Check and Adjust the Governor
Lever and Engine Speed Control
The governor lever and engine speed control
(accelerator lever, pedal, etc.) of the machine are
connected together by an accelerator cable or
rod. If the cable becomes stretched, or the
connections loosen, the governor lever may not
respond to change of engine speed control
position. This may make operation of the machine
unsafe. Check the cable periodically and adjust if
necessary. Consult your authorized Yanmar
industrial engine dealer or distributor for the
adjustment procedure.
NEVER force the accelerator cable or pedal to
move. This may deform the governor lever or
stretch the cable and cause irregular operation of
the engine speed control.
Checking and adjusting the governor lever:
1. Check that the governor lever (Figure 11, (1))
makes uniform contact with the high idle
(Figure 11, (2)) and low idle (Figure 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 accelerator cable.
3. In some engine speed control applications,
loosen the accelerator cable locknut
(Figure 11, (4)) and adjust the cable so the
governor lever makes proper contact with the
high / low idle speed limit screw.

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.
