9.4 Spare parts and repair work

Afag Automation AG offers a reliable repair service. Defective rotary modules

can be sent to Afag for warranty repair within the warranty period.

Please note that Afag does not assume any warranty for rotary modules that

have not been replaced or repaired by Afag!

NOTICE

Risk of damage to property!

The operation of the rotary modules with oil-lubricated compressed air causes

the factory primary lubrication to be washed out. Therefore, it is absolutely

essential that the rotary modules continue to be operated with oil-lubricated

compressed air in order to avoid damage to the rotary modules.



Once the rotary modules have been operated with oil-lubricated

compressed air, they

may never be operated without oil-lubricated

compressed air

CAUTION

Risk of injury when removing the rotary modules due to uncontrolled

movements of the rotary modules!

When disassembling the rotary modules from a system, there is a danger of

uncontrolled movements.



Disconnect the media supply (electrics, pneumatics) before removing the

modules!



Disassembly should only be carried out by qualified personnel!



Bleed and deactivate the equipment before removing the rotary module!



Before removing the rotary module, switch off the control unit and secure it

against being switched on again!
