Threads
If there is a dangerous situation, release foot from
pedal. 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 cut 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 die head directly and
unprotected on the floor and handle it with care!
Ensure that the thread oil runs on the dies!
