10.14.1 Checking cylinder head and valves
To check the valves' function, check the time required to charge the air receiver.
Precondition Machine at operating temperature.

2. Switch on the machine and measure the time required to charge an air receiver.
Result If you find considerable differences in the filling time compared to the machine's status after deliv‐
ery, check the valves for coking.
Further information See chapter 7.7 for more information about measuring the charging time for air receivers.
