Kickback causes and related warnings
– Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an un-
controlled 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 the result of saw misuse and/or incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
• Maintain a firm grip with both hands on the
saw and position your arms to resist kickback
forces. Position your body to either side of the
blade, but not in line with the blade. Kickback
could cause the saw to jump backwards, but kick-
back forces can be controlled by the operator, if
proper precautions are taken.

Kickback
• When blade is binding, or when interrupting
a cut for any reason, release the trigger and
hold the saw motionless in the material until
the blade comes to a complete stop. Never at-
tempt to remove the saw from the work or pull
the saw backward while the blade is in motion
or kickback may occur. Investigate and take
corrective actions to eliminate the cause of blade
binding.
• When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from
the workpiece as the saw is restarted.
• Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.

4. To increase the angle of cut up to 60˚, push in
the override button and tip the saw to the desired
angle.
5. Push down miter lever to lock. Check angle with
a square. Also check to be sure miter adjusting
lever is secure before cutting.
Adjusting the Blade to Shoe
The shoe has been adjusted at the factory to a 90
degree setting. Inspect the saw regularly to make
sure the blade is 90 degrees to the shoe.
1. Unplug tool.
2. Set the bevel pointer to zero.
3. To make sure the blade is 90 degrees to the
shoe, place saw on the blade side and retract
lower guard. Place a square against the blade
and shoe to inspect the degree setting (Fig. 5).
4. To adjust the degree setting, loosen the bevel
adjusting knob. Turn the bevel adjustment screw
in or out until the blade is at a 90 degree angle
with the shoe.
5. Tighten the bevel adjusting knob securely.
