Pre-Start

Fill fuel tank on level ground. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher.

Important: Never use methanol, gasoline containing methanol, gasohol containing more 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.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.

Operating Instructions

Raise the Rollover Protection System (ROPS)

Important: The roll bar is an integral and effective safety device. Keep the roll bar in the raised and locked position when operating the mower. Lower the roll bar temporarily only when absolutely necessary.

1.The knob must be completely latched with the tabs interlocking as shown in Figure 12 to lock the roll bar in the raised, operate position.

2.Apply forward pressure to the upper hoop of the roll bar.

3.Pull the knob and rotate 90° to hold in the unlatched position to lower the roll bar.

4.To return to the operate position, raise the roll bar, and then rotate knobs 90° so that the tabs interlock partially. Apply forward pressure to the roll bar upper hoop and observe that the knobs return to the completely latched position.
