5. To insert the head into the adapter, move the mobile part of the latter counter-clockwise until it is
completely inserted. This will spring back securing the head. To remove it, proceed in likewise manner.
6. Next insert the machine in the tube and make sure that it is securely guided into its housing by the tube
clamp bolt.
7. Check that the reverse gear lever is correctly in place (arrow in working direction). Press the electric switch
with your right hand. Rotation will start immediately. Now the head should be moved towards the tube
to start the threading process by pressing on the machine.
8. As soon as threading has begun, the head should be constantly and abundantly lubricated with threading
oil ROTHENBERGER.
9. Once the appropiate threading length has been achieved (the tube of the threading head should
never overhang in a normal thread), stop the motor. Change the position of the reverse gear lever
and start the motor. The machine will begin to unscrew the head and the tube will become free.
ATTENTION! Fast speed must only be used to unscrew the head. Never thread on fast speed.
