OPERATING INSTRUCTIONS
12. Drilling
WARNING
• Always wear safety goggles or safety glasses
with side shields during power tool operation or
when blowing dust. If operation is dusty, also
wear a dust mask.
a. Set the direction-of-rotation selector (D) to
forward rotation.
b. Secure the material to be drilled in a vise or
with clamps to keep it from turning as the drill
bit rotates.
c. Hold the drill/driver firmly and place the bit at
the point to be drilled.
d. Depress the variable-speed trigger switch (E) to start the drill/driver.
e. Move the drill bit into the work piece, applying only enough pressure to keep the bit drilling.
Do not force the drill/driver or apply side pressure to elongate a hole. Let the tool do the
work.
f.
When drilling hard, smooth surfaces, use a center punch (sold separately) to mark the
desired location of the hole. This will prevent the drill bit from slipping off center as the hole
is started.
g. If the bit jams in the work piece or if the drill/driver stalls, stop the tool immediately.
Remove the bit from the work piece and determine the reason for jamming.
h. To stop the drill/driver, release the variable speed trigger switch and allow the tool to come
to a complete stop.
Drilling Wood
a. For maximum performance, use high-speed
steel or brad-point bits for drilling wood.
b. Begin drilling at a very low speed to prevent the
bit from slipping off the starting point.
c. Increase speed as the drill bit bites into the
material.
d. When drilling "through" holes, place a block of
wood behind the work piece to prevent ragged
or splintered edges on the back side of the
hole.
NOTICE: When drilling deep holes, the bit may
overheat. Change the direction of rotation and pull
out the bit frequently to clear wood chips from flutes.
