OPERATING INSTRUCTIONS
13. Screw Driving
Try to use standard-type screws for easy driving and
improved grip.
a. Install the correct driver bit.
b. Ensure that the torque-adjustment ring is set to
the most suitable setting. If in doubt, start with a
low setting and gradually increase the setting as
necessary. Do not change the torque setting when
the tool is running.
c. Use the correct speed range for the job and initially
apply minimal pressure to the variable-speed trigger
switch. Increase the speed only when full control can
be maintained.
d. It is advisable to drill a pilot hole rst. This hole
should be slightly longer than the screw to be driven
and just smaller than the shank diameter of the screw. The pilot hole will act as a guide for the
screw and will also make tightening the screw less difcult. When screws are positioned close
to an edge of the material, a pilot hole will also help to prevent splitting of the wood.
e. Use a countersinking bit (sold separately) to accommodate the screw head so that it does not
protrude from the surface.
f. Keep sufcient pressure on the drill to prevent the bit turning out of the screw head. The screw
head can easily become damaged, making it difcult to drive home or remove.
g. To stop the drill/driver, release the trigger switch and allow the tool to come to a complete stop.
