Checking Tire Pressure

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

ˇ Do not attempt to mount a tire without the proper equipment and experience to perform the job.

ˇ 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.

ˇ 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.

ˇ 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:

Checking Tightness of Wheel Bolts


M39810

Check wheel bolts often during the first 100 hours of operation. Tighten every other bolt in sequence until all bolts are at 88 Nˇm (65 lb-ft).

Raising Hood


M71489

1. Lift front of hood up.


M71490

2. Raise back of hood.

Removing Grille

1. Lift front of hood up. DO NOT raise hood all the way up.


M71491

2. Open and turn the two spring-loaded fasteners (A) to the horizontal position.

3. Pull grille (B) forward.

4. Remove grille.

Removing and Cleaning Side Panels

1. Raise hood.


M71492

2. Open and turn two spring-loaded fasteners (A) to the horizontal position.

IMPORTANT: Avoid damage! Do not remove screen from side panel, you will damage the screen tabs.


3. Remove side panel.

IMPORTANT: Avoid damage! Be sure air intake hose is properly installed in left-hand side panel.



M71541

4. Hold side panel in an upright position and clean using compressed air or water. Be sure large air intake hole (B) is facing down so dirt and debris can be forced out of panel.

5. Install side panels.

Refueling Machine

c CAUTION: Avoid injury! Handle fuel with care, it is highly flammable:

ˇ DO NOT refuel machine while you smoke, when machine is near an open flame or sparks, or when engine is running.

ˇ STOP engine.

ˇ Fill fuel tank outdoors.

ˇ Prevent fires: clean oil, grease and dirt from machine. Clean up spilled fuel immediately.

ˇ Do not store machine with fuel in tank in a building where fumes may reach an open flame or spark.

ˇ To prevent fire and explosion caused by static electric discharge, while you fill tank, use a non-metal fuel container. If you use a funnel, MAKE SURE it is PLASTIC. Avoid using a funnel which has a metal screen or filter.

ˇ Use only clean oil and fuel and clean approved containers and funnels.

ˇ Store oil and fuel in an area protected from dust, moisture and other contamination.

Fuel

IMPORTANT: Avoid damage! Avoid spilling fuel. Fuel can damage plastic and painted surfaces.

DO NOT mix oil with gasoline. Unleaded gasoline with an octane rating of 87 or higher is recommended.

Fuel tank capacity is 24.6 L (6.5 gal).


ˇ Use only clean, fresh, UNLEADED REGULAR grade gasoline.

ˇ Remove any trash from top of fuel tank drain area.

ˇ Never use fuel that is stale or has been stored for a long period of time:

Warm Weather: Maximum 60 days.

Cold Weather: Maximum of 90 days.

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

Oxygenated Fuel

Oxygenates (either ethanol or MTBE) are added to the gasoline. If you use the oxygenated fuel be sure it is unleaded and meets the minimum octane rating requirement.

The following are the EPA approved percentages of fuel oxygenates:

ETHANOL (Ethyl or Grain Alcohol): You may use gasoline containing up to 10 percent ethanol by volume.

MTBE (Methyl Tertiary Butyl Ether): You may use gasoline containing up to 15 percent MTBE by volume.

METHANOL (Methyl or Wood Alcohol): You may use gasoline containing up to 5 percent methanol by volume, as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5 percent methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of your fuel system.

Filling Fuel Tank

IMPORTANT: Avoid damage! To avoid fuel pump damage, be sure key is in STOP (Off) position.


Fill fuel tank at the end of each day's operation. This will help prevent condensation and freezing during cold weather.

1. STOP engine. If engine is hot let it cool several minutes before you add fuel.


M71486

2. Remove fuel tank cap (A) slowly to allow any pressure built up in tank to escape.

3. Fill tank only to bottom of filler neck. Approximate fuel tank capacity is 24.6 L (6.5 gal.).

4. Install fuel tank cap.

Cleaning and Repairing Plastic Surfaces

Your John Deere dealer has the professional materials needed to properly remove surface scratches from any plastic surfaces, do not attempt to paint over marks or scratches in plastic parts.

IMPORTANT: Avoid damage! Improper care of machine plastic surfaces can damage that surface:

ˇ DO NOT wipe plastic surfaces when they are dry. Dry wiping will result in minor surface scratches.

ˇ Use a soft, clean cloth (bath towel, diaper, automotive mitt).

ˇ DO NOT use abrasive materials, such as polishing compounds, on plastic surfaces.

ˇ DO NOT spray insect repellent near machine.


1. Rinse hood and entire machine with clean water to remove dirt and dust that may scratch the surface.

2. Wash surface with clean water and a mild liquid automotive washing soap.

3. Dry thoroughly to avoid water spots.

4. Wax the surface with a liquid automotive wax. Use products that specifically say "contains no abrasives."

IMPORTANT: Avoid damage! Do not use a power buffer to remove wax.


5. Buff applied wax by hand using a clean, soft cloth.

Cleaning and Repairing Metal Surfaces

Cleaning:

Follow automotive practices to care for your vehicle painted metal surfaces. Use a high-quality automotive wax regularly to maintain the factory look of your vehicle's painted surfaces.

Repairing Minor Scratches (surface scratch):

1. Clean area to be repaired thoroughly.

IMPORTANT: Avoid damage! DO NOT use rubbing compound on painted surfaces.


2. Use automotive polishing compound to remove surface scratches.

3. Apply wax to entire surface.

Repairing Deep Scratches (bare metal or primer showing):

1. Clean area to be repaired with rubbing alcohol or mineral spirits.

2. Use paint stick with factory-matched colors available from your John Deere dealer to fill scratches. Follow directions included on paint stick for use and for drying.

3. Smooth out surface using an automotive polishing compound. Do not use power buffer.

4. Apply wax to surface.
