Electronic Control Unit Malfunction
Indicator
Kohler EFI Units Only:
The electronic control unit (ECU) continuously
monitors operation of the EFI system. If a problem
or fault within the system is detected, the malfunction
indicator light (MIL) is illuminated. The MIL is the
light located in the right console panel to the right of
the throttle control. Follow the troubleshooting steps
outlined in the Kohler engine operator’s manual if the
MIL is illuminated.
Pre-Start
Fill fuel tanks. See Fuel Recommendations in
the Specifications section for additional gasoline
information.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Fill the fuel tank to the
bottom of the filler neck. The empty space in the
tank allows gasoline to expand. Overfilling may result
in fuel leakage or damage to the engine or emission
system.

locations, their functions, and their safety
requirements.
Refer to the Maintenance section and perform all the
necessary inspection and maintenance steps.
