When support arm can't be used:
When threading pipe in place or similar application, the
support arm may not be able to be used because of
space constraints.
a. If possible remove the pipe and thread in a vise. If
this cannot be done, other support devices must be
used to help resist threading forces, such as plac-
ing the power drive gear or fan housing against an
adjacent structural member (examples include
walls, beams and joists). This requires that the
pipe and surroundings be 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 elements.
b. For right hand threads, die head will rotate clock-
wise (looking at the face of the Die Head). Forces
developed by the threading torque will be in the
opposite or counter-clockwise direction. Rotation
and force will be reversed for left hand threads.
Make sure that the support device is set up to
properly absorb the threading force.

600-I/690-I Power Drives
c. Do not place the power drive motor or handle
against adjacent structural members to react
threading forces, as this may cause power drive
damage .
d. Keep power drive against the structural member
and do not place fingers or hands between the
power drive and the structural member. When
backing die head off thread, always firmly hold
the power drive to resist forces from breaking the
thread chips. These steps will reduce the risk of
striking, crushing and other injuries. The ON/OFF
switch can be released at any time to shut OFF the
power drive.
For pipe 1 / " diameter and smaller:
2
Pipe 1 / " and smaller nominal dimension can be
2
threaded without the use of a support device. In
this case, the operator resists the threading forces.
The pipe must be properly secured to prevent rota-
tion. Always firmly hold the power drive when thread-
ing or backing die head off pipe to resist forces,
regardless of support device use. This will reduce
the risk of striking, crushing and other injuries. The
ON/OFF switch can be released at any time to shut
off the power drive.

Threading

10. With dry hands, plug in the power drive.
11. Position the die head over the pipe end and sup-
port the power drive as directed in the Resisting
Threading Forces Section.
Figure 13 – Starting the Thread
12. Simultaneously actuate the ON/OFF switch and push
against the Die Head cover plate with the palm of free
hand to start the thread. Do not wear gloves, jewelry
or use a rag while pushing on the cover plate – this
increases the risk of entanglement and injury. Once
