Lower Blade Guard - Craftsman CMCS505 Instruction Manual

1. Retract the lower blade guard
saw spindle against the inner clamp washer
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.
2. Place outer clamp washer
large flat surface against the blade with beveled side
facing out.
3. Thread blade clamping screw
hand (screw has left‑hand threads and must be turned
counterclockwise to tighten).
4. Depress the blade lock button
spindle with the blade wrench
engages and the blade stops rotating.
5. 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.

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.

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
fully 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.
Do not use abrasive wheels or blades. A dull blade will cause
slow inefficient cutting, overload on the saw motor, excessive
splintering, and could increase the possibility of kickback.
Please refer to the table below to determine the correct size
replacement blade for your model saw.
Blade Diameter
5-3/8" (137 mm)
5-3/8" (137 mm)
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
