CAUTION
If the battery is heated due to direct sunlight,
etc., just after operation, the charger pilot lamp
may not light up. At that time cool the battery
first, then start charging.
3. Disconnect the charger power cord from the

PRIOR TO OPERATION

1. Setting up and checking the work environment
Check if the work environment is suitable by follow-
ing the precautions.

HOW TO USE

CAUTION:
Before installing batteries, make sure that the
reversing switch is in neutral position. (See Fig. 4.)
1. Confirm the cap position (see Fig. 5)
The tightening power of this unit can be adjusted
according to the cap position, at which the cap is
set.
(1) For using the unit as a screw driver, set the cap
white line to one of the numerals "1" to "5" on
the outer frame.
(2) For use as a drill, set the white line at the drill mark
" " (see Fig. 5).

CAUTION
Set the cap white line at one of either the numerals

2. Tlightening power adjustment
(1) Tightening power
Tightening power 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 cap position according to the
screw diameter.
(2) Tightening power indication
Tightening power should be changed according to
the screw type and the materials to be tightened.
Guidance of the tightening power is indicated on
the outer frame of this unit with numerals "1", "2",
"3", "4" and "5". The minimum power is from "1"
position and bigger numerals are stronger power
than smaller numerals (see Fig. 5).
(3) How to adjust the tightening power
Rotate the cap and set to one of the numerals.
Adjust the power by cap rotation in such a way that
when the power is too strong, set to the next
smaller numeral and set to the next larger numeral
when too weak.
CAUTION
The motor rotation may be locked to cease while
the unit is used as a drill. While operating the driver
drill, take care not to lock the motor.
Too long hammering may cause the screw broken
due to excessive tightening force.
3. Change rotation speed
Operate the shift knob to change the rotation speed.
Move the shift knob in the direction of the arrow
(see Figs. 6 and 7).
When the shift knob is set to "L", the drill rotates
at a low speed. When set to "H", the drill rotates
at a high speed.
CAUTION
When changing the rotation speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
When setting the shift knob to "H" (high speed) and
the position of the cap is "4" or "5", it may happen
that the clutch does not engaged and that the motor
is locked. In suh a case, please set the shift knob
to "L" (low speed).
If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor
or battery may be burnt out.
