Air conditioning (optional equipment)
Condenser, cleaning
Clean the condenser every 500 hours or as needed.
1 Place the machine in service position, see page 95.
2 Let down the front grille.
3 Open up the engine hood.
4 Blow the condenser clean with compressed air.
In order to prevent leaks and to safeguard lubrication of the seals
in the compressor for the air conditioning, the air conditioning
system should be run for approx. five minutes once a month. It is
important that the machine operator is made aware of this.
NOTE! At temperatures below freezing, 0 °C, the unit must be
run indoors, if possible, as the power supply to the
compressor lead is switched off by the thermostat whenever
the evaporator temperature is below +1 °C.
Make sure that the exhausts are extracted or ventilated in a
suitable way.
Be careful with the hoses between compressor, condenser, and
evaporator. There is always high pressure in the system.
Therefore, never loosen hoses and never loosen the oil filler plug
on the compressor, except during repairs to the system.
Ask a workshop authorised by Volvo CE check the air conditioning
system once a year.
Compressor, checking belt tension
Check the belt every 2000 hours.
The belt is a flat Poly-V type, with automatic belt tensioning. The
belt is common for the alternator and compressor.
NOTE! The belt guard has been removed in the picture.
Change the belt if any of the belt's ribs is missing.
