TO MAKE VEHICLE READY.
Fill the radiator with clean, soft water.
Put gasoline in the tank.
Fill the oil reservoir through the filler pipe at the right side of the
engine until the oil indicator stick registers “FULL”. (See “Lubrication
Supply all parts requiring lubrication with oil or lubricant.
See that the tires have proper pressure (See “Tire Pressure”.)
Adjust the rear view mirror to correct position for driver. If adequate
view is not obtainable, the mirror may be adjusted by loosening the screw
through the mounting bracket or by tilting in the ball and socket connection.
CONTROLS AND SWITCHES.
The position of all controls and switches is shown in Fig. 1.
The horn is operated by pressing the button located at the top center of
the steering wheel.
The instrument panel light switch is located along the lower edge of the
instrument panel to the left of the steering post. The windshield
wiper control is mounted on the wiper motor housing.
The main light switch No. 30 controlling both the head and tail lamps is
conveniently located on the instrument panel to the left of the steering
post. It is of the plunger type – pull all the way out for the “full
on” position, half-way for “parking” and all the way in is the “off” position.
In addition to the main light switch, the high and low beams of the headlamps
are controlled by a selector foot switch, located on the toe board to the
left of the clutch pedal. Pressing and releasing the switch button,
with the foot, alternately changes the beam from high to low and vice versa.
TO START ENGINE.
Put the transmission gearshift lever No. 21, Fig. 1 in neutral. Place
the transfer case low and high shift lever No. 19 in direct gear or in
the rear position and disengage the front axle by placing the shift lever
No. 29 in the forward position.
Pull the choke control button No. 13 one-fourth of the way out which also
opens the throttle slightly.
Place the key in ignition lock No. 17 and turn it to the right, closing
the ignition circuit.
Disengage the clutch.
Depress the foot starting switch at No. 18.
Should the engine fail to start at once, pull the choke all the way out
and press the starting switch. When the engine starts, push the choke
in about one-third of the way.
Set the choke control at the best operating position and as the engine
warms up, push the choke all the way in. Do not run with the choke
out as fuel is wasted and the engine fouled.
Should the engine fail to start, see the “Emergency Chart”.

TO START VEHICLE.
Release hand brake,
Depress clutch pedal.
Move transmission gearshift leer to first speed position – see Fig. 3 (Note
that the front axle and transfer case shift levers are not used when the
vehicle is driven on the highway in rear wheel drive.)
Depress the foot accelerator pedal gradually and at the same time, slowly
release the clutch pedal.
Allow the vehicle to gain momentum (two or three vehicle lengths), then
release the accelerator and depress the clutch at the same moment.
Move the shift lever promptly to the second speed position.
Depress the foot accelerator pedal gradually and at the same time, slowly
release the clutch pedal.
Shift to third or "high" speed in the same way at approximately 18 to 20
mph, releasing the accelerator and depressing the clutch before moving
the shift lever.
The synchronizing mechanism in the transmission makes gear shifting silent
and easy. This device adjusts the speeds of the two gears to be engaged
and prevents "clashing".
TO CHANGE TO LOWER SPEED.
Depress the clutch pedal.
Move the gearshift lever quickly to the next lower speed, increasing the
engine speed slightly, if traveling on level road and release the clutch
It will be found advisable to make this change when the engine is placed
under heavy pull, or when dropping down to a very low speed, as when travelling
up a steep grade, in sand or in congested traffic.
Never attempt to make the change with the vehicle traveling at a high rate
TO STOP THE VEHICLE.
Release the foot accelerator.
Depress the clutch pedal and apply foot brake.
When stopped, move gearshift lever into neutral.
Set the hand brake and release the clutch and brake pedals.
TO REVERSE VEHICLE.
With the vehicle at a standstill, depress the clutch pedal.
Shift the lever into the reverse position, slowly release the clutch pedal
and regulate the car speed with the foot accelerator.
TO USE THE ENGINE AS A BRAKE.
The most effective brake for holding the vehicle back on a steep grade
is the engine. To use the engine as a brake, shift into one of the
lower speeds before starting to descend. Keep the clutch engaged,
the throttle closed, and the ignition “ON”. Low gear will hold any
vehicle effectively on any hill it can climb.
Never engage the clutch suddenly when the vehicle is coasting with
the clutch released and the transmission gears in mesh, as damage to the
driving mechanism may result.

STARTING VEHICLE ON UPGRADE.
In starting on an upgrade, hold the vehicle with the hand brake, disengage
the clutch and shift the transmission into low speed, then accelerate the
engine with the foot accelerator in the regular way while simultaneously
releasing the hand brake and engaging the clutch
SHIFTING GEAR IN TRANSFER CASE.
The transfer case is essentially a two speed transmission, which provides
a low and a direct gear and also a means of connecting the engine power
to the front axle. It is an auxiliary unit attached to the rear of
the standard transmission.
Control of the transfer case is through the two shift levers, Fig. 1
No. 19 and No. 20. The left lever, No. 20, is used to connect and
disconnect the power to the front axle. The right lever, No. 19 is
used to shift the transfer case gears to secure either “High” (direct drive)
or a very low gear ratio for heavy pulling requirements.
Instructions for shifting gears in the transfer case are as follows:
See Fig. 3.
1. To engage front axle drive, depress the clutch pedal, release accelerator
and move the left hand shift lever (No. 20) to rear position
2. With the front axle drive engaged, the right hand lever (No. 19) may
be shifted to the rear into “High” (direct) or forward into “Low”.
The “Neutral” position midway between “High” and “Low” is for use when
the power take-off belt drive is used. The vehicle cannot be driven
when this lever is in “Neutral”.
3. To disengage the front axle drive, depress the clutch pedal, release
the accelerator and shift the left lever to the forward position.
The transfer case can be operated only in “High” (direct drive) when the
front axle drive is disengaged.
4. Shifting from high to low transfer case gear should not be attempted
except when the vehicle is practically at a standstill. The front
axle drive must be engaged for this shift. Release the accelerator
and depress the clutch pedal – move the left hand shift lever to the rear
position to engage the front wheel drive, then move the right hand shift
lever to forward position (low transfer case gear).
5. Shifting from low to high transfer case gear may be accomplished at
any time, regardless of vehicle speed. Release accelerator and depress
clutch pedal and shift right hand lever into rear position.
USE OF FOUR WHEEL DRIVE.
The “Universal Jeep” is equipped with four-wheel drive and transfer
case to provide additional traction and a low gear ratio for use on difficult
terrain and to provide low speed pulling power for industrial and agricultural
use. Four-wheel drive should be used only when greater traction and
power are required than provided by the standard transmission and low gear.
Avoid the use of four-wheel drive on hard surfaced highways as it will
result in rapid tire wear and hard shifting of the transfer case gears.
Should hard shifting occur, disengage the clutch, start engine, shift the
transmission into reverse gear, back the vehicle a few feet, and disengage
the clutch. If transfer case is in low range, shift into high, then
disengage front axle drive (left lever forward).
STEERING KNUCKLE OIL SEAL.
parking during cold, wet weather, swing the front wheels from right to
left to wipe away moisture adhering to the front axle universal joint housings
and oil seals, Fig. 5. This will prevent freezing with resulting
damage to the oil seal felts. When the vehicle is stored for any
period, the front axle universal joint housings should be coated with light
grease to prevent rusting.
How to Save Gasoline
1. In cold weather economical starting of the engine is easily obtained
by pressing down on the accelerator pedal once or twice, then push down
on the clutch pedal and start engine using the choke sparingly. Do
not use the choke when starting a warm engine.
2. Do not use the choke excessively while engine is warming up and never
leave it out longer than absolutely necessary.
3. Accelerate gently. Tramping on the accelerator pumps more gasoline
into the cylenders than can be effectively used.
4. Holding the car in second gear until you get up to high speeds may easily
double the gasoline you should use in getting under way. Shift into
high gear at about 20 miles per hour.
5. Fast driving uses up more gasoline. Travel at moderate speeds
if you want gasoline economy.
6. Decelerate to a gradual stop. Sudden stops, like sudden starts,
are wasteful of gasoline.
7. Park your car in the shade if possible, hot sun evaporates gasoline.
8. Don't drive your tires with less than the proper amount of air pressure.
Under-inflated tires mean more road friction, more work for the engine
to do -- and therefore more gasoline consumed. See "Tire Pressure".
9. Keep the battery charged up in good condition. It helps starting
and provides good ignition thereby reducing loss of gasoline.
10. Letting the engine idle for long periods wastes gasoline.
11. Be sure that the carburetor is in proper condition for maximum mileage
12. One faulty or dirty spark plug may waste as much as 10 percent of your
gasoline. Have the spark plugs tested occasionally.
13. Keep your car well lubricated at all times, and be very careful to
follow the instructions on "Lubrication".
14. Keep the radiator filled to the proper level; your engine will remain
at a more constant temperature. An overheated engine uses more gasoline.
15. Check the operation of the automatic heat control on the exhaust manifold.
The purpose of this heater is to warm the mixture of air and gasoline as
it leaves the carburetor, in order to give better vaporization. (See
Manifold Heat Control).
16. It is a good idea to have a complete engine tune-up every 5,000 miles,
or at least twice a year -- in the Fall when preparing for Winter driving
and again in the Spring. The Owner Service Policy entitles you to
an adjustment and complete inspection without charge at the end of
the first 1000 miles.
