will also make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
6. When ripping, always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding.
7. 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.
8. Never
washers or bolt. The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.
9. Kickback causes and related warnings
− 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
precautions are taken.
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

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.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the
saw on the workpiece, the saw should be rested on
the larger portion and the smaller piece cut off.

To avoid kickback, do support
board or panel near the cut.

produce narrow kerf causing excessive friction,

and clean. Gum and wood pitch hardened on
blades slows saw and increases potential for
kickback. Keep blade clean by first removing it
from tool, then cleaning it with gum and pitch
remover, hot water or kerosene. Never use
gasoline.
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.
Use extra caution when sawing into
•
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.
ALWAYS hold the tool firmly with both
•
hands. NEVER place your hand or fingers
behind the saw. If kickback occurs, the saw
could easily jump backwards over your hand,
leading to serious personal injury.
