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 case of power failure, there may still be pressure in the hydraulic system.
Therefore release pressure if need be.
In situations of danger for persons and the machine, press the emergency stop or
push lever <Terminal> to: Off.
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.
Protect the machine from wetness and humidity !
According to VDE 0100, the use on construction sites is only allowed with a
power distributor with a FI-security protective switch.
Check the oil level of the hydraulic system before each starting of the control unit
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
fiber-free paper
and a cleaning agent (e.g. PE cleaner or pipe
cleaning tissues which are available at the WIDOS company).
Never discard the heating element unprotected onto its coated surfaces.
The anti-adhesive coating of the heating element must remain undamaged in the
working area.
Take care that all hydraulic and electric connections are connected.
Make sure that pumps and planer are connected in a way that they turn in right-
handed direction otherwise change turning direction.
Take into account the surrounding conditions:
-
The welding may not be performed under direct sun rays influence.
-
Use a welding umbrella if necessary.
If the surrounding temperature is under 5°C, measures have to be taken:
-
Use a welding tent or preheat the pipe ends if necessary.
In addition, take measures against rain, wind and dust.
