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.

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

007521
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 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.
