20V LI DRILL DRIVER

ENG

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

9. 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.

10. USING THE LED LIGHT

The LED light allows you to keep a clear view under less
illuminated circumstances. 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 go off.
The LED Light is also a battery capacity indicator. It will
ﬂash when power gets low.

11. 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.

12. DISPOSAL OF AN EXHAUSTED BATTERY PACK

To preserve natural resources, please recycle
or dispose of the Battery Pack (8) properly. This
Battery Pack contains Lithium batteries. Consult

your local waste authority for information regarding
available recycling and/or disposal options. Discharge
your Battery Pack by operating your drill, then remove
the Battery Pack from the drill housing and cover the

Battery Pack connections with heavy-duty adhesive tape
to prevent short circuit and energy discharge. Do not
attempt to open or remove any of the components.

TROUBLESHOOTING

1. WHY DOES THE DRILL NOT TURN ON WHEN YOU
PRESS THE SWITCH?

The Forward/Reverse Rotation Control (4), which is on top
of the trigger, is positioned in the lock function. Unlock
the Forward/Reverse Rotation Control by putting it into
the required rotation position. Push the trigger and the
drill will start to rotate.

2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?

Verify the torque position of the Torque Adjusting Ring.
You can ﬁnd the Torque Adjusting Ring between the
Chuck and the drill body. Position 1 is the lowest torque
(screw driving force) and position 15 is the highest
torque (screw driving force). Position 16 is for drill
operation. Regulate the Torque Adjusting Ring to a higher
position to reach the best result.

3. REASONS FOR DIFFERENT BATTERY PACK
WORKING TIMES

Not using a Battery Pack (8) for a prolonged time will
reduce the Battery Pack working time. This can be
corrected after several charge and discharge operations
by charging & working with your drill. Heavy working
conditions such as large screws into hard wood will use
up the Battery Pack energy faster than lighter working
conditions. Do not
re-charge your Battery Pack below 32° F (0°C) and
above 113° F (45°C) as this will affect performance.

MAINTENANCE

Your tool requires no additional lubrication or
maintenance.
There are no user serviceable parts in your power tool.
Never use water or chemical cleaners to clean your
power tool. Wipe clean with a dry cloth. Always store your
power tool in a dry place. Keep the motor ventilation slots
clean. Keep all working controls free of dust. Occasionally
you may see sparks through the ventilation slots. This is
normal and will not damage your power tool.
