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
Prevent Battery Explosions
Keep sparks, lighted matches, and open flame away from the top of battery Battery gas can explode
Never check battery charge by placing a metal object across the posts. Use a volt-meter or hydrometer.
Do not charge a frozen battery; it may explode Warm battery to 16°C (60°F)
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.
Prevent Acid Burns
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
Handle Chemical Products Safely
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
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.
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
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.
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
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
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.
Illuminate 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.
Replace 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 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
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
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.
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
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.
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 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
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.
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.
Prevent Machine 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
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
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
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 PTO driveline is stopped before making adjustments, connections, or cleaning out PTO driven equipment.
Protect Against 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.
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.
