PARTS INSIDE. Preventive
maintenance performed by unauthorized
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. SERVICEMEN:
Disconnect tool and/or charger from power
source before servicing.
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. 9). 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. 10).
