Threads

If there is a dangerous situation, press the safety pedal right down. This stops the machine.
To restart the machine, press the release button on the side of the safety pedal.
To guarantee precisely ground threads, follow the instructions below:
Use only raw material that is in perfect condition for threads.
If you use deformed and / or pipes cut off at an angle, it is not possible to tap threads that
conform to the relevant standards!
Use the thread- head and the corresponding thread- jaws that matches the thread size!
Secure the thread- head correctly on the tool carriage.
Do not place the thread- head directly and unprotected on the floor and handle it with care!
Ensure that the thread- oil runs on the thread- jaws!
For the standard thread- head:
Lower the thread- head and move the opening and closing lever down towards you.
Turn T.O.R.-switch to "thread" and switch on the machine with the pedal, turn the rotary
handle clockwise so that the thread jaws press on the workpiece.
Release the rotary handle when two to three threads have been cut.
With the machine running, slowly move the opening and closing lever up when the required
number of threads has been cut, so as to end the cutting process by slowly opening the
thread jaws.
If the thread jaws are opened jerkily, steps can be created in the last section of the thread, with
the result that the thread is faulty!
