DIRECTION OF CUT
HARD AUXILIARY
CONTROL HANDLE
When making a cut in sheet metal,
masonry, etc.: You may start your cut at the
end of the piece or you can plunge cut
somewhere in the body of the material.
In order to try to avoid recoil (a situation where
the wheel wants to skip out of the material) it
is recommended to make cuts in the same
direction as the rotation of the wheel (Fig. 5).
Service
Preventive maintenance
performed by unauthorized
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. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CHUCK LUBRICATION
The wrenchless chuck has been properly
lubricated and is ready to use. If the chuck's
jaws begin to stick during use, the chuck
requires lubrication. To lubricate the chuck,
first remove debris from the inside of the
chuck with compressed air. Apply a pea-
sized amount of general-purpose grease to
the sides of the jaws, and adjust the chuck
through its full range of motion to distribute
the grease.
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 brushes be examined.
Only genuine Bosch replacement 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.
