Depress the stopper base as far as it will go. While
keeping it in this position, turn the adjusting knob until
the bit tip projects approx. 5 mm from the stopper base.
Drive a trial screw. If the screw head projects above the
surface of the workpiece, turn the adjusting knob in the
"A" direction; if the screw head is counter-sunk, turn the
adjusting knob in the "B" direction.
Installing screw strip
Insert the screw strip through the screw guide. Then
insert it through the feeder box until the first screw
reaches the position next to the driving position.

MAINTENANCE

CAUTION:
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.
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.
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
