better and safer at the rate for which it
was designed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the switch
is dangerous and must be repaired.
c) Disconnect the plug from the power
source and/or the battery pack from
the power tool before making any
adjustments, changing accessories, or
storing power tools. Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach
of children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool's operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and
tool bits etc., in accordance with these
instructions taking into account the
working conditions and the work to
be performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
5) SERVICE
a) 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.

ADDITIONAL SPECIFIC SAFETY RULES

Safety instructions for all saws

a) 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.
b) Do not reach underneath the workpiece.
The guard cannot protect you from the blade
below the workpiece.
c) 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.
d) 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.
e) Hold 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 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
arbour 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.
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:
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
