10.6 Cleaning the cooler
The frequency of cleaning is mainly dependent on local operating conditions.
Severe clogging of the coolers causes overheating and machine damage.
Check coolers regularly for clogging.
Avoid creating dust eddies. Wear breathing protection if necessary.
Do not clean the coolers/radiators with a sharp instrument as they may be damaged.
A severely contaminated cooler/radiator should be cleaned by KAESER SERVICE.
