OPERATION

Driving operation
Fig.14
Switch on the tool by pulling the switch trigger. Hold the
tool squarely and firmly up against the driving surface. A
screw will be automatically carried to the driving position
and fastened.
CAUTION:
Always check the bit carefully for wear before
•
driving operations. Replace a worn bit or poor
fastening may result.
Always hold the tool squarely against the driving
•
surface. Holding it at an angle may damage the
screw heads and cause wear on the bit. This may
also lead to poor fastening.
Always keep the tool firmly against the driving
•
surface until the driving is over. Failure to do so
may cause insufficient fastening of screws.
Be careful not to drive a screw onto another screw
•
already fastened.
Do not operate the tool without screws. It will
•
damage the driving surface.
Do not apply oil or grease on the sliding surface of
•
the feeder box.
Driving in corner
Fig.15
This tool can be used to drive at a position 15 mm away
from the wall as shown in the figure.
CAUTION:
Driving at a position closer than 15 mm to the
•
wall or driving with the stopper base in contact with
the wall may damage the screw heads and cause
wear on the bit. This may also lead to poor
fastening of screws and malfunction of the tool.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Replacing carbon brushes

out the casing in the direction of the arrow.
