Cleaning The Outside Of The Radiators - Komatsu PC27R-8 Operation & Maintenance Manual

MAINTENANCE PLAN
4.7.9.d CLEANING THE OUTSIDE OF THE RADI-
ATORS
DANGER
If compressed air, steam or water are directed against a
person, they may cause injuries.
Always wear an eye shield and safety shoes.
The radiator and the heat exchanger can be reached after open-
ing the engine hood (see "3.5.1 ENGINE HOOD") and the lateral
counterweight (see "3.5.2 RIGHT COUNTERWEIGHT").
The outside of the radiators must be cleaned with a jet of com-
pressed air and, if necessary, with a low-pressure water or
steam washing cycle; the specific products available on the mar-
ket can be certainly used, provided that the instructions given on
the package are followed and that the washed parts are carefully
dried at the end of the operations.
IMPORTANT
Do not use products containing oily substances, even if in
slight quantities, since these facilitate the adhesion of
dust, which affects the heat exchange adversely.
Clean the outside of the radiators whenever the radiator
or the heat exchanger are dirtied, even if accidentally, with
oil, diesel oil, greasy or oily substances.
If the machine is used in dusty places, clean the radiator
and the exchanger more frequently, in order to avoid any
clogging of the fins.
