OPERATING THE IMPACT WRENCH
See Figures 6 - 7, page 11.
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 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 may 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 im-
pacting 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.
OPERATION
INSTALLING AND REMOVING SOCKETS
See Figure 4, page 10.
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 inaccurate 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.
MODE SELECTOR
See Figure 5, page 10.
Press the mode selector to cycle between Low (1) speed,
Medium (2) speed, High (3) speed, and Auto Mode (A).
Auto Mode offers protection from over-tightening fasteners.
It allows for greater control, reducing damage to fasteners
and work surfaces. If the tool is in Auto Mode and running
in the forward direction, it will automatically shut down once
it starts impacting. If the tool is in Auto Mode and running
in the reverse direction, it will automatically shut down after
impacting has completed.
The range of speeds available in each setting are:
Low (1) .......................................................0–1,200 RPM
Medium (2) .................................................0–2,000 RPM
High (3).......................................................0–2,800 RPM
Auto Mode (A) ............................................0–2,000 RPM
NOTICE:
Never change modes while the tool is running. Doing so
may result in serious damage to the tool.
