5. Hold power
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.
6. When ripping always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance for 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 use damaged
washers or bolts. The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.
9. 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.
(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
precautions are taken.
(2) When blade
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 workpiece,
center the saw blade in the kerf and check

10. Check lower guard for proper closing before
each use. Do not operate the saw if lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the

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
of blade pinching and kickback. Large
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 avoid kickback, do support
board or panel near the cut.
Do not support board or
panel away from the cut.
Do not use dull or damaged blades.
Unsharpened or improperly set
produce narrow kerf causing excessive
friction, blade binding and kickback.
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 making a "plunge
cut" into existing walls or other blind
areas. The protruding blade may cut objects
that can cause kickback.
