Connect power plug with local power supply 400 V / CEE-16 A / 50 Hz, right rotary field.
After connecting the machine, check rotating direction of the current.
Therefore press button: <
> and let the planer rotate
max. 1 – 2 times
.
The knives will cut in the right rotating direction otherwise change direction.
In case of a wrong rotating direction, there is the danger of damaging the
hydraulic pump!

A stop-watch should be available for recording the actual times for the heating and cooling.
The heating element surfaces are to be clean and, above all, free from grease. Therefore
they are to be cleaned with non-fraying paper and detergent (e.g. PE - cleaner) before
every welding or if they are dirty.
The anti-adhesive coating of the heating element has to remain undamaged in the working
area.
Do wear safety gloves as protection against burning.
Clean the heating element only in cold condition
danger of inflammation
caused by cleaning agents.
Make sure that nobody can touch the hot heating element; particularly be
cautious while driving the heating element back.
Make sure that nobody can reach into the driving area of the planer while driving
the planer in and out!
Let the planer discs rotate only if the planer is in working position and locked
there.
A table must be available from which the parameters for the pipe dimensions to be welded
prescribed by the welding prescriptions may be taken.
Activate main switch at the right side of machine.
As soon as the main switch are activated, the heating element is heated up to the set
welding temperature by means of the temperature controller (reference value PEHD: 210°C,
see also chapter 4.3). If the temperature is displayed without flashing dots, temperature has
been reached and is kept via a pulse-interval method.
Mount the reducer inserts for the respective pipe size into the upper and lower clamping
tools (chapter: 4.7.1).
Check whether the star screw: is <
> tightened to release or hold the pressure. Tighten
the screw firmly if necessary, otherwise no pressure build-up is possible
