18V LI-ION IMPACT DRILL
WARNING: Do not operate for long periods
at low speed because excess heat will be
produced internally.
3. SWITCH LOCK(See Fig.C)
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 direction of Forward/Reverse rotating control
in the center position by pushing the direction buttons
on either side of the drill.
4. REVERSIBLE (See Fig. D1 & D2)
For drilling and screw driving use forward rotation
marked " " (lever is moved to the left). Only use
reverse rotation marked "
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.
5.TWO-SPEED GEAR CONTROL (See Fig. E)
The drill has a two-speed gear control designed for
drilling or driving at 1 or 2 speeds. A slide switch is
located on top of the drill to select either 1 or 2 speed.
When using the drill in the 1 speed range, the speed
will decrease and the drill will have greater power and
torque. When using the drill in the 2 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.
6. CHUCK ADJUSTMENT (See Fig. F)
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.

7. TORQUE ADJUSTMENT (See Fig. G)
(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 - 14 for driving screws into soft and hard material
15 - 20 for driving screws into hard wood
21 for driving larger screws
for heavy drilling
for drilling in masonry and concrete
8. AUTOMATIC SPINDLE LOCK (See Fig. H)
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.
9. USING THE SIGHT LIGHT
The sight light 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 be off.
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.
If you want to activate the drill function (For drilling
metal wood or plastic), turn the torque adjustment ring
on the drill position. If you want to activate the impact
function(For masonry or concrete), turn the torque
adjustment ring on the hammer position.
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-
