Maintenance Instructions
WARNING
Make sure the ON/OFF switch is in 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
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 chip
try and wipe out any coolant residue. Wipe any coolant
present off of 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, cutter feedscrew, jaw inserts and pivot points) with
a light lubricating oil. Wipe any excess oil from exposed
surfaces.
Replacing Cutter Wheel
If the cutter wheel becomes dull or broken, push cutter
wheel pin out of frame and check for wear. If needed re-
place pin, and install new F-3 Cutter Wheel (Catalog
Number 33105). Lubricate pin with light lubricating oil.
Replacing Jaw Inserts
If Jaw inserts are clean and don’t grip pipe, they need to
be replaced.
1. To remove jaw insert – place punch into spring de-
tente slot of jaw insert and push down.
(Figure 16)
2. Continue to push down on spring detente and slowly
slide jaw insert out of chuck jaw holder. Remove jaw
insert.
3. Install new jaw insert – place into chuck jaw holder
and with finger depress spring and plunger. Slowly
move jaw insert past spring and plunger until insert
fully sits in chuck jaw.
Figure 14 – Checking Thread Size
4. If the thread is too large (ring gauge will not thread on
far enough) adjust the die head size bar slightly to-
ward the UNDER marking
(See Figure 8). If the
thread is too small (ring gauge threads too far onto the
thread) adjust the die head size bar slightly toward the
OVER marking
(See Figure 8).
5. Test the system in accordance with local codes and
normal practice.
Preparing Machine for Transport
1. Make sure that the ON/OFF 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.
3. Push the reservoir vent down to close. Make sure the
reservoir vent cap is tightly screwed down.
4. Place the cutter, reamer and die head in the operat-
ing position.
5. Coil up the power cord and foot switch cord and
hook the foot switch on the clip next to the reservoir
(See Figure 15).
