4.6 Air Conditioning (optional)
The loader is equipped with an air conditioning unit that
allows the driver to set the desired temperature, thus
guaranteeing improved operator response and considerably
enhancing operator concentration. At the same time, the
air conditioning unit dehydrates the air entering the cab,
preventing condensation and steamed up windows, and
allowing for better visibility. Additionally, the air conditioning
unit uses dust filters to filter the air, at the same time
preventing dust and other unpleasant or harmful substances
from entering the cab by permanently generating slightly
raised cab pressure.
To ensure perfect working order and full performance, the
compressor must be engaged once a week for a short
period, in order to lubricate the internal gaskets.
If the ambient temperature is low, the compressor should
not be switched on until the engine has reached running
temperature. The coolant, which in fluid state tends to
collect at the lowest point in the compressor circuit,
assumes its gaseous form due to engine heat. Fluid
coolant can cause damage to the compressor.
DANGER
- Due not attempt to open the air conditioning
circuit, as this will cause coolant loss.
- The coolant circuit contains gas which can be
dangerous in certain circumstances.
ATTENTION
- The air conditioning unit should be maintained
by trained and authorized staff only.
- The compressor has an oil fill-level gage. Do
not remove the gage, as this will empty the
unit. The oil fill-level does not need to be
checked, except when emptying the air
conditioning circuit.
NOTE
If the circuit develops a leak, the air conditioning
unit will become ineffective.
