

Air in hydraulic systems can cause erratic oper-

ation and allows loads or equipment components

to drop unexpectedly. When connecting equipment

or hoses or performing any hydraulic maintenance,

purge any air in hydraulic system by operating all

hydraulic functions several times. Do this before

putting into service or allowing anyone to

approach the equipment.



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.



After connecting hoses, check that all control

lever positions function as instructed in the Opera-

tor's Manual. Do not put into service until control

lever and equipment movements are correct.



Your dealer can supply original equipment

hydraulic accessories and repair parts. Substitute

parts may not meet original equipment specifica-

tions and may be dangerous.



Set tractor hydraulic relief valve at 2500 psi (170

bars) (17,000 kPa) to prevent injury and equipment

damage due to hydraulic system failure.



Remove accumulated debris from this equip-

ment, power unit, and engine to avoid fire hazard.



Make sure all safety decals are installed.

equipment for eyes, hair, hands, hearing, and head;

and respirator or filter mask where appropriate.



Make sure attachment is properly secured,

adjusted, and in good operating condition.



Power unit must be equipped with ROPS or

ROPS cab and seat belt. Keep seat belt securely

fastened. Falling off power unit can result in death

from being run over or crushed. Keep foldable

ROPS system in “locked up” position at all times.

(Safety Rules continued on next page)

Safety is a primary concern in the design and

manufacture of our products. Unfortunately, our

efforts to provide safe equipment can be wiped

out by an operator’s single careless act.

In addition to the design and configuration of

equipment, hazard control and accident preven-

tion are dependent upon the awareness, con-

cern, judgement, and proper training of

personnel involved in the operation, transport,

maintenance, and storage of equipment.

It has been said, “The best safety device is an

informed, careful operator.” We ask you to be

that kind of operator.

place any part of the body underneath equipment

or between moveable parts even when the engine

has been turned off. Hydraulic system leak-down,

hydraulic system failures, mechanical failures, or

movement of control levers can cause equipment

to drop or rotate unexpectedly and cause severe

injury or death.

• Service work does not require going under-

neath.

• Read Operator's Manual for service instruc-

tions or have service performed by a qualified

dealer.



Keep all persons away from operator control

area while performing adjustments, service, or

maintenance.

and need assistance, see your dealer.

LUBRICATION

Do not let excess grease collect on or around parts,

particularly when operating in sandy areas.

See Figure 8 for lubrication points and frequency for

lubrication based on normal operating conditions.

Severe or unusual conditions may require more fre-

quent lubrication.

Use a lithium grease of #2 consistency with a MOLY

(molybdenum disulfide) additive for all locations. Be

sure to clean fittings thoroughly before attaching

grease gun. One good pump of most guns is sufficient

when lubrication schedule is followed.

Figure 8. Lubrication Points

NOTICE

■

Do not use excessive amounts of grease on

bearings (5). Excessive amounts of grease can

cause seal damage and/or premature bearing fail-

ure.

SERVICING TIRES SAFELY

Used Aircraft Tires (Figure 10)

Do not attempt to mount a tire unless you have the

proper equipment and experience to perform the job.

Always maintain the correct tire pressure. Do not inflate

tires above the recommended pressure. Never weld or

heat a wheel and tire assembly. The heat can cause an

increase in air pressure and result in a tire explosion.

Welding can structurally weaken or deform the wheel.

When inflating tires, use a clip-on chuck and an exten-

sion hose long enough to allow you to stand to the side

— not in front of or over the tire assembly. Use a safety

cage if available.

Check wheels for low pressure, cuts, bubbles, dam-

aged rims, or missing lug bolts and nuts.

Never remove split rim assembly hardware (A) with the

tire inflated.
