Thread cutting medium and oils
Use ROLLER thread cutting mediums and oils.
Never cut threads dry!
Choose the riqht lubrication according to material and use.
Use all thread-cutting medium and oils only undiluted!
2.2.1. Thread cutting medium Rubinol 2000: Red cutting oil free of mineral oil
(DVGW-Check-No. DW-0201AS2031). For all types of threads, espe-
cially for drinking water.
2.2.2. Thread cutting oil Smaragdol: Cutting oil with mineral oil concents.
Suitable for all types of thread and material. Observe regulations when
working on drinking water pipes.

Operating
3.1.
Fitting the die head (1)
Insert Central or Rola Automatik die head in die head receiver or adaptor,
turn until arresting lever engages (see Pic. 2 and 4).
3.1.1. Functioning of die heads
The die heads Rola Automatik open automatically when the standard
lenght is reached.
The Central die heads have to be reversed.
Only operate change-over switch (8) when motor is stationary!
3.1.2. Functional check of the die head Rola Automatik
Check the function of the automatic die heads when die heads are new
or after long storage:
Operate tensioning stirrup a number of times, pull = open, push = close.
3.1.3. Support bracket. The support bracket (3) serves to support the die stock
against of torque in both directions of rotation, i. e. for advance and
reserve rotation of the die head, for right- and left hand threading. Support
bracket must always he used!
3.2.
Thread cutting
3.2.1. Fasten support bracket approx. 10 cm before end of pipe, by attaching
it, so that the pipe is centered in between the jaws (4) and spindle (5).
Locking handle has to be tensioned tightly. Before threading, pipe end
should be slightly oiled. Then the threader has to be attached to the pipe
with the bracket between handle (6) and motor housing (7). Adjust
change-over switch (8). After having checked the rotation (R – right
hand thread or reverse for left hand thread L – left hand thread or re-
verse for right hand thread), press on/off-switch (9) while simultaneously
gripping the handle (11) (Pic. 6).
3.2.2. Starting cutting
Press the electric threaders against the pipe until the die head starts to
cut. During cutting sufficient lubrication is necessary.
3.2.3. Reversing and removing the electric thread cutter
With the use of Central die heads, the thread is finished when the dies
are level with the end of the pipe. Release the rocker switch and set the
changeover switch to position L (operate the changeover switch only
when the machine is at a standstill). Now switch on the thread cutter
again. The die head will retract away from the thread. With the machine
at a standstill, set the changeover switch to position R. The retraction
process does not take place with Rola die heads.
Rola die heads open automatically when the standard lenght is
reached (Pic. 5).
