Service
Preventive maintenance
performed by unauthorized
per so n nel 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 Autho -
rized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brush es be examined.
Only genuine Bosch replace ment brushes
specially designed for your tool should be
used.
BEARINGS
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always
dis connect the tool from
the power supply before cleaning or
performing any main tenance. The tool may
be cleaned most effectively with compressed
dry air.
Always wear safety gog gles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not at tempt to clean by inserting pointed
objects through openings.
Certain cleaning agents
and sol vents damage
plastic parts. Some of these are: gasoline,
carbon tetrachlo ride, chlo rinated cleaning
solvents, ammonia and house hold detergents
that contain ammonia.
Clean the park rest shoe regularly and ensure
that it springs back freely.
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 screw and
remove the drive belt cover (Fig. 11). 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 (Fig. 12). Reinstall
the drive belt cover and securely tighten screw
(Fig. 11).
