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 page 7
to page 11.
Hydraulic pressure for backhoe operation is supplied
by a tractor PTO driven pump. Two pumps are avail-
able to operate at either 540 or 1000 rpm. Make sure
you have the proper pump for your tractor rpm. Never
exceed the rated pump rpm. Operating the pump in
excess of the rated rpm will cause overheating and
damage to the equipment.
„
Never put backhoe into service unless backhoe
manufacturer's 3-point hitch Saf-T-Lok
®
limiter or
sub-frame has been installed and adjusted.
„
Do not operate backhoe unless there is ade-
quate operator clearance as shown on safety
decal. (Refer to Danger decal in Safety Decal sec-
tion.)
„
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-

ENTERS SKIN OR EYES. DO NOT DELAY.
„
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.
Start and Stop Operation
„
Operate tractor PTO at 540 RPM. Do not exceed.
Power for operating backhoe hydraulic system is sup-
plied by a hydraulic pump driven by the tractor PTO.
Instructions for engaging and disengaging the PTO are
in your tractor manual. Learn how to disengage PTO
quickly should an emergency occur.
Never exceed the rated pump rpm. Operating the
pump in excess of the rated rpm will cause overheating
and equipment damage.
GENERAL OPERATION
„
Place and keep 3-point lift quadrant lever in low-
ered position at all times.
„
If tractor is equipped with draft sensing control,
set control to “HEAVY” (minimum sensitivity) posi-
tion.
„
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.
Mechanical failures such as a hose rupture will cause a
load to drop. Lifting a heavy load with the dipper, then
operating the boom, could cause boom to drop. In
either case, if anyone is in the operating area (maxi-
mum reach of bucket) as shown in Figure 3, serious
injury or death could occur.
Do not dig with backhoe unless stabilizers are down
and on a firm surface. Stay clear of steep areas or
excavation banks that are soft or could give way.
