• Do not reach underneath the workpiece.
The guard cannot protect you from the
blade below the workpiece.
• 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.
• 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 minimise body
exposure, blade binding, or loss of control.
• Hold the power tool by its 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.
• When ripping, always use a rip fence or
straight edge guide.
This improves the accuracy of cut and
reduces the chance of blade binding.
• Always use saw 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.
• Never use damaged or incorrect blade
washers or bolts.
The blade washers and bolt were specially
designed for your saw, for optimum
performance and safety of operation.

Kickback causes and related warnings
A 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 the result of saw misuse and/or
incorrect 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 kickback 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 attempt to remove
the saw from the work or pull the saw
backwards 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.
Unsharpened 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.
