7. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig. 11)
When releasing your finger from the remaining
battery indicator switch, the remaining battery
indicator lamp goes off. The Table 4 shows the state
of remaining battery indicator lamp and the battery
remaining power.
State of lamp
Battery Remaining Power
The battery remaining power
is enough.
The battery remaining power
is a half.
The battery remaining power
is nearly empty.
Re-charge the battery soonest
possible.
As the remaining battery indicator shows somewhat
differently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE:
Do not give a strong shock to the switch panel or
break it.It may lead to a trouble.
To save the battery power consumption, the
remaining battery indicator lamp lights while pressing
the remaining battery indicator switch.
8. How to use the LED light
Every time you press the light switch on the switch
panel, the LED light lights or goes off. (Fig. 12)
To prevent the battery power consumption, turn off
the LED light frequently.
CAUTION:
Do not expose directly your eye to the light by looking
into the light.
If your eye is continuously exposed to the light, your
eye will be hurt.
NOTE:
To prevent the battery power consumption caused
by forgetting to turn off the LED light, the light goes
off automatically in about 15 minutes.
OPERATIONAL CAUTIONS
1. Resting the unit after continuous work
(1) After use for continuous screw-tightening work, rest
the unit for 15 minutes or so when replacing the
battery. The temperature of the motor, switch, etc.,
will rise if the work is started again immediately after
battery replacement, eventually resulting in burnout.
NOTE:
Do not touch the protector, as it gets very hot during
continuous work.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently,
11
Table 4
when the switch trigger is pulled only slightly (low
speed rotation) and the motor is stopped while
continuously driving in screws, the components of
the electronic circuit parts may overheat and be
damaged.
3. Screw sizes and tightening times
Refer to the following diagram below which indicates
screw sizes and tightening times.
Use these tightening times as a preliminary estimate,
since they may vary due to the hardness of the wood,
ambient temperatures and the properties of the
rechargeable batteries, etc.
Wood screws
(with cutting edges)
4mm x 50
Wood screws
(with cutting edges)
4.2mm x 75
Wood screws

NOTE:
The sizes of the screws which can be tightened will
vary according to the wood. Therefore, test-tighten a
few screws before doing the actual tightening to
verify whether or not they can be tightened.
NOTE:
If a long striking time is used, screws will be strongly
tightened. This may cause the screw to break, or may
damage the tip of the bit.
If the unit is held at an angle to the screw being
tightened, the head of the screw may be damaged, or
the specified torque may not be transmitted to the
screw. Always keep the unit and the screw being
tightened in a straight line.
4. Use bits which match the screw's diameter
Be careful to not damage the heads of the screws by
using bits which do not match the screw's diameter.
5. Holding the tool
Hold the oil pulse driver firmly with both hands. In
this case hold the driver in line with the screw.
It is not necessary to push the driver very hard. Hold
the driver with a force just sufficient to counteract the
pulse force.
FEATURES OF THE CORDLESS OIL PULSE
DRIVER
The oil pulse driver is a hydraulic impact driver that
uses oil viscosity to generate pressure for the
tightening of screws. Due to the usage of this method,
the noise that is generated when screws are being
tightened has been greatly reduced in comparison to
that of other impact drivers. In contrast though, the
inherent reverberations of the oil pulse are greater in
comparison to those of impact drivers, so firmly
steady the tool.
NOTE:
Since the viscosity of the oil will vary according to
the temperature, pay heed to the following points in
using the tool.
