3.Push down on the PTO switch to the “disengage” position.

Note: It is not necessary for the operator to be in the seat to start the engine.

4.Place the throttle midway between the “SLOW” and “FAST” positions.

5.On a cold engine, push the choke lever forward into the “ON” position.

On a warm engine, leave the choke in the “OFF” position.

6.Turn ignition switch to the “START” position. Release the switch as soon as the engine starts.

Important: Do Not crank the engine continuously for more than ten seconds at a time. If the engine does not start, allow a 60 second cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motor.

7.If the choke is in the “ON” position, gradually return choke to the “OFF” position as the engine warms up.
