Service
Preventive maintenance
performed by unauth-
orized personnel 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.
Cleaning
To avoid accidents always
disconnect the tool from
the power supply before cleaning or
performing any maintenance. The tool may
be cleaned most effectively with compressed
dry air.
Always wear safety goggles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through openings.
Certain cleaning agents
and solvents damage
plastic parts. Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household
detergents that contain ammonia.

Maintenance
! CAUTION
If an extension cord is
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.
The length of the vacuum cleaner cord must be
included in calculating the total length of cord.
