300 Compact/1233 Threading Machines
• 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 / " to 3" NPT threads the hand

tight engagement should be 5.5 to 6 threads, and
for BSPT it should be 4 threads.
4. See "Adjusting Thread Size" under "Die Head Set­Up
and Use" heading to adjust thread size.
5. Test the piping system in accordance with local codes
and normal practice.

the OFF position and the machine is unplugged
before performing any maintenance or making any
adjustments.

Always wear eye protection.
Maintain threading machine according to these pro­
cedures to reduce the risk of injury from electrical
shock, entanglement and other causes
Cleaning
After each use, empty the threading chips from the chip
tray 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.
Lubrication
On a monthly basis (or more often if needed) lubricate
all exposed moving parts (such as carriage rails, cutter
wheels and rollers, cutter feed screw, jaw inserts and
pivot points) with a light lubricating oil. Wipe any excess
oil from exposed surfaces.
Clean the lubrication points to remove dirt and prevent
contamination of the oil or grease. Lubricate on a monthly
basis.
300 Compact: Use a grease gun to add a Lithium EP
(Extreme Pressure) grease through the grease fittings in
the lubrication points.
1233: Fill the lubrication points with lubricating oil. Press
the ball in the lubrication point to allow the oil to reach
bearings.
