4. Maintenance
The utilisation level of the power source and its working environment should be taken into
consideration in planning the frequency of maintenance of the machine. Appropriate use and
preventive maintenance guarantee the best trouble-free use of the equipment. This allows you to avoid
interruptions in use and increases the productivity of the machine.
5.1 Cables
Check the condition of torch, earth and mains cables daily. Do not use damaged cables. Also make
sure that all extension cables used in the mains connection are in proper condition and compliant
with regulations.
NOTE! The mains cables should be repaired and installed only by electrical contractors and
installers trained and authorised to perform such operations.
5.2 Power source
Before cleaning the interior of the machine, you need to remove the case by unscrewing the mounting
screws at the top and sides of the machine.
NOTE! To prevent damage, wait approximately five minutes after disconnecting the mains cable
before removing the machine’s case. Perform the following cleaning and maintenance at least
every six months:
1.
Clean the interior of the machine and the fan grills net of any dust and grime stains – for
example, with a soft brush and vacuum cleaner.
•
Do not use pressurised air. The contaminant may become compressed into the grooves of the
coolers.
•
Do not use a pressure-washing device.
2.
Check the electrical connections of the machine. Clean any oxidised connections, and tighten the
loosened ones.
•
Check for the right tension before you start repairing the connections.
NOTE! Remember that the machine may be repaired only by an electrical contractor or installer
trained and authorised to perform such operations.
5.3 Regular maintenance

included in regular maintenance:
•
