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
correct size replacement blade for your model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.N).
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.
touch the blade or any other part, in all angles and depths
ofcut.
2. Place outer clamp washer
14
on saw spindle with the
large flat surface against the blade and the wording on the
outer clamp washer facing you.
3. Thread blade clamping screw
10
into saw spindle by
hand (screw has right-hand threads and must be turned
clockwise to tighten).
4. Depress the blade lock
3
while turning the saw spindle
with the blade wrench
15
stored underneath the main
handle
2
(Fig.D), until the blade lock 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.
To Replace the Blade (Fig.B–D)
1. To loosen the blade clamping screw
10
, depress the blade
lock
3
and turn the saw spindle with the blade wrench
15
,
stored underneath the main handle
2
, 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).
2. Remove the blade clamping screw
10
and outer clamp
washer
14
. 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 (refer to
Recommended Blade Types under Blades). Always use
blades that are the correct size (7–1/4" [178mm] 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 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
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.
