Operation Operation position. Do Not run a warm engine with choke in the “ON” position. Note: Determine the left and right sides of the machine from the normal operating position. Controls Motion Control Levers The motion control levers located on each side of the console control the forward and reverse motion of the machine. Moving the levers forward or backward turns the wheel on the same side forward or reverse respectively. Wheel speed is proportional to the amount the lever is moved.
Operation The ignition switch is used to start and stop the engine. The switch has three positions “OFF”, “ON” and “START”. Insert key into switch and rotate clockwise to the “ON” position. Rotate clockwise to the next position to engage the starter (key must be held against spring pressure in this position). Allow the key to return to the “on” position immediately after the engine starts.
Operation The LCD indicator will appear when the PTO switch is disengaged (see Figure 8). Deck Lift Pedal Located at the right front corner of the floor pan (see Figure 10). Push the pedal forward with your foot to raise the cutting deck. Allow the pedal to move rearward to lower the cutting deck to the cut height that has been set. Figure 9 1. 2. 3. 4. 5. 6. 7.
Operation than 10% ethanol, premium gasoline, or white gas because the fuel system could be damaged. 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 (if equipped). Make sure you understand the controls, their locations, their functions, and their safety requirements.
Operation Open the Fuel Shut-Off Valve DANGER The fuel shut off valve is located behind and below the seat. Rotate the valve and align with the fuel line to open. 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. Starting the Engine 1. Move the motion control levers out to the neutral lock position.
Operation Driving the Machine Driving Forward 1. Release the parking brake. 2. Move the motion control levers inward to the center to the neutral position. 3.
