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. 6).
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.
WARNING
personnel may result in misplacing of
internal wires and components which
could
recommend that all tool service be performed
by a Bosch Factory Service Center or Autho-
rized Bosch Service Station.
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.
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.
