Tenth.—Run the motor until it is warm. If any weakness in compression is noticeable the cylinders are probably scored, or the rings may be worn. The valves may also be warped, thereby preventing them from seating properly.
Eleventh.—Examine the shoulders of the cross-members supporting the engine, radiator, or transmission to see if they are cracked or broken.
Twelfth.—The battery may have deteriorated through improper attention. Test the solution with a hydrometer. If it is found well up, it can be passed as O. K.
Thirteenth.—Don’t judge the condition of the car by the model, as a two or three-year-old model may be in better mechanical condition than a six-month or year-old model.
DRIVING INSTRUCTIONS
A new driver should remain cool and take things in a natural way as a matter of course. There is nothing to get nervous or excited about when learning to drive a car. Any one can master the art of driving quickly by remaining cool and optimistic.
First.—Acquire some definite knowledge of the operation of the engine and its accompanying devices.
Second.—Have some one explain the operation of the accelerator, spark, and throttle levers.
Third.—Study the relative action of the clutch and gear-shifting pedal.
Fourth.—The new driver takes the wheel and assumes a natural and calm position with the muscles relaxed.
