PLUNGE CUTTING
Plunge cutting is useful and time-saving in
making rough openings in softer materials. It is
not necessary to drill a hole for an inside or
pocket cut. Draw lines for the opening, hold the
saw firmly, tilt it forward so that the toe of the
saw foot rests on the work, but with the blade
well clear of the work. Start the motor, and then
very gradually lower the blade. When it
touches, continue pressing down on the toe of
the saw foot slowly pivoting the saw like a
hinge until the blade cuts through and the foot
rests flat on the work. Then saw ahead on the
cutting line. We do not recommend plunge
cutting with a scroll blade (Fig. 7).
To make sharp corners, cut up to the corner,
then back up slightly before rounding the
corner. After the opening is complete, go back
to each corner and cut it from the opposite
direction to square it off. Do not try to plunge
cut into hard materials such as steel.

Service
Preventive maintenance
performed by unauthorized
per so n nel 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.
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 brush es be examined.
Only genuine Bosch replace ment brushes
specially designed for your tool should be
used.
BEARINGS
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always
dis connect the tool from
the power supply before cleaning or
performing any main tenance. The tool may
be cleaned most effectively with compressed
dry air. Always wear safety gog gles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not at tempt to clean by inserting pointed
objects through openings.
Certain cleaning agents
and sol vents damage
plastic parts. Some of these are: gasoline,
carbon tetrachlo ride, chlo rinated cleaning
solvents, ammonia and house hold
detergents that contain ammonia.
