SAFETY INSTRUCTIONS
SPECIFIC SAFETY RULES FOR
CIRCULAR SAWS
DANGER:
Keep hands away from
cutting area and blade. Keep your second
hand on auxillary handle, or motor housing.
If both hands are holding the saw, they
cannot be cut by the blade.
1. Do not reach underneath the work
piece. The guard cannot protect you from
the blade below the work piece.
2. Adjust the cutting depth to the thickness
of the work piece.. Less than a full tooth of
the blade teeth should be visible below the
work piece.
3. Never hold piece 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
exposure, blade binding, or loss of control.
4. 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.
5. When ripping always use a rip fence or
straight edge guide (sold separately). This
improves the accuracy of cut and reduces
the chance of blade binding.
6. Always use blades with correct size
and shape (diamond versus round) of
arbor holes. Blades that do not match the
mounting hardware of the saw will run
eccentrically, causing loss of control.
7. 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.
CAUSES AND OPERATOR
PREVENTION OF KICKBACK
Kickback is 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 if the wood
causing the blade to climb out the kerf and
jump back toward the operator.
Kickback is the result of saw misuse and/or
incorrect operation procedures or conditions
and can be avoided by taking proper
precautions as given below.
1. 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.
2. 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.
3. When restarting a saw in the work
piece, centre the saw blade in the kerfs and
check that saw teeth are not engaged into
the material. If saw blade is binding, It may
walk up or kickback from the work piece as
the saw is restarted.
