You can make an improvised dust collector by taping a folded piece of paper (or a file folder)
•
to a wall, to reduce the amount of dust when drilling in walls (Fig. 13).
A tennis ball cut in half can serve as a dust collector when drilling in ceilings (Fig. 13).
•
When drilling holes in tile, practice on a scrap piece to determine the best speed and
•
pressure. To prevent the drill bit from skidding/sliding, first apply two pieces of masking tape
to create an "X" shape over the intended drilling spot (Fig. 13). To prevent tile damage, do not
run the tool in hammer drilling setting
Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

Driving Screws (Fig. 14)
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 first. 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 difficult. 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 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 the screw.
g. To stop the drill/driver, release the trigger switch and allow the tool to come to a complete
stop.
