EXPLANATION OF COMPONENTS
INSPECTION AND MAINTENANCE
Even when not using the air conditioner, run the compressor at low speed for several minutes once a week to
prevent the loss of the oil film at various parts of the compressor. (Run the engine at low speed and set the
temperature control lever to the central position.)
Clean the air filter and check the refrigerant. For details, see "CLEAN AIR CONDITIONER AIR FILTER (PAGE
4-24)" and "CHECK REFRIGERANT (GAS) LEVEL (PAGE 4-25)".
To enable the air conditioner to perform to the full and to maintain a pleasant working environment, always contact
your Komatsu distributor to have the air conditioner refilled with refrigerant and to carry out other checks.
