ADDITIONAL SAFETY INSTRUCTIONS FOR
CIRCULAR SAWS
DANGER! 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.
• Keep your body positioned to either side of the saw blade, but not in line with
the saw blade. KICKBACK could cause the saw to jump backwards. (See
‘Causes and Operator Prevention of Kickback.’)
• Do not reach underneath the work. The guard can not protect you from the
blade below the work.
• Check lower guard for proper closing before each use. Do not operate saw if
lower guard does not move freely and close instantly. Never clamp or tie the
lower guard into the open position. If saw is accidentally dropped, the lower
guard may be bent. Raise the lower guard with the Retracting Handle and make
sure it moves freely and does not touch the blade or any other part, at all angles
and depths of cut.
• Check the operation and condition of the lower guard spring. If the guard and
the spring are not operating properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts, gummy deposits, or a
build-up of debris.
• Lower guard should be retracted manually only for special cuts such as ‘Pocket
Cuts’ and ‘Compound Cuts.’ Raise lower guard by Retracting Handle. As soon
as blade enters the material, lower guard must be released. For all other
sawing, the lower guard should operate automatically.
• Always observe that the lower guard is covering the blade before placing saw
down on bench or floor. An unprotected, coasting blade will cause the saw to
walk backwards, cutting whatever is in its path. Be aware of the time it takes
for the blade to stop after switch is released.
• NEVER hold piece being cut in your hands or across your leg. It is important to
support the work properly to minimise body exposure, blade binding, or loss of
control.
• Hold 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 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 for blade binding.
• Always use blades with correct size and shape (diamond vs. round) arbor
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 bolts. 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 tool misuse and/or incorrect operating procedures
or conditions and can be avoided by taking proper precautions as given below:
