ASAFETY PRECAUTIONSA
In addit ion to endangering life·and physical well-being, accidents can cause
loss of money and man-
hour s. Most farm accidents can be avoided if all persons
working with and around the equipment use common sense and observe basic
safety rules.
1. Make sure
that all drivers know how to operate the tractor properly and
safely.
2.
Allow only the operator on the tractor. Do not allow anyone el se on the
tractor . Keep children away at all times.
3.
Prior to use, inspect all equipment to insure that it is in good condition. Do
not operate equipment with damaged or missing parts.
4. Be sure all
tractor controls are in neutral before starting the engine.
5. Keep hands and
cloth ing away from mov ing parts.
6. Do
not leave a running tractor unattended .
7.
Prior to starting the tractor , blow the horn to warn all persons working near
the tractor.
8. Always keep a firm grip on the steering wheel.
9. Do not exceed safe
dr iving speeds.
10. Engage the c
lutch slowl y, especially when driv ing up steep hills or out of
ditches . There is always the possib i lity of the front end rising off the ground .
Should this happen, disengage the clut ch.
11 . Alwa ys keep the tractor in gear when going down steep hills or grades .
12.
Slow-mov ing vehicl es on highways can be dangerous . Use a slow-moving
vehicle sign in conjunction with flashing warning lights, headlights , and
taillights.
13. Do not
operate tractor engine in closed garage or shed.
14. Do not tie
chains or ropes to axles or to other parts of the tractor chassis.
Alwa ys hitch the load to the drawbar in the lowest possible position.
15. Alwa ys take up slack in chain or cable gradually .
3

16. Alw ays wait until the tractor comes to a c ompl ete halt before dismounting .
17. Before
dismounting the tractor, stop the PTO and low er all implements to
the
ground .
18. Always
park the tractor with the brakes locked. Do not depend on the gears
to hold the trac tor in a parked position.
19. Do not make r epa irs or adjustments w hile the equip ment is running.
20. Never stand between the tra cto r and the drawn implement , unless the trans-
mission is in n eutra l and the brakes are lo cked.
21. Before serv icin g an implement, di sengage the PTO.
22 . Never refuel the t ractor when the engine is hot or running.
23. Do not light m atches or smoke while fi llin g the fuel tank.
24 . Before removing the radiator cap, relieve the pre ssure in the coo lin g system
by
carefully turning the cap to its first posi tion .
25. Keep the
brakes adjusted pro perly .
26. Disconn
ect the battery ground wire and the battery connector cable before
making any adjust ments on the en gine or electrical systems.
27. Storage batt eries give off highly explosive hydrogen gas when being
charged . Keep away from sparks and flames.
28. If battery el ectrolyte contacts skin or cloth ing , wash immedi ately with water .
29 . Escaping hydraulic oil can have extre mely high pressure . A stream of it
can easily
penetrate the skin and cause b loo d po ison ing. All conn ect ions
must be
tight and all lines and pipes must be in go od condition . Be sure to
relieve all
hydraulic pressure before disconnecting any lines or pipes on
the
tractor hydraulic syste m. Keep all gua rds and shields in place.
30. Store lubrica nts, fuel and solvents away from other flamm able materials.
31 . Use a dr y chemical or CO2 ex tinguisher on fuel, oil or el ectrical fires.
32. When
parts need replaci ng, use only parts approved by Long Mfg . N. C. Inc.
Do not use
substitute parts.

Introduction
The LONG 460 tractor, is a wheeled all-purpose tractor, with pneumatic tires,
intended for farming operations carried out in conjunction with trailed and
suspended implements as well as for transport jobs.
It is a mean power tractor , equipped with a Diesel engine of 45 HP at 2400
r.p.m ., with direct fuel injection and electric start.
Its hydraulic system
as well as the front and rear axle track adjustment enable
the LONG 460 tractor to operate with a diversity of agricultural implements and
to cope with many farming jobs.
The V-460 vineyard model derives from the U-445 tractor and differs from it
by:
-rear axle housing with hand-actuated differential l
ock
-narrower final drive housing
-front axle -lower and narrower
-front wheel with 5.00-15 tires (rim. 3.00 D X 15)
-read wheel with 11.20-28 tires (rim W 1OX 28)
-electrical equipment.
The L-460 tractor , meant for high clearance gardening derives from the
LONG-460 tractor and differs from it as follows:
-
front axle with longer steering knuckle pin
-final drive housing rotated by 36°
-rear wheels with 9.50-36 tires (rim W8 X 36)
-electrical equipment.

Mec
hanic al r egula tor and automatic spill po int variator.
The
pump element ensures fuel delivery un der high pressure . It c onsists of
two opposite plungers in a rotor turning in hy draulic head. Plungers displace-
ment takes place under the influence of cam ring which the plungers come into
c ontact with by means of rollers . Centr if uga l mechanical r egulator belon gs also
to the pump asse mbl y. It accura tely adjusts the fuel delivered by injection pump
acco rding to engine loading .
Automatic spill point variator ensures accurate spi ll com men ceme nt. This
device belongs to the injection pump assembl y.
Transfer pump included into fuel circuit between fuel filter and m eter ing
valve
consists of a two blade rotor . It is in stalled on main rotor shaft, runnin g
in an
ecc e ntric bushing which is fitted in side the injection pump cover .
