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.
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
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-
wire extension cords that have 3-prong
plugs and receptacles.
NOTE: The smaller the gauge number, the heavier
the cord.

Maintenance
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
hazard. We 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.
CAUTION
!
plastic parts. Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household detergents
that contain ammonia.
Blades become dull even from cutting regular
lumber. If you find yourself forcing the saw
forward to cut instead of just guiding it
through the cut, chances are the blade is dull
or coated with wood pitch.
When cleaning gum and wood pitch from
blade, unplug the saw and remove the blade.
Remember, blades are designed to cut, so
handle carefully. Wipe the blade with
kerosene or similar solvent to remove the gum
and pitch. Unless you are experienced in
sharpening blades, we recommend you do
not try.
