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-

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.

CAUTION:

 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.

CAUTION:

 If the tool is operated continuously 

until the battery cartridge has discharged, allow the 

tool to rest for 15 minutes before proceeding with a 

fresh battery cartridge.

CAUTION:

 

Pressing excessively on the tool will 

not speed up the drilling.

 In fact, this excessive pressure 

will only serve to damage the tip of your drill bit, decrease 

the tool performance and shorten the service life of the tool.

CAUTION:

 

Always secure workpieces in a 

vise or similar hold-down device.

The proper fastening torque may differ depending upon 

the kind or size of the bolt, the material of the workpiece 

to be fastened, etc.
