OPERATING INSTRUCTIONS
d. Depress the variable-speed trigger switch (E) to start the right angle drill/driver.
e. Move the drill bit into the workpiece, applying only enough pressure to keep the bit drilling.
Do not force the right angle 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 (not included) 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 right angle drill/driver stalls, stop the tool
immediately. Remove the bit from the workpiece and determine the reason for jamming.
h. To stop the right angle drill/driver, release the variable-speed trigger switch and allow the
tool to come to a complete stop.
Drilling in 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 workpiece to prevent
ragged or splintered edges on the back side of the hole.
Drilling in Metal
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 right angle drill/driver.
– Wear the bearings.
– Bend or burn bits.
– Produce off-center or irregular-shaped holes.
10. Screw Driving
a. Try to use modern screws for easy driving and improved grip.
b. 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.
c. Set the torque button (G) to the most suitable setting. If in doubt, start with a low setting,
then turn off the tool and increase the setting as needed.
NOTICE: Do not change the torque setting when the tool is running.
d. 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 it home or
remove it.
