5 Starting and operating
The instructions of this chapter are supposed to initiate in the operation of the machine and lead
during the appropriate starting of the machine.
This includes: - the safe operation of the machine;
- using all the possible options of the machine;
- economic operation of the machine.
5.1 Safety indications

The machine may only be operated by initiated and authorized persons.
For the qualification, a plastic welding exam can be taken according to DVS and DVGW.

In situations of danger for persons and the machine, the mains plug has to be unplugged
immediately.

After completion of the welding work and during breaks the machine has to be switched off. Further
take care that no unauthorized person has access.

According to VDE 0100, the use on construction sites is only allowed with a power distributor with a
FI-security protective switch.
5.2 Starting
Check the oil level of the hydraulic system before each starting of the machine in order to
avoid damages on the pump.
If necessary, add hydraulic oil of the quality HLPD 32.
The heating element surfaces must be clean, especially non greasy, therefore they need
to be cleaned shortly before each welding or in case of dirtiness by means of a fibre-
free paper and a cleaning agent (e.g. PE – cleaner or pipe cleaning tissues which are
available at the WIDOS company).
The anti-adhesive coating of the heating element must remain undamaged in the working
area.
For reason of a high fire risk, the heating element may be only cleaned in cold condition.

Connect the hydraulic hoses of the basic machine with the hydraulic aggregate.

Connect hydraulic aggregate to the mains supply 400 V / 50 Hz / 32 A.

Connect planer and heating element to the hydraulic aggregate.

Make sure that pump and planer are connected in a way that they turn in right-hand direction, if
need be correct it.
Replace the screw plug by the enclosed venting screw before starting the
planer (see arrow).
Do not throw away the screw plug, you need it again when transporting the
planer!
