Komatsu HD465-8 User Manual

(A) No bubbles in refrigerant flow: Suitable
(B) Some bubbles in refrigerant flow: Insufficient (bubbles pass
continuously)
(C) Colorless, transparent: No refrigerant
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.
