Diesel Fuel Specifications

In general, diesel fuels are blended to satisfy the low air temperature requirements of the geographical area in which they are sold.

Diesel fuel is usually specified to ASTM D975 and sold as either Grade 1 for cold air temperatures or Grade 2 for warm air temperatures.

If diesel fuels being supplied in your area DO NOT meet any of the above specifications, use diesel fuels with the following equivalent properties:

· Cetane Number 40 (minimum). A cetane number greater than 50 is preferred, especially for air temperatures below -20°C (-4°F) or elevations above 1500 m (5000 ft).

· Cold Filter Plugging Point (CFPP). The temperature at which diesel fuel begins to cloud or jell. Use diesel fuels with a CFPP which is at least 5°C (9°F) below the expected low air temperature.

· Sulfur Content of 0.05% (maximum). Diesel fuels for highway use in the United States now require sulfur content to be less than 0.05%. If diesel fuel being used has a sulfur content greater than 0.5%, reduce the service interval for engine oil and filter by 50%.

Bio-Diesel Fuels with bio-degradable properties that meet specification DIN 51606 or equivalent may be used.

Consult your local diesel fuel distributor for properties of the diesel fuel available in your area.

c CAUTION: Avoid injury! California Proposition 65 Warning: Diesel engine exhaust and some of its elements from this product are known to the State of California to cause cancer, birth defects, or other reproductive harm.

Lubricity

Diesel fuel must have adequate lubricity to ensure proper operation and durability of fuel injection system components. Fuel lubricity should pass a minimum of 3300 gram load level as measured by the BOCLE scuffing test.

Avoid Damage to Plastic and Painted Surfaces

· Insect repellent spray may damage plastic and painted surfaces. Do not spray insect repellent near machine.

· Be careful not to spill fuel on machine. Fuel may damage surface. Wipe up spilled fuel immediately.

· Do not wipe dry surface with dry cloth. Plastic and painted surfaces may scratch.

Fuel Storage


IMPORTANT: Avoid damage! DO NOT USE GALVANIZED CONTAINERS-diesel fuel stored in galvanized containers reacts with zinc coating in the container to form zinc flakes. If fuel contains water, a zinc gel will also form. The gel and flakes will quickly plug fuel filters and damage fuel injectors and fuel pumps.

It is recommended that diesel fuel be stored ONLY in a clean, approved POLYETHYLENE PLASTIC container WITHOUT any metal screen or filter. This will help prevent any accidental sparks from occurring. Store fuel in an area that is well ventilated to prevent possible igniting of fumes by an open flame or spark. This includes any appliance with a pilot light.


IMPORTANT: Avoid damage! Keep all dirt, scale, water or other foreign material out of fuel.

Keep fuel in a safe, protected area and in a clean, properly marked ("DIESEL FUEL") container. DO NOT use de-icers to attempt to remove water from fuel. DO NOT use de-icers to attempt to remove water from fuel. DO NOT depend on fuel filters to remove water from fuel. It is recommended that a water separator be installed in the storage tank outlet. BE SURE to properly discard unstable or contaminated diesel fuel and/or their containers when necessary.

Filling the Fuel Tank

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

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 funnel, make sure it is plastic. Avoid using a funnel which has a metal screen or filter.

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

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


IMPORTANT: Avoid damage! Avoid spilling fuel. Fuel can damage plastic and painted surfaces. Fuel tank capacity is approximately 24 L (6.3 gal).

1. Remove fuel tank cap (A).

M97667

2. Fill fuel tank at end of each day's operation to prevent condensation in fuel tank as moist air cools.

3. Fill fuel tank when fuel gauge shows 1/4 or less fuel in tank.

4. Install fuel tank cap.

Changing Rear Tread

To provide best stability, operate tractor with rear wheels mounted in the wide tread position whenever possible.

M99215

c CAUTION: Avoid injury! Support tractor securely on stands before removing a wheel.


IMPORTANT: Avoid damage! Always make sure tires rotate in proper direction. Arrows on sidewall should point in direction of forward rotation.

· Move wheel from one side of tractor to the other (A) to maintain proper direction of tire rotation.

· Tighten tractor front wheel lug bolts to 133 N·m (98 lb-ft). Tighten tractor rear wheel lug bolts to 186 N·m (137 lb-ft). Check and retighten bolts as instructed in service section.

Service Tires Safely

Explosive separation of a tire and rim parts can cause serious injury or death.

DO NOT attempt to mount a tire unless you have the proper equipment and experience to perform the job.

Always maintain the correct tire pressure. Do not inflate the tire 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 an extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available.

Check wheels for low pressure, cuts, bubbles, damaged rims or mission lug bolts and nuts.

Checking Wheel Bolt Torque

c CAUTION: Avoid injury! To avoid injury from possible tractor roll over, NEVER operate tractor with a loose rim, hub, or axle.

Anytime hardware is loosened, it MUST be retightened to specified torque:

1. Tighten FRONT wheel bolts to 133 N·m (98 lb-ft).

2. Tighten REAR wheel bolts to 186 N·m (137 lb-ft).

NOTE: Follow checking procedure when a new tractor is first used, or when wheels have been removed.

· After driving tractor about 100 m (109 yds.), and before placing it under load, retighten hardware to specified torque.

· Check hardware after operating tractor for 3 hours and again after 10 hours.

· Check all hardware frequently and keep it tight.
