Kickback is the result of saw misuse and/or incorrect oper-
ating procedures or conditions and can be avoided by
taking proper precautions as given below.
 Maintain a firm grip on the saw and position
your arms to allow you to resist kickback
force. Always stay to the side of the saw
blade, never putting the saw blade in line with
your body. The saw can jump backwards in the event
of kickback, but the operator can control kickback force 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 binding.
 When restarting a saw in the workpiece, cen-
tre 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.
 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 blades. Unsharp-
ened or improperly set blades produce narrow kerf caus-
ing excessive friction, blade binding and kickback.
 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.
 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 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 posi-
tion. 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 may be retracted manually only
for special cuts such as "plunge cuts" and "com-
pound cuts". Raise lower guard by retracting
handle and as soon as blade enters the mate-
rial, the lower guard must be released. For all
other sawing, the lower guard should operate automati-
cally.
 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 whatever is in
its path. Be aware of the time it takes for the blade to stop
after switch is released.

Additional safety warnings

 Do not reach into the chip ejector with your
hands. They could be injured by rotating parts.
 Do not work overhead with the saw. In this man-
ner you do not have sufficient control over the power tool.
 Use appropriate detectors to determine if util-
ity 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. Penetrating a water line
causes property damage.
 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.
 Do not saw ferrous metals. Red hot chips can ignite
the dust extraction.
 Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than by
hand.
 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.
 Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e.g.,
against continuous intense sunlight, fire,
water, and moisture. Danger of explosion.
 In case of damage and improper use of the
battery, vapours may be emitted. Ventilate
the area and seek medical help in case of com-
plaints. The vapours can irritate the respiratory system.
 Use the battery only in conjunction with your
Würth power tool. This measure alone protects the
battery against dangerous overload.
 The battery can be damaged by pointed objects
such as nails or screwdrivers or by force
applied externally. An internal short circuit can occur
and the battery can burn, smoke, explode or overheat.
