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 guard retracting lever
closed position to the fully open position.
3. Release the lever and observe the guard
fully closed position immediately after 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.

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).

Any other conditions which could result in pinching,
binding, twisting, or misalignment of the blade could cause
kickback. Refer to the sections Further Safety Instructions
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 H. This allows the shoe
to support the blade and minimizes twisting and
pinching in the material. See the section titled Depth
of Cut Adjustment.
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.
a. Wet timber
b. Green timber (material freshly cut or not kiln dried)
c. Pressure treated timber (material treated with
preservatives or anti‑rot chemicals)
a. Dull blades cause increased loading of the saw. To
compensate, an operator will usually push harder
which further loads the unit and promotes twisting
of the blade in the kerf. Worn blades may also have
insufficient body clearance which increases the
chance of binding and increased loading.
a. Bevel cuts require special operator attention to proper
cutting techniques – especially guidance of the
saw. Both blade angle to the shoe and greater blade
surface in the material increase the chance for binding
and misalignment (twist) to occur.
JAMMED AgAinsT ThE MATERiAl
a. The saw should be brought up to full operating speed
before starting a cut or restarting a cut after the unit
has been stopped with the blade in the kerf. Failure to
do so can cause stalling and kickback.
