MAINTENANCE

Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
7.1

Inspection and cleaning

Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at
reduced pressure. More frequently in dirty environments. Otherwise the air
inlet/outlet may become blocked and cause overheating. To avoid this you can use
an airfilter. The airfilter is an accessory. Ordering number on page 37.
