Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
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.
PREPARATION
Check that all hardware is properly installed.
Always tighten to torque chart specifications
unless instructed otherwise in this manual.
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.
Replace if damaged. (See Safety Decals section for
location.)

to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
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.

SERVICE
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
Before servicing, adjusting, repairing or unplug-
ging, stop tractor engine, place all controls in neu-
tral, set park brake, remove ignition key, and wait
for all moving parts to stop.
Never perform service or maintenance with
engine running.
NEVER GO UNDERNEATH EQUIPMENT. Never
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.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
If you do not understand any part of this manual
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.
