Speed Selection
Choose a low or high speed to suit
the use.
The more the speed control trigger is
pulled, the higher the speed becomes.
CAUTION:
Check the speed selector switch
before use.
Use at low speed when strong
force is needed during opera-
tion. (Using at high speed while a
strong force is applied may cause
a motor breakdown.)
Do not operate the speed selector
switch (LOW-HIGH) while pulling
on the speed control trigger. This
can cause the rechargeable bat-
tery to wear quickly or damage the
internal mechanism of the motor.

NOTE:
When the brake operates, a braking
sound may be heard. This sound
indicates engagement of the bit lock.
CAUTION:
To eliminate excessive tempera-
ture increase of the tool surface,
do not operate the tool continu-
ously using two or more battery
packs. Tool needs cool off time
before switching to another pack.
Do not close up vent holes on body
sides of the body during operation.
Otherwise, the machine function is
adversely affected to cause a failure.
Do NOT strain the tool (motor). This
may cause damage to the unit.
Use the machine in such a way as
to prevent the air from the body vent
holes from blowing directly onto your
skin. Otherwise, you may get burnt.
When operating with a Ni-MH bat-
tery pack, make sure the place is
well-ventilated.
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 confirm-
ing the tightness of a screw or to
loosen an extremely tight screw.
For Appropriate use of
Battery pack
Ni-MH Battery pack (EY9251)
Charge the Ni-MH battery fully before
storage in order to ensure a longer
service life.
The ambient temperature range is be-
tween 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 bat-
tery until charging is completed for
appropriate functioning of the battery.
When battery pack is not in use,
keep it away from other metal objects
like: paper clips, coins, keys, nails,
screws, or other small metal objects
that can make a connection from one
terminal to another.
Shorting the battery terminals togeth-
er may cause sparks, burns or a fire.
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 the 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
