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.
Your tool is equipped with a Pop-out brush
system. The tool will shut off when brush
replacement, lubrication and preventive
maintenance are needed.
Only genuine Bosch replace ment brushes
specially designed for your tool should be
used.
BEARINGS
Every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Au thorized Bosch Service Station.
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.
Maintenance
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
higher the cord capacity.
