Installation:
 Insert the thread jaws with the same number as on the respective thread-tapping head and
make sure it engages audibly (fig 2).
 Ensure that the numbers on the thread-tapping head and on the thread jaws are on the same
side.
 Move selector plate into the "C" position until the locking lever is fixed (fig. 3)
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!
After changing the thread-tapping jaws, check that they are secure! After
changing the thread-tapping head or replacing the thread-tapping jaws, check
that they are locked securely in the tool carriage!
5.5 Changing the thread size
 Ensure that the thread-tapping head is on the tool carriage and that the thread jaws
correspond to the thread size.
 Insert the selector pin into the selector block with the necessary thread size (fig. 1).
 The size is shown on the respective selector block.
 Push T handle towards "D" to set dies (fig. 2).
5.6 Tapping 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 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!
 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 (fig. 1).
 Switch on the machine with the pedal, turn the rotary handle anti-clockwise so that the
thread jaws press onto the workpiece (fig. 2).
 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.
