Figure 8 – Threading with Hand Threader
7. Depress and hold down the foot switch.
8. Push the die head against the pipe using the palm of
the right hand until the dies engage the workpiece.
Once engaged, the threads will be cut as the dies
pull themselves onto the end of the pipe (Figure 7) .
9. Remove the right hand from the area of the die head
and liberally oil the dies while the pipe is threaded
(Figure 8).
To avoid serious injury from rotating parts,
allow adequate clearance between your hand and the
rotating parts while oiling.
10. Release the foot switch and remove your foot from the
housing when the pipe reaches the end of the dies.
11. Lift the threader handle slightly with the right hand
while sliding the left support bar all the way toward the
rear of the drive.

a firm grip on the threader as the threader will drop to the
floor if not supported when unthreaded completely.
17. Release the foot switch and remove your foot from
the housing.
18. Set the threader down and, if necessary, wipe oil
and debris off the threads with a rag, taking care not to
cut your hand or fingers on any sharp debris or edges.
19. Check the thread for length and depth
(Figure 14).
Removing Pipe from the Power Drive
1. Flip the directional switch to OFF.
2. Use repeated and forceful clockwise spins of the
speed chuck handwheel at the front of the Power
Drive to release the workpiece from the speed
chuck jaws.
3. If necessary, loosen the rear centering device using
a clockwise rotation of the handwheel at the rear of
the Power Drive.
4. Slide the workpiece out of the Power Drive, keeping
a firm grip on the workpiece as it clears the Power
Drive.
To avoid injury from falling parts or equip-
ment tip-overs when handling long workpieces, make
sure that the end farthest from the Power Drive is sup-
ported prior to removal.
5. Clean up any oil spills or splatter on the ground
surrounding the Power Drive.
