Checking contamination of the air filter
Air filter maintenance is necessary when the yellow piston inside the maintenance indicator reaches
the red zone.
➤ Check the air filter maintenance indicator.
If the yellow piston reaches the red zone, clean or renew the filter element.
Cleaning the air filter
1. Release the retaining clip. Lift off the cap and extract the element.
2. Clean the inside of the housing, the cover and sealing faces carefully with a damp cloth.
3. Clean the filter element
■ Use dry compressed air (≤ 5 bar) at an angle to blow dirt from the element from inside to
outside.
■ The blast pipe must be long enough to reach right into the element.
■ The tip of the blast pipe should not be allowed to touch the element.
■ Clean sealing faces.
4. Inspect the element carefully for any damage.
Renew a damaged element.
5. Insert the cleaned or new filter element into the filter housing. Make sure it is properly in place
and sealed by its gasket.
6. Replace the cap and secure with the clip.
Resetting the maintenance indicator
➤ Press the reset knob on the maintenance indicator a number of times.
The yellow piston within the indicator is reset and the maintenance indicator is ready for use
again.
➤ Close the doors.
10.5.8 Checking pressure relief valves
➤ Have pressure relief valves checked by KAESER Service in accordance with the maintenance
schedule.
10.6 Cleaning the coolers and radiator
The compressor oil cooler and engine coolant radiator are combined in a single cooler block.
The frequency of cleaning is mainly dependent on local operating conditions.
Heavy clogging of the cooler/radiator can cause oil overheating and overheating of the engine.
Check the cooler/radiator regularly for clogging.
Avoid creating dust eddies. Wear breathing protection if necessary.
Do not clean the cooler/radiator with a sharp instrument, otherwise it could be damaged.
A severely contaminated cooler/radiator should be cleaned by KAESER Service.
