6.3.2 Clean Cooling System
• The amount
of
contamination in the cooling
system dependson the engine application.
• Oil and fuel residues on theengine increase
the risk
of
contamination. Therefore pay
special attention to leaks if the engine is
used in dusty environments.
• Seriouscontamination occurs, forexample:
- on construction sites where there is a high
level
of
air-borne dust.
-
in
harvesting applicationswhere there are
high concentrations
of
chaffand chopped
straw
in
the vicinity
of
the machine.
•
Because
applications
vary,
cleaning
intervals have to be determined from case
to case. The cleaning intervals given
in
the
table below can be used as a guide.
