• Depress and hold the switch. Inspect the moving
parts for misalignment, binding, odd noises or any
other unusual conditions that may affect the safe
and normal operation of the tool. If such condi-
tions are present, have the Power Drive serviced.
• Depress switch in the opposite direction. Check
that the Power Drive rotates in the opposite direction.
Operating Instructions
For Threading With Drop Head
Die Heads
WARNING
Do not wear gloves or loose clothing when oper-
ating Power Drive. Keep sleeves and jackets but-
toned.
Do not use this Power Drive if the switch is bro-
ken. Always wear eye protection to protect eyes
from dirt and other foreign objects.
When threading pipe one inch or larger, use the
No. 775 Support Arm or other mechanical means
to resist high handle force developed during
threading.
1. Push Die Heads or Adapters, spline end first, square-
ly into the Power Drive until the spring-loaded adapter
pawls catch securely (Figure 3).
NOTE! Installation can be made into either side of the
Power Drive.

2. If possible, secure the pipe in a portable tristand vise
or a bench vise.
To prevent tipping, long lengths of pipe
should also be supported with pipe stand.
3. Be sure the 418 Oiler is properly filled with RIDGID
Thread Cutting Oil. Position the oiler in front of the vise
(Figure 4).
4. Position No. 775 Support Arm on pipe so end of
tang is in line with end of the pipe (Figures 4 & 5).
Make sure jaws squarely contact pipe and tighten
handle firmly to prevent the slipping of the jaws.
To avoid serious injury from losing control
of the Power Drive, a support arm should be used when
threading one inch or larger pipe.
If the No. 775 Support Arm is not available or cannot be
properly attached to the pipe, a pipe wrench may be used
by securing the wrench to the pipe and contacting the
Power Drive’s auxiliary handle (Figure 6). Position wrench
a sufficient distance from the Power Drive to allow for
the desired length of thread to be cut.
When threading pipe less than one inch in size without a
support arm, hold onto the Power Drive firmly with one
hand to exert pressure against the handle forces devel-
oped during threading.
