WARNING:

 Use only impact sockets 

and accessories that are designed for use 
with an impact wrench.

 Do not use chrome 

plated sockets and accessories. Chrome plated 
sockets and accessories are designed for hand 
use only and MUST NOT be used with an 
impact wrench. They may shatter and possibly 
cause serious injury. 
 
       

WARNING:

 

Always remove the plug from 

the power source before changing any sockets 
or accessories. You may injure your hand if the 
tool is started accidentally. 
 
To install a socket, press the square portion of 
the socket (1) onto the square drive (2) of the 
impact wrench (Fig. 1). 
 

NOTE:

a car wheel, make sure all jacking, wheel 
blocking and wheel removal safety
