OPERATING INSTRUCTIONS
14. Driving Screws
Try to use standard-type screws for easy driving
and improved grip.
a. Install the correct driver bit.
b. Set the mode selector (C) to driving mode
for best performance.
c. 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.
d. 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.
e. It is advisable to drill a pilot hole first. This hole should be slightly longer than the screw
to be driven and slightly thinner 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 difficult. When
screws are positioned close to an edge of the material, a pilot hole will also help to prevent
splitting of the wood.
f. Use a countersinking bit (sold separately) to accommodate the screw head so that it does
not protrude from the surface.
g. Keep sufficient pressure on the drill to prevent the bit from turning out of the screw head.
The screw head can easily become damaged, making it difficult to drive home or remove.
h. To stop the hammer drill, release the trigger switch and allow the tool to come to a
complete stop.
