Handle Fluids Safely—Avoid Fires
When you work around fuel, do not smoke or work near heaters or other fire hazards.
Store flammable fluids away from fire hazards. Do not incinerate or puncture pressurized containers.
Make sure machine is clean of trash, grease, and debris.
Do not store oily rags; they can ignite and burn spontaneously.
Handle Starting Fluid Safely
Starting fluid is highly flammable.
Keep all sparks and flame away when using it. Keep starting fluid away from batteries and cables.
To prevent accidental discharge when storing the pressurized can, keep the cap on the container, and store in a cool, protected location.
Do not incinerate or puncture a starting fluid container.
CAUTION: Battery gas can explode. Keep sparks and flames away from batteries. Use a flashlight to check battery electrolyte level.
Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer.
Always remove grounded (-) battery clamp first and replace it last.
Do not charge a frozen battery; it may explode. Warm battery to 16C (60F).
CAUTION: Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes.
Avoid the hazard by:
1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte is added.
4. Avoiding spilling or dripping electrolyte.
5. Use proper jump start procedure.
If you spill acid on yourself:
1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize the acid.
3. Flush your eyes with water for 15—30 minutes. Get medical attention immediately.
If acid is swallowed:
1. Do not induce vomiting.
2. Drink large amounts of water or milk, but do not exceed 2 L (2 quarts).
3. Get medical attention immediately.
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
Prepare for Emergencies
Be prepared if a fire starts.
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.
Avoid High-Pressure Fluids
Escaping fluid under pressure can penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A.
Wear Protective Clothing
Wear close fitting clothing and safety equipment appropriate to the job.
Prolonged exposure to loud noise can cause impairment or loss of hearing.
Wear a suitable hearing protective device such as earmuffs or earplugs to protect against objectionable or uncomfortable loud noises.
Operating equipment safely requires the full attention of the operator. Do not wear radio or music headphones while operating machine.
Service Machines Safely
Tie long hair behind your head. Do not wear a necktie, scarf, loose clothing, or necklace when you work near machine tools or moving parts. If these items were to get caught, severe injury could result.
Remove rings and other jewelry to prevent electrical shorts and entanglement in moving parts.
Work In Ventilated Area
Engine exhaust fumes can cause sickness or death. If it is necessary to run an engine in an enclosed area, remove the exhaust fumes from the area with an exhaust pipe extension.
If you do not have an exhaust pipe extension, open the doors and get outside air into the area
Work in Clean Area
Before starting a job:
• Clean work area and machine.
• Make sure you have all necessary tools to do your job.
• Have the right parts on hand.
• Read all instructions thoroughly; do not attempt shortcuts.
Install Fan Guards
Rotating cooling system fans can cause serious injury.
Keep fan guards in place at all times during engine operation. Wear close fitting clothes. Stop the engine and be sure fan is stopped before making adjustments or connections, or cleaning near the front of the engine.
Avoid Hot Parts
Avoid skin contact with exhaust manifolds, turbochargers and mufflers. Keep flammable materials clear of the turbocharger.
External dry exhaust parts become very hot during operation. Turbochargers may reach temperatures as high as 500C (932F) under full load, and naturally aspired exhaust manifolds may reach 600C (1112F) under full load. This may ignite paper, cloth or wooden materials. Parts on engines that have been at full load and reduced to no load idle will maintain approximately 150C (302F).
Rotating Fan
Hot Surface
Remove Paint Before Welding or Heating
Avoid potentially toxic fumes and dust.
Hazardous fumes can be generated when paint is heated by welding, soldering, or using a torch.
Remove paint before heating:
• Remove paint a minimum of 100 mm (4 in.) from area to be affected by heating. If paint cannot be removed, wear an approved respirator before heating or welding.
• If you sand or grind paint, avoid breathing the dust. Wear an approved respirator.
• If you use solvent or paint stripper, remove stripper with soap and water before welding. Remove solvent or paint stripper containers and other flammable material from area. Allow fumes to disperse at least 15 minutes before welding or heating.
Do not use a chlorinated solvent in areas where welding will take place.
Do all work in an area that is well ventilated to carry toxic fumes and dust away.
Dispose of paint and solvent properly.
Avoid Heating Near Pressurized Fluid Lines
Flammable spray can be generated by heating near pressurized fluid lines, resulting in severe burns to yourself and bystanders. Do not heat by welding, soldering, or using a torch near pressurized fluid lines or other flammable materials. Pressurized lines can accidentally burst when heat goes beyond the immediate flame area.
Work Area Safely
Illuminate your work area adequately but safely. Use a portable safety light for working inside or under the machine. Make sure the bulb is enclosed by a wire cage. The hot filament of an accidentally broken bulb can ignite spilled fuel or oil.
Use Proper Lifting Equipment
Lifting heavy components incorrectly can cause severe injury or machine damage.
Follow recommended procedure for removal and installation of components in the manual.
Construct Dealer-Made Tools Safely
Faulty or broken tools can result in serious injury. When constructing tools, use proper, quality materials and good workmanship.
Do not weld tools unless you have the proper equipment and experience to perform the job.
Construct Dealer-Made Tools Safely
Practice Safe Maintenance
Understand service procedure before doing work. Keep area clean and dry.
Never lubricate, service, or adjust machine while it is moving. Keep hands, feet , and clothing from power-driven parts. Disengage all power and operate controls to relieve pressure. Lower equipment to the ground. Stop the engine. Remove the key. Allow machine to cool.
Securely support any machine elements that must be raised for service work.
Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts. Remove any buildup of grease, oil, or debris.
On self-propelled equipment, disconnect battery ground cable (-) before making adjustments on electrical systems or welding on machine.
On towed implements, disconnect wiring harnesses from tractor before servicing electrical system components or welding on machine.
Use Proper Tools
Use tools appropriate to the work. Makeshift tools and procedures can create safety hazards.
Use power tools only to loosen threaded parts and fasteners.
For loosening and tightening hardware, use the correct size tools. DO NOT use U.S. measurement tools on metric fasteners. Avoid bodily injury caused by slipping wrenches.
Use only service parts meeting John Deere specifications.
Dispose of Waste Properly
Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used with John Deere equipment include such items as oil, fuel, coolant, brake fluid, filters, and batteries.
Use leakproof containers when draining fluids. Do not use food or beverage containers that may mislead someone into drinking from them.
Do not pour waste onto the ground, down a drain, or into any water source.
Air conditioning refrigerants escaping into the air can damage the Earth’s atmosphere. Government regulations may require a certified air conditioning service center to recover and recycle used air conditioning refrigerants.
Inquire on the proper way to recycle or dispose of waste from your local environmental or recycling center, or from your John Deere dealer.
Live With Safety
Before returning machine to customer, make sure machine is functioning properly, especially the safety systems. Install all guards and shields.

Fuels, Lubricants and Coolant
Consult your local fuel distributor for properties of the Fuel lubricity should pass a minimum of 3100 gram diesel fuel available in your area. load level as measured by the BOCLE scuffing test.
In general, diesel fuels are blended to satisfy the low Sulfur content: temperature requirements of the geographical area in which they are marketed.
Diesel fuels specified to EN 590 or ASTM D975 are
• Sulfur content should not exceed 0.5%. Sulfur content less than 0.05% is preferred.
• If diesel fuel with sulfur content greater than 0.5% recommended. sulfur content is used, reduce the service interval for engine oil and filter by 50%.
In all cases, the fuel shall meet the following
• DO NOT use diesel fuel with sulfur content greater properties: than 1.0%.
Cetane number of 40 minimum. Cetane number
DO NOT mix used engine oil or any other type of greater than 50 is preferred, especially for lubricant with diesel fuel.
temperatures below -20C (-4F) or elevations above 1500 m (5000 ft).
Cold Filter Plugging Point (CFPP) below the expected low temperature OR Cloud Point at least 5C (9F) below the expected low temperature.

Consult your local fuel distributor for properties of the bio-diesel fuel available in your area.
Bio-diesel fuels may be used ONLY if the bio-diesel fuel properties meet the latest edition of ASTM PS121, DIN 51606 or equivalent specification.
It has been found that bio-diesel fuels may improve lubricity in concentrations up to a 5% blend in petroleum diesel fuel.
When using a blend of bio-diesel fuel, the engine oil level must be checked daily when the air temperature is -10C (14F) or lower. If the oil becomes diluted with fuel, shorten oil change intervals accordingly.
IMPORTANT: Raw pressed vegetable oils are NOT acceptable for use for fuel in any concentration in John Deere engines.
These oils do not burn completely, and will cause engine failure by leaving deposits on injectors and in the combustion chamber.
Lubricity of Diesel Fuel
Most diesel fuels manufactured in the United States, Canada, and the European Union have adequate lubricity to ensure proper operation and durability of fuel injection system components. However, diesel fuels manufactured in some areas of the world may lack the necessary lubricity.
IMPORTANT: Make sure the diesel fuel used in your machine demonstrates good lubricity characteristics.
A major environmental benefit of bio-diesel fuel is its ability to biodegrade. This makes proper storage and handling of bio-diesel fuel especially important. Areas of concern include:
• Quality of new fuel
• Water content of the fuel
• Problems due to aging of the fuel
Potential problems resulting from deficiencies in the above areas when using bio-diesel fuel in concentrations above 5% may lead to the following symptoms:
• Power loss and deterioration of performance
• Fuel leakage
• Corrosion of fuel injection equipment
• Coked and/or blocked injector nozzles, resulting in engine misfire
• Filter plugging
• Lacquering and/or seizure of internal components
• Sludge and sediments
• Reduced service life of engine components
RG41183,0000046 –19–18DEC01–1/1
Fuel lubricity should pass a minimum load level of 3100 grams as measured by ASTM D6078 or a maximum scar diameter of 0.45 mm as measured by ASTM D6079 or ISO 12156-1.
If fuel of low or unknown lubricity is used, add John Deere PREMIUM DIESEL FUEL CONDITIONER (or equivalent) at the specified concentration.
