 When blade is binding, or when interrupting a cut for
any reason, release the trigger and hold the saw mo-
tionless 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 backward while the blade is in mo-
tion or kickback may occur. Investigate and take correc-
tive actions to eliminate the cause of blade binding.
 When restarting a saw in the workpiece, centre the saw
blade in the kerf and check that saw teeth are not en-
gaged into the material. If saw blade is binding, it may
walk up or kickback from the workpiece as the saw is re-
started.
 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 pan-
el on both sides, near the line of cut and near the edge of
the panel.
 Do not use dull or damaged blades. Unsharpened or im-
properly 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 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 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.
 The lower guard may be retracted manually only for
special cuts such as "plunge cuts and angle cuts". Raise
the lower guard by retracting the handle and as soon as
the blade enters the material, release the lower guard.
For all other sawing operations, the lower guard should op-
erate automatically.
 Always observe that the lower guard is covering the
blade before placing saw down on bench or floor. An un-
protected, 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 switch is released.
Additional safety warnings
 Do not work overhead with the saw. In this manner you
do not have sufficient control over the power tool.
 Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
Bosch Power Tools
pany 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 dam-
age.
 Do not operate the power tool stationary. It is not de-
signed 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 clamp-
ing 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, va-
pours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can irri-
tate the respiratory system.
 Use the battery only in conjunction with your Bosch
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.
