1224 Threading Machine
Inspecting Threads
1. After removing the pipe from the machine, clean the
thread.
2. Visually inspect thread. Threads should be smooth
and complete, with good form. If issues such as
thread tearing, waviness, thin threads, or pipe out-of-
roundness are found, the thread may not seal. Refer
to the Troubleshooting Chart for help in diagnosing
these issues.
3. Inspect the size of the thread.
• The preferred method of checking thread size is
with a ring gauge. There are various styles of ring
gauges, and their usage may differ from that shown
here.
• Screw ring gauge onto the thread hand tight.
• Look at how far the pipe end extends through the
ring gage. The end of the pipe should be flush with
the side of the gauge plus or minus one turn. If
thread does not gauge properly, cut off the thread,
adjust the die head and cut another thread. Using a
thread that does not gauge properly can cause
leaks.

Figure 25 – Checking Thread Size
• If a ring gauge is not available to inspect thread
size, it is possible to use a new clean fitting repre-
sentative of those used on the job to gauge thread
size. For 2" and under NPT threads, the threads
should be cut to obtain 4 to 5 turns to hand tight
engagement with the fitting and for BSPT it should
be 3 turns. For 2 1 / " to 4" NPT threads the hand tight
2
engagement should be 5.5 to 7 threads, and for
BSPT it should be 4 threads.
4. Adjust the threads according to appropriate section of
"Adjusting Thread Size" under "Die Head Set-Up and
Use" heading.
5. Test the system in accordance with local codes and
normal practice.
Preparing Machine for Transport
1. Make sure that the REV/OFF/FOR switch is in the
OFF position and the cord is unplugged from the
outlet.

2. Clean the chips and other debris from the chip tray.
Remove or secure all equipment and material from
the machine and stand prior to moving to prevent
falling or tipping. Clean up any oil or debris on the
floor.
3. Place the cutter, reamer and die head in the operat-
ing position.
4. Coil up the power cord and foot switch cord.
5. Use care in lifting and moving, follow stand instruc-
tions. Be aware of the machine weight.

Maintenance Instructions

WARNING
Make sure that the ReV/oFF/FoR switch is in the
oFF position and the machine is unplugged before
performing any maintenance or making any adjust-
ments.
Maintain threading machine according to these
procedures to reduce the risk of injury from elec-
trical shock, entanglement and other causes.
Cleaning
After each use, empty the threading chips from the draw
tray assembly and wipe out any oil residue. Wipe oil off
exposed surfaces, especially areas of relative motion
like the carriage rails.
If the jaw inserts do not grip and need to be cleaned, use
a wire brush to remove any build up of pipe scale, etc.
Top Cover Removal/Installation
The top cover is retained by screws at each corner. The
screws are secured to the cover to prevent loss. When
removing or installing the cover, loosen or tighten the
cover screws in three steps to allow the cover to move
and flex. See Figure 27 for the tightening/loosening se -
