To Replace the Blade (Fig. H, I)
1. To loosen the blade clamping screw
blade lock button
and turn the saw spindle with the
11
blade wrench
until the blade lock engages and the
14
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).
2. Remove the blade clamping screw
washer
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 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 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.
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 direction 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

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.

e
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. Q).
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.
a. To make the most efficient cut, the blade should
protrude only far enough to expose one-half of a
tooth as shown in Figure K. This allows the shoe
to support the blade and minimizes twisting and
