Lighting up the front lamp
Fig.3
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.4
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.5
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.6
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.7
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.
