Gear II
High speed range: for working with small drilling
diameter
WARNING: To prevent gear damage,
always allow the chuck to come to a
complete stop before changing the direction
of rotation or the two-speed gear control.
5. CHUCK ADJUSTMENT (SEE D)
To open the chuck jaws rotate the front section of
the chuck. Insert the drill bit between the chuck
jaws and rotate the front section in the opposite
direction. Ensure the drill bit is in the center of
the 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 E)
(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 - 15 for driving screws into soft and hard
material
For heavy drilling

7. AUTOMATIC SPINDLE LOCK (SEE F)
The automatic spindle lock allows you to use it
38
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
To turn on the light simply press the on/off switch.
When you release the on/off switch, the light will
be off.
LED lighting increases visibility-great for dark or
enclosed area. LED is also a battery capacity
indicator. It will flash when power gets low.
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
cutting. Do not force or apply side pressure to
elongate a hole.
Tungsten carbide drill bits should
always be used for concrete and
masonry. 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, apply a small quantity of liquid
soap or similar to the screw threads to ease
insertion.
