10.5 Cooler maintenance
The respective engine and compressor coolers are arranged together in a radiator block.
Heavy contamination of both coolers will result in cooler overheating, and therefore overheating of
the machine. The frequency of cleaning is mainly dependent on local operating conditions.
Check both coolers regularly for clogging. A severely contaminated cooler/radiator should be
cleaned by KAESER SERVICE.
