Bit-locking function
1. With the trigger switch not engaged
and a screwdriver bit locked in
place, the tool can be used as a
manual screwdriver (up to 22.6 Nm,
230 k f-cm, 199 in-lbs).
There will be a little play in the
chuck, but this is not a malfunction.
2. This feature is handy for tightening
screws that require more torque
than the maximum torque of the
driver (position on the clutch), for
confirming the tightness of a screw
or to loosen an extremely tight
screw.
Speed Selection

For Appropriate use of Battery
pack
Ni-MH Battery pack EY9231
Charge the Ni-MH battery fully be-
fore storage in order to ensure a
longer service life.
The ambient temperature range is
between 0°C (32°F) and 40°C
(104°F).
If the battery pack is used when the
battery temperature is below 0°C
(32°F) the tool may fail to function
properly. In that case, charge the
battery until charging is completed
for appropriate functioning of the
battery.
When operating with a Ni-MH bat-
tery pack, make sure the place is
well-ventilated.
Battery Pack Life
The rechargeable batteries have a
limited life. If operation time becomes
extremely short after recharging,
replace the battery pack with a new
one.
Note:
Use under extremely hot or
cold conditions will reduce
operating capacity per charge.
Charging
Note:
When you charge the battery
pack for the first time, or after
prolonged storage, charge it
for about 24 hours to bring the
batteries up to full capacity.

1. Plug the charger into the AC outlet.
Note:
Sparks may be produced
when the plug is inserted into
the AC power supply, but this
is not a problem in terms of
safety.
2. Insert the battery pack firmly into
the charger.
