To avoid accidents, always disconnect battery pack from tool before cleaning
or performing any maintenance.
Service
All tool service should be
performed by a Bosch Fac-
tory Service Center or an Authorized Bosch
Service Station. Preventive maintenance per-
formed by unauthorized personnel may result in
misplacing of internal wires and components
which could cause serious hazard.
Batteries
Be alert for battery packs that are nearing
their end of life. If you notice decreased tool
performance or significantly shorter running
time between charges then it is time to replace
the battery pack. Failure to do so can cause the
tool to operate improperly or damage the char-
ger.
Care of Blades
Blades become dull even from cutting regular
lumber. If you find yourself forcing the saw for-
ward to cut instead of just guiding it through the
cut, chances are the blade is dull or coated with
wood pitch.
When cleaning gum and wood pitch from blade,
unplug the saw and remove the blade. Remem-
ber, blades are designed to cut, so handle care-
fully. Wipe the blade with kerosene or similar
solvent to remove the gum and pitch. Unless
you are experienced in sharpening blades, we
recommend you do not try.
Tool Lubrication
Preventive maintenance performed by unau-
thorized personnel may result in misplacing
of internal wires and components which could
cause serious hazard. We recommend that all
tool service be performed by a Bosch factory
Service Center or Authorized Bosch Service
Station.
Periodically lubricate moving parts with a sili-
cone, or light oil spray. Do not use grease be-
cause it tends to attract and hold sawdust.

Bearings
All bearings in this tool are lubricated with a suf-
ficient amount of high-grade lubricant for the life
of the unit under normal operating conditions.
No further lubrication is required.
Cleaning
Certain cleaning agents and
solvents
parts. Some of these are: gasoline, carbon tet-
rachloride, chlorinated cleaning solvents, am-
monia and household detergents that contain
ammonia.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Use a
brush to remove dust and debris from the vent
openings and the guard mechanisms. Do not
attempt to clean by inserting pointed objects
through openings.
Regularly check to make sure the lower guard
and all moving parts are working properly. Regu-
larly check that the lower guard can move from
the fully open to fully closed position without
interference. Ensure that the lower guard moves
to the fully closed position when the Main Han-
dle is moved to the raised position.
