WARNING
If the refrigerant used in the air conditioner gets into your eyes or on your hands, it may cause loss of
sight or frostbite. Do not touch the refrigerant. Never loosen any part of the refrigerant circuit.
Do not bring any flame close to any point where the refrigerant gas is leaking.
If there is a lack of refrigerant (Freon 134a), the cooling perfor-
mance will be poor. When the engine is running at full throttle
and the cooler is running at high speed, look at the sight glass
(1) (inspection window) in the refrigerant hose fitting to check
the condition of the refrigerant gas (Freon 134a) flowing in the
refrigerant circuit.?
(A) No bubbles in refrigerant flow: Suitable
(B) Some bubbles in flow (bubbles pass continuously):
Lack of refrigerant
(C) Colourless, transparent: No refrigerant
REMARK
When there are bubbles, the refrigerant gas level is low, so
contact your Komatsu distributor to have refrigerant added. If
the air conditioner is run with the refrigerant gas level low, it will
cause damage to the compressor.
INSPECTION DURING OFF SEASON
Inspection During Off Season:ALL-K500-20DK00A
Even during the off-season, operate the air conditioner for three to five minutes once a month to maintain the oil
film at all parts of the compressor.
