OPERATION
WARNING To reduce the risk of injury,
keep hands away from the blade and other
moving parts. Always wear safety goggles or
glasses with side shields. Use only speci-
cally recommended accessories. Others may
be hazardous.
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. Remove battery pack.
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.
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 adjust-
ing knob securely.
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
Bevel
Adjustment
Screw
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.
• Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding and
kickback.
• Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
• Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
General Operation
Always clamp the workpiece securely on a saw
horse or bench. See “APPLICATIONS” for the cor-
rect way to support your work in different situations.
1. Draw a cutting line. Place the front of the shoe on
the edge of the workpiece without making blade
contact. Hold the handle with one hand and the
front handle with the other (Fig. 4).

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 rm 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.
• 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

4. Tighten the bevel adjusting knob securely.
Adjusting Bevel Angle
1. Remove battery pack.
2. To adjust the angle of the cut, hold the saw by
the handle and loosen the bevel adjusting knob.
3. Hold the front of the shoe and rotate the saw by
the handle to the desired angle as indicated by
the markings on the bevel scale (Fig. 3).
