Full speed mode
► Fig.9: 1. Button
When full speed mode is turned on, the tool speed becomes
fastest even if you do not pull the switch trigger fully. When
full speed mode is turned off, the tool speed increases as
you increase the pressure on the switch trigger.
To turn on full speed mode, press and hold the button
turn off full speed mode, press and hold the button
The lamp turns on while full speed mode is on.
NOTE: Full speed mode continues even after switch-
ing the impact force mode/auto stop mode.
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.
Selecting correct impact socket
Always use the correct size impact socket for bolts and nuts.
An incorrect size impact socket will result in inaccurate and
inconsistent fastening torque and/or damage to the bolt or nut.
Installing or removing impact socket
CAUTION:
Make sure that the impact socket
and the mounting portion are not damaged before
installing the impact socket.
CAUTION:
After inserting the impact socket,
make sure that it is firmly secured. If it comes out,
do not use it.
For impact socket with O-ring and pin
► Fig.10: 1. Impact socket 2. O-ring 3. Pin
Move the O-ring out of the groove in the impact socket
and remove the pin from the impact socket. Fit the impact
socket onto the square drive so that the hole in the impact
socket is aligned with the hole in the square drive.
Insert the pin through the hole in the impact socket and
square drive. Then return the O-ring to the original posi-
tion in the impact socket groove to retain the pin.
To remove the impact socket, follow the installation
procedures in reverse.
Installing hook
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
► Fig.11: 1. Groove 2. Hook 3. Screw
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool. To install
the hook, insert it into a groove in the tool housing
on either side and then secure it with two screws. To
remove, loosen the screws and then take it out.

OPERATION
CAUTION:
all the way until it locks in place. If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
► Fig.13
Hold the tool firmly and place the impact socket over
the bolt or nut. Turn the tool on and fasten for the proper
fastening time.
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
