3.5.5 AIR CONDITIONER (if provided)
DANGER
•
The coolant contained in the air conditioning system is very dangerous. If some sprays should get into
the eyes or come in contact with the skin, immediately wash with plenty of water and consult a doctor. To
avoid possible explosions, do not cause sparks and do not use naked flames near the system.
•
The coolant contained in the air conditioning system is considered special waste and must be recovered
and disposed of according to the antipollution regulations in force.
•
For specific maintenance operations to be carried out on the air conditioning system, contact your Ko-
matsu Utility Dealer. Non-compliance with this advice may cause serious damage and even death.
The ventilation and cooling of the cab serve to reduce the opera-
tor’s stress when the outside temperature is particularly high.
Ventilation and air change are achieved by means of a three-
speed fan integrated in the air conditioning unit and installed in-
side the cab, behind the seat. The ventilation intensity is adjusted
through the switch (2) positioned on the left console
The ventilation and cooling system requires air suction from both
inside and outside the cab.
Air suction from the outside is protected by a filter positioned on
the right side of the cab, while inside air suction (recirculation) is
protected by a filter positioned on the air conditioning unit.
The recirculation of inside air ensures more rapid cooling and is
very useful when the machine is operated in conditions of ex-
treme pollution (tunnels, very dusty places, small or closed plac-
es, etc.). The recirculation of air is obtained by turning the
handwheel (4) positioned on the rear right side of the cab console
completely clockwise.
