TO START VEHICLE.

 

Release hand brake, if set. 

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 "clashin

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 pedal. 

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 of speed. 

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.
