KICKBACK CAUSES AND RELATED
WARNINGS
Kickback is a sudden reaction to a pinched, jammed 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 jammed 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 operat-
ing 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 by the
operator, if proper 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 so that the saw teeth are not
engaged into the material. If a saw blade binds, 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.
Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing ex-
cessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must
be tight and secure before making the 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.
TRACK SAW SAFETY WARNINGS
GUARD FUNCTION
Check the guard for proper closing before each use.
Do not operate the saw if the guard does not move
freely and enclose the blade instantly. Never clamp or
tie the guard so that the blade is exposed. If the saw
is accidentally dropped, the guard may be bent. Check
to make sure that the guard moves freely and does not
touch the blade or any other part, in all angles and depths
of cut.
Check the operation and condition of the guard return
spring. If the guard and the spring are not operating
properly, they must be serviced before use. The guard
may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
Assure that the base plate of the saw will not shift while
performing a "plunge cut". Blade shifting sideways will
cause binding and likely kick back.
Always observe that the guard is covering the blade
before placing the 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 the switch is
released.
Do not use abrasive wheels with this saw.
Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and
may lead to loss of control.
RIVING KNIFE FUNCTION
Use the appropriate saw blade for the riving knife. For
the riving knife to function, the body of the blade must
be thinner than the riving knife and the cutting width of
the blade must be wider than the thickness of the riving
knife.
Adjust the riving knife as described in this instruction
manual. Incorrect spacing, positioning and alignment can
make the riving knife ineffective in preventing kickback.
Always use the riving knife, except when plunge
cutting. The riving knife must be replaced after plunge
cutting. The riving knife causes interference during plunge
cutting and can create kickback.
For the riving knife to work, it must be engaged in the
workpiece. The riving knife is ineffective in preventing
kickback during short cuts.
Do not operate the saw if the riving knife is bent. Even
a light interference can slow the closing rate of a guard.
Use the appropriate saw blade for the riving knife.
For the riving knife to function properly, the body of the
saw blade must be thicker than 1.0 mm and the cutting
width of the saw blade must be wider than 1.4 mm.
