5. MAINTENANCE
The amount of use and the working environment should be taken into consideration
when planning the frequency of maintenance of the machine. Careful use and preventive
maintenance will help to ensure trouble-free operation.
5.1 Cables
Check the condition of welding and connection cables daily. Do not use damaged cables.
Make sure that the mains cables in use are safe and according to laid down regulations.
The repair and mounting of a mains connection cable should be carried out only by an
authorised electrician.
5.2 Power source
NOTE! Disconnect the plug of the machine from the mains socket and wait approx. 2 minutes
(capacitor charge) before removing the cover plate.
Check at least every half year:
• Electric connectors of the machine – clean the oxidised parts and tighten the loosened
ones.
NOTE! You must know correction tension torques before starting the reparation of the joints.
• Clean the inner parts of the machine from dust and dirt e.g. with a soft brush and
vacuum cleaner. Also clean the ventilation net behind the front grate.
• Do not use compressed air, there is a risk that dirt is packed even more tightly into gaps
of cooling profiles.
• Do not use pressure washing device.
• Only authorised electrician shall carry out repairs to the machines.
