 NOTICE:

Never change speeds while the tool is running. 
Doing so may result in serious damage to the tool.

INSTALLING AND REMOVING SOCKETS

See Figure 5, page 8.

Use only sockets designed for impact wrenches. Always 
select the correct size impact socket for nuts and bolts.

CAUTION:

Using the wrong size socket may damage the nut 
or bolt and cause the fastening torque to be inac-
curate or inconsistent.



  Remove the battery pack.



  Push the socket onto the anvil until the friction ring locks 

it into place.



  To remove the socket, pull it away from the anvil.

NOTE: 

Sockets are not included with this tool.

OPERATING THE IMPACT WRENCH

See Figures 6 - 7, page 8.

CAUTION

:

The metal surface may become hot during use. 
Avoid contact with it to avoid possible burn injury.

Proper fastening torque may be determined by the kind of 
bolt, the size of the bolt or the material or the workpiece. It 
is helpful to perform a test operation to determine the proper 
fastening time for the nut or bolt you are using. 



  Hold the tool with one hand and pointed straight at the 

nut or bolt.



  Depress the switch and fasten for the proper fastening 

time.



  Remove the impact wrench from the nut or bolt.



  Check the torque with a torque wrench.

 NOTICE:

Do not use this tool to install lug nuts on wheels 
without a torque limiting device. Doing so could 
result in galled or broken lugs.

IMPACT TIME

Many variables exist that will cause the maximum torque 
to the fastener to vary considerably, including the size and 
threading of the fastener, lubrication, material hardness, and 
environmental conditions. 

NOTE:

 Using a universal joint or extension bar may reduce 

the fastening force of the impact wrench and require longer 
fastening time.

 NOTICE:

After the head of a nut or bolt has seated, 
 additional impacting will increase the chance of 
shearing bolts, nuts, sockets or tearing into wood.

ELECTRIC BRAKE

The electric brake will stop the socket rotation after the 
operator releases the switch trigger.
