TEST THE LEVEL OF REFRIGERANT FOR AIR CONDITIONER (GAS)

k

k

WARNING

• Never touch the refrigerant.

Do not loosen any part of the refrigerant circuit.
If the refrigerant used in the air conditioner gets into your eyes or is splashed on your hands, it may
cause loss of sight or frostbite.

• Do not bring any open flame close to any point where the refrigerant (gas) is leaking.

If the level of the refrigerant (gas) is low, the cooling effect will be reduced. Perform the check while running the
engine at high idle and operating the air conditioner at high speed.
Check the condition of the refrigerant gas (Hydrofluorocarbons
HFC-134a) that circulates the refrigerant circuit, through the
sight glass (1) (inspection window) of the receiver.

(A) Proper

No bubbles in refrigerant flow

(B) Insufficient

Some bubbles in refrigerant flow (bubbles pass continuously)

(C) None

Transparent with no color

REMARK

When there are bubbles, the refrigerant (gas) level is low, so ask your Komatsu distributor to add refrigerant. If
the air conditioner continues to run with low refrigerant (gas) level, it will cause damage to the compressor.
