Indicator lamps
Lighted Off
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Switch action (Fig. 3)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
• Change the direction of rotation only when the tool
comes to a complete stop. Changing it before the tool
stops may damage the tool.
The switch is reversible, providing either clockwise or
counterclockwise rotation. To start the tool, simply pull the
lower part (A) of the switch trigger for clockwise or the
upper part (B) for counterclockwise. Release the switch
trigger to stop.
Lighting up the front lamp (Fig. 4)
CAUTION:
• Do not look in the light or see the source of light
directly.
Push the upper position of the lamp switch for turning on
the light and the lower position for off.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
• The light is provided with anti excessive discharge
circuit. When the lamp does not light up even after the
light switch is turned on, there is likely to be battery
power drop. Try to charge the battery cartridge.
• Keep the lamp switch in "off" position while not in need
of the light.

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 socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and
inconsistent fastening torque and/or damage to the bolt or
nut.
Installing or removing socket (Fig. 5)
1. For socket without O-ring and pin
To install the socket, push it onto the anvil of the tool
until it locks into place.
To remove the socket, simply pull it off.
2. For socket with O-ring and pin (Fig. 6)
Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto the
anvil of the tool so that the hole in the socket is aligned
with the hole in the anvil. Insert the pin through the
hole in the socket and anvil.
Then return the O-ring to the original position in the
socket groove to retain the pin. To remove the socket,
follow the installation procedures in reverse.
Align the hole in the side of the socket with the detent pin
on the anvil and push it onto the anvil of the tool until it
locks into place. Tap it lightly if required.
To remove the socket, simply pull it off.
Hook
CAUTION:
After installing the hook, make sure that it is screwed
firmly. (Fig. 7)
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 a screw.
To remove, loosen the screw and then take it out.
OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. If you can see the red part on the upper
side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If not, it
may accidentally fall out of the tool, causing injury to
you or someone around you.
Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time. (Fig. 8)
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. (Fig. 9 & 10)
NOTE:
• Hold the tool pointed straight at the bolt or nut.
• Excessive fastening torque may damage the bolt/nut or
socket. Before starting your job, always perform a test
operation to determine the proper fastening time for
your bolt or nut.
