700 Power Drive
Other Support Methods:
Place the power drive motor housing (see Figure 1) a gainst
an adjacent structural member (examples include walls,
beams and joists). This requires that the pipe being thread-
ed and surroundings are able to withstand the weight of the
tool and the threading forces. It may be necessary to add
temporary or permanent pipe supports or structural ele-
ments to properly resist threading forces.
For pipe ¾" diameter and smaller:
Pipe ¾" and smaller nominal dimension can be threaded
without the use of support device. In this case, the operator
resists the threading forces. The pipe must be properly
secured to prevent rotation. Always firmly hold the power
drive when threading or backing die head off pipe to resist
forces. This will reduce the risk of striking, crushing and
other injuries.
Threading
1. With dry hands, plug in the power drive.
2. Position the die head over the pipe end and support
the power drive as directed in the Resisting Threading
Forces Section. Always keep the power drive against
the support device. Do not put anything between the
power drive and the support device – this increases
the risk of pinching and crushing injuries.
3. Assume a proper operating position to help maintain
control of the machine (See Figure 9),
• Be sure you have good balance and do not have to
overreach.
• Be sure you can control the switch button and
machine. Do not depress switch yet. In case of
emergency you must be able to release switch.
Figure 8 – Starting the Thread
4. Simultaneously actuate the switch button (see Figure
3) and push against the die head cover plate with the
8
palm of free hand to start the thread (Figure 8). Do not
wear gloves, jewelry or use a rag while pushing on the
cover plate – this increases the risk of entanglement
and injury. Once the dies engage the pipe, threads will
be cut as the dies pull themselves onto the end of
the pipe.
Always firmly hold the power drive handle to resist
the handle forces. Support devices can slip and allow
the power drive to move. The switch button can be
released at any time to shut OFF the power drive.

5. Stop pushing on cover plate and use oiler to apply a
generous quantity of RIDGID Thread Cutting Oil to the
area being threaded. This will lower threading torque,
improve thread quality and increase die life.
6. Keep switch depressed until end of the pipe is even
with edge of the dies (Figure 10). Watch to make
sure Power Drive does not run into the support
device. Release the switch button. Let the power
drive come to a complete stop.
