5.4 Removing and installing the dies (E)
Wear gloves in order to prevent cut injuries to the hands caused by the dies!
Removal:

Ensure that the locking lever is not pulled and lift out the die head.
 Pull the locking lever into the “A” position in order to open the dies (fig. 1).
 Move selector plate into the “B” position and remove the dies (fig. 1).
Installation:

Insert the dies with the same number as on the respective die head and make sure it en-
gages audibly (fig 2).
 Ensure that the numbers on the die head and on the dies are on the same side.
 Move selector plate into the “C” position until the locking lever is fixed (fig. 3).
Precise thread cutting is only possible if the number on the slot of the die head
corresponds with the number on the die!
After changing the dies, check that they are secure! After changing the die head or
replacing the dies, check that they are locked securely in the tool carriage!
5.5 Changing the thread size (F)
 Ensure that the die head is on the tool carriage and that the dies 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).

 To restart the machine, press the blue 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 cutting 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 die head and the corresponding dies that matches the thread size! Secure the die
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 cutting oil runs on the dies!
 Lower the die head and insert the T handle, pressing in fully in the “B” direction until the
dies engage in the working position (fig. 1).
 Switch on the machine with the pedal, turn the rotary handle anti-clockwise so that the dies
press onto the workpiece (fig. 2).
 Release the rotary handle when 2 to 3 thread turns are cut.
 The dies 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.
