REMEDY
Replace valve.
(9)
Check voltage. Replace pilot valve assembly.
(6)
Replace pilot valve assembly.
(7)
Adjust pressure so that pilot pressure will fall within operating pressure range during opretation.
(8)
-If worng oil used, completely air blow to remove oil and replace valve. After valve is replaced,
use turbine oil class 1 (ISO VG32).
No. Remedy
(2)
Re-wire correctly.
(1)
