A new battery will work properly after five
times of charging and discharging. Charge and
discharge the battery, which is not used for
a long time, for two to three times to function
well.
(3) When the battery working time is remarkably
short despite full charging, the life of the
battery may be over. Replace the battery
immediately.
Take care not to short-circuit the terminal
of the battery. The short-circuit of the
terminal may cause a fire or explosion
doing a serious personal injury.
2. Charging process
Use only the specified battery and battery charger.
Otherwise battery and charger can be damaged by
fire, explosion, charging error or overheat.
1) Charging indication
Green Blinks : Before charging
Red Lights : While charging
Green Lights : Charging completed
Red Blink : Overheat stand by
(Battery overheated)
Yellow Blinks : Charging impossible
Be sure to unplug the charger after
finishing the charging.
2) If charging of the heated battery is attempted
immediately after it has been used or charged,
indicator blinks in red (overheat stand by). After
the cooling, indication changes to red glowing
and charging begins.
3) This charger detects charging status of the
battery and always keeps the battery in full
charge state.
Use only the specified battery and battery
charger. Otherwise battery and charger can
be damaged by fire, explosion, charging
error or overheat.
3. Installing and removing battery
1) Installing.
• Set the rotational direction switch at centre
position (locked state).
• Insert the charged battery into the slot
below the handle until the battery securely
latched with a click.
2) Removing.
• Push the battery button once and take it
out to remove it.
Always set the rotational direction switch at
centre position when inserting the battery
or changing, carrying or storing the tool.
4. Charge state of the battery
Pulling the switch trigger will turn on the
battery level indicator for about 2 seconds.
1 = Battery 70 - 100% charged
2 = Battery 30 - 69% charged
3 = Battery less than 30% charged
4 = Battery flat of defective
(Blinking/Turn off)
5. Work light
Pulling the switch trigger will turn on
the LED light
6. Reversing the Rotation Direction
Reversing the rotation direction must be done
only when the tool is switched off. Reversing the
direction during operation may damage the tool
L (Left rotation) : Counter clockwise direction
(for loosening of screw)
R (right rotation) : Clockwise direction
(for fastening of screw, drilling)
Neutral : Rotation lock (for changing the bit)
7. Adjusting the Speed
1) Press the switch
The power tool switch allows the speed to be
increa
sed steeples up to maximum.
2) Move the speed selector switch
1: Low speed, high torque
2: High speed, low torque
Do not change direction of rotation until
the power tool is at a stand still.
8.
Torque setting
1) Screw work
• Selection is feasible from among five setting
anges by force (torque) adjustment ring.
Low setting range when working with small
screw or at soft working material.
High setting range when working with large
screw or at hard working material.
• When the tool is reached at the set torque,
the overload clutch begins to work to keep the
tool in the desired torque. You should set the
desired torque in the practical work.
