10.14 Cylinder head and valves

The condition of the valves can be assessed by measuring the air receiver charging time and com‐

paring this with the charging time when the machine was new.

Precondition Machine at operating temperature.

➤ Start the machine and measure the receiver charging time.

Result If there is a significant difference in the charging time to when the machine was new, have

KAESER Service check or replace the valves.

Further information See chapter 7.5 for air receiver charging time measurement.
