Maintenance - Bosch GSS20-40 Operating/Safety Instructions Manual

SERVICE
NO
ABLE
Preventive maintenance performed by un-
au thorized personnel may result in mis-
placing of internal wires and components
which could cause serious hazard. We
recom mend that all tool service be performed
by a Bosch Factory Service Center or Autho-
rized Bosch Service Station. SERVICE MEN:
Disconnect tool and/or charger from power
source before servicing.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready for 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 de-
pendable service. To maintain peak efficiency
of the motor, we recommend every two to six
months the brush es be examined. Only genu-
ine Bosch replace ment brushes specially de-
signed for your tool should be used.
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 exces-
sive voltage drop, loss of power or overheat-
ing. Grounded tools must use 3-wire exten-
sion cords that have 3-prong plugs and
receptacles.
