orized 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

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

2. If heavier pressures are used, the wires will be
overstressed, resulting in a wiping action; and if
this is continued, the life of the brush will be
shortened due to wire fatigue.

as much of the brush face as possible is in full
contact with the work. Applying the side or edge of
the brush to the work will result in wire breakage
and shortened brush life.

Bearings which become noisy (due to heavy load or very abrasive material cut ting) should

motor failure.
Cleaning
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
