OPERATING INSTRUCTIONS
d. Depress the variable-speed trigger switch to start the drill/driver.
e. Move the drill bit (not included) into the workpiece, 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 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 workpiece or if the drill/driver stalls, stop the tool immediately. Remove
the bit from the workpiece and determine and correct 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.
Wood Drilling
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 workpiece to prevent
ragged or splintered edges on the back side of the hole.
Metal Drilling
a. For maximum performance, use high-speed steel bits for drilling metal or steel.
b. When drilling metals, use light oil on the drill bit to keep it from overheating. The oil will
prolong the life of the bit and increase the drilling action.
c. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
d. Maintain a speed and pressure which will allow cutting without overheating the bit.
Applying too much pressure will:
– Overheat the drill/driver.
– Wear the bearings.
– Bend or burn bits.
– Produce off-center or irregularly-shaped holes.
12. Screw Driving
a. Try to use modern screws for easy driving and improved grip.
b. Set the torque-adjustment to the most suitable setting. If in doubt, start with a low setting
and gradually increase the setting until the most. Do not change the torque setting when
the tool is running.
c. It is advisable to drill a pilot hole first. The pilot hole will act as a guide for the screw and
will also make tightening the screw less difficult.
d. Keep sufficient pressure on the drill to prevent the bit turning out of the screw head. The
screw head can easily become damaged, making it difficult to drive it home or remove it.
