Operation

that the rear part of the seat is secured with the seat latch.

Open the Fuel Valve

1.Slowly open the fuel valve to equalize the pressure in the tank. The fuel valve is located on the top end of the LPG tank. If the fuel valve is opened too quickly, the pressure relief valve is equipped with a back pressure check valve that will shut off the fuel supply. If this happens, close the fuel valve completely and wait five seconds. Slowly open the fuel valve.

2.Rotate the fuel valve counterclockwise to turn on the fuel. If leaks are detected, refer to the leak information in the Inspection section in Safety.

Starting the Engine

1.Move the motion control levers out to the neutral lock position.

2.Pull up and back on the parking brake lever to engage the parking brake.

3.Push in on the PTO switch to the “STOP” position.

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

4.Place the throttle in the “SLOW” position.

5.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.

Engaging the PTO

DANGER

The rotating blades under the mower deck are dangerous. Blade contact can cause serious injury or kill you.

Do Not put hands or feet under the mower or mower deck when the blades are engaged.

DANGER

An uncovered discharge opening will allow objects to be thrown in an operator’s or bystander’s direction. Also, contact with the blade could occur. Thrown objects or blade contact can cause serious injury or death.

Never operate the mower with the discharge deflector raised, removed, or altered unless there is a grass collection system or mulch kit in place and working properly.

The PTO push-pull switch engages the cutting blades. Be sure that all persons are clear of the mower deck and discharge area before engaging PTO.

Important: Operator must be in seat before the PTO can be engaged.

1.Set the throttle midway between the “SLOW” and “FAST” positions.

2.Pull the PTO switch outward to engage the blades.

3.Place the throttle in the “FAST” position to begin mowing.

Disengaging the PTO

1.Set the throttle midway between the “SLOW” and “FAST” positions.

2.Push the PTO switch in to disengage the blades.

Stopping the Engine

1.Bring the unit to a full stop.

2.Disengage the PTO.

3.Move the motion control levers out to the neutral lock position.

4.Engage the parking brake.

5.Place the throttle in the “SLOW” position.

6.Turn off the fuel valve and allow the engine to run out of fuel. Failure to do this may cause the engine to “flood” when re-starting.

7.Turn the ignition switch to the “OFF” position once the engine has stopped.

8.Remove the key to prevent children or other unauthorized persons from starting engine.
