For efficient use
l If the inside of the operator’s cab is hot after the machine has
been parked for a long time in the sun, open the windows and
doors fully to cool the operator’s cab before switching on the
cooler.
l When using the cooler, make sure that the windows and doors
are properly shut.
l If there is dirt or mud on the condenser, the cooler will not cool
properly.
When washing or checking the machine, always remove all dirt
and mud from the condenser, to ensure a good flow of air.
l For reasons of health, the temperature inside the cab should not
be adjusted too low. As a general rule, the temperature should
be kept at a maximum of 5 to 6°C below the outside temperature,
enough to feel cool when entering the cab.

If the cooling effect is poor, check the side glass (liquid eye) of
the receiver drier. If there are many bubbles, the coolant level is too
low. Check whether there is any coolant, and have the cooler
serviced.

If there is any dirt or mud stuck to the condenser, there will be
a big reduction in the cooling efficiency of the condenser. That will
mean a reduction in the cooling capacity, so clean the dirt and mud
off and correct any bent fins with a screw-driver.
