0000001501 GOVERNOR IDLE SUB SPRING
f : Installation load ON
2 stage idle sub-spring simultaneous setting method
1. (1) Remove the idling sub spring capsule from the governor.
(2)Tighten the screw (A) until it contacts the spring (B) (that is, until the set force is generated).
(3)Return to speed N1.
(4)Set so that the set force is zero.
(5)Fix using the lock nut (C).
2. Set the idle sub spring capsule adjusted as per (1) 1.
(2)Same as the normal 1 stage idle sub spring.
(3)Set so that it satisfies the governor adjustment standards.
(4)Do not loosen lock nut (C) at this time.
