Handle Chemical Products Safely
Material Safety Data Sheet
Direct exposure to hazardous chemicals can cause serious injury. Potentially hazardous chemicals used with John Deere equipment include such items as lubricants, coolants, paints, and adhesives.
A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques.
Check the MSDS before you start any job using a hazardous chemical. That way you will know exactly what the risks are and how to do the job safely. Then follow procedures and recommended equipment.
(See your John Deere dealer for MSDS’s on chemical products used with John Deere equipment.)
Avoid High-Pressure Fluids
Inspect hydraulic hoses periodically – at least once per year – for leakage, kinking, cuts, cracks, abrasion, blisters, corrosion, exposed wire braid or any other signs of wear or damage.
Replace worn or damaged hose assemblies immediately with John Deere approved replacement parts.
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.
High Pressure
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 in English from Deere & Company Medical Department in Moline, Illinois, U.S.A., by calling 1-800-822-8262 or +1 309-748-5636.
Park Machine Safely

Before working on the machine:
Lower all equipment to the ground. Stop the engine and remove the key. Disconnect the battery ground strap. Hang a "DO NOT OPERATE" tag in operator station.
Support Machine Properly
Support Properly
Always lower the attachment or implement to the ground before you work on the machine. If the work requires that the machine or attachment be lifted, provide secure support for them. If left in a raised position, hydraulically supported devices can settle or leak down.
Do not support the machine on cinder blocks, hollow tiles, or props that may crumble under continuous load. Do not work under a machine that is supported solely by a jack. Follow recommended procedures in this manual. When implements or attachments are used with a machine, always follow safety precautions listed in the implement or attachment operator′s manual.
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.
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.
Service Machines Safely
Moving Parts
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
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.
Illuminate Work Area Safely
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.

Safety Signs
Replace missing or damaged safety signs. See the machine operator’s manual for correct safety sign placement.
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.
Wait Before Opening High-Pressure Fuel System
High-Pressure Fuel Lines
High-pressure fluid remaining in fuel lines can cause serious injury. Only technicians familiar with this type of system should perform repairs. Before disconnecting fuel lines, sensors, or any other components between the high-pressure fuel pump and nozzles on engines with High Pressure Common Rail (HPCR) fuel system, wait a minimum of 15 minutes after engine is stopped.
Service Accumulator Systems Safely
Hydraulic Accumulator
Escaping fluid or gas from systems with pressurized accumulators that are used in air conditioning, hydraulic, and air brake systems can cause serious injury. Extreme heat can cause the accumulator to burst, and pressurized lines can be accidentally cut. Do not weld or use a torch near a pressurized accumulator or pressurized line.
Relieve pressure from the pressurized system before removing accumulator.
Relieve pressure from the hydraulic system before removing accumulator. Never attempt to relieve hydraulic system or accumulator pressure by loosening a fitting.
Accumulators cannot be repaired.
Remove Paint Before Welding or Heating
Toxic Fumes
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
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.
Keep ROPS Installed Properly
Roll-Over Protective Structure
Make certain all parts are reinstalled correctly if the roll-over protective structure (ROPS) is loosened or removed for any reason. Tighten mounting bolts to proper torque.
The protection offered by ROPS will be impaired if ROPS is subjected to structural damage, is involved in an overturn incident, or is in any way altered by welding, bending, drilling, or cutting. A damaged ROPS should be replaced, not reused.
The seat is part of the ROPS safety zone. Replace only with John Deere seat approved for your tractor.
Any alteration of the ROPS must be approved by the manufacturer.
Service Tires Safely
Explosive Tire and Rim Parts
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 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. Use a safety cage if available.
Check wheels for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.
Avoid Harmful Asbestos Dust
Asbestos Dust
Avoid breathing dust that may be generated when handling components containing asbestos fibers. Inhaled asbestos fibers may cause lung cancer.
Components in products that may contain asbestos fibers are brake pads, brake band and lining assemblies, clutch plates, and some gaskets. The asbestos used in these components is usually found in a resin or sealed in some way. Normal handling is
not hazardous as long as airborne dust containing asbestos is not generated.
Avoid creating dust. Never use compressed air for cleaning. Avoid brushing or grinding material containing asbestos. When servicing, wear an approved respirator. A special vacuum cleaner is recommended to clean asbestos. If not available, apply a mist of oil or water on the material containing asbestos.
Keep bystanders away from the area.
Keep Area Clean
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
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
Recycle Waste
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.
Prevent Machine Runaway
Machinery Runaway
Avoid possible injury or death from machinery runaway.
Do not start engine by shorting across starter terminals. Machine will start in gear if normal circuitry is bypassed.
NEVER start engine while standing on ground. Start engine only from operator’s seat, with transmission in neutral or park.
Handle Starting Fluid Safely
Store 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.
Service Cooling System Safely
Cooling System
Explosive release of fluids from pressurized cooling system can cause serious burns.
Shut off engine. Only remove filler cap when cool enough to touch with bare hands. Slowly loosen cap to first stop to relieve pressure before removing completely.
Stay Clear of Rotating Drivelines
Rotating Drivelines
Drivelines
Entanglement in rotating driveline can cause serious injury or death.
Keep tractor master shield and driveline shields in place at all times. Make sure rotating shields turn freely.
Wear close fitting clothing. Stop the engine and be sure that PTO driveline is stopped before making adjustments, connections, or cleaning out PTO driven equipment.
Do not install any adapter device between the tractor and the primary implement PTO drive shaft that will allow a 1000 rpm tractor shaft to power a 540 rpm implement at speeds higher than 540 rpm.
Do not install any adapter device that results in a portion of the rotating implement shaft, tractor shaft, or the adapter to be unguarded. The tractor master shield shall overlap the end of the splined shaft and the added adaptor device as outlined in the table.
Stay Clear of Rotating Drivelines
Protect Against High Pressure Spray
High Pressure Spray
Spray from high pressure nozzles can penetrate the skin and cause serious injury. Keep spray from contacting hands or body.
If an accident occurs, see a doctor immediately. Any high pressure spray 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.
