THROTTLE LEVER

This lever controls the speed of the engine.

When set in a given position, it will maintaina

uniform engine speed.

GOVERNOR

The governor is set at the time the engine is assembled and should not require readjustment unless the governor arm is removed or loosened from the governor shaft. Consult

your International Harvester dealer if the

gove rnor does not function properly.

LIFTING THE HOOD

The tractor hood is arranged to swing up

and forward to make the engine and fuel tank

readily accessible.

To raise the hood, take hold of each side of the hood at the rear, pull outward, and raise it upward and forward to its stop.

THE ENGINE

STARTING THE ENGINE

Be sure the fuel shut-off valve is open.

2. Pull the choke control button all the way

out (see Illust. 3 or 4). More or less choking may be

necessary due to variations in temperature, grade of fuel, etc. Little or none will beneeded

when the engine is warm.

3. Place the throttle lever halfway between

"SLOW" and "FAST". See Illust. 3 or 4.

4. Electric Starting: The engine cannot be

started unless the brake pedal is pressed all

the way down to activate the safety starting

switch.

International Cub Cadet 71, 102, and 122

Tractors: Check to see that the gearshift leveris

in the neutral position. See Illust. 3.

International Cub Cadet 123 Tractor: Check

to see that the speed control lever is in the

I'N'I position. See Illust. 4.

All Models: Turn the ignition key clock-wise

to the "START" position and release it as soon as the engine starts; however do not operate the motor-generator for more than 30 seconds at anyone time. If the engine does not start within this time, turn the key !'OFF" and wait a few minute s. then try again.

5. After the engine starts. slowly releasethe brake pedal and gradually push the choke

control button all the way in. Do not use thechoke

to enrich the fuel mixture, except when

necessary to start the engine.

Manual Starting: (Tractors without electric

starting). Raise the tractor hood. The retract-

able starter is mounted on a support plate at the front of the engine at the right side of thetractor.

Put the gearshift lever in the neutral posi-

tion and lock the brake. Turn the key ignition

switch clockwise.

Give a quick steady pull on the retractable starter handle to start the engine. Do not jerk. or pull it out to its very end in a rough manner. A steady pull will accomplish just as much.

Always pull the handle so the cord is in a

straight line through the guide. Maintain your

hold on the handle and allow the cord to return

slowly. Releasing the handle when the cable is

extended will shorten the life of the starter.

5. After the engine starts, slowly release

the clutch pedal and gradually push the choke

control button all the way in. Do not use the

choke to enrich the fuel mixture, except when

nece s sa ry to start the engine.STOPPING

THE ENGINE

Move the throttle lever to the "SLOW" po-

sition and allow the engine to idle for a shorttime

before stopping. Then turn the key to the

"OFF" position.

SYSTEM

Fill the fuel tank with clean, fresh, regular grade gasoline, preferably at the end of each day's use. This will force out any moistureladen air and prevent condensation in the fueltank.

Do not mix oil with the gasoline.

The fuel tank filler cap has an air vent. Keep the vent open at all times to assure proper flow of the fuel.

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 inflammable fuel,as

the air around the tractor is mixed with a

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 gas. Do not spill gasoline on a hot engine.

OPERATING

FUEL

CLEANING

FUEL SHUT.OFF VALVE

Be sure the shut-off valve on the fuel

strainer under the gasoline tank is open. Screw out the needle stem (Shut-off valve) until the seat on the stem is tight against the

stop, to prevent leakage or seepage when the valve is in its full-open position.

THE FUEL STRAINER AND SEDIMENT BOWL

After every 25 hours of operation, cleanhe

fuel strainer as follows:

1. Close the shut-off valve. See Illusts.7 and 7A). Loosen the knurled nut under the sediment bowl and remove the bowl and screen.

Clean the sediment bowl and screen.

3. When reassembling, be sure the gasket

between the bowl and the main body is in good

condition and does not leak. Use a new gasket

if necessary.

CARBURETOR ADJUSTMENTS

The carburetor is adjusted at the factory and under normal operating conditions it will not require readjusting. If this adjustment has been disturbed for any reason, proceed as

follows:

Adjusting the High-Speed Adjustment Screw

Turn the high speed adjustment screw (1IIusts.

7 and 7A) counter-clockwise approximately two

turns from the closed position and start the en-gine.

After the engine has reached normal oper-

ating temperature, accelerate the engine and

check its response.

Place the engine under load and turn the high speed adjustment screw (1IIusts. 7 and 7A) to the leanest mixture that will allow satisfactory acceleration and steady governor operation.

If the engine misses and backfires under

load, the high speed mixture is too lean. The high speed adjustment screw must be turned

counte r- clockwise 1 /4 turn at a time until the

condition is corrected.

If the engine shows a sooty exhaust and is

sluggish under load, the high speed mixture is

too rich. The high speed adjustment screw

must be turned clockwise 1 /4 turn at a time

until the condition is corrected.

Carburetor and fuel strainer.

Illust.7A

(Internationol Cub Cadet 102, 122 and 123 Tractors)

For a final check of the high speed adjustment, operate the engine under load and make any corrections necessary for smooth opera-

tion.

Adjusting the Idle Adjustment Screw

After the high speed adjustment screw is

adjusted, it may be necessary to readjust the

idle adjustment screw (1IIusts. 7 and 7A), as each affects the other.

Close the idle adjustment screw to its seat

by turning it clockwise; then open it one turn.

Start the engine and operate it at fast idling speed (without any load) until thoroughly warm.

While the engine is running at fast idle

speed, it is advisable to screw in the throttle

stop sc rew (1IIusts.7 and 7 A) a few turns to keep

the engine from stopping when the throttle

lever is moved to the fully retarded "SLOW"

position. The engine will then be idling at a fairly high speed and the throttle stop screw can be backed out a little at a time until the desired idle speed is obtained.

If the engine misses or rolls while backing out the throttle stop screw. the idle adjustment

screw may be adjusted in or out until the en-

gine operates smoothly. Speed up the engine

for a few seconds; then recheck the idle ad-

justment. A slight adjustment in or out will give the smoothest idle.

PREPARING THE TRACTOR FOR EACH DAY'S WORK

Fill the fuel tank at the end of each day's

run. See page 6.

Check the crankcase oil level and add new

oil if necessary. Seepage 26.

Clean the air cleaner element if necessary.

See page 14.

Inspect the tires for general condition. See

pages 20 and 21.

STOPPING THE TRACTOR

Disengage the clutch by pressing the pedal all the way down. Move the gearshift lever to

the neutral position.

CREEPER SHIFT LEVER

The creeper drive provides a slower speed

in each respective gear, by a four-to-one re-

duction in speed from direct drive. When the

creeper shift lever is all the way forward, it is in direct drive, or all the way rearward, it is in creeper drive. See Illust. 3. Note: Do not use a mid-point position on the creeper driveas

neutral. Neutral position must be selected only with the standard transmission gearshift lever.

GEARSHIFT LEVER

This lever is used to select various gear ratios provided in the transmission. There are three forward speeds and one reverse speed. See Illust. 3. Refer to "SPECIFICA TlaNS't

on page 32.

STARTING THE TRACTOR

1. Advance the th rattle leve r s lightly. SeeIllust.

2. Disengage the clutch by pressing the

clutch pedal all the way down, and move the gearshift lever to the desired speed.

3. Start the tractor in motion by slowly

releasing the clutch pedal and moving thethrottle

Internatianal Cub Cadet 71 Tractar

If your tractor is equipped with a rear

power take-off, the following instructions and precautions should be carefully studied and followed.

The rear power take-off is started and

stopped by the same engine clutch as the tractor. Be sure to disengage the engine

clutch before moving the power take-off shift -

er rod (1IIust. 12), or shifter lever (1IIust. 12A). The shifter rod should always be in the disengaged (forward) position and the shifter

lever in the disengaged (rearward) position

when the power take-off is not in use.

Caution! Always cover the power take-off exposed shaft with the guard when the power take-off is not being used.

OPERATING THE REAR POWER TAKE.OFF

WITH TRACTOR IN MOTION

Follow the first four steps outlined above; then engage the power take-off shifter rod or lever. Keep your foot pressed down on the

clutch pedal (in the dis engaged position),

advance the throttle lever and move the

transmission gear-shift lever to the speed that is desired to run the tractor. Slowly release the clutch pedal. This will start the

tractor in motion with the power take-off in

operation.

OPERATING THE FRONT POWER TAKE.OFF CLUTCH

1. Move the throttle lever back to medium

or low idle speed.

After considerable clutch use, it may be

necessary to readjust the button clearance as

described below to assure proper clutch disengagement.

2. Move the front power take-off clutch lever (forward) to the engaged position (rearward) to the disengaged position. See

Illusts. 3 or 4 ond 13A.

Note: It is recommended that the clutch lever be placed in the forward or engaged position when the tractor is being used without front power take-off equipment.

ADJUSTING THE CLUTCH

The clutch is factory adjusted and should

not require further adjustment under normal

operating conditions. However, if clutch

slippage should occur. It is recommended that you see your International Harvester dealer for satisfactory servicing of the clutch,

as special equipment and instructions are

required.

With the clutch fully engaged (clutch lever in the forward position) place a piece of thin cardboard (match book cover) approximately

1/64 inch thick between the engaging lever

wear button IIAII and the pressure spring thrust button IIBII (1IIust. 13), loosen the jam nut

on the turnbuckle lIC't (1IIust. 13A), and adjust the turnbuckle until a light drag is felt on the cardboard when it is removed from between the buttons. Be sure all slack, except the

1/64 inch adjustment, is out of the linkage.

Then, tighten the jam nut securely against the

turnbuckle.

INSTALLING AND REMOVING DRIVE BELT

ENGINE COOLING

This tractor has an air cooled engine. Air

must be able to circulate freely around the

engine, through the screen and shroud, and over the fins of the cylinder head and cylinderblock.

Keep these areas free of accumulated dirt and trash or the engine will overheat and result in damaged moving parts.

DRY-TYPE AIR CLEANER

Incoming air for combustion is filtered by a dry-type air cleaner having a filter element inside of the cover.

Remove and clean or replace the element

with a new one when loss of power isnoticeable.

Cleaning the Element

To clean the element. remove the wing nut

and air cleaner cover (1IIust. 14) then remove the

element and tap it lightl y on a flat surface to cause the loose dirt to falloff. Handle the paper element with care to avoid perforations.Do

not use compressed air to remove the dirt

as this can rupture the element. Do not wash

or use a solvent.

The twelve-volt electrical system on a

tractor with electric starting consists princi-

pally of a motor-generator, voltage regulator, and a twelve-volt battery.

Use the illustrations on poge 17 and wiringdiagrams

on poge 18, as a guide for identifyingthe

various electrical units and for tracing the

electrical cables and connections. Be sure all

connections are clean and securely fastened.

Removing the air cleaner filter element.

Replacing the Element

Replace the element with a new one if dirt

does not drop off easily or if it is bent,crushed

or damaged. When replacing the ele-

ment be sure it fits snugly around the insideedge

of the air cleaner base. Then replace the

cover and tighten the wing nut finger tight.

engine has stalled and the operator leaves the tractor, the key must be turned to the "OFF" position to prevent battery discharge.

SAFETY STARTING SWITCH

The safety starting switch, activated by the clutch or brake pedal, serves to prevent starting the engine accidentally.

IGNITION SWITCH

Turn the key clockwise to turn on the ignition. With electric starting, a further turn actuate s the motor -generator. The key cannot

be removed when in the IIONtl position.

ELECTRICAL SYSTEM

SPARK PLUG

Note: Remove all dirt from the base of the

spark plug before removing the spark plug.

Remove the spark plug after every 100 hours of operation for cleaning and checking the gap. See Illust. 15. When making this adjustment, always bend the outer electrode. Never bend the center electrode, as it may damag:! the insulator. If the gap between the electrodes is too great, the engine will misfire and be hard to start.

Always use a spark plug wrench when removing or reinstalling the plug.

Be sure the gasket is in good condition,

and screw the plug in tightly. Do not tighten

more than enough to compress the gasket to

seal the plug and assure a good heat transfer between the plug and the cylinder head. Tighten the plug 1/2 to 3/4 turns past finger tight.

IGNITION TIMING

Illust.15A

Adjusting the breaker paints.

Set gap at .O20-inch.

Remove the breaker point cover after every

100 hours of operation for cleaning the points and resetting the gap (1IIust.15A). Replace badly pitted or burned points.

For more precise timing, a timing light

should be used. The engine has a timing sight hole which is located in the right s ide of the engine bearing plate on the International Cub

Cadet 71 Tractor or in the right side of the

blower housing in the International Cub Cadet

102, 122 and 123 Tractors. See Illust.15B.

Checking the spark plug gap.

(Ilust. 15

Set gap at .O25-inch.

Replace a defective plug with a new plug.

See your International Harvester dealer for a

correct replacement plug.

Cleaning the Spark Plug

Sandblasting is the recommended method of cleaning the spark plug. Never scrape or clean the insulator with anything which will scratch the porcelain. Scratched porcelain allows

carbon and dirt to accumulate much faster.

With the engine running at 1/3 throttle. or

more, adjust the breaker points until the "SP" mark on the flywheel is centered in the sight

hole. Note: The "Spl' mark will appear 20degrees

before top dead center. The other mark is the top center mark and is stamped with "DC'I below the mark.

ELECTRICAL SYSTEM

and Replacing the Motor-Generator Belt

The motor-generator (IZ-volt, negative

ground) will function as a cranking motor when

the ignition key is turned to the "START"

position, driving the engine by means of abelt.

When the engine is operating, the unit will

function as a generator.

MOTOR-GENERATOR BELT

Check the tension of the motor -generator belt after the first 10 hours of operation and every 50 hours of operation thereafter. The

tension is correct when the belt can be deflected a maximum of 1/4-inch by a ten pound force applied midway between the two

pulleys.

Replace the motor-generator belt when it

becomes badly worn. To remove the old belt,

loosen the motor-generator brace bolt I'A" and

mounting bolt.s lIB", Illust.17. Move the gener-

ator in toward the engine and slip the old belt off the pulleys and over the crankshaft. Install the new belt in the reverse order of removal and adjust the belt to the proper tension.

VOL TAGE REGULATOR

A satisfactory generator charging rate is

maintained by the voltage regulator. If the

regulator fails to operate correctly, see your

International Harvester dealer.

Hote: Never place a jumper lead between,

or accidentally bridge, the I'BAT'I terminal and the I'FI' terminal on the regulator, as this

will damage the regulator.

LIGHTS

The headlights are sealed-beam lights. The

parts are so constructed that the filament, re-

flector, and lens are all assembled in a unit

permanently sealed against dirt, moisture, and corrosion. If a filament burns out or a lens bxeaks, the complete unit must be replaced. Refer to I'SPECIFICA TIONS".

Also follow this procedure when a new beltis

installed.

Adjusting the Motor-Generator Belt

Loosen the motor-generator brace bolt I'A'I

and mounting bolts IIBI', Illust.17.

Move the generator away from the engine

until the tension on the belt is correct. See

Illust. 16.

Note: Under no circumstances should a pry

bar.be used on the motor-generator to obtain

belt tension as damage to the bearings will

re suIt.

FUSE (Electric Lighting)

It is important to use the same capacity fuse for replacement. Refer to "Specifications". If the lights fail. check the fuse. If a fuse continually burns out. check the electri-

cal wiring for short circuits.

The fuse is located in a fuse housing in theline

at the back of the instrument panel. See

Illust. 18.

To install a new fuse. pre ss in on the fusehousing

Description

Keeping the battery fully charged not only adds to its life but makes it available for instant use when needed.

Before working on any part of the electri-

cal system, disconnect the battery ground cable at the battery negative (-) terminal. See Illust. 17. Do not reconnect this cable until all work has been completed. This will prevent

shorting and damage to any of the electrical units. Examine the electrical cables occasion-

ally to be sure they are not being frayed by

contact with adjacent parts.

When replacing a battery, make certain the

ground cable is connected to the negative (-)

terminal on the battery. Be sure the rubber

boot is properly positioned over the positive

(+) terminal on the battery. Note: Both cables

must be assembled with the nuts to the inside

of the terminals to prevent shorting against the pedestal.

Cleaning and Servicing the Battery

Occasionally remove the battery cables and

brighten the terminal contact surfaces with

wire wool, and reassemble them. Apply a

light coat of vaseline or chassis lubricant. Be sure the terminals are clamped tightly and

that the battery is fastened securely in the battery box. Replace unserviceable cable. Keep the vent holes in the battery filler caps open.

Check the battery at least once a month for

water level.

The electrolyte (acid and water) in each

cell should be at ring level at all times to pre-

vent battery failure. When the electrolyte is

below this level, add pure, distilled water.

Acid or electrolyte should never be added

except by a skilled battery man. Under no

circumstances add any special battery !'dopes; 11

solutions or powders.

Caution! Electric storage batteries give off

highly inflammable hydrogen gas when charging and continue to do so for some time after receiving a steady charge.

Caution! Do not under any circumstances allow an electric spark or an open flame near the battery. Do not lay tools across battery terminals as this may result in a spark or

short circuit which may cause an explosion. Be careful to avoid spilling any electrolyte on hands or clothing.

For dependable battery service, see your

International Harvester dealer.

Tie rod and drog link boll joints.

The front wheel toe-in dimension is 1-32-

inch to 1/8-inch toe-in (1/32-inch to 1/8-inch

closer in front than in the rear). Measure the

distance between two points "A" and two points

"B" Illust. 20. Points "A" and "B" must be on the inside of the wheels at the outer edges and at the same height from the ground as the front

wheel hubs.

end in or out as required.

TURNING RADIUS

The front wheels should have an equal angle

for left and right turns. If adjustment is nec-

essary, disconnect the drag link ball joint I'D" (II lusts. 20 and 20A) loosen the lock nuts and turn the drag link ball joint in or out as required.

Keep tires free from oil and grease as both

destroy rubber.

After using the tractor for spraying-insect control work-use water to remove any chemicals that may be on the tires.

The Terra-Tires provide maximum mobility in sand, snow, and soft soil conditions. The reduced ground pressure and low inflation

provides maximum protection for turf, soil,

and crops.

CARE OF TIRES

Avoid stumps, stones, deep ruts and other hazards. Cuts in tires should be repaird

immediately as neglect decreases the tire life.

INFLATION

Keep the pnewnatic tires properly inflated.

Underinflation will damage the tire cord body and may also cause the tire to slip on the rim, thus tea'ring out the tube valve stem.

Always see that the tire valve caps are in place and tightened securely to prevent the loss of air and protect the valve core and stem.

PNEUMA TIC TIRES

OPERATING PRESSURE FOR TIRES

Inflate the front and rear tires for normal

or heavy load operations as shown in the fol-

lowing table.

MOUNTING TIRES ON THE RIM

After mounting a new or old tire on the

rim, inflate it to 20 pounds pressure to seat the tire bead on the rim flange and to prevent the tire from creeping and shearing off thevalve.

Then deflate the tire to the correct

operating pressure.

REAR WHEEL WEIGHTS

Rear wheel weights increase traction and reduce wheel slippage. The weights weigh approximately 26 pounds each. They are

attached to each rear wheel with two bolts,

lock washers, and hex. nuts.

If additional weight is desired. a second set

of weights can be attached to each first weight

by using two longer bolts.

TIRE CHAINS

Tire chains will provide additional traction for wet ground conditions, when plowing snow, or pulling heavy loads. Rear wheel weights

are recommended when using chains.

CLUTCH AND BRA K E

(International Cub Cadet 71, 102 and 122 Tractors)

As the clutch and brake are both operated by the same pedal, care must be taken to maintain a neutral zone so the clutch is disengaged when the brake is applied.

ADJUSTING THE CLUTCH

It is important that a clearance of .050inch be maintained between the clutch release lever and the clutch release bearing. In order

to maintain this clearance. the pedal should have a free movement of approximately 3/16-

inch. See Illust. 21. This measurement is taken

at the point of contact of the pedal arm withthe

front edge of the pedal return stop.

The clutch pedal adjustments are set at the

factory and should not require frequent attention unless the linkage has been disturbed or when the pedal movement becomes less than

3/16-inch. When it is necessary to adjust the clutch, turn the adjusting nut "A" on the clutch release rod (1IIust. 22) in or out as required to

get the proper measurements.

ADJUSTING THE BRAKE

The brake should engage when. the pedal

arm is pressed down to within a maximum of l-5/l6-inches and a minimum of 3/4-inch distance above the top of the left foot support,

which serves as the pedal stop. See Illust. 21.

It may be possible to push the pedal all the

way down to the pedal stop, but this is of no

concern as long as the brake is engaged when

the pedal arm is at least 3/4-inch above the

pedal stop.

To adjust the brake, loosen the jam nut "B" and turn the brake lever adjusting screw "C" (1IIust. 22) in or out as required to get thismeasurement.

The brake must not engagebefore

the pedal arm is within the maximum

distance of 1-5/16-inches above the pedal stop.

To adjust the brake, loosen the jam nut "B"

and turn the brake lever adjusting screw "G"

(1IIust. 23A) in or out as required to get this

measurement. The brake must not engage before the pedal arm is within the maximum distance of 1-5/16-inches above the pedal stop.

ADJUSTING THE SPEED CONTROL LEVER

Note: The brake pedal must be properly ad-

justed before beginning the speed control lever

adjustment. If the tractor "creeps" in the "N"

position or, if the speed control linkage has been disassembled or removed for any reason, the following adjustment must be made.

Block the tractor so the left rear wheel is

off the ground.

Start the engine at half throttle or faster.

Move the speed control lever to the forward position. The rear wheel should rotate in the forward direction. Depress the brake pedal all the way down and release. The speed control lever should return to the "N't position and the rear wheel stop turning.

If the rear wheel turns in the forward direction, loosen jam nut "D" and turn the connecting rod "E" counterclockwise to lengthen it

until the wheel stops turning. (See Illust. 23A).

STORAGE

Store your tractor in a dry and protectedplace.

Leaving your tractor outdoors, ex-

posed to the elements. will result in materially shortening its life.

storing the tractor:

1. Wash or clean and completely lubricate

the tractor. See the "Lubrication Guide" on

poges 28 to 32.

2. Drain the fuel tank and run the engine

until the fuel is exhausted from the fuel system. Clean the fuel strainer screen and glass bowl. See page 6.

Hote: Gum will eventually form in the fuel tank, line, and carburetor if the unit is not drained. Gum can be dissolved with acetone

or a 50-50 mixutre of alcohol and benzol.

3. After the engine has cooled, remove the

spark plug and pour one tablespoonful of lubricating oil of good quality into the cylinder. Crank the engine slowly turning the generator belt by hand to distribut~ the oil over the cyl-

inder walls. Then replace the spark plug.

4. Clean the exterior of the engine.

5. Remove the battery and place it in a cool,

dry place above freezing (+32°F.). Check the

battery at least once a month for water level and amount of charge. See page 19.

6. On the International Cub Cadet 71, 102 and 122 Tractors press the clutch and brake pedal all the way down and engage the brake pedal lock. This will prevent the clutch lining

from sticking to the pressure plate.

7. On the International Cub Cadet 123 Tractors. press the brake pedal all the way

down and engage the brake pedal lock.

REMOVING FROM STORAGE

1. Fill the fuel tank.

2. Install a fully charged battery and be

sure the proper connections are made. See

tltusts. 17 and 17A.

3. Start the engine and let it run slowly.

Do not accelerate the engine rapidly. or op-

erate it at high speed immediately after start-

ing.

Caution! Keep the doors wide open or move

the machine outside the storage room imme-

diately, to avoid danger from exhaust gas.

4. Inflate the tires to the correct operating

pressures. See "Pneumatic Tires" on pages 20

and 21.

5. Release the brake pedal lock.

ENGINE OIL

The tractor is shipped from the factory

with SAE-lOW engine oil in the crankcase. If

the engine is to be operated at temperatures between +75 degrees F and 0 degrees F. this

oil can be used for the first five hours of operation. If the temperatures are not within this range, drain the oil from the crankcase and replace it with new oil as specified in the

"Lubrication Table", The engine oil must be drained and replaced with new oil every 30 hours of engine operation thereafter.

Oils designated "For Service MS" are

recommended for this engine.

To aid starting, the selection of crankcase

lubricating oils should be based on the lowest

anticipated temperature until the next drain

period.

Check the oil levels of the engine crankcase and transmission to see that they are filled to the correct levels. Note: Check the oil level only while the engine is stopped.

MEMORANDA

with

No accident-prevention program can be suc-

cessful without the wholehearted co-operation

of the person who is directly responsible for the operation of equipment.

To read accident reports from allover the country is to be convinced that a large number of accidents can be prevented only by the

operator anticipating the result before the accident is caused and doing something about it. No power-driven equipment, whether it be

transportation or processing, whether it be on the highway, in the harvest field or in the

Accidentsbe

industrial plant, can be safer than the man who is at the controls. If accidents are to be pre-vented

and they can be prevented-it will bedone

by the operators who accept a full measure

of their responsibility.

It is true that the designer, the manufacturer, the safety engineer can help; and they will help, but their combined efforts can be wiped out by a single careless act of the operator.

It is said that' 'the best kind of a safety device is a careful operator. '! We ask you

to be that kind of an operator.
