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).
