SAFETY INSTRUCTIONS
SERVICE
1. Have your power tool serviced by
a qualified repair person using only
identical replacement parts. This will
ensure that the safety of the power tool
is maintained.
SPECIFIC SAFETY RULES FOR
CIRCULAR SAWS
1. Danger
a) Keep hands away from cutting area
and 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.
b) Do not reach underneath the work
piece. The guard cannot protect you
from the blade below the work piece.
c) 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.
d) 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.
e) 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.
f) When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance
of blade binding.
g) 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.
h) 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.
2. Causes and operator prevention
of kickback
a) 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;
b) 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;
c) 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.
3. 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.
a) 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.
b) 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.
c) 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.
