bevel pawl, remove the retaining screw, the 22.5 ° bevel pawl and the 30 ° crown bevel pawl.
Flip the crown bevel pawl so the 33.9 °  is facing up. Reattach the screw to secure the 22.5 °
bevel pawl and the crown bevel pawl. The accuracy setting will not be affected.
22.5 ° Bevel Pawls (Fig. J)
Your saw is equipped to rapidly and accurately set a 22.5 ° bevel, left or right. The 22.5 ° bevel
pawl 47 can be rotated to contact the crown adjustment screw.
Rail Lock Knob (Fig. A)
The rail lock knob 30 allows you to lock the saw head firmly to keep it from sliding on the
rails. This is necessary when making certain cuts or when transporting the saw.
Depth Stop (Fig. A)
The depth stop 25 allows the depth of cut of the blade to be limited. The stop is useful for
applications such as grooving and tall vertical cuts. Rotate the depth stop forward and adjust
the depth adjustment screw 29 to set the desired depth of cut. To secure the adjustment,
tighten the wing nut 22 . Rotating the depth stop to the rear of the saw will bypass the depth
stop feature. If the depth adjustment screw is too tight to loosen by hand, the provided blade
wrench can be used to loosen the screw.
Slide Lock Transport Lever (Fig. L1–L3)
slide Lock Position (Fig. L1)

cutting capacity.
Transport Position (Fig. L2)
The slide lock transport lever 61 in rear location locks saw in the transport position to secure
the saw head during transport and storage. Recommended for relocating or carrying the saw.
stow Position (Fig. L3)
When not in use, the slide lock transport lever
lock lever locks in place using an indent on the back of the lever that slides up the ramp and
falls into the cast pocket 65 . To unlock the lever, slightly pull the lever till it clears out of the
cast pocket and rotate clockwise.
Automatic Electric Brake
Your saw is equipped with an automatic electric blade brake which stops the saw blade within
5 seconds of trigger release. This is not adjustable.
On occasion, there may be a delay after trigger release to brake engagement. On rare
occasions, the brake may not engage at all and the blade will coast to a stop.
If a delay or "skipping" occurs, turn the saw on and off 4 or 5 times. If the condition persists,
have the tool serviced by an authorized D
Always be sure the blade has stopped before removing it from the kerf. The brake
is not a substitute for guards or for ensuring your own safety by giving the saw your
complete attention.
Wireless Tool Control (Fig. A)

CAUTION: Read all saftey warnings, instruction and specifications of the appliance which
is paired with the tool.
Your tool is equipped with a Wireless Tool Control transmitter which allows your tool to be
wirelessly paired with another Wireless Tool Control device, such as a dust extractor.
To pair your tool using Wireless Tool Control, press and hold the trigger switch
and the Wireless Tool Control pairing button on the seperate device. An LED on the seperate
device will let you know when your tool has been successfully paired.

Prior to Operation

• Install the base extensions to both sides of the saw's base. Refer to Assembling the Base
Extensions section.
• Check the protective belt cover for damage and the proper functioning of the lower guard.
• Make sure to use the kerf plate. Do not operate the machine if the kerf slot is wider than
12 mm.
• 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.
• Make sure all locking knobs and clamp handles are tight.
• Use personal protective equipment and connect the saw to an external dust extractor.
• 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!
• Do not attempt to cut excessively small pieces.
• Secure the workpiece.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.

Body and Hand Position (Fig. M)

WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position
as shown.

WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation
of a sudden reaction.
Proper positioning of your body and hands when operating the mitre saw will make cutting
easier, more accurate and safer. 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 ARMS, AS SHOWN IN FIGURE M.
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.
Trigger Switch (Fig. N)
To turn the saw on, push the lock‑off lever
The saw will run while the switch is depressed. Allow the blade to spin up to full operating
speed before making the cut. To turn the saw off, release the switch. Allow the blade to stop
before raising the saw head. There is no provision for locking the switch on. A hole
provided in the trigger for insertion of a padlock to lock the switch off.
Always be sure the blade has stopped before removing it from the kerf.
Dust Extraction (Fig. O)

WARNING: To reduce the risk of serious personal injury, turn tool off, remove the
battery pack, and place lock lever in the transport position before transporting,
making any adjustments, cleaning, repairing, or removing/installing
attachments or accessories. An accidental start-up can cause injury.

CAUTION: Never operate this saw unless the dust bag or D
in place. Wood dust may create a breathing hazard.
Dust from materials such as lead‑containing coatings and some wood types, can be harmful
to one's health. Breathing‑in the dust can cause allergic reactions and/or lead to respiratory
infections of the user or bystanders. Certain dust, such as oak or beech dust, is considered
carcinogenic, especially in connection with wood treatment additives.
Observe the relevant regulations in your country for the materials to be worked. The vacuum
cleaner must be suitable for the material being worked.
When vacuuming dry dust that is especially detrimental to health or is carcinogenic, use a dust
on the tool
class M vacuum cleaner.
Your saw has a built‑in dust port
system to be connected.
To Attach the Dust Bag (Fig. P)
1. Fit the dust bag 53
To Empty the Dust Bag (Fig. P)
1. Remove dust bag
2. Reattach the dust bag back onto the dust port
You may notice that all the dust will not come free from the bag. This will not affect cutting
performance but will reduce the saw's dust collection efficiency. To restore your saw's dust
collection efficiency, depress the spring inside the dust bag when you are emptying it and tap
it on the side of the trash can or dust receptacle.
Through‑Cutting Operations (Fig. A)
If the slide feature is not used, ensure the saw head is pushed back as far as possible and
the rail lock knob is tightened. This will prevent the saw from sliding along its rails as the
workpiece is engaged.
nOTE: Although this saw will cut wood and many non‑ferrous materials, we will limit our
detailed discussion to the cutting of wood only. The same guidelines apply to the other
materials. DO NOT CUT FERROUS (IRON AND STEEL) MAT ERIALS OR MASONRY WITH THIS
SAW. Do not use any abrasive blades.
nOTE: Refer to Guard Actuation and Visibility in the Assembly and Adjustments section
for important information about the lower guard before cutting.
Crosscuts (Fig. A, Q)
A crosscut is made by cutting wood across the grain at any angle. A straight crosscut is made
with the mitre arm at the zero degree position. Set and lock the mitre arm at zero, hold the
wood firmly on the table and against the fence. With the rail lock knob tightened, turn on the
saw by squeezing the trigger switch
