greater power and torque. When using the drill in the HI speed range,
the speed will increase and the drill will have less power and torque.
Gear I
Low speed range: for screwdriving or working with large drilling
diameter
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.

CHUCK ADJUSTMENT (See Fig. 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 Fig. 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 Fig. F)
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.

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 HOW TO USE THE HOOK (See Fig. G1, G2)
Screw the Hook on the tool with the screw provided in the plastic
bag. The Hook (6) can be hooked on your belt or pocket, etc.
10 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.
Warning: 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
