10.5 Cooler maintenance
Regular cleaning of the cooler ensures reliable cooling of the machine and the compressed air.
The frequency is mainly dependent on local operating conditions.
A leaking cooler results in loss of cooling oil and compressed air.
Clogged coolers are indicative of unfavorable ambient conditions. Such ambient conditions
clog the cooling air ducts in the machine's interior and the engines resulting in increased
wear and tear.
➤ Have the authorized KAESER service representative clean the cooling air ducts.
Material Brush and vacuum cleaner
Face mask (as required)
Precondition The power supply isolating device is switched off,
