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 operation.
(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.

See appendix for "RECOMMENDED
SPEED SELECTION”.
NOTE:
When the brake operates, a
braking sound may be heard.
This sound indicates engagement
of the bit lock.
CAUTION:
To eliminate excessive temperature
increase of the tool surface, do
not operate the tool continuously
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 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 bat-
tery.
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 operation time becomes
extremely short after recharging, replace
the battery pack with a new one.
