Checking Tire Pressure

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.


M33418

2. Check tire pressure with an accurate gauge.

3. Adjust air pressure, if necessary:

Tire Size

Pressure

kPa (psi) (bar)

20 x 10 - 8

82.7 (12) (.827)

20 x 10 -10

151.7 (22) (1.50)


Refueling Machine

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 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 oil and fuel and clean approved containers and funnels.

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

Fuel

· Use Grade No. 2-D fuel at temperatures above 4°C (40°F).

· Use Grade No. 1-D fuel at temperatures below 4°C (40°F).

· Use Grade No. 1-D fuel for all air temperatures at altitudes above 1500 m (5000 ft.).

· For maximum filter life, sediment and water should not be more than 0.10 per cent.

· The cetane number should be 45 minimum. If you operate your machine where air temperatures are normally low or in high altitudes, you may need fuel with a higher cetane number.

· Cloud Point - For cold weather operation, cloud point should be 6°C (10°F) below lowest normal air temperature.

· In winter use special winter fuel or add an anti-gelling compound to fuel to maintain its proper viscosity.

IMPORTANT: Avoid damage! Diesel fuels stored for a long time may form gum and plug filters.

Diesel fuel stored in galvanized containers reacts with zinc coating on container to form zinc flakes. If fuel contains water, a zinc gel will form. Gel and flakes will quickly plug fuel filters and damage fuel injectors and pumps.


Diesel Fuel Storage:

DO NOT use a galvanized container to store diesel fuel.

Store fuel in:

· Plastic containers.

· Aluminum containers.

· Specially coated steel containers made for diesel fuel.

DO NOT use brass-coated containers, brass is an alloy of copper and zinc.

Filling Fuel Tank

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

Fuel tank capacity is 28 L (7.4 Gal).

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

2. Remove any trash from area around fuel tank.

3. Remove fuel tank cap slowly to allow any pressure built up in tank to escape.

4. Fill tank only to "FULL" line.

5. Install fuel tank cap.

Tighten Wheel Bolts


M56242

NOTE: Tighten wheel bolts after first 10 hours of operation and every 50 hours thereafter.

Tighten wheel bolts to 40734 N·m (30025 lb-ft.).

Raising Hood

c CAUTION: Avoid injury! Carefully raise and lower hood to avoid pinching hands.

1. Stop the engine.

2. Engage the parking brake.


M87064

3. Turn button (A) to unlock hood and pull hood up.

NOTE: Hinged cover plates (C) on each side of hood, tilt forward independently to provide additional access and service capability.


M87064

4. Lift off air plenum (B) to expose the top of engine.

Adjusting Parking Brake


M79100

1. To adjust park brake tension, place park brake (A) in the DISENGAGED position.


M79109

2. Tighten the yoke (B) so the brake pads just begin to drag on the brake rotor. Then back off one revolution.

3. When all yoke adjustments have been used, back off the yoke so the threads on the rod (C) are flush with the yoke.

IMPORTANT: Avoid damage! Do not loosen top nut (G) until spring is loose. If top nut is backed off too far, spacer on inside of spring may jump out of hole in spring bracket and bind up brake when top nut is tightened.



M79108

4. Loosen top nut (G) approximately 1/4 inch.

5. Remove hairpin clip from end of "J" rod (E).

6. While holding caliper arm with spring assembly, up as far as possible adjust "J" rod until end of rod aligns with hole in brake lever arm (F).

7. Reassemble "J" rod, washer, and hairpin clip (E).

8. Tighten top nut (G), while holding bottom nut (D), until it contacts spacer. Torque to 10 N·m (7 lb-ft).

9. Engage the brake and repeat on opposite side.

Cleaning Equipment Properly After Use

Following are general guidelines for the daily cleaning of John Deere Golf & Turf Equipment:

1. Lower attachments to the ground.

2. Disengage all power and stop the engine.

3. Move hydraulic lif levers back and forth to relieve pressure.

4. Lock park brake and remove the key.

c CAUTION: Avoid injury! Avoid personal injury. Reduce compressed air to less than 210 kPA (30 psi) when using for cleaning purposes. Clear area of bystanders, guard against flying chips, wear personal protection equipment including eye protection.

5.

IMPORTANT: Avoid damage! Avoid machine damage!

· Compressed air should be used to clean ALL radiators and air screen. DO NOT use water when cleaning these areas.

· DO NOT use water to wash under hood or under seat area or where electrical components are located. Use compressed air and blow debris away. Water in electrical connections may create electrical problems.

· Do not direct high pressure water at the reel motor seals. Water may be drawn into bearings as they cool.


6. Blow debris from radiators, air screens, under the hood and seat area using compressed air.

7. Wash exterior of machine, foot platform area and reels using high volume, low pressure water.

8. Perform grease maintenance on the reels after washing to purge any moisture from system.

Care for Plastic and Painted Surfaces

PLASTIC SURFACES

The plastic parts on your greensmower 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: Avoid damage! "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.


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

Correct Cleaning Care:

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.

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.

· Be careful not to spill fuel on any plastic or painted surfaces. Wipe up fuel immediately.

Repair:

· 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.

· DO NOT use polishing compounds to attempt to remove scratches.

PAINTED METAL SURFACES

Correct Cleaning Care:

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

Repair:

Minor Scratches (surface scratch):

1. Clean area thoroughly to be repaired.

2. Use automotive polishing compound to remove surface scratches.

· DO NOT use rubbing compound to avoid removing paint.

3. Apply wax to entire surface.

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 for use and for drying.

· Apply sparingly to scratch without getting on surrounding painted surface. Fill in scratch to level of surrounding painted area.

· Allow to dry 48 hours in warm weather and up to 30 days in colder temperatures.

3. Use automotive polishing compound to smooth out surface. Do not use power buffer.

4. Apply wax to surface.
