Lighting up the front lamp
Fig.4
CAUTION:
Do not look in the light or see the source of light directly.
•
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The light automatically goes out 10 - 15 seconds after
the switch trigger is released.
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.
Reversing switch action
Fig.5
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 counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
CAUTION:
Always check the direction of rotation before operation.
•
Use the reversing switch only after the tool comes
•
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
When not operating the tool, always set the
•
reversing switch lever to the neutral position.
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.6
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.7
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.
Hook
Fig.8
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.9
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.
