To Replace the Blade (Fig. A, B)

WARNING: Remove battery before service, adjustment,
installing or removing accessories.
1. To loosen the blade clamping screw

wrench 13 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).
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.
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.

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.
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.
2. iMPROPER DEPTh OF CUT sETTing On sAW
a. To make the most efficient cut, the blade should protrude
only far enough to expose one‑half of a tooth. This allows
the shoe to support the blade and minimizes twisting and
pinching in the material. See the section titled Cutting
Depth Adjustment.
3. BlADE TWisTing (MisAlignMEnT in CUT)
a. Pushing harder to cut through a knot, a nail or a hard
grain area can cause the blade to twist.
b. Trying to turn the saw in the cut (trying to get back on the
marked line) can cause blade twist.
c. Overreaching or operating the saw with poor body
control (out of balance), can result in twisting the blade.
d. Changing hand grip or body position while cutting can
result in blade twist.
e. Backing up the saw to clear blade can lead to twist.
4. MATERiAls ThAT REQUiRE EXTRA ATTEnTiOn
a. Wet lumber
b. Green lumber (material freshly cut or not kiln dried)
c. Pressure treated lumber (material treated with
preservatives or anti‑rot chemicals)
