When hitting a retainer pin, the retainer pin can fly out causing personal injury. Make sure that there are no

people in the area when hitting a retainer pin. To prevent eye injury, wear protective glasses when hitting a

retainer pin.
Chips or other debris can fly off objects when hitting the objects. Make sure that others are clear of the

area before hitting any object.

1.1.12  Hydraulic safety

The machine uses high-pressure fluids for operation. If injured by escaping fluid, seek medical attention

immediately.
• Make sure that all components in the hydraulic system are clean and in good condition, and

connections are tightened properly.

• Immediately replace any worn, cut, abraded, flattened or crimped hoses and/or steel lines.
• Wear proper hand and eye protection when searching for a high-pressure leak.
• Use a piece of wood or cardboard as a backstop to isolate any leaks.
• Never use your fingers or hands to search for leaks.
• Relieve system pressure before loosening any hydraulic lines or connections. Use extra care when

working on hydraulic circuits containing accumulators. High pressure can exist long after the machine is

shut down.

• Loosen connections slowly, keeping hands and fingers clear of loosened fittings.
• Tighten connections securely before applying pressure.
• Escaping fluid under high pressure can be almost invisible but can penetrate the skin.
• Consult a doctor immediately if you sustain an injury by escaping fluids. Serious reactions can quickly

result.

• Do not attempt any makeshift repairs to the hydraulic lines, fitting, or hoses by using tape, clamps, or

cements. Such repairs will fail suddenly, creating a hazardous condition.

1.1.13  Chemical safety

DANGER:
Chemical safety hazard. Personal injury or death can occur. Wear manufacturer
recommended personal protective equipment when handling hazardous chemicals.
Potentially dangerous chemicals used with the equipment include items such as fuel,
lubricants, coolant, hydraulic fluid, paints and adhesives in addition to the agricultural
chemicals being applied.

Always wear approved protective equipment and

clothing recommended by the chemical

manufacturer.
Before reloading the machine, wear personal

protective equipment as required by pesticide use

instructions and the chemical manufacturer

recommendations. Before entering the cab,

remove protective equipment. Store protective

equipment outside the cab in a closed box or

another type of sealable container. Clean any

shoes or boots to remove soil or other

contaminants before entering the cab.
If dangerous chemicals come in contact with the

body, wash immediately according to the chemical

manufacturer's recommendations.
Never put nozzles, tips or other parts to lips to

blow out trash or debris. Have spare tips available

for replacement.
