7.4.5 Cleaning the cooler
The machine is equipped with separate cool-
ers for combined water/charge air cooling and
the hydraulic oil.
Danger of injury due to rotating
parts and hot surfaces
• Cleaning jobs must only be car-
ried out when the diesel engine is
turned off and has cooled down.
In an emergency: Administer first
aid, seek treatment from a doctor
Diesel engine overheating can re-
sult in damage to the machine.
Carefully clean away any dirt that
becomes attached to the coolers.
►
Clean the combined water/charge air cool-
er (262/2) and the hydraulic oil cooler
(262/1) from the outlet side with com-
pressed air. Maintain a safe distance to
avoid damaging the cooler flaps!
►
Clean the engine compartment (remove
deposits of dirt, oil and diesel fuel).
►
Blow the engine off with compressed air or
clean it with a cold cleaner. Wash off the
loosened dirt with water. (Do not spray a
direct jet of water against sensitive engine
parts, for example generator, starter, ca-
bling, electronic components, connectors.)
►
After every wet cleaning operation, let the
diesel engine warm up so that water resi-
due evaporates and corrosion formation is
avoided.
If necessary (if the cooler is dirty, for example)
use a cold cleaner or a high-pressure cleaner.
►
Place the machine on a washing surface
equipped with an oil separator.
►
Clean the machine with a high-pressure
cleaner.
►
After cleaning, bring the drive motor to op-
erating temperature to dry out the cooler.
