CAUTION:
Do not operate Forward/Reverse lever until the chuck comes to a com- plete stop. Shifting during rotation of the chuck may damage the tool.
Forward Rotation Switch Operation
1.Push the lever for forward rotation.
2.Depress the trigger switch slightly to start the tool slowly.
3.The speed increases with the amount of depression of the trigger for efficient tightening of screws and drilling. The brake operates and the chuck stops im- mediately when the trigger is released.
4.After use, set the lever to its center position (switch lock).
Reverse Rotation Switch Operation
1.Push the lever for reverse rotation. Check the direction of rotation before use.
2.Depress the trigger switch slightly to start the tool slowly.
3.After use, set the lever to its center position (switch lock).
Clutch Torque Setting
Adjust the torque to one of the 15 possible settings or “ 
“ position to the job.
CAUTION:
Test the setting before actual operation. Set the scale at this mark ( 
).
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
*See appendix for “RECOM -
MENDED SPEED SELECTION”.
NOTE:
When the brake operates, a brak- ing 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
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 
f-cm,
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 (posi- tion 
on the clutch), for confirming the tightness of a screw or to loosen an extremely tight screw.
