CAUTION
If the battery is installed incorrectly, not
only the battery will not charge, but also
the battery charger may malfunction, for
example, compression terminals may
become deformed.
3. Charging. When the battery is connected
to the battery charger, charging will
commence and the pilot lamp will light
in red. When the battery is fully charged,
the green and red pilot lamps will light
simultaneously.
NOTE
Charging time may be longer depending
on the surrounding temperature and
battery conditions.
4. Unplug charger from receptacle.
5. Hold the charger firmly and remove the
battery.
How to make batteries perform longer.
1. Recharge the batteries before they
become completely exhausted. When you
feel that the power of the tool becomes
weaker, stop using the tool and recharge
its battery. If you continue to use the
tool and exhaust the electric current, the
battery may be damaged and its life will
become shorter.
2. Avoid recharging at high temperatures.
A rechargeable battery will be hot
immediately after use, its internal chemical
substance will deteriorate, and the battery
life will be shortened. Leave the battery
and recharge it after it has cooled for a
while.
CAUTION
If the battery is recharged when it is warm
due to battery use of exposure to sunlight,
the pilot lamp may light in green. In such a
case, let the battery cool before charging.
When the pilot lamp flickers rapidly in red,
check and take out any foreign objects in
the charger’s battery installation hole. If
there any foreign objects, it is probable that
the battery or charger is malfunctioning.
Take it to the authorized service center.
NOTE
Optimum temperature for use and storage
of the Li-ion battery is 5°C – 40°C. Regular
battery charging after a long period of use
and long period of storage will make the
battery to perform longer.
prior to operation
1. Check the area to make sure that it is
clear of debris and clutter.
Check whether working conditions meet
the safety measure.
2.Tightening torque adjustment
• Tightening torque should correspond in
its intensity to the screw diameter. When
too strong power is used, the screw head
may be broken or be injured. Be sure to
adjust the clutch dial position according to
the screw diameter.
• Tightening torque indication. The
tightening torque differs depending on
the type of screw and the material being
tightened. The unit indicates the tightening
torque with the numbers “1,4,7…16”
on the clutch dial, and black dots. The
tightening torque at position “1” is the
weakest and the torque is the strongest at
the highest number.
• Adjusting the tightening torque. Rotate
the clutch and line up the numbers
“1,4,7…16” on the clutch dial, or the dot,
with the triangle mark on the outer body.
Adjust the clutch dial in the weak or the
strongest torque direction according to the
