OPERATION
The operator is responsible for the safe operation of the backhoe. The operator must be properly trained. Operators should be familiar with the backhoe, the tractor, and all safety practices before starting opera- tion. Read the safety rules and safety decals on pages 7 to 11.
Make sure all hydraulic hoses, fittings, and valves are in good condition and not leaking before starting power unit or using equipment. Check and route hoses carefully to prevent damage. Hoses must not be twisted, bent sharply, kinked, frayed, pinched, or come into contact with any moving parts. Operate moveable components through full operational range to check clearances. Replace any damaged hoses immediately.
Make sure that all operating and service person- nel know that if hydraulic fluid penetrates skin, it must be surgically removed as soon as possible by a doctor familiar with this form of injury or gan- grene, serious injury, or death will result. CON-
TACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.
Before working on backhoe, extend boom and dipperstick and place bucket on ground. Make sure that all system pressure has been relieved by oper- ating controls before maintenance, service, or dis- connecting any hydraulic lines.
Keep hands and body away from pressurized lines. Use paper or cardboard, not hands or other body parts to check for leaks. Wear safety goggles. Hydraulic fluid under pressure can easily penetrate skin and will cause serious injury or death.
Consult local utilities before working. Know location of all underground cables, pipelines, over- head wires, and other hazards in working area and avoid contact.
A minimum 20% of tractor and equipment weight must be on tractor front wheels with back- hoe in transport position. Without this weight, trac- tor could tip over, causing personal injury or death. The weight may be attained with a loader, front wheel weights, ballast in tires, or front tractor weights. When attaining the minimum 20% weight on the front wheels, you must not exceed the Roll Over Protection Structure (ROPS) weight certifica-
tion. Weigh the tractor and equipment. Do not esti- mate.
Never put backhoe into service unless backhoe manufacturer's
OPERATION
Keep bystanders away from operator, stabilizer, and maximum bucket swing areas.
Do not use backhoe for craning; it is primarily designed for digging. Mechanical failures such as hose rupture will cause a load to drop suddenly.
Never allow children or untrained persons to operate equipment.
CAUTION
When operating controls, always sit in backhoe seat.
