GUARDS, CAB AND DRIVER'S SEAT
3.5.4 AIR CONDITIONER (if installed)
The coolant used in the air conditioning system is very dangerous. If it is sprayed into the eyes or in
q
case of contact with the skin, wash with plenty of water and consult a doctor without delay. Furthermore,
to avoid any explosion, do not generate sparks and do not use naked flames near the air conditioner.
The coolant contained in the air conditioning system is considered special waste and must be collected
q
and disposed of according to the antipollution regulations in force.
For specific maintenance operations to be performed on the air conditioning system, contact your
q
Komatsu Dealer. Non-compliance with these instructions may cause serious damage and even death.
The cab ventilation and cooling functions have the specific
purpose to reduce the operator's stress when the outside
temperature is particularly high.
Ventilation and air change are achieved by means of a 3-speed
fan which is built in the air conditioning system and assembled on
the outside of the machine, under the cab. The ventilation can be
adjusted via the selector (2).
The ventilation and cooling system ensures air suction both from
the outside and the inside of the cab.
Air suction from the outside is protected by means of a filter
positioned on the right side of the cab, while air suction from the
inside (recirculation) is protected by means of an internal filter (5)
positioned
on
the
compartment.
The internal air recirculation ensures quicker cooling and is very
useful when working in areas where air pollution is considerable
(tunnels, dusty places, small or badly ventilated rooms, etc.). Air
recirculation is obtained by rotating the knob (4) completely
clockwise.
NOTE
Do not use the air recirculation function too long in rainy or cold
q
days, since this would increase the fogging of the inside of the
windows.
