The machine should 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 EMERGENCY-Stop push button or
the main switch have to be activated immediately.
•
After completion of the welding work and during breaks, the machine has to be switched off.
Further be sure 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-safety 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 should 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
cleaning agent (e.g. technical pure alcool or
cleaning tissues which are available at the WIDOS company).
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.
