Red color lamp lights on.
Then, the lamp goes out.
NOTE:
• Use presetting number as a guideline. To
keep the fastening torque, number of impacts
changes automatically by remaining battery
capacity.
Indicating lamp
► 1. Indicating lamp
• After impacting preset numbers, the indicating
lamp lights in green color.
• The red color light will light on if the trigger is
released before the presetting number of impacts
is achieved. It indicates that the operation is
incomplete.
• When auto-stop mechanism is working, the indi-
cating lamp lights red while the switch trigger is
being pulled.
ASSEMBLY

• Always be sure that the tool is switched off and
the battery cartridge is removed before carrying

► 1. Sleeve 2. Bit
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will
go. Then release the sleeve to secure the bit.
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
NOTE:
• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and
the bit will not be secured. In this case, try re-insert-
ing the bit according to the instructions above.
OPERATION
[*1] Presetting number of impacts is impossible for more
than 200 impacts (4 seconds).
[*2] Fastening time includes when you pull the trigger
completely.
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between
fastening torque, fastening time and number of impacts
(presetting number) is shown in the figures.
Hold the tool firmly and place the point of the driver bit
in the screw head. Apply forward pressure to the tool to
the extent that the bit will not slip off the screw and turn
the tool on to start operation.
