English
– 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 in­
correct 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 ei­
ther 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 pre­
cautions are taken.
– When blade is binding, or when interrupt­
ing a cut for any reason, release the trig­
ger and hold the saw motionless in the
material until the blade comes to a com­
plete stop. Never attempt to remove the
saw from the work or pull the saw back­
ward while the blade is in motion or kick­
back may occur. Investigate and take cor­
rective 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 pan­
els 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. Un­
sharpened or improperly set blades pro­
duce narrow kerf causing excessive fric­
tion, 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 exist­
–
ing walls or other blind areas. The pro­
truding blade may cut objects that can
cause kickback.

Lower guard function
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.
– 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 de­
bris.
– 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 back­
wards, cutting whatever is in its path. Be
aware of the time it takes for the blade to
stop after the switch is released.
Riving knife function
Use the appropriate saw blade for the riv­
–
ing 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,posi­
tioning and alignment can make the riving
knife ineffective in preventing kickback.
For the riving knife to work, it must be en­
–
gaged 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.
