Tool Lubrication
Your Bosch tool has been properly
lubricated and is ready for use.
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 specially designed for your tool
should be used.
Bearings
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
load or very abrasive material cutting)
should be replaced at once to avoid
overheating or motor failure.
