P ARTICULAR REQUIREMENTS FOR
CIRCULAR SAWS
Not to use any abrasive wheels.
Ensure that the riving knife is adjusted so that the
distance between the riving knife and the rim of the blade
is not more than 5mm, and the rim of the blade does not
extend more than 5mm beymond the lowest edge of the
riving knife.
Safety instructions for all saws
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.
NOTE: For circular saws with 140 mm or smaller diameter
blades, the "Keep your second hand on auxiliary handle,
or motor housing" may be omitted.
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 minimize body exposure, blade binding, or loss of
control.
Hold 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 shock the
operator.
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 eccentrically, 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.

Further safety instructions for all saws
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 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.
NOTE: For circular saws with 140 mm or smaller
diameter blades, the words "with both hands" may be
omitted.
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 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.
