OPERATING INSTRUCTIONS
Drilling 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 efficiency.
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.
13. Driving Screws
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 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.
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.
g. To stop the drill/driver, release the trigger switch and allow the tool to come to a complete
stop.
