NOTE: To confirm the lamp status, pull the trigger.
When the lamp lights up by pulling the switch trigger,
the lamp status is ON. When the lamp does not come
on, the lamp status is OFF.
NOTE: When the tool is overheated, the light flashes
for one minute, and then the LED display goes off. In
this case, cool down the tool before operating again.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Changing the impact force
► Fig.8: 1. Hard 2. Soft 3. A mode 4. Changed in three
steps 5. Button
You can change the impact force in three steps: hard,
soft, and A mode.
This allows a tightening suitable to the work.
Every time the button is pressed, the number of blows
changes in three steps.

A mode
NOTE: A mode is available only when the tool rotates clockwise. When rotating counterclockwise in A mode, the
impact force and speed are the same as hard mode.
NOTE: When all lamps on the switch panel go out, the tool is turned off to save the battery power. The impact force
grade can be checked by pulling the switch trigger to the extent that the tool does not operate.
NOTE: While pulling the switch trigger, the impact force grade cannot be changed.
Maximum blows
-1
3,900 min (/min) Tightening when force and
speed are desired.
-1
1,600 min (/min) Tightening with less force to
avoid screw thread breakage.
-1
3,900 min (/min) Tightening screws with better
control.

Reversing switch action
► Fig.7: 1. Reversing switch lever
CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.
CAUTION:
When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
"A mode (assist mode)" is an easy-to-use mode for
driving screws with good control.
In this mode, the tool drives a screw with low-speed
rotation at first. After the tool starts to impact, the rota-
tion speed increases and reaches the maximum speed.
For approximately one minute after releasing the switch
trigger, the impact force can be changed.
Purpose Example of application
Tightening wood screws,
tightening bolts.
Tightening sash screws, tight-
ening small screws such as M6.
Tightening long screws.
