not assume that the printing on the blade will always be
facing you when properly installed. When retracting the
lower blade guard to install the blade, check the condition
and operation of the lower blade guard to assure that it is
working properly. Make sure it moves freely and does not
touch the blade or any other part, in all angles and depths
of cut.
3. Place outer clamp washer
beveled edge facing out. Make sure the 30 mm diameter on
the blade side of the clamp fits into the 30 mm hole in the
saw blade to ensure centreing of the blade.
4. Thread the blade clamping screw
by hand (screw has right-hand threads and must be turned
clockwise to tighten).
5. Depress the blade lock
with the blade wrench
compartment, until the blade lock engages and the blade
stops rotating.
6. Tighten the blade clamping screw firmly with the
blade wrench.
NOTICE: Never engage the blade lock while saw is
running, or engage in an effort to stop the tool. Never
turn the saw on while the blade lock is engaged. Serious
damage to your saw will result.
To Replace the blade (Fig. C, D)
1. Remove the battery.
2. To loosen the blade clamping screw
blade lock 11 and turn the saw spindle with the
blade wrench 14 , stored underneath the battery
compartment, until the blade lock engages and the blade
stops rotating. With the blade lock engaged, turn the
blade clamping screw counterclockwise with the blade
wrench (screw has right-hand threads and must be turned
counterclockwise to loosen).
3. Remove the blade clamping screw
washer 16 . Remove old blade.
4. Clean any sawdust that may have accumulated in the
guard or clamp washer area and check the condition
and operation of the lower blade guard as previously
outlined. Do not lubricate this area.
5. Select the proper blade for the application (refer
to Blades). Always use blades that are the correct
size (diameter) with the proper size and shape centre hole
for mounting on the saw spindle. Always assure that the
maximum recommended speed (rpm) on the saw blade
meets or exceeds the speed (rpm) of the saw.
6. Follow steps 1 through 5 under To Install the Blade, making
sure that the blade will rotate in the proper direction.

Lower Blade Guard


WARNING: The lower blade guard is a safety feature
that reduces the risk of serious personal injury. Never
use the saw if the lower guard is missing, damaged,
misassembled or not working properly. Do not rely
on the lower blade guard to protect you under all
circumstances. Your safety depends on following

all warnings and precautions as well as proper
operation of the saw. Check the lower blade guard
for proper closing before each use. If the lower blade
guard is missing or not working properly, have the
saw serviced before using. To assure product safety
and reliability, repair, maintenance and adjustment
should be performed by an authorized service centre
or other qualified service organization, always using
identical replacement parts.
Checking the Lower Guard (Fig. A)
1. Turn tool off and disconnect from power supply.
2. Rotate the lower guard lever (Fig. A,
position to the fully open position.
3. Release the lever and observe the guard
fully closed position.
The tool should be serviced by a qualified service centre if it:
• fails to return to the fully closed position,
• moves intermittently or slowly, or
• contacts the blade or any part of the tool in all angles and
depth of cut.
Blades

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle
material. Foreign objects in the workpiece such as wire or
nails can cause tips to crack or break. Only operate saw
when proper saw blade guard is in place. Mount blade
securely in proper rotation before using, and always use a
clean, sharp blade.

WARNING: Do not cut metal, plastic, concrete, masonry
or fiber cement materials with this saw.

Kickback
Kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, causing an uncontrolled saw to lift up and out of
the workpiece toward the operator. When the blade is pinched
or bound tightly by the kerf closing down, the blade stalls and
the motor reaction drives the unit rapidly back toward the
operator. If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the kerf
and jump back toward the operator.
Kickback is more likely to occur when any of the following
conditions exists.

a. Sagging or improper lifting of the cut off piece can cause
pinching of the blade and lead to kickback.
