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 workpiece 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 by
the
operator,
if proper precautions are taken.
2.
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.
3.
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.
4.
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.
5.
Do not use dull or damaged blades.
Unsharpened or improperly set
blades
produce
narrow
kerf
causing
excessive friction, blade binding and
kickback.
6.
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.
7.
Use extra caution when sawing into existing
walls or other blind areas.
The protruding blade
may cut
objects
that
can
cause
kickback.
8.
ALWAYS hold the tool firmly with both hands.
NEVER place your hand, leg or any part of
your body under the tool base or behind the
saw, especially when making cross-cuts.
If
kickback occurs, the
saw
could
easily
jump
backwards over
your
hand,
leading
to
serious
personal
injury.
9.
Never force the saw. Push the saw forward at
a speed so that the blade cuts without
slowing.
Forcing the saw can cause uneven
cuts, loss of accuracy,
and
possible
kickback.
Lower guard function
1.
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.
2.
Check the operation 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.
3.
The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts”. Raise the lower guard
by the retracting handle and as soon as the
blade enters the material, the lower guard
must be released.
For all other sawing, the
lower guard
should
operate
automatically.
4.
Always observe that the lower 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 switch is released.
