Functional Test
The functional test is done on the GFA module disconnected from the tool.
Perform a functional test before the first tightening operation, and after any performed maintenance activities.
To perform a functional test:
Turn the output gear wheel by hand or by using a socket. It should be turned easily.
If it is hard to turn, open the housing and check that all components are in the correct position. If issues persist, contact Atlas Copco Customer Center.
Lubricate the system.
