Avoid Accidents
Most accidents, whether they occur in industry, on the farm,
at home, or on the highway, are caused
by the failure of some
individual to follow simple and fundamental safety rules or
precautions. For this reason most accidents can
be prevented
by recognizing the real cause and doing something about it before
the accident occurs.
Regardless of the care used in the design and construction of
any type of equipment, there are many conditions that cannot
be
completely safeguarded against without interfering with reasonable
accessibility and efficient operation.
A careful operator is the best insurance against an
accident.
The complete observance of onc?simple rule would pre-
vent many thousand serious injuries each year. That rule
is: C'Nenerattempt to clean,oil, or adjust a machine while
it is
in motion."

OPERATING PRECAUTIONS
Read Instruction Book carefully.
Follow 'Lubricatton,Chart.
"
Before cranking tractor engine, be sure:-
I. Gear shift lever is in neutral position.
2. Radiator is filled with water.
3. Englne has sufficient oil in crankcase pan.
When cranking the engine, retard spark control. Operator
should take his position so as to avotd being struck by starttng crank
if there is a reversal of the direct ion of the engine from any cause
whatsoever.
Khen starting the Tractor always engage clutch gradually. so engtne will
pick up the load slowl~.This is parttcularly necessary when going up
a steep hill, cl imbtng out of ditches or when hitched to a heavy or
difficult lood. Never hitch to a stump or other object by means of a
lbnC chain or rope with slack so that when Tractor moves forward it will
jerk into the lood.
Never operate engtne at more than the regu
speeds are dangerous.

MANIFOLD HEAT CONTROL
Para. Illust .
20 3 Push the manifold heat control lever on left side of
fuel tank forward all the way. This sets the heat
control valve on manifold, in "Hotn
or starting posi-
tion.
It ts important that control lever be properly
set to correspond with fuel being used and operating
conditions.
When starting on gasoline and operating.on distillate,
it will be desirable to keep the valve in "Hot"
position most of the time unless the weather is very
hot. In hot weather with a heavy load on the
engine, good results may be obtained with this valve'
in intermediate or "Cold11 position, but generally,
better results
will be secured if the intake manifold
is kept hot when using distillate. If not kept hot,
fuel
will not be properly vaporized and dilution of
the crankcase lubricating oil, as well as imperfect
regulation of engine will result.

are below 3Z0

use of choke for starting
will vary depending on temper-
ature and altitude.
Do not use choke to enrich fuel mixture except when
starting the engine.

As soon as engine starts, the choke should be adjusted
to where the engine runs without missing,
and as the
engine warms up the choke should be gradually opened
all the way.

EilGINE SPEED CONTROL
Since the governor maintains constant engine speed
under variable loads, the engine speed control hand
lever should be used only to reduce the speed of
the engine below normal operating speed; with
engine speed control hand lever retarded, very
little load can be handled by the engine.
AFTER ENGINE IS WARMED UP
35 3 After engine is thoroughly warmed up, change over
to operate on distillate by closing gasoline shut-
off valve tight, and quickly open distillate
valve.
Never have both valves .open, or partly open, at the
same tine, otherwise distillate wtl2 mix with gaso-
line, making
it unsatisfactory for starting.

HOT SPOT MANIFOLD - DISTILLATE OPERATION
A full range of mixture temperatures is available by changing the setting of
the heat control valve on the hot spot manifold. The engine should never be
operated on kerosene
or distillate rith the valve in all "Cold* position. At
normal air temperatures, the valve should be in 1/2 to 3/4 "Hotmwhen operat-
ing on
kerosene or distillate. At loner temperatures, 50° to 35' , the valve
should be 3/4 to full "Hot".
At loner temperatures, the valve shaold be in
full "Hot" positlon and the winterfront closed. For
satisfactory cold weather
operation on distillate, the winterfront must be closed, the amount depend-
ine on load

NOTE:
Periodically check the screw fastening the fuel bow1 to fuel boy1

HOT SPOT MANIFOLD - GASOLINE DPERATION
A full range of mixture temperatures is available by changing the setting
of the heat control valve on the hot spot msnifold. Satisfactory gasoline
operation
can be obtained with the heat valve set in "Cold' position. When
starting
s ~016engine, it is advisable to set heat control valve in "Hot"
position and chsnge to "Cold" position when engine is wzrmed up.

ENGINE SPEED CONTROL LEVEfi
The lever on the left hand side of the fuel tank is the engine speed
control lever.
The rated or governed speed is 1650 R.P.M. for full load, which gives
a fast idling (no-load)
speed of approximately 1800 R.P.M.
Inportant!
Por all-round satlsfoctory operatlon. the engine should
not be ldlad down to
a speed below 300 to 400 R.P.I.
GOVERNOR CONTROL ADJUSTEIENT
The governor is set at the factory and should require no adjustaent.
STEERING AND BRWLES
The brakes take hold when the front wheels are swung to the extreme
right or left, thus czusing either of the rear wheels to lock, and the
tractor to pivot in its course
of travel. The question as to which
rear wheel locks depends on the direction of steering; for exemple,
when front wheels are turned to left, the left rear wheel lacks and
tractor pivots
to the left.
TO
STOP TRACTOR
Disengage clutch by pressing down firmly on clutch pedal, then move
gear shifting lever to neutral position.
Use the brakes if necessary.
SnFETY FIRST:- Stop power Coke-off before dismounting from tractor.
Be sure gear shift lousr ts 1" neutral posltlon before
dlsmountlng from tractor.

COLD WEATHER OPERATION
If Tractor is to be operated when temperature is below 32O F.
certain
protective precautions are necessary.
Use "Wintern engine and transmission lubricants.
(Sea "Lubrtcatlon
Chart").
Use a good grade of engine oilhaving the proper body, with
a loa
cold test, suitable for existing climatic conditions.
Use kerosene in magneto coupling.
- -
Transmission oil must be light enough to flow in prevailing atmosphere
temperature. If transmission lubricant available
is too heavy dilute
sufficiently with lighter oil so
it will flow readily.
Failure of transmission lubricant to flaw readily
will soon cause
bearings to be without oil.
ENGINE STARTING
Have oil in engine crankcase light enough that engine will not be too
stiff to crank.
If desired, during very cold weather, the engine oil in the crankcase
pan
can be completely drained each night. Do this while the oil is
warm so
it will drain freely.
Before refilling, warm ail thoroughly and pour into crankcase just
before starting the engine, as this
will insure oil thin enough to
pass through screen over pump suction, also preventing condensation of
moisture in crankcase pan.
Filling fuel tank at end
of day's run wil1,prevent moisture from
collecting in the tank.
Use
a high test winter grade of gasoline for starting.
If engine has been idle far any length of time check crankcase pan,
fuel tank and fuel bawl for any ice formation before starting.
If trouble is experienced, see .Correclloe Xeasures', pale 33. also
