6.4 Cleaning
WARNING!
Roller beds must be electrically isolated before cleaning. Electrical components must not come
in contact with water or other cleaning fluids.
NOTE!
Ensure that the roller beds are clean. Any arc sparks, flux or slag must be removed from the
roller beds as soon as possible.
Frequently check that the equipment is free from any damages, mechanical or electrical. At
least one time a month.
The roller beds do not require any special cleaning instructions. The roller beds do not create any
pollution to the environment around them during normal operation, although, the welding process
being carried out on them may pollute the roller beds.
6.5 Breakdowns
If the roller beds stop working, the equipment must be repaired by authorized ESAB service
technicians.
NOTE!
Repeated faults indicate a problem with the roller beds. Inform the person responsible for
service and maintenance.
6.6 Gearmotors
6.6.1 Gearmotors inspection and maintenance
To ensure that the roller beds have a long service life the oil in the gearbox must be regularly checked
and changed.
Regular maintenance checks:
• Under normal working conditions and with an oil sump temperature not exceeding 80°C the service
life of the oils is 10000 operation hours or two years, whichever comes first.
• Check if the seal is leaking or damaged.
• Check if there are any unusual noises during operation. If yes, the bearing may be broken.
• Check the breathing hole of gearbox is obstruction free.
• To aid cooling of the gearbox it is recommended that the external housing is kept clean.
• Check the bolts, tighten if loose.
6.6.2 Gearbox lubrication
The gearboxes on the roller beds were filled with the proper quantity of lubricant
(CLPISOVG220:FuchsRenolinCLP220) before shipping from the factory.
