Set the scale at this mark ( ). Speed Selection Choose a low or high speed to suit the use. LOW HIGH The more the variable speed control trigger is pulled, the higher the speed becomes. CAUTION: Check the speed selector switch before use. Use at low speed when high torque is needed dur­ing operation. (Using at high speed when high torque is required 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 battery to wear quickly or damage the inter­nal mechanism of the motor. * See specifications for "RECOM­ MEND­ED CAPACITIES". NOTE: When the brake operates, a braking sound may be heard. This sound indicates engagement of the bit lock. CAUTION: To prevent excessive tempera­ture increase of the tool surface, do not operate the tool continu­ously using two or more battery packs. The tool needs cool-off time before switching to another pack. Do not close up vent holes on the 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 tool in such a way as to prevent the air from the body vent holes from blowing directly onto your skin. Otherwise, you may get burned. 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 N·m, 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. How to Use the Belt Hook WARNING! • Be sure to attach the belt hook se­ cure­ly to the main unit with the screw firmly fastened. When the belt hook is not firmly attached to the main unit, the hook may disconnect and the main unit may fall. This may result in an accident or injury. • Periodically check screw for tightness. If found to be loose, tighten firmly. • Be sure to attach the belt hook firmly and securely onto a waist belt or other belt. Pay attention that the unit does not slip off the belt. This may result in an accident or injury. • When the main unit is held by the belt hook, avoid jumping or running with it. Doing so may cause the hook to slip and the main unit may fall. This may result in an accident or injury. -  -

CAUTION:
Check the speed selector switch
before use.
Use at low speed when high
torque is needed during operation.
(Using at high speed when high
torque is required 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 specifications for “RECOM-
MENDED CAPACITIES”.
NOTE:
When the brake operates, a braking
sound may be heard.
This sound
indicates engagement of the bit lock.

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 ±±.6
N·m, ±30 k
f-cm, 199 in-lbs).
There will be a little play in the
chuck, but this is not a malfunction.
±. This feature is handy for tightening
screws that require more torque than
the maximum torque of the driver

How to Use the Belt Hook
WARNING!
• Be sure to attach the belt hook se-
curely to the main unit with the screw
firmly fastened. When the belt hook
is not firmly attached to the main unit,
the hook may disconnect and the

This may result in an accident or
injury.
• Periodically check screw for tightness.
If found to be loose, tighten firmly.
•
Be sure to attach the belt hook firmly
and securely onto a waist belt or other
belt. Pay attention that the unit does not
slip off the belt.
This may result in an
accident or injury.
• When the main unit is held by the
belt hook, avoid jumping or running
with it.
Doing so may cause the hook
