5. Starting and operating
The instructions of this chapter are supposed to instruct you in the operation of the machine and
to lead you during the approppriate starting of the machine.
This includes:
• the safe operation of the machine
• using all the possibilities
• running the machine economically
5.1. Starting
The machine should only be operated by trained and authorized people.
For the qualification a plastic welding exam can be taken according to DVS and
DVGW.
In case of danger unplug the machine immediately.
In case of power failure, the hydraulic system can still be under pressure.
For this reason, release pressure when required.
After completion of the welding work and during breaks the machine has to be
switched off. Further be sure that no unauthorized persons have access.
Protect the machine from wetness and moisture!
Operating the machine on construction sites is only allowed with an in-coming power
distributor with a FI safety switch according to VDE 0100.
Check the oil level of the hydraulic system before each starting in order to avoid
damages on the pump.
The oil-level must be between the two markers.
Connect the power line plug of the hydraulic aggregate to the mains, and be sure to have a
correct mains voltage (230 V / 50 Hz).
Connect the heating element and planer to the corresponding plug box of the aggregate.
Connect the hydraulic hoses of the basic machine to the aggregate.
Lay hydraulic and electric lines carefully (danger of stumbling) !
Take into consideration the environmental conditions:
• Welding should not be carried out in direct sunlight.
• If necessary put up a welding tent.
• In case of ambient temperatures below 5°C the following measures have to be taken:
If need be, put up a welding tent and heat up the pipe ends.
• Take measures against rain, wind and dust.
