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 centering of the blade.
4. Thread the blade clamping screw
spindle by hand (screw has right-hand threads and must be
turned clockwise to tighten).
5. Depress the blade lock

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. A, D, E)
1. Remove the battery.
2. To loosen the blade clamping screw

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

. 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 center 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 center or other
qualified service organization, always using identical

Checking the Lower Guard (Fig. A)
1. Turn tool off and disconnect from power supply.
2. Rotate the lower guard retracting lever
closed 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 center 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.
1. iMPROPER WORKPiECE sUPPORT
a. Sagging or improper lifting of the cut off piece can cause
pinching of the blade and lead to kickback.
b. Cutting through material supported at the outer ends
only can cause kickback. As the material weakens it sags,
closing down the kerf and pinching the blade (Fig. L).
c. Cutting off a cantilevered or overhanging piece of
material from the bottom up in a vertical direction can
cause kickback. The falling cut off piece can pinch the blade.
d. Cutting off long narrow strips (as in ripping) can cause
kickback. The cut off strip can sag or twist closing the kerf
and pinching the blade.
e. Snagging the lower guard on a surface below the
material being cut momentarily reduces operator
control. The saw can lift partially out of the cut increasing
the chance of blade twist.
