Ensure that the oil tank is filled with oil up to the level of
the sieve mesh.
If the amount of thread-tapping oil running via the thread
tapping head does not meet the requirements, the sup-
plied amount must be adjusted with the aid of the oil ad-
justment screw.
Undo the locking nut of the oil adjustment screw.
Turning the oil adjustment screw clockwise increases the
amount of oil delivered and turning it anti-clockwise re-
duces the amount.
Tighten the locking nut firmly after making the adjustment.

Draining off the oil
It is essential to also observe the safety and disposal
regulations in Chapter 9!

Operation of the threading machine
5.1
Clamping the workpieces
The tool carriage can make contact with the frame before the tapping process has ended
and the clamping chuck and the machine can be damaged as a result! A clearance of at
least 70 mm must therefore be maintained between the thread cut on the workpiece and
the clamping chuck!
Move the pipe cutter and the thread-tapping head up so that they are not in the way and po-
sition the internal deburrer on the rear side.
Insert the workpiece from the centring chuck side (fi g.1) and tighten the centring chuck
(fig.2).
Hold the workpiece on the clamping chuck side securely with your right hand and gradually
tighten it with the clamping chuck (fig. 3).
Ensure that the three clamping jaws are in contact with the workpiece.
If the three clamping jaws are not in contact with the workpiece, it will wobble and neither
cutting nor thread cutting can be performed correctly!
Clamp the workpiece securely and tighten it very firmly.
In the case of long or heavy pipes, it is essential to use the pipe support Art. No. 56047 in
order to prevent the workpiece wobbling or twisting while it is being turned and to prevent
the machine from tipping over due to the weight of the workpiece! Otherwise, the work-
piece and the machine can become unstable!
5.2
Cutting the workpiece with the pipe cutter
Do not touch the cutting surface with bare hands, because it is hot and has sharp
edges! Risk of injury and burning!
