performed
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 Authorized Bosch Service Station.
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.
Periodically lubricate moving parts with a silicone, or
light oil spray. Do not use grease because it tends to
attract and hold sawdust.

All bearings in this tool are lubricated with a sufficient
amount of high-grade lubricant for the life of the unit
under normal operating conditions. No further
lubrication is required.
