Safety instruction
For tapping, use ROTHENBERGER high-performance thread-tapping oil art. no. 6.5010. This oil
is not suitable for tapping drinking water pipes!
Alternatively, you can use ROTHENBERGER high-performance thread-tapping fluid, art. no.
6.5015. This fluid is suitable for tapping all pipelines (including drinking water pipelines).
Precise thread-tapping is only possible if the number on the slot of the thread-tapping head
corresponds with the number on the thread jaw!
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!
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!
Apply anti-rust grease if the machine is not going to be used for an extended period!

Operating B
1. Installing the thread jaws from and in the thread-tapping head
Wear gloves in order to prevent cut injuries to the hands caused by the
thread jaws!
Î Release the die holder (1), bring the cradle (2) into the lowest position, tighten the die and
move the opening and closing lever (3) up to remove the thread jaws.
Î Insert the thread jaws with the same number as on the respective thread-tapping head and
make sure it engages audibly.
Î Ensure that the numbers on the thread-tapping head and on the thread jaws are on the
same side.
2. Changing the thread size
Î
Balance the reading-off device on the cradle (2) with the defined measuring division on the
scale plate (4)
3. Tapping threads
Î
Lower the thread-tapping head and move the opening and closing lever (3) down towards
you.
Î Switch on the machine with the pedal; turn the rotary handle clockwise so that the thread
jaws press on the workpiece.
Î Release the rotary handle when two to three threads have been cut.
Î With the machine running, slowly move the opening and closing lever (3) 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!
