Lithium-Ion Cordless Drill/Driver EN
higher speed and torque with increased
trigger pressure. Speed is controlled by the
amount of switch trigger depression.
WARNING: Do not operate for long
periods at low speed because
excess heat will be produced internally.
2. SWITCH LOCK
The switch trigger can be locked in the OFF
position. This helps to reduce the possibility of
accidental starting when not in use. To lock the
switch trigger, place the rotation control in the
center position.
3. REVERSIBLE (See Fig. C1, C2)
For drilling and screw driving use forward
rotation marked “
” (lever is moved to the
left). Only use reverse rotation marked “ ”
(lever is moved to the right) to remove screws
or release a jammed drill bit.
WARNING: Never change the
direction of rotation when the
chuck is rotating, wait until it has
stopped!
4. TWO-SPEED GEAR CONTROL
(See Fig. D)
The drill has a two-speed gear control
designed for drilling or driving at LO (mark is
1) or HI (mark is 2) speeds. A slide switch is
located on top of the drill to select either LO
or HI speed. When using the drill in the LO
speed range, the speed will decrease and the
drill will have 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.
5. CHUCK ADJUSTMENT (See Fig. E)
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. F)
(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. G)
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 SIGHT LIGHT
To turn on the light, press the on/off switch
and make sure the forward/reverse rotation
control is on right/left position. 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
