Bevel Square to Table Adjustment (Fig. A, I, L)

1. To align the blade square to the table, lock the arm in the down position with the lock

down pin19.

2. Place a square against the blade, ensuring the square is not on top of a tooth (Fig. L).

3. Loosen the bevel lock knob28 and ensure the arm is firmly against the 0° bevelstop.

4. Rotate the 0° bevel adjustment screw (57 Fig. I) with the 13mm blade hex wrench27 as

necessary so that the blade is at 0° bevel to thetable.

Bevel Pointer Adjustment (Fig. I)

If the bevel pointers18 do not indicate zero, loosen each screw50 that holds each bevel

pointer in place and move them as necessary. Ensure the 0° bevel is correct and the bevel

pointers are set before adjusting any other bevel anglescrews.

Bevel Stop 45° Right and Left Adjustment (Fig. A, I)

To adjust the right 45° bevel stop:

1. Loosen the bevel lock knob28 and pull the bevel stop override knob30 to override the

0° bevelstop.

2. if the bevel pointer18 does not indicate exactly 45° when the saw is fully to the right and

the 45° bevel adjustment screw55 is contacting the 45° bevel override lever, turn the left

45° bevel adjustment screw55 with the 13 mm blade hex wrench27 (provided with

some units) until the bevel pointer indicates45°. Ensure the 45° bevel override lever52 is

in contact with the 45° bevel adjustment screw55.

To adjust the left 45° bevel stop:

1. Loosen the bevel lock knob28 and tilt the head to theleft.

2. If the bevel pointer18 does not indicate exactly 45°, turn the right 45° bevel adjustment

screw55 until the bevel pointer reads 45°.

Adjusting the Bevel Stop to 22.5° (or 30°) (Fig. A, I)

NOTE: Adjust the bevel angles only after performing the 0° bevel angle and bevel

pointeradjustment.

To set the left 22.5° bevel angle, flip out the left 22.5° bevel pawl53. Loosen the bevel lock

knob28 and tilt the head fully to the left. If the bevel pointer18 does not indicate exactly

22.5°, turn the crown adjustment screw51 contacting the pawl with a 10 mm wrench (not

provided) until the bevel pointer reads 22.5°.

To adjust the right 22.5° bevel angle, flip out the right 22.5° bevel pawl53. Loosen the bevel

lock knob28 and pull the bevel stop override knob30 to override the 0° bevel stop. When

the saw is fully to the right, if the bevel pointer does not indicate exactly 22.5°, turn the crown

adjustment screw51 contacting the pawl with a 10 mm wrench until the bevel pointer

indicates exactly 22.5°.

Fence Adjustment (Fig. A, Y2)

The upper part of the fence can be adjusted to provide clearance, allowing the saw to bevel to

a full 49° both left andright.

1. To adjust each fence16, loosen the fence adjustment knob63 and slide the fenceoutward.

2. Make a dry run with the saw turned off and check forclearance.

3. Adjust the fence to be as close to the blade as practical to provide maximum workpiece

support, without interfering with arm up and downmovement.

4. Tighten the fence adjustment knobsecurely.

5. When the bevel operations are complete, relocate thefence.

For certain cuts, it may be desirable to bring the fences closer to the blade. To do so, back the

fence adjustment knobs63 out two turns and move the fences closer to the blade past the

normal limit, then tighten the fence adjustment knobs. Make a dry cut first to ensure the blade

does not contact thefences.

NOTE: The tracks of the fences can become clogged with sawdust. Use a brush or some low

pressure air to clear the guidegrooves.

Guard Actuation and Visibility (Fig. A)

The lower guard1 on your saw has been designed to automatically uncover the blade when

the arm is brought down and to cover the blade when the arm israised.

The guard can be raised by hand when installing or removing saw blades or for inspection of

the saw. NEVER RAISE THE LOWER GUARD MANUALLY UN LESS THE BLADE ISSTOPPED.

Kerf Plate Adjustment (Fig. A)

To adjust the kerf plates11, loosen the 6 screws holding the kerf plates in place. Adjust so

that the kerf plates are as close as possible without interfering with the blade’smovement.

If a zero kerf width is desired, adjust the kerf plates as close to each other as possible. They can

now be cut slowly with the saw blade to give the smallest gap possible between the blade

and the kerfplates.

Rail Guide Adjustment (Fig. A)

Regularly check the rails23 for play or clearance. Ensure the rail lock knob24 isloosened.

The right rail can be adjusted with the rail adjustment screw25. To reduce clearance, use a

4 mm hex wrench (not provided) and rotate the set screw clockwise gradually while sliding

the saw head back andforth.

Mitre Lock Adjustment (Fig. A, M)

The mitre lock rod59 should be adjusted if the table of the saw can be moved when the

mitre lock handle is locked (down) and in a non-detentedposition.

1. Put the mitre lock handle8 in the unlocked (up)position.

2. Using a 13 mm open end wrench, loosen the lock nut58 on the mitre lockrod.

3. Using a slotted screwdriver, tighten the mitre lock rod by turning it clockwise as shown in

FigureM. Turn the lock rod until it is snug, then turn counterclockwise oneturn.

4. Re-lock the mitre lock to a non-detented measurement on the mitre scale – for example,

34° – and make sure the table will notrotate.

5. Tighten locknut.

Prior to Operation

• Install the appropriate saw blade. Do not use excessively worn blades. The maximum

rotation speed of the tool must not exceed that of the saw blade. Do not use any

abrasiveblades.

• Do not attempt to cut excessively smallpieces.

• Allow the blade to cut freely. Do notforce.

• Allow the motor to reach full speed beforecutting.

• Make sure all locking knobs and clamp handles aretight.

• Secure theworkpiece.

• Although this saw will cut wood and many nonferrous materials, these operating

instructions refer to the cutting of wood only. The same guidelines apply to the other

materials. Do not cut ferrous (iron and steel) materials, fibre cement or masonry with this saw!

• Make sure to use the kerf plate. Do not operate the machine if the kerf slot is wider than

10mm.

OPERATION

Instructions for Use

WARNING: Always observe the safety instructions and applicableregulations.

WARNING: To reduce the risk of serious personal injury, turn tool off and remove

the battery packs or power supply before transporting, making any adjustments,

cleaning, repairing, or removing/installing attachments or accessories. Be sure

the trigger switch is in the OFF position. An accidental start-up can causeinjury.

Refer to Saw Blades under Optional Accessories to select the blade that best fits yourneeds.

Ensure the machine is placed to satisfy your ergonomic conditions in terms of table height

and stability. The machine site shall be chosen so that the operator has a good overview and

enough free surrounding space around the machine that allows handling of the workpiece

without anyrestrictions.

To reduce effects of vibration make sure the environment temperature is not too cold, the

machine and accessories are well maintained and the workpiece size is suitable for thismachine.

The attention of UK users is drawn to the “woodworking machines regulations 1974” and any

subsequentamendments.

Proper Body and Hand Position (Fig. N1, N2)

WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand

position as shown in FigureN1.

WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in

anticipation of a suddenreaction.

• Never place hands near cutting area. Place hands no closer than 100 mm from theblade.

• Hold the workpiece tightly to the table and the fence when cutting. Keep hands in

position until the trigger has been released and the blade has completelystopped.

• ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT YOU CAN CHECK

THE PATH OF THE BLADE. DO NOT CROSS HANDS, AS SHOWN IN FIGUREN2.

• Keep both feet firmly on the floor and maintain proper balance. As you move the mitre

arm left and right, follow it and stand slightly to the side of the sawblade.

• Sight through the guard louvers when following a pencilline.

Switching On and Off (Fig. A)

To turn the saw on, depress the trigger switch5. To turn the tool off, release the triggerswitch.

Allow the blade to spin up to full operating speed before making thecut.

Release the trigger switch and allow the brake to stop the blade before raising the sawhead.

A hole is provided in the trigger switch for insertion of a padlock to lock the sawoff.

Use of XPS™ LED Worklight System (Fig. A)

NOTE: The mitre saw must be connected to a powersource.

The XPS™ LED Worklight System can be turned on by the momentary switch21. The light

will automatically turn off within 20 seconds if the saw is not in use. The light will activate

automatically every time the tool's main trigger5 ispulled.

To cut through an existing pencil line on a piece of wood:

1. Turn on the XPS™ system, then pull down on the operating handle3 to bring the saw

blade close to the wood. The shadow of the blade will appear on thewood.

2. Align the pencil line with the edge of the blade’s shadow. You may have to adjust the

mitre or bevel angles in order to match the pencil lineexactly.

Dust Extraction (Fig. A)

WARNING: To reduce the risk of serious personal injury, turn tool off and remove

the battery packs or power supply before transporting, making any adjustments,

cleaning, repairing, or removing/installing attachments or accessories. An

accidental start-up can causeinjury.

WARNING: Certain dust, such as oak or beech dust, is considered carcinogenic, especially

in connection with wood-treatmentadditives.

ʵ Always use dustextraction.

ʵ Provide for good ventilation of the workspace.

ʵ It is recommended to wear an appropriaterespirator.
