Periodic Maintenance Procedures
Checking and adjusting the governor lever:
1. Check that the governor lever (Figure 5-11, (1))
makes uniform contact with the high idle
(Figure 5-11, (2)) and low idle
(Figure 5-11, (3)) speed limit screws when the
engine speed control is in the high idle speed or
low idle speed position.

2. If the governor lever does not make contact with
the high idle or low idle speed limit screw, adjust
the throttle cable.
3. In some engine speed control applications,
loosen the throttle cable lock nut
(Figure 5-11, (4)) and adjust the cable so the
governor lever makes proper contact with the
high / low idle speed limit screw.
CAUTION
NEVER attempt to adjust the low or high
idle speed limit screw. This may impair
the safety and performance of the
machine and shorten its life. If the idle
speed limit screws require adjustment,
see your authorized Yanmar industrial
engine dealer or distributor.
