Rothenberger ROPOWER 50 R Mode D'emploi page 19

Do not use force when working on the machine so that the motor cannot come to a
standstill because of an overload, for example caused by worn thread jaws!
Use only raw material that is in perfect condition for tapping 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!
To guarantee precisely ground threads, follow the instructions below:
Use the thread-tapping head and the corresponding thread-tapping jaws that matches the thread
size! Secure the thread-tapping head correctly on the tool carriage.
Do not place the thread-tapping head directly and unprotected on the floor and handle it with care!
Ensure that the thread-tapping oil runs on the thread-tapping jaws!
Lower the thread-tapping head and insert the T handle, pressing in fully in the "B" direction until the thread-
tapping jaws engage in the working position
Switch on the machine with the pedal, turn the rotary handle anti-clockwise so that the thread jaws press onto
the workpiece.
Release the rotary handle when 2 to 3 thread turns are cut.
The thread-tapping jaws open automatically via a longitudinal stop lever when the thread has been fully cut.
Switch off the machine by taking your foot off the safety pedal.
