use. Many accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions and
the work to be performed. Use of the power
tool for operations different from those intended
could result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe
handling and control of the tool in unexpected
situations.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the
power tool is maintained.

Cutting procedures
8
a) DANGER: Keep hands away from cutting
area and the blade. If both hands are
holding the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below
the workpiece.
c) 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.
d) Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. It is important
to support the work properly to minimise body
exposure, blade binding, or loss of control.
e) Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will also
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
f) When ripping, always use a rip fence or straight
edge guide. This improves the accuracy of cut
and reduces the chance of blade binding.
g) 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 off-centre, causing loss of control.
h) Never use damaged or incorrect blade washers
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,
jammed 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 jammed 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 incorrect
operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm grip 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 kickback forces can be
controlled by the operator, if proper precautions
are taken.
b) 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.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material. If a saw
blade binds, it may walk up or kickback from the
workpiece as the saw is restarted.
d) 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.
e) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf
causing excessive friction, blade binding and
kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making the cut.
If blade adjustment shifts while cutting, it may
cause binding and kickback.
