INSPECTION

PROCEDURE

1. INSPECT NO. 2 MAGNET VALVE ASSEMBLY

(a) Apply auxiliary battery voltage to the terminals of the connector, and check the No. 2 magnet valve assembly operates. OK: Auxiliary Battery Connection Specified Condition Auxiliary battery positive ( ) → 2 (VD) Auxiliary battery negative (-) → 1 (DHMV) Apply compressed air to the air inlet and check that air not comes out from the air outlet. If the result is not as specified, replace the No. 2 magnet valve assembly.
