length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the
second hole the same diameter as the screw
shank in the first or top piece of wood.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank
clearance hole in the first piece allows the
screw head to pull the pieces tightly together.
DRIVING NUTS AND BOLTS
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attach ments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
Preventive maintenance performed by un -
au thorized personnel may result in
misplacing of internal wires and
components which could cause serious
hazard. We recom mend that all tool service
be performed by a Bosch Factory Service
Center or Authorized Bosch Service Station.
SERVICE MEN: Disconnect tool and/or
charger from power source before servicing.
BATTERIES
Be alert for battery packs that are nearing
their end of life. If you notice decreased
tool performance or significantly shorter
running time between charges then it is time
to replace the battery pack. Failure to do so
can cause the tool to operate improperly or
damage the charger.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready for use.
Maintenance
To avoid accidents, always disconnect the tool and/or charger from the
power supply before servicing or cleaning.

NO USER SERVICE-
ABLE PARTS INSIDE.
FASTENING WITH
SCREWS
1. Drill 2/3 diameter and
2/3 of screw length for
soft materials, full
length for hard
materials.
Apply a slight
even pressure
when driving
screws.
D.C. MOTORS
The motor in your tool has been engineered for
many hours of dependable service. To
maintain peak efficiency of the motor, we
recommend it be examined every six months.
Only a genuine Bosch replacement motor
specially designed for your tool should be used.
BEARINGS
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating and
motor failure.
Cleaning
Certain cleaning agents
and solvents damage
plastic parts. Some of these are: gasoline,
car bon tetrachloride, chlorinated cleaning
solvents, ammonia and household detergents
that contain ammonia.
Ventilation openings and switch levers must be
kept clean and free of foreign matter. Do not
attempt to clean by inserting pointed objects
through opening.
