12 Operation
MAN0306 (Rev. 5/23/2008)
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 sub-frame has been installed and
adjusted.
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.
When operating controls, always sit in backhoe
seat.
