0000001501 LEVER
1. (1) Remove the link (A) (B) from (C) and (D).
(2)In this condition, perform normal governor adjustment.
2. (1) Mount the link.
(2)Adjust the umbrella lever.
(3)Adjust the dead point.
Loosen the screw E.
Measure the lever angle when the pump speed is N and the rack position is R.
Temporarily fix the lever with the idle stopper bolt at that angle.
Set the lever (I) with bolts (G) and (H) so that a dead point is obtained.
Check play at the sliding part (J).
Loosen the idle stopper bolt.
Slide the lever.
Re-set the idle stopper bolt at the position of the dead point at that time.
At this time, confirm N, R.
Set so that screw E contacts the lever K.
Fix with the lock nut (F).
3.(1) Set the idle setting.
