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.
Lower Blade Guard
WARNING: The lower blade guard is a safety
feature which reduces the risk of serious personal
injury. Never use the saw if the lower blade
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 lower blade guard
for proper closing before each use as outlined
in
Further safety instructions for All saws .
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 replacement parts.
Checking the Lower Guard (Fig. A)
1. Turn tool off and disconnect from power supply.
2. Rotate the lower blade guard retracting lever
6 from the
fully closed position to the fully open position.
3. Release the lever and observe the guard 7 return to the
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.
2. Remove the blade clamping screw 8 and outer clamp
washer 18 only. Remove old blade.
3. 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.
4. Select the proper blade for the application (see 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.
5. Follow steps 2 through 6 under To Install the
Blade , making sure that the blade will rotate in the
proper direction.
Changing Blades
To Install the Blade (Fig. A, D)
WARNING: Remove battery before service,
adjustment, installing or removing accessories.
1. Place inner clamp washer
19
on saw
spindle 16 properly.
2. Retract the lower blade guard
7
and place blade
15
on
saw spindle against the inner clamp washer 19 , making
sure that the blade will rotate in the proper direction (the
direction of the rotation arrow on the saw blade and the
teeth must point in the same direction as the direction of
rotation arrow on the lower blade guard). Do 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 18 on saw spindle with the
large flat surface against the blade with beveled side
facing out.
4. Thread blade clamping screw 8 into saw spindle by
hand (screw has left‑hand threads and must be turned
counterclockwise to tighten).
5. Depress the blade lock button
20
while turning the saw
spindle with the blade wrench 14 until the blade lock
engages and the blade stops rotating.
6. Tighten the blade clamping screw firmly with the
blade wrench.
nOTE:
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)
WARNING: Remove battery before service, adjustment,
installing or removing accessories.
1. To loosen the blade clamping screw 8 , depress the
blade lock button 20 and turn the saw spindle with
the blade wrench 14 until the blade lock engages and
the blade stops rotating. With the blade lock engaged,
turn the blade clamping screw clockwise with the blade
wrench (screw has left‑hand threads and must be turned
clockwise to loosen).
