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 back-
wards, but kickback forces can be controlled by the
operator, if proper precautions are taken.
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 bind-
ing.
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 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.
Do not use dull or damaged saw blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must be
tight and secure before making the cut. If blade adjust-
ment shifts while cutting, it may cause binding and kick-
back.
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
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 acci-
dentally 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 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.
The lower guard may be retracted manually only for
special cuts such as"Tauch- und Winkelschnitten".
"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.
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.
Special safety instructions.
Do not use a damaged power tool. Before each use of
the power tool, check the housing and other compo-
nents for damage such as cracks or breakage.
Only use approved batteries. When using non-compat-
ible batteries, the power tool will not start.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and workshop apron capable of stopping
small abrasive or workpiece fragments. The eye pro-
tection must be capable of stopping flying debris gener-
ated by various operations. The dust mask or respirator
must be capable of filtrating particles generated by your
operation. Prolonged exposure to high intensity noise
may cause hearing loss.
When working at height, block off the area below the
work area and always secure the power tool and the
workpiece against falling.
Only use the power tool on a stable work surface and
ensure a secure footing.
Secure the work piece firmly. A work piece that is
gripped tightly in a clamping device or vice, is more
secure than if held by hand.
While working, the workpiece must be firmly supported
and secured against moving.
Do not attempt to cut extremely small workpieces.
Hold the power tool firmly. High reaction torque can
briefly occur.
Do not work with materials containing magnesium.
Danger of fire.
Do not work with CFRP (carbon-fiber-reinforced poly-
mer) and materials containing asbestos. These materi-
als are considered carcinogenic.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective.
Do not use accessories which are not specifically
designed and recommended by the power tool manu-
facturer. Safe operation is not ensured merely because
an accessory fits your power tool.
Clean the ventilation openings on the power tool at reg-
ular intervals using non-metal tools. The blower of the
motor draws dust into the housing. An excessive accu-
mulation of metallic dust can cause an electrical hazard.
Never look or stare into the light of the power tool's
lamp from a short distance. Never point the light of the
lamp into the eyes of other persons in close vicinity.
The radiation produced by the lamp can be harmful for
the eye.
Do not direct the power tool against yourself, other per-
sons or animals. Danger of injury from sharp or hot
application tools.
Remove the battery before carrying out any adjust-
ments or maintenance on the power tool.
Do not use grinding discs.
