WORK SAFELY FOLLOW THESE RULES
This symbol is used to call your attention to
instructions concerning your personal safety.
Be sure to observe and follow these instructions.
A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST
AN ACCIDENT
BEFORE STARTING Know the controls and what they
do. When fueling an engine, keep any type open
flame away. Do Not Smoke! Wait for the engine to
cool before refueling it. Check brakes and clutch
for correct adjustments. Reduce tipping hazards
by spreading wheels as far as your work program
permits. Check coolant and engine oil levels, and
perform any other necessary services, before
starting the engine. Clean dirt, trash, and
grease from operator's platform, pedals, steps
and steering wheel. Always carry a Charged
fire extinguisher and a first aid kit.
Mounting assist handles and steps are provided
for your safety. Use them when getting on or off
the tractor. Put all controls in neutral before
starting the engine. Be suFe power take-off lever
is in the OFF or disengaged position before
starting engine. Before starting engine make sure
helpers or observers stand clear of
equipment. Operate the engine only in well
ventilated areas. Release park brake completely
prior to moving tractor. Be sure muffler and
exhaust pipe extensions are in place so exhaust
gases are discharged above operator. Check
overhead clearance carefully before driving under
power lines, guy wires, bridges, low hanging tree
branches, entering or leaving buildings, etc.
Avoid loose-fitting clothing, which could catch
on moving parts.

WORK SAFELY FO LLOW THESE RULES
DURING OPERATION Hydraulic fluid escaping under
pressure can have enough force to penetrate the
skin. Hydraulic fluid may also infect a minor cut
or opening in the skin. If injured by escaping
fluid, see a doctor at once. Serious infection or
reaction can result if medical treatment is not
given immediately. Make sure all connections are
tight and that hoses and lines are in good
condition before applying pressure to the system.
Relieve all pressure before disconnecting the
lines or performing other work on the hydraulic
system. To find a leak under pressure use a small
piece of cardboard or wood. Never use
hands. Power take-off master shield must always
be in place on the tractor. Use the drawbar in
lowest position when hitching to a heavy load,
such as manure spreaders, loaded two-wheel
trailers, and heavy wagons. Pull only from
drawbar never hitch to axle housing. Shift
transmission to neutral and set park brake before
dismounting from tractor for any reason. Always
keep safety shields in place. Disengage PTO and
shut off the engine before adjusting or
unclogging power driven machinery. Only the
operator should ride on the tractor. He should
sit on seat or stand on the platform. Keep
others, escpecially children, from riding on
steps, fenders, or drawbar, and away from tractor
and equipment. Reduce speed before making a
turn. Only the operator should ride on the
tractor. He should sit on the seat or stand on
the platform. If the tractor has roll over
protective frame or cab, sit on seat with safety
belt fastened. Always keep the tractor in gear
when going down steep hills. A towed vehicle
having a gross weight greater than the weight of
the towing tractor must be equipped with its own
brakes. Always avoid sudden starts, excessive
speed, and sudden stops. Carefully supervise
inexperienced operators. Stop the engine before
leaving the tractor and engage the park
brake. After an upset, no attempt should be made
to straighten, weld, or otherwise repair the
protective frame or protective cab for further
service. It must be replaced in its entirety. To
assure the protection provided by design, the
protective structure must not be altered by
welding, cutting, drilling, or in any other
manner. NOTE Do not operate the tractor or run
the engine until a thorough inspection has been
made to determine that all components, controls,
system, etc., are operating correctly. The
tractor must be inspected for other damage,
preferably, by your International Harvester
dealer, and all neces- sary corrections made.
TRACTORS WITH CABS Be sure cab doors are securely
latched when operating the tractor. Always use
the seat belts, if they are furnished with the
unit. F\owever, do not install seat belts if the
tractor has no protective frame. Adjust rear view
mirrors for maximum vision. Lock the cab doors,
if locks are furnished, when leaving the tractor.
TRANSPORTING Reduce speed when traveling on rough
roads. Avoid heavily-traveled roads when moving
equip- ment, if at all possible. Use warning
devises (i.e. flags, S.M.V. emblem, lights, etc.)
which are approved for use by your local
government agencies, when moving equip- ment on
public roads. Keep these devices clean and in
good working condition. When transporting
equipment on the highway, it is recommended that
a safety chain with a 10,500 pound (4,767.00 Kg)
gross load capacity be used. Be sure hitches
and/or drawbars are properly stabilized before
towing equipment. When moving on public roads, or
from field to field, lock brake pedals together
for simultaneous operation when making a stop. Be
courteous, have consideration for other traffic
using the road.
AFTE!3 OPERATING Wait for tractor to "STOP"
before dismounting. Lower equipment to ground
before leaving tractor. Shut off engine and
remove ignition key. Lock the park brake so
tractor will not roll. To remove the radiator cap
when the engine is "HOT", turn the cap to the
pressure release point let pressure and steam
escape then remove it.

BEFORE OPERATING Y0UR NEW TRACTOR
TRACTOR BREAK-IN PROCEDURE AIR CLEANING SYSTEM
Never operate an engine immediately under full
load. Break it in carefully as shown in the
table. Do not overload the engine at any time.
Refer to "Air Cleaning System".
Allow engine to warm up before operating at full
load. If engine coolant temperature rises above
middle mark or RUN range on temperature gau ge,
shift to lower gear.
ENGINE COOLING SYSTEM
Never start or operate the engine without first
checking to see if the radiator is filled to the
proper level, for the prevailing temperature,
with soft or rain water or antifreeze. Refer to
"Cooling System". Tractors shipped in the United
States and Canada have the cooling system filled
with anti- freeze.
Period Engine Speed Control Lever Position Load
1st Hour Fully advanced Maintain engine speed 100 RPM above full load governed speed.
2nd Through Sth Hours Fully advanced Full load gov- erned speed with occassional short periods of lighter load.
PRIMING THE TURBOCHARGER Before starting a new
engine or when the engine has been idle for a
month or more, the turbo- charger must be primed.
Refer to Engine and Fuel System.
During first 100 hours of operation with shipaway
oil, avoid prolonged periods of engine idling,
but do not overload. Hydraulic filter elements
must be changed as specified in "Lubrication
Guide".
FUEL SYSTEM Refer to Engine and Fuel System.
Any attempt to increase the engine horsepower by
increasing engine r.p.m. above its rated maximum,
or by other means, not only affects traveling
speeds but affects the life of matching parts and
voids the company responsibility as outlined in
the warranty.
PREPARING THE TRACTOR FOR EACH DAY'S WORK Check
the level of the coolant in the radiator. See
"Cooling System".
LUBRICATION
Lubricate the entire tractor, using the
"Lubrication Guide" and the "Lubrication Table"
for reference. Check the oil levels. Refer to
"Lubrication".
Check the oil level in the engine crankcase. Also
lubricate the chassis points recommended for
daily service. Refer to "Lubrication Guide" and
the "Lubrication Table".

FUEL GAUGE
foot
adjustment lever at the right side of the
seat. When the key switch is turned on, the fuel
gauge indicates the level of the fuel in the fuel
tank. NOTE An in-line fuse holder with AGC-1
amp. fuse located at fuel gauge receiving unit is
provided to prevent damage to fuel gauge sending
unit if any incorrect connection is made on fuel
gauge. It is important to use the same capacity
fuse for replacement. If fuel gauge fails to
function check thefuse. NOTE The key must be
left in the ON position while the engine is
running so the fuel gauge will function. FILLING
THE FUEL TANK
CAUTION! Never remove the fuel tank cap or fill
the fuel tank when the engine is running, is hot,
or when near an open flame. Do not smoke when
working around inflam- mable fuel as the air
around the tractor is mixed with highly explosive
vapor. When pouring fuel, keep the container or
hose nozzle in contact with the metal of the fuel
tank to avoid the possibility of an electric
spark igniting the fuel.
handle
Adjustment lever Seat adjustment controls. Seat
suspension is adjustable to suit the weight of
any operator from J00 to 250 pounds (45.40 to
113.50 Kg). Turn adjuster handle to slide the
pointer along the scale to match the operator's
weight. Place handle in horizontal position after
adjustment is made.
Fill the fuel tank, preferable at the end of each
day's work. This will force out any
moisture-laden air and prevent condensation. NOTE
Do not fill the tank to its full capacity as
space is required for vapor expansion in the
event of a temperature change. A tank filled to
capacity may overflow if exposed to a rise in
temperature or direct sunlight.
The back cushion of the seat can be adjusted to
three different positions to the front or rear
and three different heights by means of the
mounting holes in the back cushion support. The
back rest extension is also adjustable to three
different heights.
The filler cap on the fuel tank has an air vent.
This vent should be kept open at all times to
assure proper flow of the fuel.
Before starting the tractor for each day's work,
open the fuel ank water drain cock on the left,
bottom side of the fuel tank to drain off water
and sediment. Close the drain as soon as clean
fuel appears.
Foot Release Lever
The foot release lever provides means of moving
the seat rearward from a preset position when the
operator is driving the tractor from a standing

DRIVING THE TRACTOR
STEERING THE TRACTOR The tractor is steered in
the conventional manner by means of the steering
wheel actuating the power steering. To steer the
tractor with the two front wheels only, move the
Two-Wheel Four-Wheel steering control lever
forward to the number 2 position. To steer the
tractor with both front and rear wheels, move the
control lever rearward to the number 4 position.
CAUTION! When towing the tractor ground speed
should not excœd 20 milœ (32.20 Km) per hour.
NOTE If the tractor is to be towed for any
reason, the engine must be running to provide for
trans- mission lubrication, power brakes and
power steer- ing. If the engine cannot be run,
check so the fluid level in the transmission case
is at the Full mark on the transmission oil
level gauge, then add four additional gallons of
IH Hy-Tran a fluid into the transmission
case. After towing the tractor, drain the added
four gallons (15.21) of fluid so the fluid level
in the transmission case is again at the Full
mark on the transmission oil level gauge.
Refer to Lubrication.
NOTE Do not attempt to move the Two-Wheel
Four-Wheel steering control lever when hydraulic
power is not available. Selection of two-wheel
steering or four-wheel steering can be made while
the tractor is in motion.
Use two-wheel steering for most straight-away
field operations, shifting to four-wheel steering
for sharp turns.
STOPPING THE TRACTOR
Disengage the clutch and actuate the service
brake. Move the transmission range lever to the
neutral position. Manual brakes can be used for
emergency application immediately after the
engine is stopped.
NOTE Use two-wheel steering when operating the
tractor in 2nd, 3rd, and 4th high range speed.
TOWING THE TRACTOR When towing is necessary, use
a tow rope, chain, or cable and have an operator
steer the tractor and operate the brakes. Do not
tow the tractor by the front axle. When a tractor
is stuck, the power of both tractors should be
used, and a steady, even pull maintained by the
towing tractor. When towing a tractor, place the
transmission range lever in the N (neutral)
pœition.
PARK BRAKE The park brake is activated by
stepping on the park brake pedal. It is released
by pushing down on the release lever.
