chuck jaws. Finally, firmly rotate the front chuck
section in the opposite directions. Your drill bit is
now clamped in the chuck.
6. TORQUE ADJUSTMENT (SEE Fig I)
(Screw driving force of your drill driver)
The torque is adjusted by rotating the torque
adjustment ring. The torque is greater when the
torque adjustment ring is set on a higher setting.
The torque is less when the torque adjustment ring
is set on a lower setting.
Make the setting as follows:
1 - 4 for driving small screws
5 - 9 for driving screws into soft material
10 - 18 for driving screws into soft and hard
material
for heavy drilling
7. AUTOMATIC SPINDLE LOCK (SEE Fig J)
The automatic spindle lock allows you to use it as
a regular screwdriver. You can give an extra twist
to firmly tighten a screw, loosen a very tight screw
or continue working when the battery energy has
expired. For manual screwdriver purposes, the
chuck is automatically locked when the tool is off.
8. USING THE LED LIGHT (SEE Fig K)
The LED light(b) allows you to keep a clear view
under less illuminated circumstances. To turn on
the light simply press the on/off switch. When you
release the on/off switch, the light will go out.
9. DRILLING
When drilling into a hard smooth surface, use a
center punch to mark the desired hole location.
This will prevent the drill bit from slipping off center
as the hole is started. Hold the tool firmly and place
the tip of the bit at the point to be drilled. Depress
the switch trigger to start the tool. Move the drill bit
into the workpiece, applying only enough pressure
to keep the bit rotating. Do not force or apply side
pressure to elongate a hole.
When drilling in metal, only use HSS
drill bits in good condition. Always use a
magnetic bit holder (not included) when using
short screwdriver bits. When screw-driving,
