cases, die heads/adapters may need to be rotated to
allow the pawl to engage. 770 and 773 adapters
must have the die head installed in the adapter prior
to insertion in the Power Drive.
3. To remove, squarely pull die head from power drive. If
needed, use a soft face hammer or a block of wood to
tap the die head out. Do not pound on the die head,
this can damage the tool.

Resisting Threading Forces
(Support devices)
For right hand threads, die head will rotate clockwise
(looking at the face of the Die Head). Forces developed by
the threading torque will be in the opposite or counter-clock-
wise direction. Rotation and force will be reversed for left
hand threads. Make sure that the support device is set up
to absorb and resist the threading force.
Using the No. 775 Support Arm:
1. Support arm yoke hook can be assembled to either
side. Securely tighten hinge bolt.
2. Position the support arm on pipe so end of support
arm aligns with end of pipe and 700 Power Drive
will be slightly above horizontal (Figure 5 and 6).
This properly places the support arm for threading and
prevents threading oil from running down power drive.
3. Make sure that the support arm jaws are squarely
aligned with the pipe and securely tighten the support
arm.

Using a RIDGID 12", 14" or 18" Heavy Duty Pipe
Wrench:
1. Securely install the torque arm into the fan housing of
the 700 Power Drive. A 5" (127 mm) long piece of ½"
schedule 80 steel pipe with a ½" NPT thread can also
be used.
2. Place the RIDGID 12", 14" or 18" Heavy Duty Pipe
Wrench approximately 7" (175 mm) from the end of
the pipe (see Figure 7). Test to confirm the wrench is
secure, and will not fall or move.
3. When starting the thread, the torque arm will sit on the
pipe wrench handle.
