Instruction & User Manual
m
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.
m
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.
m
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.
m
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.
m
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.
m
Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
m
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.
m
Use extra caution when sawing into
existing walls or other blind areas.
The protruding blade may cut objects that
can cause kickback.
Lower Guard Function
m
Check the lower guard for proper
closing before each use. Do not
operate the saw if the lower guard
does not move freely and close
instantly. Never clamp or tie the
lower guard into the open position.
If the 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, in all
angles and depths of cut.
