Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions may result in electric
shock, fire and/or serious injury.
Save all warnings and instructions for future ref-
erence.
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.
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 the workpiece being cut in your
hands or across your leg. Secure the work-
piece to a stable platform. It is important to
support the work properly to minimize body ex-
posure, blade binding, or loss of control.
Hold the power tool by insulated gripping sur-
faces, when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a „live" wire will also make ex-
posed 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 accura-
cy of cut and reduces the chance of blade bind-
ing.
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 wash-
ers or bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
Causes and operator prevention of kickback:
– Kickback is a sudden reaction to a pinched,
bound or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the work-
piece 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.

Safety warnings for circular saws
– If the blade becomes twisted or misaligned in
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:
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.
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 oper-
ator, 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
the saw backward while the blade is in mo-
tion or kickback may occur. Investigate and
take corrective actions to eliminate the cause of
blade binding.
When restarting a saw in the workpiece, cen-
tre 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. Unsharp-
ened or improperly set blades produce narrow
kerf causing excessive friction, blade binding
and kickback.
Blade depth and bevel adjusting locking le-
vers must be tight and secure before making
cut. If blade adjustment shifts while cutting, it
may cause binding and kickback.
Use extra caution when making a "plunge
cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause kickback.
