Threading a tube
The machine is supplied as standard with a die head for threading tubes with diameters from 1/2” to 2”.
Optionally available is a head for threading tubes of 1/4” to 3/8” diameter (part no. 162150).
Producing a thread
Install the appropriate head for the tube diameter (see pages 25 and 28 for the procedures
for installing 2” and 1/4 – 3/8” heads).
Position the tube as indicated on page 18.
Important: Position the tube such that the end to be threaded is
well to the right of the red
line
on the front post of the saddle:
The saddle must not go past this limit: doing this will tear the thread and could even
cause the tube to crack.
Thread: Select position R (R for Right).
Position L ( L for Left) is used to have the motor rotating leftwise.
To switch direction of rotation à l’autre, it is imperative to hold the switch on the 0 position as
long as the motor has not stopped.
Start the motor. Rotation to the right (R).
Adjust the oil flow so as to obtain sufficient lubrication and no excess oil. The oil flow regulating
wheel is located on the rear panel, right hand side, of the machine:
Important:
Never cut a thread on a tube without a sufficient oil flow. You risk damaging the
tube, the die and the machine.
