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.
BLADE GUIDE LUBRICATION
The blade guides are lubricated at the
factory. Should relubrication be necessary, a
light mineral oil grease may be applied
sparingly

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.

necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used. This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-
wire extension cords that have 3-prong
plugs and receptacles.
NOTE: The smaller the gauge number, the
heavier the cord.
Maintenance
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Authorized Bosch Service Station.
Bearings which become noisy (due to heavy
hazard. We

be replaced at once to avoid overheating or
motor failure.
