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 brushes be examined.
Only genuine Bosch replacement brushes
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 screw and
remove the drive belt cover. 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 screw (Fig. 15).
