Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kick-
back.
Blade depth and bevel adjusting locking
levers must be tight and secure before mak-
ing cut. If blade adjustment shifts while cutting, it
may cause binding and kickback.
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.
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.
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.
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.
Always observe that the lower guard is cover-
ing the blade before placing saw down on
bench or floor. An unprotected, coasting blade
will cause the saw to walk backwards, cutting what-
ever is in its path. Be aware of the time it takes for
the blade to stop after switch is released.
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.
Adjust the riving knife as described in this
instruction manual. Incorrect spacing, position-
ing and alignment can make the riving knife ineffec-
tive in preventing kickback.
Always use the riving knife except when
plunge cutting. Riving knife must be replaced after
plunge cutting. Riving knife causes interference dur-
ing 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 riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
Do not reach into the saw dust ejector with
your hands. They could be injured by rotating
parts.
Do not work overhead with the saw. In this
manner you do not have sufficient control over the
power tool.
Use suitable detectors to determine if utility
lines are hidden in the work area or call the
local utility company for assistance. Contact
with electric lines can lead to fire and electric shock.
Damaging a gas line can lead to explosion. Pene-
trating a water line causes property damage or may
cause an electric shock.
Do not operate the power tool stationary. It is
not designed for operation with a saw table.
Do not use high speed steel (HSS) saw
blades. Such saw blades can easily break.
When working with the machine, always hold
it firmly with both hands and provide for a
secure stance. The power tool is guided more
secure with both hands.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
Do not work materials containing asbestos.
Asbestos is considered carcinogenic.
Take protective measures when dust can
develop during working that is harmful to
one's health, combustible or explosive. Exam-
ple: Some dusts are regarded as carcinogenic.
Wear a dust mask and work with dust/chip extrac-
tion when connectable.
Always wait until the machine has come to a
complete stop before placing it down. The tool
insert can jam and lead to loss of control over the
power tool.
Never use the machine with a damaged cable.
Do not touch the damaged cable and pull the
mains plug when the cable is damaged while
working. Damaged cables increase the risk of an
electric shock.
Connect machines that are used in the open
via a residual current device (RCD).
