Changing the impact force
► Fig.7: 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.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.

"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.
You can change the impact force within approximately
one minute after releasing the switch trigger.
Purpose
Tightening when force and
speed are desired.
Tightening with less force to
avoid screw thread breakage.
Tightening screws with better
control.
Procedure 1
► Fig.9: 1. Driver bit 2. Sleeve
To install the driver bit, pull the sleeve in the direction of
the arrow and insert the driver bit into the sleeve as far
as it will go.
Then release the sleeve to secure the driver bit.
Procedure 2
In addition to Procedure 1, insert the bit-piece into the
sleeve with its pointed end facing in.
► Fig.10: 1. Driver bit 2. Bit-piece 3. Sleeve
To remove the driver bit, pull the sleeve in the direction
of the arrow and pull the driver bit out.
NOTE: If the driver bit is not inserted deep enough
into the sleeve, the sleeve will not return to its original
position and the driver bit will not be secured. In this
case, try re-inserting the bit according to the instruc-
tions above.
NOTE: When it is difficult to insert the driver bit, pull
the sleeve and insert it into the sleeve as far as it will
go.
NOTE: After inserting the driver bit, make sure that it
is firmly secured. If it comes out, do not use it.
