TS272-UN: Pesticide Use

CAUTION: This enclosed cab does not protect against inhaling vapor, aerosol or dust.

1. When operating in an environment where pesticides are present, wear a long-sleeved shirt, long-legged pants, shoes, and socks.

2. If pesticide use instructions require respiratory protection, wear an appropriate respirator inside the cab.

3. Wear personal protective equipment as required by the pesticide use instructions when leaving the enclosed cab:

into a treated area to work with contaminated application equipment such as nozzles which must be cleaned, changed or redirected to become involved with mixing and loading activities

TS220-UN: Harmful Pesticides

4. Before re-entering the cab, remove protective equipment and store either outside the cab in a closed box or some other type of sealable container or inside the cab in a pesticide resistant container, such as a plastic bag.

5. Clean your shoes or boots to remove soil or other contaminated particles prior to entering the cab.

Safety

Use a Safety Chain

TS217-UN: Safety Chain

A safety chain will help control drawn equipment should it accidentally separate from the drawbar.

Using the appropriate adapter parts, attach the chain to the tractor drawbar support or other specified anchor location.

Provide only enough slack in the chain to permit turning.

See your John Deere dealer for a chain with a strength rating equal to or greater than the gross weight of the towed machine.

Do not use safety chain for towing.

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.

DX,CLEAN-19-19900604

Decommissioning — Proper Recycling and Disposal of Fluids and Components

TS1133-UN: Recycle Waste

Safety and environmental stewardship measures must be taken into account when decommissioning a machine and/or component. These measures include the following:

Use appropriate tools and personal protective equipment such as clothing, gloves, face shields or glasses, during the removal or handling of objects and materials.

Follow instructions for specialized components.

Release stored energy by lowering suspended machine elements, relaxing springs, disconnecting the battery or other electrical power, and releasing pressure in hydraulic components, accumulators, and other similar systems.

TM139219 (01.12.2018)

210-05B-3

Minimize exposure to components which may have residue from agricultural chemicals, such as fertilizers and pesticides. Handle and dispose of these components appropriately.

Carefully drain engines, fuel tanks, radiators, hydraulic cylinders, reservoirs, and lines before recycling components. Use leak-proof containers when draining fluids. Do not use food or beverage containers.

Do not pour waste fluids onto the ground, down a drain, or into any water source.

Observe all national, state, and local laws, regulations, or ordinances governing the handling or disposal of waste fluids (example: oil, fuel, coolant, brake fluid); filters; batteries; and, other substances or parts. Burning of flammable fluids or components in other than specially designed incinerators may be prohibited by law and could result in exposure to harmful fumes or ashes.

Service and dispose of air conditioning systems appropriately. Government regulations may require a certified service center to recover and recycle air conditioning refrigerants which could damage the atmosphere if allowed to escape.

Evaluate recycling options for tires, metal, plastic, glass, rubber, and electronic components which may be recyclable, in part or completely.

Contact your local environmental or recycling center, or your John Deere dealer for information on the proper way to recycle or dispose of waste.

Read the fire extinguisher instructions and become familiar with their location, parts, and operation before a fire starts. Local fire departments or fire equipment distributors may offer fire extinguisher training and recommendations.

If your extinguisher does not have instructions, follow these general guidelines: 1. Pull the pin. Hold the extinguisher with the nozzle pointing away from you, and release the locking mechanism.

2.Aim low. Point the extinguisher at the base of the fire.

TS227-UN: Flames

Freeing a Mired Machine

TS263-UN: Cable Recoiling

Attempting to free a mired machine can involve safety hazards such as the mired tractor tipping rearward, the towing tractor overturning, and the tow chain or tow bar (a cable is not recommended) failing and recoiling from its stretched condition.

Back your tractor out if it gets mired down in mud. Unhitch any towed implements. Dig mud from behind the rear wheels. Place boards behind the wheels to provide a solid base and try to back out slowly. If necessary, dig mud from the front of all wheels and drive slowly ahead.

If necessary to tow with another unit, use a tow bar or a long chain (a cable is not recommended). Inspect the chain for flaws.

Make sure all parts of towing devices are of adequate size and strong enough to handle the load.

TS1645-UN: Tractor Tipping

Always hitch to the drawbar of the towing unit. Do not hitch to thefrontpushbarattachmentpoint.Beforemoving,clearthearea of people. Apply power smoothly to take up the slack: a sudden pull could snap any towing device causing it to whip or recoil dangerously.
