RIDGID R872081 Operator's Manual page 6

OPERATION
INSTALLING/REMOVING BATTERY PACK
See Figure 3, page 8 (R872071).
See Figure 3, page 9 (R872081).
 Lock the switch trigger.
 Insert the battery pack into the product as shown.
 Make sure the latches on each side of the battery pack
snap into place and that battery pack is secured in the
product before beginning operation.
 Depress the latches to remove the battery pack.
For complete charging instructions, see the operator's manu-
als for your battery pack and charger.
INSTALLING AND REMOVING SOCKETS
See Figure 4, page 8 (R872071).
See Figure 4, page 9 (R872081).
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.
TRI-BEAM LED LIGHTS
See Figure 5, page 8 (R872071).
See Figure 5, page 9 (R872081).
The tri-beam LED lights around the anvil illuminate when the
switch trigger is depressed.
If the tool is not in use, the time-out feature will cause the
light to start fading and then shut off.
The tri-beam LED lights illuminate only when there is a
charged battery pack in the tool.
MODE SELECTOR
See Figure 5, page 8 (R872071).
See Figure 5, page 9 (R872081).
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) ..........................................................0-850 RPM
 Medium (2) .................................................0-2,100 RPM
 High (3).......................................................0-2,800 RPM
 Auto Mode (A) ............................................0-2,800 RPM
NOTICE:
Never change modes while the tool is running.
Doing so may result in serious damage to the tool.
OPERATING THE IMPACT WRENCH
See Figures 6 - 7, page 8 (R872071).
See Figures 6 - 7, page 9 (R872081).
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.
