THE FORD MANUAL


How is the Engine best started in cold weather? Answer No. 8


As gasoline does not vaporize readily in cold weather it is naturally more difficult to start the motor under such conditions. The usual method of starting the engine when cold is to turn the carburetor dash adjustment one-quarter turn to the left in order to allow a richer mixture of gasoline to be drawn into the cylinders; then hold out the priming rod, while you turn crank from six to eight one-quarter turns in quick succession, or turn the motor over a few times with the starter. Another method of starting a troublesome cold engine is as follows: Before you throw on the magneto switch, (1) close throttle lever; (2) hold out priming rod while you give crank several quick turns, or turn the motor over a few times with the starter, then let go of priming rod (being careful that it goes back all the way); (3) place spark lever in about third notch and advance throttle lever several notches; (4) throw on switch (being sure to get it on side marked "Magneto"); (5) give crank one or two turns, or close the starting switch, and the motor should start. After starting the motor it is advisable to advance the spark eight or ten notches on the quadrant and let the motor run until thoroughly heated up. If you start out with a cold motor you will not have much power and are liable to "stall." The advantage of turning on the switch last, or after priming, is that when you throw on the switch and start the motor, you have plenty of gas in the cylinders, to keep the motor running, thereby eliminating the trouble of the motor starting and stopping. After motor is warmed up turn carburetor adjustment back one-quarter turn.

To facilitate starting many drivers make a practice of stopping their engine by pulling out on the priming rod, which has the effect of shutting off the air suction and filling the cylinders full of a very rich gasoline vapor. This should not be done unless that car is going to stand over night or long enough to cool off. If the motor is stopped in this way and then started when hot, starting is apt to be difficult on account of the surplus gasoline in the carburetor.

What function does the Hand Lever perform? Answer No. 9


Its chief purpose is to hold the clutch in neutral position. If it were not for this lever the driver would have to stop the engine whenever he left the drivers seat. He would also be unable to crank the engine without the car starting forward with the first explosion. When pulled back as far as it will go, the hand lever acts as an emergency brake on the rear wheels, by expanding the brake shoes in the rear wheel drums. Therefore the hand lever should be back as far as it will go when cranking the engine or when the car is at rest. It should be only in a vertical position, and not far enough backward to act as a brake on the rear wheels, when the car is to be reversed. When the car is operating in high or low speed the hand lever should be all the way forward.


How do the Foot Pedals operate? Answer No. 10


The first one toward the left operates the clutch. When pressed forward the clutch pedal engages the low speed. When half-way forward the clutch is in neutral (i.e., disconnected from the driving mechanism of the rear wheels), and the releasing of this pedal engages the high-speed clutch. The center pedal operates the reverse. The right-hand pedal operates the transmission brake.

How is the Car started? Answer No. 11


Slightly accelerate the engine by opening the throttle, press the clutch pedal half way forward, thereby holding the clutch in a neutral position while
