Daily Inspection
Check the rotating unions for tightness.
Risk of injuries due to applied line pressure
If you have to work on the rotating union and feed pressure of the medium is applied
or there is residual pressure in the piping system of the machine, the medium can es-
cape under pressure when releasing the connections. You and other people may suffer
severe injuries.
❑
Ensure that no feed pressure is applied.
❑
Ensure that there is no residual pressure in the piping system.
During the operation of the machine, leakage might occur,
the time period is subject to the extent which the rotating
unions are used.
❑
Carry out daily visual inspections in order to check whether
leakage occurred at the rotating union (see arrows).
If you detect leakage:
1. Stop the machine.
2. Replace worn out or leaking rotating unions with new ro-
tating unions.
3. Replace defective hoses with new hoses.
4. Seal leaking connections.

1. Which problem may occur?
2. What could be the cause of the problem?
3. How can you eliminate this problem?
Do not disassemble the rotating unions for repair. This invalidates the warranty claim.

Potential Causes for Errors and their Elimination
Risk of injuries due to applied line pressure
If you have to work on the rotating union and feed pressure of the medium is applied or
there is residual pressure in the piping system of the machine, the medium can escape
under pressure when releasing the connections. You and other people may suffer seri-
ous injuries.
❑
Ensure that no feed pressure is applied.
❑
Ensure that there is no residual pressure in the piping system.
