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
Authorized 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. 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.
Cleaning
To avoid accidents always
disconnect the tool from
the power supply before cleaning or
performing any maintenance. The tool may
be cleaned most effectively with compressed
dry air.
Always wear safety goggles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through openings.

RIP CUTS
The combination blade provided with your saw
is for both cross cuts and rip cuts. Ripping is
cutting lengthwise with the grain of the wood.
Rip cuts are easy to do with a rip fence
(Fig. 11). Rip Fence is available as an accessory
(not included). To attach fence, insert fence
through slots in foot to desired width as shown
and secure with the thumb screw (not
included).
RIP BOARD GUIDE
When rip cutting large sheets, the rip fence
may not allow the desired width of cut.
Clamp or nail a straight piece of 1" (25 mm)
lumber to the sheet as a guide (Fig. 12).
Use the right side of the foot against the
board guide.
