start a reverse rotation. A flashing reverse light on the instrument
panel will indicate that the machine is in reverse.

Tip: The maximum engine RPM will be 6000 when in reverse.

restarted.
Disengaging Reverse

Altitude Setting

At higher altitudes (above 6000 feet), the engine will require a different
ignition setting to improve the success of the reverse system. To set for a
higher altitude, start the engine and hold the button down until the light
on the instrument panel flashes rapidly, then release the button.
To set the reverse for lower elevations, continue holding the button
down until the reverse indicator light blinks slowly. Once set, it's stored
in memory until changed, whether the machine is running or not.
