch.

WARNING

Proper chain tension is extremely

important. In order to avoid improper

setting, the tensioning procedure must

be followed as described in your

manual. Always make sure the hex

nut(s) for the sprocket cover is (are)

tightened securely after tensioning the

chain. Check chain tension once more

after having tightened the nut(s). Never

start the pole pruner with the sprocket

cover loose.

Adjust carrying harness and hand grip to

suit your size before starting work.

Starting

To reduce the risk of serious personal

injury from fire, start the engine at least

10 feet (3 m) from the fueling spot,

outdoors only.

Start and operate your pole pruner

without assistance.

Your power tool is a one-person

machine. Do not allow other persons in

the general work area, even when

starting.

For specific starting instructions, see the

appropriate section of your manual.

Check for fuel leakage

while refueling and during

operation. If fuel leakage

is found, do not start or

run the machine until the

leak is fixed and any

leaked fuel has been

wiped away. Take care

not to get fuel on your

clothing. If this happens,

change your clothing

immediately.

Unit vibrations can cause

an improperly installed

fuel filler cap to loosen or

come off and spill quanti-

ties of fuel. In order to

reduce the risk of fuel

spillage and fire, tighten

the fuel filler cap by hand

as securely as possible.

HT 102, HT 103, HT 132, HT 133

English

Place the pole pruner on firm ground or

other solid surface in an open area or, in

the alternative, as shown in the above

picture. Maintain good balance and

secure footing.

WARNING

To reduce the risk of injury from loss of

control, do not attempt to "drop start"

your power tool. Drop starting means

pushing the machine away from the

operator, or allowing it to drop toward

the ground, while pulling on the starter

grip. This method is very dangerous

because you may lose control of the

machine.

WARNING

To reduce the risk of injury from loss of

control be absolutely sure that the guide

bar and chain are clear of you and all

other obstructions and objects, including

the ground, because when the engine

starts at starting-throttle, engine speed

will be fast enough for the clutch to

engage the sprocket and turn the chain.

Once the engine has started,

immediately blip the throttle trigger,

which should release the starting throttle

and allow the engine to slow down to

idle.

With the engine running only at idle,

attach the power tool to the spring hook

of your harness (see appropriate

chapter of this manual).

WARNING

When you pull the starter grip, do not

wrap the starter rope around your hand.

Do not let the grip snap back, but guide

the starter rope to permit the rope to

rewind properly. Failure to follow this

procedure may result in injury to your

hand or fingers and may damage the

starter mechanism.

Important Adjustments

WARNING

To reduce the risk of personal injury

from loss of control or contact with the

running cutting tool, do not use your unit

with incorrect idle adjustment. At correct

idle speed, the saw chain should not

move. For directions on how to adjust

idle speed, see the appropriate section

of your instruction manual.

If you cannot set the correct idle speed,

have your STIHL dealer check your

power tool and make proper

adjustments and repairs.

Proper chain tension is very important at

all times. Check it at regular intervals

(during work breaks and only when the

pole pruner is shut off). If the chain

becomes loose while cutting, switch off

the engine and then tighten. Never try to

tighten the chain while the engine is

running.

During Operation

Holding and Controlling the Power Tool

Always hold the unit firmly with both

hands on the handles while you are

working. Wrap your fingers and thumbs

around the handles.

Place your left hand on the shaft and

your right hand on rear grip and throttle

trigger. Left-handers must follow these

instructions, too. Keep your hands in this

position to help maintain control of your

pole pruner while working at all times.

WARNING

Never attempt to operate your power

tool with one hand. Loss of control of the

power tool resulting in serious or fatal

injury may result.

WARNING

In order to properly control your pole

pruner, always maintain good balance

and a firm foothold. Never work on a

ladder, in a tree or on any other insecure

support. Never hold the machine above

shoulder height. Do not overreach.

When working at a height above 15 feet

(4.5 m) use a lift bucket. For pole pruner

with adjustable shaft, expand the shaft

only as far as necessary for the intended

application.

WARNING

Special care must be taken in slippery

conditions (wet ground, snow) and in

difficult, overgrown terrain. Watch for

hidden obstacles such as tree stumps,

roots, rocks, holes and ditches to avoid

stumbling. For better footing, clear away

fallen branches, scrub and cuttings. Be

extremely cautious when working on

slopes or uneven ground.

WARNING

Take extreme care in wet and freezing

weather (rain, snow, ice). Put off the

work when the weather is windy, stormy

or rainfall is heavy.

Working Conditions

Operate and start your power tool only

outdoors in a well-ventilated area.

Operate it under good visibility and

daylight conditions only. Work carefully.

WARNING

Inhalation of certain dusts, especially

organic dusts such as mold or pollen,

can cause susceptible persons to have

an allergic or asthmatic reaction.

Substantial or repeated inhalation of

dust and other airborne contaminants, in

particular those with a smaller particle

size, may cause respiratory or other

illnesses. This includes wood dust,

especially from hardwoods, but also

from some softwoods such as Western

Red Cedar. Control dust at the source

where possible. Use good work

practices, such as always cutting with a

properly sharpened chain (which

produces wood chips rather than fine

dust) and operating the unit so that the

wind or operating process directs any

dust raised by the power tool away from

the operator. Follow the

recommendations of EPA / OSHA /

NIOSH and occupational and trade

associations with respect to dust

("particulate matter"). When the

inhalation of dust cannot be

substantially controlled, i.e., kept at or

near the ambient (background) level, the

operator and any bystanders should

wear a respirator approved by NIOSH /

MSHA for the type of dust encountered.

WARNING

Breathing asbestos dust is dangerous

and can cause severe or fatal injury,

respiratory illness or cancer. The use

and disposal of asbestos-containing

products have been strictly regulated by

OSHA and the Environmental Protection

Agency. If you have any reason to

believe that you might be cutting

asbestos, immediately contact your

employer or a local OSHA

representative.

As soon as the engine is

running, this machine

generates toxic exhaust

fumes containing chemi-

cals, such as unburned

hydrocarbons (including

benzene) and carbon

monoxide, that are

known to cause respira-

tory problems, cancer,

birth defects, or other

reproductive harm and

other injuries. Some of

the gases (e. g. carbon

monoxide) may be color-

less and odorless and

can cause asphyxiation

or death very quickly. To

reduce the risk of serious

or fatal injury/illness from

inhaling toxic fumes,

never run the machine

indoors or in poorly venti-

lated locations. If exhaust

fumes become concen-

trated due to insufficient

ventilation, clear obstruc-

tions from work area to

permit proper ventilation

before proceeding and /

or take frequent breaks to

allow fumes to dissipate

before they become

concentrated.

HT 102, HT 103, HT 132, HT 133

English

WARNING

In order to reduce the risk of personal or

even fatal injury to bystanders from

falling objects or inadvertent contact with

the moving chain of your power tool

always keep bystanders at least 50 feet

(15 m) away when the power tool is

running.

WARNING

Even though bystanders should be kept

away from the running saw, never work

alone. Keep within calling distance of

others in case help is needed.

Stop the engine immediately if you are

approached.

DANGER

Electricity can jump from one point to

another by means of arcing. Higher

voltage increases the distance electricity

can arc. Electricity can also move

through branches, especially if they are

wet. Maintain a clearance of at least

50 feet (15 m) between the pole pruner

(including any branches it is contacting)

and any electrical line carrying live

current. Before working with less

clearance, contact your electric utility

and make sure the current is turned off.

Operating Instructions

WARNING

Do not operate your power tool using the

starting throttle position, as you do not

have control of the engine speed.

In the event of an emergency, switch off

the engine immediately by pressing the

stop switch.

WARNING

To reduce the risk of cut injuries, keep

hands and feet away from the saw

chain. Never touch a moving chain with

your hand or any other part of your body.

The saw chain continues to move for a

short period after the throttle trigger is

released (inertia effect).

Accelerating the engine while the chain

is blocked increases the load and will

cause the clutch to slip continuously.

This may result in overheating and

damage to important components (e. g.

clutch, polymer housing components) –

which can then increase the risk of injury

from the chain moving while the engine

is idling.

WARNING

If the chain becomes clogged, always

turn off the engine and make sure the

chain has stopped before cleaning.

Make sure that the saw chain does not

touch any foreign materials such as

rocks, fences, nails and the like. Such

objects may be flung off and injure the

operator or bystanders, or damage the

saw chain.

WARNING

Prior to limbing, clear the working area

from interfering limbs and brush. Then,

establish an escape area away from

where the cut limbs can fall, and remove

all obstacles.

Keep work area clear – move away

fallen limbs. Place all tools and

equipment at a safe distance from the

branches being limbed, but not in the

escape area.

WARNING

Always observe the general condition of

the tree. Look for decay and rot in the

trunk and branches. If it is rotted inside,

15m (50ft)

Your power tool is not

insulated against electric

shock. To reduce the risk

of electrocution, never

operate this power tool in

the vicinity of any wires or

cables (power, etc.)

which may be carrying

electric current.

HT 102, HT 103, HT 132, HT 133

English

it could snap and fall toward the operator

while being cut. Also look for broken or

dead branches which could vibrate

loose and fall on the operator. If branch

is thick or heavy, make a shallow relief

cut on the bottom of the branch before

cutting down from the top to help prevent

splitting of the branch. See chapter on

"Using the Unit".

WARNING

To reduce the risk of severe or even fatal

injury from falling objects do not cut

vertically above your body. Hold the pole

pruner at an angle of not more than 60°

from the horizontal level (see picture).

Objects may fall in unexpected

directions. Do not stand directly

underneath the limb being cut!

Watch for falling wood! As soon as the

limbed branch starts to fall, step aside

and keep a sufficient distance away from

the falling wood.

WARNING

Always pull the unit out of the cut with

the chain running to reduce the

possibility of pinching the cutting

attachment. Don't put pressure on the

pole pruner when reaching the end of a

cut. The pressure may cause the bar

and rotating chain to pop out of the cut or

kerf, go out of control and strike some

other object.

If the bar becomes pinched and caught

in the branch so that the chain can no

longer move, shut off the pole pruner

and carefully move the branch to open

the pinch and release the bar.

WARNING

If a rotating saw chain strikes a rock or

other hard object, sparks may be

created, which can ignite flammable

materials under certain circumstances.

Flammable materials can include dry

vegetation and brush, particularly when

weather conditions are hot and dry.

When there is a risk of fire or wildfire, do

not use a power tool around flammable

materials or around dry vegetation or

brush. Contact your local fire authorities

or the U.S. Forest Service if you have

any question about whether vegetation

and weather conditions are suitable for

the use of a pole pruner.

WARNING

Never modify your muffler. Any

modification could cause an increase in

heat radiation, sparks or sound level,

thereby increasing the risk of fire, burn

injury or hearing loss. You may also

permanently damage the engine. STIHL

recommends having your muffler

serviced and repaired by a STIHL

servicing dealer.

WARNING

The muffler and other parts of the engine

(e.g. fins of the cylinder, spark plug)

become hot during operation and remain

hot for a while after stopping the engine.

To reduce risk of burns, do not touch the

muffler and other parts while they are

hot. Keep the area around the muffler

clean. Remove excess lubricant and all

debris such as pine needles, branches

or leaves. Let the engine cool down

sitting on concrete, metal, bare ground

or solid wood (e.g. the trunk of a felled

tree) away from any combustible

substances.

WARNING

An improperly mounted or damaged

cylinder housing or a

damaged/deformed muffler shell may

interfere with the cooling process of the

muffler. To reduce the risk of fire or burn

injury, do not continue work with a

damaged or improperly mounted

cylinder housing or a

damaged/deformed muffler shell.

Your muffler is furnished with a spark

arresting screen designed to reduce the

risk of fire from the emission of hot

particles. Never operate your unit with a

missing or damaged spark arresting

screen. If your gas/oil mix ratio is correct

(i.e., not too rich), this screen will

normally stay clean as a result of the

heat from the muffler and need no

service or maintenance. If you

experience loss of performance and you

suspect a clogged screen, have your

246BA030 KN

HT 102, HT 103, HT 132, HT 133

English

muffler maintained by a STIHL servicing

dealer. Some state or federal laws or

regulations may require a properly

maintained spark arrestor for certain

uses. See the "Maintenance, Repair and

Storing" section of these Safety

Precautions. Remember that the risk of

a brush or forest fire is greater in hot or

dry conditions.

Reactive Forces

WARNING

Reactive forces may occur any time the

chain is rotating.The force used to cut

wood can be reversed and work against

the operator. If the rotating chain is

suddenly stopped by contact with any

solid object such as a branch or is

pinched, the reactive forces may occur

instantly. These reactive forces may

result in loss of control, which, in turn,

may cause personal injury. An

understanding of the causes of these

reactive forces may help you avoid the

element of surprise and loss of control.

Because of the design of the pole

pruner, the reactive forces experienced

when working with it are generally not as

severe as those encountered with a

chainsaw. Nevertheless, you should

always maintain a proper grip and good

footing to control the power tool when

you experience such forces.

The most common reactive forces are:

– kickback,

– pushback,

– pull-in.

Kickback

Kickback may occur when the moving

saw chain near the upper quadrant of

the bar nose contacts a solid object or is

pinched.

The reaction of the cutting force of the

chain causes a rotational force on the

pole pruner in the direction opposite to

the chain movement. This may cause

the bar to move upward.

To Avoid Kickback

The best protection from kickback is to

avoid kickback situations:

1. Be aware of the location of the guide

bar nose at all times.

2. Never let the nose of the guide bar

contact any object. Do not cut limbs

with the nose of the guide bar. Be

especially careful near wire fences

and when cutting small, tough

limbs, which may easily catch the

chain.

3. Cut only one limb at a time.

A = Pull-in

Pull-in occurs when the chain on the

bottom of the bar is suddenly stopped

when it is pinched, caught or encounters

a foreign object in the wood. The

reaction of the chain pulls the pole

pruner forward.

Pull-in frequently occurs when the chain

is not rotating at full speed before it

contacts the wood.

To Avoid Pull-in

1. Be alert to forces or situations that

may cause material to pinch the

chain at the bottom of the bar.

2. Always start a cut with the chain

rotating at full speed.

B = Pushback

Pushback occurs when the chain on the

top of the bar is suddenly stopped when

it is pinched, caught or encounters a

foreign object in the wood. The reaction

of the chain may drive the pole pruner

rapidly straight back toward the

A cutting attachment consists of the saw

chain, guide bar and chain sprocket.

The cutting attachment that comes

standard is designed to exactly match

the pole pruner.

– The pitch (t) of the saw chain (1),

chain sprocket and the nose

sprocket of the Rollomatic guide bar

must match.

– The drive link gauge (2) of the saw

chain (1) must match the groove

width of the guide bar (3).

If non-matching components are used,

the cutting attachment may be damaged

beyond repair after a short period of

operation.

Chain scabbard

Your pole pruner comes standard with a

chain scabbard that matches the cutting

attachment.

If you use guide bars of different lenghts

on the pole pruner, the length of the

chain scabbard must be matched to the

guide bar to reduce the risk of injury. It

should cover the full length of the guide

bar.

The length of the matching guide bars is

marked on the side of the chain

scabbard.

English

This engine is certified to operate on

unleaded gasoline and the STIHL two-

stroke engine oil at a mix ratio of 50:1.

Your engine requires a mixture of high-

quality gasoline and two-stroke air

cooled engine oil.

Use mid-grade unleaded gasoline with a

minimum octane rating of 89 ((R+M)/2)

and no more than 10% ethanol content.

Fuel with an octane rating below 89 may

increase engine temperatures. This, in

turn, increases the risk of piston seizure

and damage to the engine.

The chemical composition of the fuel is

also important. Some fuel additives not

only detrimentally affect elastomers

(carburetor diaphragms, oil seals, fuel

lines, etc.), but magnesium castings and

catalytic converters as well. This could

cause running problems or damage the

engine. For this reason STIHL

recommends that you use only quality

unleaded gasoline!

Gasoline with an ethanol content of

more than 10% can cause running

problems and major damage in engines

and should not be used.

For further details, see

www.STIHLusa.com/ethanol

The ethanol content in gasoline affects

engine speed – it may be necessary to

readjust the carburetor if you use fuels

with various ethanol contents.

WARNING

To reduce the risk of personal injury

from loss of control and / or contact with

the running cutting tool, do not use your

unit with incorrect idle adjustment. At

correct idle speed, the cutting tool

should not move.

If your power tool´s idle speed is

incorrectly adjusted, have your

authorized STIHL servicing dealer

check your machine and make the

proper adjustments and repairs.

The idle speed and maximum speed of

the engine change if you switch from a

fuel with a certain ethanol content to

another fuel with a much higher or lower

ethanol content.

This problem can be avoided by always

using fuel with the same ethanol

content.

To ensure the maximum performance of

your STIHL engine, use a high quality 2-

cycle engine oil, such as STIHL 2-cycle

engine oils. STIHL 2-cycle engine oils

are specially designed for STIHL

engines. To help your engine run

cleaner and reduce harmful carbon

deposits, STIHL recommends using

STIHL HP Ultra 2-cycle engine oil, or

use an equivalent high quality 2-cycle

engine oil.

To meet the requirements of EPA and

CARB we recommend to use STIHL HP

Ultra oil or equivalent.

Do not use BIA or TCW rated (two-

stroke water cooled) mix oils or other

mix oils that state they are for use in both

water cooled and air cooled engines

(e.g., outboard motors, snowmobiles,

chain saws, mopeds, etc.).

Take care when handling gasoline.

Avoid direct contact with the skin and

avoid inhaling fuel vapor. When filling at

the pump, first remove the container

from your vehicle and place the

container on the ground before filling. To

reduce the risk of sparks from static

discharge and resulting fire and/or

explosion, do not fill fuel containers that

are sitting in or on a vehicle or trailer.

The container should be kept tightly

closed in order to limit the amount of

moisture that gets into the mixture.

The machine’s fuel tank should be

cleaned as necessary.

STIHL MotoMix

STIHL recommends the use of STIHL

MotoMix. STIHL MotoMix has a high

octane rating and ensures that you

always use the right gasoline/oil mix

ratio.

STIHL MotoMix uses STIHL HP Ultra

two-stroke engine oil suited for high

performance engines.

For further details, see

www.STIHLusa.com/ethanol

Fuel mix ages

If not using STIHL MotoMix, only mix

sufficient fuel for a few days of work, not

to exceed 30 days of storage. Store in

approved fuel-containers only. When

mixing, pour oil into the container first,

and then add gasoline. Close the

container and shake it vigorously by

hand to ensure proper mix of oil and

gasoline.

For automatic and reliable lubrication of

the chain and guide bar – use only an

environmentally compatible quality

chain and bar lubricant. Rapidly

biodegradable STIHL BioPlus is

recommended.

NOTICE

Biological chain oil must be resistant to

aging (e.g. STIHL BioPlus), since it will

otherwise quickly turn to resin. This

results in hard deposits that are difficult

to remove, especially in the area of the

chain drive and chain. It may even cause

the oil pump to seize.

The service life of the chain and guide

bar depends on the quality of the

lubricant. It is therefore essential to use

only a specially formulated chain

lubricant.

WARNING

Do not use waste oil. Renewed contact

with waste oil can cause skin cancer.

Moreover, waste oil is environmentally

harmful.

NOTICE

Waste oil does not have the necessary

lubricating properties and is unsuitable

for chain lubrication.

NOTICE

A full chain oil tank is sufficient for only

half a tankful of fuel. Check the oil level

regularly during cutting work. Never

allow the oil tank to run dry.

Preparations

N Thoroughly clean the tank cap and

the area around it to ensure that no

dirt falls into the tank.

N Position the machine so that the

tank cap faces up.

Opening

N Raise the grip until it is upright.

N Turn the cap counterclockwise

(about a quarter turn).

Cutting effortlessly with a correctly

sharpened chain

A properly sharpened chain slices

through wood effortlessly and requires

very little feed pressure.

Do not work with a dull or damaged

chain as it will increase the physical

effort required, produce unsatisfactory

results and a higher rate of wear.

N Clean the chain.

N Check the chain for cracks in the

links and damaged rivets.

N Replace any damaged or worn

parts of the chain and match the

new parts to the shape and size of

the original parts.

Carbide-tipped saw chains (Duro) are

particularly wear resistant. STIHL

recommends you have your chain

resharpened by a STIHL servicing

dealer.

WARNING

It is absolutely essential to comply with

the angles and dimensions specified

below. If the saw chain is incorrectly

sharpened – and in particular if the depth

gauge is set too low – there is an

increased risk of kickback, with resulting

risk of injury.

The saw chain cannot be locked in place

on the guide bar. Therefore, it is best to

remove the chain from the bar and

resharpen it on a workshop sharpening

tool (FG 2, HOS, USG).

Chain pitch

The chain pitch (a) is marked on the

depth gauge end of each cutter.

Select file diameter according to chain

pitch – see table “Sharpening Tools”.

You must observe certain angles when

resharpening the chain cutter.

Filing and side plate angles

A Filing angle

STIHL saw chains are sharpened to a

filing angle of 30°. Exceptions are

ripping chains with a filing angle of 10°.

Ripping chains have an X in their

designations.

B Side plate angle

The correct side plate angle is obtained

automatically if you use the prescribed

file holder and file diameter.

The angles must be the same on all

cutters. If the angles are uneven: Chain

will run roughly, not in a straight line,

wear quickly and finally break.

File holder

N Use a file holder

A file holder must be used for manual

resharpening (see table "Sharpening

Tools"). The correct filing angles are

marked on the file holder.

During Break-In Period

A factory-new machine should not be

run at high revs (full throttle off load) for

the first three tank fillings. This avoids

unnecessary high loads during the

break-in period. As all moving parts

have to bed in during the break-in

period, the frictional resistances in the

engine are greater during this period.

The engine develops its maximum

power after about 5 to 15 tank fillings.

During Operation

NOTICE

Do not make the mixture leaner to

achieve an apparent increase in power –

this could damage the engine – see

"Adjusting the Carburetor".

Check chain tension frequently

A new chain has to be retensioned more

often than one that has been in use for

some time.

Chain cold

Tension is correct when the chain fits

snugly against the underside of the bar

and can still be pulled along the bar by

hand. Retension if necessary – see

"Tensioning the Saw Chain".

Chain at operating temperature

The chain stretches and begins to sag.

The drive links must not come out of the

bar groove – the chain may otherwise

jump off the bar. Retension the chain –

see "Tensioning the Saw Chain".

After long period of full-throttle operation

Allow engine to run for a short while at

idle speed so that engine heat can be

dissipated by the flow of cooling air. This

protects engine-mounted components

(ignition, carburetor) from thermal

overload.

After Finishing Work

N Slacken off the chain if you have

retensioned it at operating

temperature during cutting work.

NOTICE

Always slacken off the chain after

finishing work. The chain contracts as it

cools down. If it is not slackened off, it

can damage the gear shaft and

bearings.

Storing your saw for a short period

Wait for the engine to cool down. Drain

the fuel tank. Store the machine in a dry

location. Check the tightness of all

accessible screws and nuts (not

adjusting screws) at regular intervals

and retighten if necessary.

Storing for a long period

See chapter on "Storing the Machine"

N Turn the bar over every time you

sharpen the chain and every time

you replace the chain – this helps

avoid one-sided wear, especially at

the nose and underside of the bar.

N Regularly clean the oil inlet hole (1),

the oilway (2) and the bar

groove (3).

N Measure the groove depth – with the

scale on the filing gauge (special

accessory) – in the area used most

for cutting.

If groove depth is less than specified:

N Replace the guide bar.

Checking the Spark Plug

N Clean dirty spark plug.

N Check electrode gap (A) and

readjust if necessary – see chapter

"Specifications."

N Use only resistor type spark plugs of

the approved range.

Rectify problems which have caused

fouling of spark plug:

– too much oil in fuel mix,

– dirty air filter,

– unfavorable running conditions, e.g.

operating at part load.

WARNING

To reduce the risk of fire and burn injury,

use only spark plugs authorized by

STIHL. Always press the spark plug

boot (1) snugly onto the spark plug

terminal (2).

Do not use a spark plug with a

detachable SAE adapter terminal (3).

Arcing may occur that could ignite

combustible fumes and cause a fire.

This can result in serious injuries or

damage to property.

N Only use resistor type spark plugs

with solid, non-threaded terminals

Installing the Spark Plug

N Screw the spark plug (3) into the

cylinder.

N Tighten down the spark plug (3) with
