6 MAINTENANCE
6.1 General
WARNING!
During all maintenance or repair procedures, the roller beds must be electrically isolated.
Switch off the main electrical supply and unplug the mains cable.
WARNING!
After disconnecting the power, there may be some residual charge in some components in the
panel. Wait for a few minutes after disconnecting the mains power before commencing work
on any electrical elements of the roller bed.
The installation procedure must be carried out after maintenance, repair, or storage period, see
section "Installation procedure".
6.2 Storage
Store the roller beds in a cool dry place. After a long period of storage, the roller beds must be
thoroughly checked before use.
WARNING!
When the roller beds are stored or transported in a cold climate and moved into a warm
location, condensation can be built up in the roller beds or the electrical controls. To prevent
damage, allow the roller bed to adjust to the new environment temperature.
CAUTION!
Do not store the roller beds outside unprotected. The roller beds must be sheeted, bare metal
areas, bearings, gears, and shafts suitably greased to prevent corrosion.
6.3 Repair and maintenance
Keep the roller beds clean and free from dirt or waste from the welding process.
Check the gearbox oil regularly and keep it at the correct levels. See the "Gearbox maintenance"
section.
Inspect the entire roller beds installation at least once per year. Pay particular attention to:
• Electrical contacts
• Switches and controls
• Mechanical parts, fixings are not loose.
• Condition of PU wheels
• Wheel rotation is full and there is no eccentric rotation around the axles.
• Metal corrosion
• Frame damage
• Signs of damage to the wheel bearings
• Gearbox maintenance
• Cable damage: mains and any visible cable running from the control panel to the motors.
• Correct functioning of the emergency stops and the control panel mains switch.
Remove and replace any damaged parts.
