Filling Fuel Tank

Use regular grade 87 octane unleaded fuel.

Add John Deere fuel stabilizer to fuel before using it in your machine to prevent engine damage due to stale fuel. Follow directions on stabilizer container.

c CAUTION: Avoid injury! Fuel vapors are explosive and flammable:

· Shut engine off before filling fuel tank.

· Do not smoke while handling fuel.

· Keep fuel away from flames or sparks

· Fill fuel tank outdoors or in well ventilated area.

· Clean up spilled fuel immediately.

· Use clean approved non-metal container to prevent static electric discharge.

· Use clean approved plastic funnel without screen or filter to prevent static electric discharge.

IMPORTANT: Avoid damage! Dirt and water in fuel can cause engine damage:

· Clean dirt and debris from the fuel tank opening.

· Use clean, fresh, stabilized fuel.

· Fill the fuel tank at the end of each day's operation to keep condensation out of the fuel tank.

· Use a non-metallic funnel with a plastic mesh strainer when filling the fuel tank or container.


NOTE: Capacity of fuel tank is 34 L (9 gal).

1. Stop engine, let it cool several minutes before adding fuel.

2. Remove any grass or debris from top of fuel tank.

Checking Tire Pressure


MIF

c CAUTION: Avoid injury! Explosive separation of a tire and rim parts can cause serious injury or death:

· DO NOT attempt to mount a tire without the proper equipment and experience to perform the job.

· Always maintain the correct tire pressure. DO NOT inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel.

· When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly.

· Check tires for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.

1. Check tires for damage.

2. Check tire pressure with an accurate gauge.

3. Add air, if necessary:
