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 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.
Hold the power tool by insulated gripping surfaces, 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 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.
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.
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 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 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.
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 the
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.
Lower guard function
Check the lower guard for proper closing before each use. Do not operate the saw if the
lower guard does not move freely and close instantly. Never clamp or tie the lower guard
into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the
