LOW KICKBACK SAW CHAIN helps significantly reduce kickback, or the intensity of
kickback, due to specially designed depth gauges and guard links.
CHAIN BRAKE is a safety feature designed to reduce the possibility of injury due to kickback
by stopping a moving saw chain in milliseconds. It is activated by the Chain Brake lever.
SPARK ARRESTER SCREEN retains carbon and other flammable particles over 0.023
inches (0.6 mm) in size from engine exhaust flow. Compliance with local, state and federal
laws and/or regulations governing the use of a spark arrester screen is the user’s
responsibility. See Safety Precautions for additional information.
ENGINE SWITCH immediately stops the engine when tripped. Engine switch must be pushed
to ON position to start or restart engine.
SAFETY TRIGGER prevents accidental acceleration of the engine. Throttle trigger cannot be
squeezed unless the safety latch is depressed.
CHAIN BRAKE LEVER / HAND GUARD protects the operator’s left hand in the event it slips
off the front handle while saw is running.
CHAIN CATCHER reduces the danger of injury in the event saw chain breaks or derails
during operation. The chain catcher is designed to intercept a whipping chain.
NOTE: Study your saw and be familiar with its parts.

5 SAFETY
▪ DO NOT operate a chain saw with one hand! Serious injury to the operator, helpers,
bystanders, or any combination of these persons may result from one-handed operation. A
chain saw is intended for two-handed use.
▪ DO NOT operate a chain saw when you are fatigued, under the influence of drugs, alcohol
or medication.
▪ Use safety footwear, snug-fitting clothing, protective gloves, and eye, hearing and head
protection devices.
▪ Use caution when handling fuel. To avoid fire, move the chain saw at least 10 feet (3 m)
from the fuelling point before starting the engine.
▪ DO NOT allow other persons to be near when starting or cutting with the chain saw. Keep
bystanders and animals out of the work area.
▪ DO NOT start cutting until you have a clear work area, secure footing, and a planned
retreat path from the falling tree.
▪ Keep all parts of your body away from the saw chain when the engine is running.
▪ Before you start the engine, make sure that the saw chain is not contacting anything.
▪ Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and
the muffler away from your body.
▪ DO NOT operate a chain saw that is damaged, improperly adjusted, or not completely and
securely assembled. Be sure that the saw chain stops moving when the throttle control
trigger is released.
▪ Shut off the engine before setting the chain saw down.
▪ Use extreme caution when cutting small size brush and saplings because slender material
may catch the saw chain and be whipped toward you or pull you off balance.
▪ When cutting a limb that is under tension, be alert for spring back so that you will not be
struck when the tension in the wood fibres is released.
▪ Keep the handles dry, clean, and free of oil or fuel mixture.
▪ Operate the chain saw only in well-ventilated areas.
▪ DO NOT operate a chain saw in a tree unless you have been specifically trained to do so.
▪ All chain saw service, other than the items listed in the user manual safety and
maintenance instructions, should be performed by competent chain saw service
personnel.
▪ During transport and storage of your chain saw, use the supplied guide bar cover.
▪ DO NOT operate your chain saw near or around flammable liquids or gases whether in or
out of doors. An explosion and/or fire may result.
▪ Do not fill fuel tank, oil tank or lubricate when the engine is running.
▪ USE THE RIGHT TOOL: Cut wood only. Do not use the chain saw for purposes for which
it was not intended. For example, do not use the chain saw for cutting plastic, masonry, or
non-building materials.
▪ The first time user should have practical instruction in the use of chainsaw and the
protective equipment from an experienced operator.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 6 www.varo.com
▪ Do not attempt to hold the saw with one hand only. You cannot control reactive forces
and you may lose control of the saw, which can result in the skating or bouncing of the bar
and chain along the limb or log.
▪ Never run the chainsaw indoors. Your chainsaw produces poisonous exhaust as soon as
the combustible engine is started, which may be colourless and odourless. To use this
product can generate dust, mists and fumes containing chemicals known to cause
reproductive harm. Be aware of harmful dust, mist (such as saw dust or oil mist from chain
lubrication) and protect yourself properly.
▪ Wear gloves and keep your hand warm. Prolonged use of chainsaws exposing the
operator to vibrations may produce whitefinger disease. In order to reduce the risk of
whitefinger disease, please wear gloves and keep your hand warm. If any of the
whitefinger symptoms appear, seek medical advice immediately.
▪ Drive in the spiked bumper of the chainsaw directly behind the intended hinge and pivot
the saw around this point. The spiked bumper rolls against the trunk.
▪ Only chain, guide bar and spark plug can be replaced by the user himself. Always make
sure you replace with correct material as stated in the specifications of the manual.
6 KICKBACK SAFETY PRECAUTIONS
KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when
wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar
up and back toward the operator.
PINCHING the saw chain along the BOTTOM of the guide bar may PULL the saw forward
away from the operator.
PINCHING the saw chain along the TOP of the guide bar may PUSH the guide bar rapidly
back toward the operator.
Any of these reactions may cause you to lose control of the saw, which could result in serious
personal injury.
▪ With a basic understanding of kickback, you can reduce or eliminate the element of
surprise. Sudden surprise contributes to accidents.
▪ Keep a good firm grip on the saw with both hands, the right hand on the rear handle, and
the left hand on the front handle, when the engine is running. Use a firm grip with thumbs
and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and
maintain control of the saw. Don’t let go.
▪ Make sure that the area in which you are cutting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch, or any other obstruction which could be hit
while you are operating the saw.
▪ Cut at high engine speeds.
▪ Do not overreach or cut above shoulder height.
▪ Follow manufacturer’s sharpening and maintenance instructions for the saw chain.
▪ Only use replacement bars and chains specified by the manufacturer or the equivalent.
NOTE: Low-kickback saw chain is chain that has met the kickback
performance.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 7 www.varo.com
WARNING: Kickback can lead to dangerous loss of control of the chain saw
and result in serious or fatal injury to the saw operator or to anyone
standing close by. Always be alert. Rotational kickback and pinch-kickback
are major chain saw operational dangers and the leading cause of most
accidents.
Beware of:
▪ Rotational kickback (Fig. 2a)
A = kickback path
B = kickback reaction zone
▪ The push (pinch kickback) and pull reactions a = pull (Fig. 2b)
B = solid objects
C = push
When the chain saw fails to dig in during a cut, the guide bar can begin hopping or
dangerously skidding along the surface of the log or branch, possibly resulting in the loss of
control of the chain saw. To prevent or reduce skating, hold the chain saw with two hands and
make sure the saw chain establishes a groove for cutting.
7 SAFETY WARNINGS GASOLINE
WARNING: Use extra care in handling fuels. They are flammable and the
vapours are explosive.
The following points must be observed:
▪ Use only an approved container.
▪ Never remove the fuel cap or add fuel with the power source running. Allow engine
exhaust components to cool before refuelling.
▪ Do not smoke.
▪ Never refuel the machine indoors.
▪ Never store the machine or fuel containers inside, where is an open flame, such as a
water heater.
▪ If fuel is spilled, do not attempt to start the power source, but move the machine away
from the area of spillage before starting.
▪ Always replace and securely tighten the fuel cap after refuelling.
▪ If the tank is drained, this should be done outdoors.
8 ASSEMBLY
8.1 Installing Guide Bar and Saw Chain

(Fig. 6)
POWEG2005 EN
Copyright © 2022 VARO P a g e | 8 www.varo.com
Note: Pay attention to the correct direction of the saw chain. (Fig. 7)
▪ Fit the bar retaining nut (14) into the lower hole of the guide bar (2), then install the chain
cover (22), and fasten the bar retaining nut to finger tightness. (Fig. 8)
▪ While holding up the tip of the bar, adjust the chain tension by turning the saw chain
adjustment screw (18) until the chain links just touch the bottom side of the bar rail. (Fig.
9)
▪ Tighten the nuts securely with the bar tip held up (11.8-14.7 N.m./120-150 kg-cm). Then
check the chain for smooth rotation and proper tension while moving it by hand. If
necessary, re-adjust with the chain cover (22) loose. (Fig. 10)
▪ Tighten the saw chain adjustment screw (18).
Warning: A new chain will expand its length in the beginning of
use.
Check and readjust the tension frequently as a loose
chain can easily derail
or cause rapid wear of itself and the guide bar.
9 FUEL AND LUBRICATION
9.1 Fuel
Use regular grade unleaded gasoline mixed with 40:1 custom 2-cycle engine oil for best
results. Use mixing ratios in section fuel mixing table below.
Warning: never use straight gasoline in your unit. This will cause permanent
engine damage and void the manufacturer’s warranty for that product.
Never use a fuel mixture that has been stored for over 90 days.
Warning: 2-cycle lubricant must be a premium grade oil for 2-cycle air
cooled engines mixed at a 40 : 1 ratio. Do not use any 2-cycle oil product
with a recommended mixing ratio of 100:1. If insufficient lubrication is the
cause of engine damage, it voids the manufacturer’s engine warranty.
9.2 Mixing fuel
Add oil to an approved fuel container followed by the gasoline to allow incoming gasoline to
mix with oil. Shake container to ensure thorough mix.
Warning: Lack of lubrication voids engine warranty. Gasoline and oil must
be mixed at 40:1

9.2.3 Recommended fuels
Some standard petrols are enriched with oxygen-containing compounds such as alcohol or
ether to comply with regulations on clean air. The motor is designed to work well on any car
petrol, including these enriched petrols, on the condition that the above mixing ratios are
observed!
9.2.4 Filling with fuel
▪ Clean the area around the cap of the fuel tank, and remove all wood dust and dirt.
▪ Open the fuel tank by turning the cap anticlockwise.
▪ Fill with fresh 2-stroke mix, DO NOT overfill.
▪ When finished refuelling, immediately refit the cap to the fuel tank, and close by turning it
clockwise until hand tight and sealed.
Warning: Move at least 3 m from the fuelling spot, away from potential
spillage and escaped fumes, before attempting to start the engine.
9.3 Chain oil
9.3.1 Chain and bar lubrication
Always refill the chain oil tank each time the fuel tank is refilled. We recommend using our
chain & bar oil (check our oil assortment). To ensure the bar and chain receive oil, only use
the original style bar with the oil passage hole (A) as illustrated above (Fig. 11). Always use
good quality sprocket oil, which contains additives to reduce friction and wear and to assist in
the prevention of pitch formation on the bar and chain.
9.3.2 Filling with chain oil
Warning: be careful not to spill any oil. Thoroughly clean away any spilled
chain oil, even if bio-degradable chain oil is used. Be aware of slipping
hazards!
40 : 1
POWEG2005 EN
Copyright © 2022 VARO P a g e | 10 www.varo.com
▪ Clean the area around the chain oil reservoir, and remove all wood dust and dirt.
▪ Open the chain oil reservoir cap by turning it anticlockwise.
▪ Fill with special chain oil. Do not overfill.
▪ Immediately refit the chain oil reservoir cap, and close by turning it clockwise until hand
tight and sealed.
9.4 How to mix fuel
Pay attention to agitation.
▪ Measure out the quantities of gasoline and oil to be mixed.
▪ Put some of the gasoline into a clean, approved fuel container.
▪ Pour in all of the oil and agitate well.
▪ Pour in the rest of gasoline and agitate again for at least one minute. As some oils may be
difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the
engine to last long. Be careful that, if the agitation is insufficient, there is an increased
danger of early piston seizing due to ab- normally lean mixture.
▪ Put a clear indication on the outside of the container to avoid mixing up with gasoline or
other containers.
▪ Indicate the contents on outside of container for easy identification.
9.5 Fueling the unit
▪ Untwist and remove the fuel cap. Rest the cap on a dustless place.
▪ Put fuel into the fuel tank to 80% of the full capacity.
▪ Fasten the fuel cap securely and wipe up any fuel spillage around the unit.
▪ Select bare ground for fueling.
▪ Move at least 10 feet (3 meters) away from the fueling point before starting the engine.
▪ Stop the engine before refueling the unit. At that time, be sure to sufficiently agitate the
mixed gasoline in the container.
9.6 For your engine life, avoid:
▪ FUEL WITH NO OIL (RAW GASOLINE) – It will cause severe damage to the internal
engine parts very quickly.
▪ GASOHOL – It can cause deterioration of rubber and/or plastic parts and disruption of
engine lubrication.
▪ OIL FOR 4-CYCLE ENGINE USE – It can cause spark plug fouling, exhaust port blocking,
or piston ring sticking.
▪ Mixed fuels which have been left unused for a period of one month or more may clog the
carbu- retor and result in the engine failing to operate prop- erly.
▪ In the case of storing the product for a long period of time, clean the fuel tank after
rendering it empty. Next, activate the engine and empty the carburetor of the composite
fuel.
▪ In the case of scrapping the used mixed oil con- tainer, scrap it only at an authorized
repository site.
10 OPERATION
Warning! It is very dangerous to run a chainsaw that mounts broken parts or
lacks any parts. Before starting engine, make sure that all the parts
including bar and chain are installed properly.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 11 www.varo.com
10.1 Starting the engine
10.1.1 Normal start
▪ Fill fuel and chain oil tanks respectively, and tighten the caps (11 – 10) securely. (Fig. 12)
▪ Continuously push the primer bulb (23) until fuel comes in the bulb. (Fig. 13)
▪ Set the switch (7) to “I” position. (Fig. 14)
▪ Pull out the choke lever (17). The choke will close and the throttle lever (20) will then be
set in the starting position. (Fig. 15)
Note: When restarting immediately after stopping the engine, set the Choke
lever (17) in the first-stage position (choke open and throttle lever in the
starting position).
▪ Once the choke lever has been pulled out, it will not return to the operating position even if
you press down on it with your finger. When you wish to return the choke lever to the
operating position, pull out the throttle lever (20) instead.
▪ While holding the saw unit securely on the ground, pull the starter handle (6) vigorously.
(Fig. 16)
Warning! Do not start the engine while the chain saw hangs in one hand.
The saw chain may touch your body. This in very dangerous.
▪ When engine has ignited, first push in the choke lever (17) to the first stage position and
then pull the starter (6) again to start the engine.
▪ Allow the engine to warm up with the throttle lever pulled slightly.
The starting performance of the engine depends on the adjustment of the
engine.
Be careful not to set OPS in motion except when starting the engine. If so, it
may lead to serious injury.
Warning! Be sure to perform warming-up with the guide bar and the saw
chain mounted.
Warning! Keep clear of the saw chain as it will start rotatIng upon starting of
engine.
Warning! Before you start the engine, make sure the saw chain is not
contacting anything.
10.2 Checking the oil supply
Warning! Make sure to set up the bar and the chain when checking the oil
supply. If not, the rotating parts may be exposed. It is very dangerous.
After starting the engine, run the chain at medium speed and see if chain oil is scattered off as
shown in the fig. 19
The chain oil flow can be changed by inserting a screwdriver in the hole on bottom of the
clutch side. Adjust according to your work conditions. (Fig. 20)
POWEG2005 EN
Copyright © 2022 VARO P a g e | 12 www.varo.com
The oil tank should become nearly empty by the time fuel is used up. Be sure to refill the
oil tank every time when refueling the saw.
10.3 Chain brake
The chain brake is a device which stops the chain instantaneously if the chain saw recoils
due to kickback. Normally, the brake is activated automatically by inertial force. It can also be
activated manually by pushing the brake lever (4) (left-hand guard) down toward the front.
10.3.1 Releasing the brake (Fig. 21)
Pull the brake lever (4) up toward the left-hand handle until it clicks into place.
Warning! When the brake operates, release the throttle lever (20) to slow
down the engine speed. Continuous operation with the brake engaged will
generate heat from the clutch and may cause trouble.
Warning! At machine inspection prior to each job, check the operating
condition of the brake following the steps.
▪ Start the engine and grasp the handle securely with both hands.
▪ Pulling the throttle lever (20) to maintain the chain operation, push the brake lever (4) (left-
hand guard) down toward the front using the back of your left hand.
▪ When the brake operates and the chain is stopped, release the throttle lever.
▪ Release the brake.
10.4 Stopping the engine
▪ Release the throttle lever (20) to allow the engine to idle for a few minutes.
▪ Set the switch (7) to the “O” (STOP) position. (Fig. 22)
10.5 General cutting instructions
10.5.1 Felling
Felling is the term for cutting down a tree. Small trees up to 6-7 inches (15-18 cm) in diameter
are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the
direction the tree will fall.
Felling a tree:
Warning: a retreat path (A) should be planned and cleared as necessary
before cuts are started. The retreat path should extend back and diagonally
to the rear of the expected line of fall, as illustrated in Fig. 23a.
Caution: if felling a tree on sloping ground, the chain saw operator should
keep on the uphill side of the terrain, as the tree is likely to roll or slide
downhill after it is felled.
Note: direction of fall (B) is controlled by the notching cut. Before any cuts
are made, consider the location of larger branches and natural lean of the
tree to determine the way the tree will fall.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 13 www.varo.com
Warning: do not cut down a tree during high or changing winds or if there is
a danger to property. Consult a tree professional. Do not cut down a tree if
there is a danger of striking utility wires; notify the utility company before
making any cuts.
General guidelines for felling trees: (Fig. 23b)
Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut
(D). Start making the upper notch cut (C) on the side of the tree facing the felling direction (E).
Be sure you don t make the lower cut too deep into the trunk.
The notch (C) should be deep enough to create a hinge (F) of sufficient width and strength.
The notch should be wide enough to direct the fall of the tree for as long as possible.
WARNING: Never walk in front of a tree that has been notched. Make the
felling cut (D) from the other side of the tree and 1.5 - 2.0 inches (3-5 cm)
above the edge of the notch (C) (Fig. 23b).
Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If
the trunk is completely cut through, control over the felling direction is lost.
Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to
move. This will prevent the guide bar from binding in the felling cut if you have misjudged the
falling direction. Make sure no bystanders have entered the range of the falling tree before you
push it over.
Warning: before making the final cut, always recheck the area for
bystanders, animals or obstacles.
Felling cut:.
▪ Use wooden or plastic wedges (A) to prevent binding the bar or chain (B) in the cut.
Wedges also control felling (Fig. 23c).
▪ When diameter of wood being cut is greater than the bar length, make 2 cuts as shown
(Fig. 23d).
WARNING: As the felling cut gets close to the hinge, the tree should begin
to fall. When tree begins to fall, remove saw from cut, stop engine, put chain
saw down, and leave area along retreat path (Fig. 23a).
10.5.2 Limbing
▪ Limbing a tree is the process of removing the branches from a fallen tree. Do not remove
supporting limbs until after the log is bucked (cut) into lengths (Fig. 24).
▪ Branches under tension should be cut from the bottom up to avoid binding the chain saw
WARNING: Never cut tree limbs while standing on tree trunk.
10.5.3 Bucking
Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill
of the log when cutting on sloping ground. If possible, the log should be supported so that the
end to be cut off is not resting on the ground. If the log is supported at both ends and you must
cut in the middle, make a downward cut halfway through the log and then make the undercut.
This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut
POWEG2005 EN
Copyright © 2022 VARO P a g e | 14 www.varo.com
into the ground when bucking as this causes rapid dulling of the chain. When bucking on a
slope, always stand on the uphill side.
▪ Log supported along entire length: Cut from top (overbuck), being careful to avoid cutting
into the ground (Fig. 25a).
▪ Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid
splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig.
25b).
▪ Log supported on both ends: First, overbuck 1/3 diameter of log to avoid splintering.
Second, underbuck to meet first cut and avoid pinching (Fig. 25c).
NOTE: The best way to hold a log while bucking is to use a sawhorse. When
this is not possible, the log should be raised and supported by the limb
stumps or by using supporting logs. Be sure the log being cut is securely
supported.
10.5.4 Bucking using a sawhorse
For personal safety and ease of cutting, the correct position for vertical bucking is essential
(Fig. 26).
Vertical cutting:
▪ Hold the saw firmly with both hands and keep the saw to the right of your body while
cutting.
▪ Keep the left arm as straight as possible.
▪ Keep weight on both feet.
Caution: while the saw is cutting, be sure the chain and bar are being
properly lubricated.
10.5.5 Spiked bumper (13)
The spiked bumper must always be put on, while using the chain saw on tree trunk. Push the
spiked bumper into the tree trunk by using the rear handle. Push the front handle in the
direction of cutting line. The spiked bumper must be remaining set for further saw guiding if
necessary. Use a spiked bumper when cutting trees and thick branches can ensure your
safety and decrease the working strength and vibration level.
If there’s barrier between the cutting material and chainsaw, turn off the machine. Wait until it
stops completely. Wear the safety glove and remove the barrier. If the chain must be removed,
please follow the instruction of relevant part like installation in manual. A trial run must be
conducted after the cleaning and newly installation. If vibration or mechanical noise is
discovered, please stop the use and contact your dealer.

11.6 Carburettor adjustment
The carburettor was pre-set at the factory for optimum performance.
If further adjustments are necessary, please take your unit to the nearest qualified service
technician.
12 MAINTENANCE
12.1 Guide bar maintenance
Frequent lubrication of the guide bar (railed bar which supports and carries the saw chain)
sprocket tip is required. Proper maintenance of the guide bar, as explained in this section, is
essential to keep your saw in good working condition.
▪ Dismount the Saw Chain (1) and Guide Bar (2) by following the instructions in ‘Assembling
the chainsaw’ in reverse
▪ Remove saw dust from the bar groove and oiling port using a small screwdriver, probe
(not included) (see Fig. 31), or compressed air
▪ Inspect the Guide Bar and the sprocket on its tip. Lubricate the sprocket with a suitable
maintenance spray
▪ Deburr, turn over or replace the Guide Bar as required.
12.2 Sprocket tip lubrication
Caution: the sprocket tip on your new saw has been pre-lubricated at the
factory. Failure to lubricate the guide bar sprocket tip as explained below
will result in poor performance and seizure, voiding the manufacturer’s
warranty.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 17 www.varo.com
Lubrication of the sprocket tip is recommended after 10 hours of use or once a week,
whichever occurs first. Always thoroughly clean guide bar sprocket tip before lubrication.
Tools for lubrication:
The lube gun (optional) is recommended for applying grease to the guide bar sprocket tip. The
lube gun is equipped with a needle nose tip which is necessary for the efficient application of
grease to the sprocket tip.
To lubricate sprocket tip:
Warning: wear heavy duty work gloves when handling the bar and chain.
▪ Press the stop switch down.
Note: it is not necessary to remove the saw chain to lubricate the guide bar
sprocket tip. Lubrication can be done on the job.
▪ Clean the guide bar sprocket tip.
▪ Using the lube gun (optional), insert needle nose into the lubrication hole and inject grease
until it appears at outside edge of sprocket tip (Fig. 32).
▪ Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has
been greased.
12.3 Guide bar maintenance
Most guide bar problems can be prevented merely by keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw with chain that is too tight will
contribute to rapid bar wear. To help minimize bar wear, the following guide bar maintenance
procedures are recommended.
Warning: always wear protective gloves during maintenance operations. Do
not carry out maintenance when the engine is hot.
12.4 Chain sharpening
Chain sharpening requires special tools to ensure that cutters are sharpened at the correct
angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be
professionally sharpened by the nearest professional service centre. For non-experienced
users of the chain saw, we recommend to have the chain sharpened by a specialist in any
authorized service.
Warning: when having wrong sharpened chain, there may occur a higher
danger of kickback.
▪ To sharpen the saw chain, use the suitable sharpening tools:
round chain file
file leading
chain measuring calibre.
These tools can be bought in any specialized stores.
▪ To gain well shaped sawdust particles, use sharp chain. If there appears wooden powder,
you must sharpen the saw chain.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 18 www.varo.com
Warning: all cutting teeth must be similarly long. Different length of the teeth
can cause rough run of the chain or its rupture, as well.
▪ Minimum length of the teeth must be 4 mm. If they are shorter, remove the saw chain.
▪ Angles, which the teeth are under, must be followed.
▪ To sharpen the chain basically, make 2 to 3 pulls of the file from the inside out.
Warning: after 3 to 4 of your sharpening of the cutting teeth, have the saw
chain sharpened in any authorised service. They will sharpen the depth
limiter as well, which provides the distance.
Chain sharpening
The pitch of the chain (Fig. 33) depends on the model.
POWEG2005
Pitch
3/8”
Gauge
0.050”
Sharpen the chain using protective gloves and a round file of ø5/32” (4 mm).
Always sharpen the cutters only with outward strokes (Fig. 34) observing the values given in.
After sharpening, the cutting links must all have the same width and length.
Warning: a sharp chain produces well-defined chips. When your chain starts
to produce sawdust, it is time to sharpen.
▪ After every 3-4 times the cutters have been sharpened you need to check the height of the
depth gauges and, if necessary, lower them using the flat file and template supplied
optional, then round off the front corner (Fig. 35).
WARNING: Proper adjustment of the depth gauge is as important as proper
sharpening of the chain.
12.5 Guide bar
The bar should be reversed every 8 working hours to ensure uniform wear. Keep the bar
groove and lubrication hole clean using a bar groove cleaner (optional) (Fig. 36)
Warning: never mount a new chain on a worn sprocket or self-aligning ring.
Bar wear - turn guide bar frequently at regular intervals (for example, after 8 hours of use), to
ensure even wear on top and bottom of bar.
Oil passages - oil passages on the bar should be cleaned to ensure proper lubrication of the
bar and chain during operation.
Note: the condition of the oil passages can be easily checked. If the
passages are clear, the chain will automatically give off a spray of oil within
seconds of starting the saw. Your saw is equipped with an automatic oiler
system.
POWEG2005 EN
Copyright © 2022 VARO P a g e | 19 www.varo.com
12.6 Chain maintenance
Chain tension:
Check the chain tension frequently and adjust as often as necessary to keep the chain snug
on the bar, but loose enough to be pulled around by hand.
Breaking in a new saw chain:
A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during
the break-in period, and the interval between future adjustments will begin to lengthen quickly.
Warning: never have more than 3 links removed from a loop of chain. This
could cause damage to the sprocket.
Chain lubrication:
Always make sure the automatic oiler system is working properly. Keep the oil tank filled with
good quality chain, bar and sprocket oil.
Adequate lubrication of the bar and chain during cutting operations is essential to minimize
friction with the guide bar.
Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will
decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to
excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar
discoloration.
Chain sharpening:
For the inexperienced chain saw user, we recommend that the saw chain be professionally
sharpened by the nearest professional service centre. If you feel comfortable sharpening your
own saw chain, special tools are available from the professional service centre.

15 STORING A CHAIN SAW
Caution: never store a chain saw for longer than 30 days without performing
the following procedures. Storing a chain saw for longer than 30 days
requires storage maintenance. Unless the storage instructions are followed,
fuel remaining in the carburettor will evaporate, leaving gum-like deposits.
This could lead to difficult starting and result in costly repairs.
▪ Remove the fuel tank cap slowly to release any pressure in tank. Carefully drain the fuel
tank.
▪ Start the engine and let it run until the unit stops to remove fuel from carburettor.
▪ Allow the engine to cool (approx. 5 minutes).
▪ Using a spark plug wrench, remove the spark plug.
▪ Pour 1 teaspoon of clean 2-cycle oil into the combustion chamber. Pull starter rope slowly
several times to coat internal components. Replace spark plug.
Note: store the unit in a dry place and away from possible sources of
ignition such as a furnace, gas hot water heater, gas dryer, etc.
Removing a unit from storage
▪ Remove spark plug.
▪ Pull starter rope briskly to clear excess oil from combustion chamber.
▪ Clean and gap spark plug or install a new spark plug with proper gap.
▪ Prepare unit for operation.
▪ Fill fuel tank with proper fuel / oil mixture. See fuel and lubrication section.
