THANK YOU!

Handle Fluids Safely-Avoid Fires

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

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

First Aid Kit

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

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

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

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

Remove the Key

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 you must work on a lifted machine or attachment, securely support the machine or attachment 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 tractor, always follow safety precautions listed in the implement operator′s manual

Clothing

Protective Clothing

Wear close fitting clothing and safety equipment appropriate to the job.

Operating equipment safely requires the full attention of the operator Do not wear radio or music headphones while operating machine.

Work in Clean Area Wear

Clean Work 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.

Service Machines

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 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

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

Do all work outside or in a well ventilated area. Dispose of paint and solvent properly.

Remove paint before welding or heating:

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

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 be accidentally cut 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

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
