Service
1.
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
2. Follow instruction for lubricating and chang-
ing accessories.
3. Keep handles dry, clean and free from oil and
grease.

Cutting procedures
1. DANGER: Keep hands away from cutting
area and the blade. Keep your second hand
on auxiliary handle, or motor housing. If both
hands are holding the saw, they cannot be cut by
the blade.
2. Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
3. Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the blade
teeth should be visible below the workpiece.
4. Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a
stable platform. It is important to support the
work properly to minimize body exposure, blade
binding, or loss of control.
5. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
6. When ripping, always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding.
7. Always use blades with correct size and shape

(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of
control.
8. Never use damaged or incorrect blade wash-
ers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
Kickback causes and related warnings
— 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
operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
1.
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
kickback forces can be controlled by the operator,
if proper precautions are taken.
2. 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 attempt
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.
3. 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.
4. 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.
