Fuel

SERVICE MISCELLANEOUS

CAUTION: Handle fuel with care, it is highly flammable and can cause serious injury or death:

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

- Fill fuel tank outdoors.

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

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

- 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.

- Use only clean approved containers and funnels.

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

- DO NOT use METHANOL gasoline. METHANOL is harmful to the envir onment and to your health.

IMPORTANT: 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.

Using Clean Fuels

Dirt in the fuel system is a major cause of performance problems. Be sure to clean any grass or trash from the top of the tank before removing lid. Use of a PLASTIC funnel with a plastic mesh strainer when filling the tank will prev ent most foreign material from entering the tank.

Service Miscellaneous - Page 62

SERVICE MISCELLANEOUS

Octane Rating

Regular grade 87 octane unleaded fuel is recommended for use in your tractor. Higher octane fuels will seldom make your tractor perf orm better . If your tractor de ve lops a starting or performance problem immediately after use of new fuel, change supplier or fuel brand. If the prob lem still exists after switching fuel, see your John Deere dealer for service.

Fuel Blends

Fuels are blended to give peak performance during cold weather and warm weather. For cold weather, gasoline is specially blended to provide better starting capabilities. However, avoid prolonged storage of coldweather blended fuel because it will evaporate more quickly. You may experience longer cranking times in cold weather with “old” fuel. Buy smaller amounts of cold-weather blended fuel in winter.

Fuels used during the summer are not required to provide improved starting properties so they are blended differently. As a result, you may experience hard starting or other performance problems during cold weather if you use fuel remaining from summer uses.

Oxygenated or Reformulated Fuels

Many areas are now required to add “oxygenates” (either alcohol or ether) which blend oxygen into the fuel to help reduce exhaust emissions. If you use oxygenated fuel be sure it is unleaded and meets the minimum octane rating requirement. DO NOT use fuel that contains methanol to avoid producing excess emissions.

Although fuels blended with alcohol or ether allow your engine to run cleaner, they may contribute to fuel system damage and performance problems by causing gum and varnish deposits, especially if fuel is stored for several weeks or more.

Using clean, fresh fuel will help to prevent damage to the fuel system and will help maintain peak engine performance. If engine performance problems occur, use fuel from another supplier before suspecting machine problems. Suppliers blend fuels differently and changing suppliers will generally solve any perf ormance problems.

Service Miscellaneous - Page 63

SERVICE MISCELLANEOUS

M88554

Using Fresh Fuel and Stabilizers

The best thing you can do to ensure peak performance of your engine is to use “fresh” fuel. Your tractor’s engine will perform well with most good-quality fresh fuels regardless of additives. An y fuel will begin to deteriorate and evaporate over time and begin to form gum and varnish deposits in the fuel system. Help to avoid this b y buying only enough fuel to last approximately 30 da ys or add fuel stabilizer immediately.

Adding a fuel stabilizer to the fuel system is recommended any time the tractor will not be operated for more than 60 days. Varnish deposits may build up in the carburetor in as little as a few weeks by using stale, oxygenated fuel.

No stabilizer will work with “stale” fuel, any fuel that is more than 30 days old. (See

For Storage

in this section for information on adding

stabilizer to the fuel.)

Preparing Your Engine

Filling Fuel Tank

IMPORTANT: Dir t and water in fuel are major causes of engine performance problems. Prevent dirt and debris from entering the fuel tank when filling.

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

Fuel tank capacity: GEAR MODELS, 1842GV and 1848GV: 13 L (3.5 gal) AUTOMATIC MODELS, 1842HV and 1848HV: 11 L

(3.0 gal)

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

2. Remove grass clippings and other trash from tank area.

3. Lift seat and remove fuel tank cap (A).

4. Fill tank with fresh fuel only to bottom of filler neck.

5. Install fuel tank cap and lower seat.

Care for Plastic and Painted Surfaces

PLASTIC SURFACES

The plastic parts on your tractor are made of a blend of polycarbonate and polyester materials. These parts are extremely strong and durable. Unlike painted metal, the plastic parts will never dent or rust. If the plastic parts get scratched, the color will remain the same since the color goes through the entire part.

IMPORTANT: “Dry wiping” or wiping the plastic surface when it is dry will result in minor surface scratches. Always wet the surface before cleaning. Follow correct cleaning and waxing procedures.

Correct Cleaning Care:

NOTE: Follow cleaning pr ocedure every time plastic surfaces are cleaned. DO NOT wipe dry plastic surface with hand or towel.

1. Before washing, rinse hood and entire machine with clean water to remove dirt and dust that may scratch the surface.

2. Wash plastic surface with clean water and a mild liquid automotive washing soap. Use a SOFT, CLEAN cloth (bath towel or automotive mitt) when washing.

3. Dry thoroughly with a SOFT, CLEAN cloth (diaper or bath towel).

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

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

Service Miscellaneous - Page 66

SERVICE MISCELLANEOUS

Avoid Damage:

• “Dry wiping” or wiping the plastic surface when it is dry is a major source of minor surface scratches.

• DO NOT wipe hood or other plastic parts unless wetted first.

• DO NOT apply wax unless plastic surface has been thoroughly cleaned first.

• DO NOT use abrasive materials, such as polishing compounds, to clean or to wax plastic surface.

• DO NOT wax plastic surfaces without drying first. Hard-to-remove water spots will be left.

• DO NOT use solvents or commercial cleaners.

• DO NOT use power buffers to remove wax.

• DO NOT spray insect repellent near machine. Insect repellent spray may damage plastic or painted surfaces.

STORING MACHINE

Preparing Engine For Storage

NOTE: Properly preparing your tractor engine for storage will make it easier to start the following season. Engine storage procedure should be used if vehicle is not used for longer than 60 days.

There are two satisfactory methods of preparing the engine for storage: running the engine completely dry of fuel, or filling the fuel tank with a mixture of fresh fuel and fuel stabilizer.

Running engine dry of fuel:

NOTE: Try to anticipate the last time the tractor will be used for the season so very little fuel is left in the fuel tank.

1. Park tractor in a well-ventilated area.

2. Engage park brake and disengage PTO.

3. Turn on engine and allow to run until it runs out of fuel.

4. Turn key to OFF position.

5. Continue with Prepar ing Engine.

Add fuel and stabilizer mixture to tank:

1. Park tractor in a well-ventilated area.

IMPORTANT: Be sure fuel is fresh when adding fuel stabilizer. Fuel stabilizers are ineffective when added to fuels that are more than 30 days old.

2. Mix fresh fuel and fuel stabilizer in separate container. Follow stabilizer instructions for mixing.

NOTE: Filling the fuel tank reduces the amount of air in the fuel tank and helps reduce deterioration of fuel.

3. Fill fuel tank with stabilized fuel.

4. Run engine for a few minutes to allow fuel mixture to circulate through carburetor.

5. Continue with Prepar ing Engine.
