6 © 2002 6.3 Cooling System Service and Maintenance Cold Cleansing Agent Spray the heat exchanger with a com- mercial cold cleansing agent and let stand for about 10 minutes. First spray clean with a water jet from position 3 then from position 1 (do not spray sensitive engine components directly with a water jet, eg generator, cables, electronic components, fan drive). Cleaning with steam or with hot water Remove oil and grease residues with the jet set at a gentle setting. Hose pressure: max. 100 bar Because applications vary, cleaning in- tervals have to be determined from case to case. The cleaning intervals given in the table below can be used as a guide.
Series 1012/1013 Place a cleaning bath under the heat ex- changer (it. 2). Remove the service flap on the heat ex- changer (see insert). Compressed Air Blow out heat exchanger with com- pressed air (first from it. 3, then from it. 1). Be careful not to damage the cooling fins. Wash out loosened dirt with a hose. 6.3.1 Cleaning Intervals The amount of contamination in the cooling system depends on the engine application. Spilled oil or fuel on the engine increases the risk of contamination. Be especially careful if the engine is used in dusty environments. Serious contamination can occur, for example: on construction sites where there is a high level of air-borne dust.
in harvesting application where there are high concentrations of chaff and chopped straw in the vicinity of the machine.
