Air Conditioner
CAUTIONS ON USE
Ventilate periodically
¡
When using the air conditioner over an
extended period of time, open the
windows about once each hour to let in
fresh air.
¡
Your eyes may become irritated if you
smoke while using the air conditioner. If
this happens, open the windows to let in
fresh air. Cigarette smoke particularly
irritates the eyes when using the air
conditioner because the humidity in the
cabin drops and the eyes’ membranes
tend to become dry.
Always maintain good visibility
Working with the windows dirty or fogged
restricts visibility and is dangerous. Always
clean dirt and moisture off the windows
before working.
¡
The windows tends to get foggy when the
humidity is high. If this happens, turn on
the air conditioner and use outside air and
the defroster to get rid of the fog.
¡
If the air conditioner is set to high when
using the defroster, the difference between
the external and internal temperatures
increases, and fog may form on the
outside of the windows. If this happens,
either turn the air conditioner off or turn
the temperature control dial clockwise to
increase the internal temperature.
¡
Mist may blow out of the air outlets. This
is not a malfunction. When moist air
passes through the air conditioner unit’s
evaporator, water particles in the air freeze
and are emitted as mist.
Do not overcool
For health purposes, the air inside the cab
should be kept at a temperature at which you
feel a little cool when entering the cab from
outside (a difference of 5 to 6
°
C (9 to 11
°
F)).
Be careful to adjust the temperature properly.
Do not turn the air conditioner on
until the engine is started
To avoid placing an excessive load on the
compressor, wait until the engine is started
and is running smoothly before turning on
the air conditioner.
Let hot air out first
If the excavator has been parked in the sun,
open the windows or door to let the hot air
out of the cab before using the air conditioner.
Caution on refrigerant (gas)
Exposure of the eyes or hands to the cooler’s
refrigerant could result in blindness or
frostbite. Never touch the refrigerant or
loosen the parts of the cooling circuit.
Should the refrigerant gas leak, keep flames
away.
