Maintenance
Service
NO USER SERVICE -
ABLE PARTS INSIDE.
Preven tive maintenance performed by
un au thorized personnel may result in
misplacing of internal wires and
components which could cause serious
hazard. We recom mend that all tool
service be performed by a Bosch
Factory Service Center or Authorized
Bosch Service Station.
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 charger.
Tool Lubrication
Your Bosch tool has been properly
lubricated and is ready for use.
D.C. Motors
The motor in your tool has been
engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend
it be examined every six months. Only a
genuine Bosch replacement motor
specially designed for your tool should
be used.
Drive Belt
The drive belt is a normal maintenance
part and should be inspected
periodically for wear. If the drive belt
shows signs of drying out, cracking or
tearing, it should be replaced. If the
drive belt will not track properly or
comes off the pulleys, it should be
replaced.
Installing new drive belt: Loosen
screws and remove the drive belt cover
(Fig. 12). Cut and remove the worn
drive belt. Before installing the new
drive belt, clean both pulleys
thoroughly. First place the new drive
belt onto the drive pulley then rotate
clockwise while pushing the belt onto
the driven pulley. Reinstall the drive
belt cover and securely tighten screws
(Fig. 13).
Cleaning
Certain cleaning
agents and solvents
damage plastic parts. Some of these
are: gasoline, car bon tetrachloride,
chlorinated cleaning solvents, ammonia
and household detergents that contain
ammonia.
Ventilation openings and switch levers
must be kept clean and free of foreign
matter. Do not attempt to clean by
inserting pointed objects through
opening.
