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. 9)
When releasing your fi nger 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
As the remaining battery indicator shows somewhat diff erently 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.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
After use for continuous bolt-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 hammer case, as they get 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, 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. Use a tightening time suitable for the screw
The appropriate torque for a screw diff ers according to the material and size of the screw,
and the material being screwed etc., so please use a tightening time suitable for the screw.
In particular, if a long tightening time is used in the case of screws smaller than M8, there
is a danger of the screw breaking, so please confi rm the tightening time and the tightening
torque beforehand.
Table 4
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.
