b 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.
c When restarting a saw in the workpiece,
centre the saw blade in the kerf and check 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.
d 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.
e Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
f 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.
g 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.
Safety instructions for saws with a pendulum
blade guard
a 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 open position. If saw is accidentally
dropped, 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.
b 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.
c Lower guard should be retracted manually
only for special cuts such as „plunge cuts"
and „compound cuts." Raise lower guard by
retracting handle and as soon as blade enters
the material, the lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
d Always observe that the lower guard is
covering the blade before placing 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.
Additional safety instructions for all saws with
riving knife
a Use the appropriate riving knife for the blade
being used. For the riving knife to work, it must
be thicker than the body of the blade but thinner
than the tooth set of the blade.
b Adjust the riving knife as described in this
instruction manual. Incorrect spacing,
positioning and alignment can make the riving
knife ineffective in preventing kickback.
c Always use the riving knife except when
plunge cutting. Riving knife must be replaced
after plunge cutting. Riving knife causes
interference during plunge cutting and can create
kickback.
d For the riving knife to work, it must be
engaged in the workpiece. The riving knife is
ineffective in preventing kickback during short cuts.
e Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
Additional safety instructions for circular saws
• Wear ear protectors. Exposure to noise can
cause hearing loss.
• Preferably wear a dust mask.
• Do not use blades of larger or smaller diameter
than recommended. For the proper blade rating
refer to the technical data. Use only the blades
specified in this manual, complying with EN 847-1.
• Never use abrasive cut-off wheels.
