BASIC INFORMATION ON THE OPERATION OF FAIRMONT M-19 TYPE MOTOR CARS: LUBRICATING OILS In general the lower viscosity oils give cleaner results, easier starting, and provide a higher factor of safety. Heavy oils have high viscosities and they form excessive carbon and do not flow freely in cold weather. Mixing heavy oil in the gasoline in smaller proportions than recommended reduces the lubricating value of the mixture, and lower engine efficiency and higher maintenance costs will result. S.A.E. 30 oils of approximately the following viscosity characteristics are most satisfactory for year round use. At 130 degrees F - 185 to 255 At 210 degrees F - 50 to 63 Oils up to S.A.E. 40 as follows, may be used if S.A.E. 30 is not available. At 130 degrees F - 255 to 450 At 210 degrees F - 62 to 75 OPERATING THE CAR These instructions apply to direct belt drive cars. The engine will run either forward of backward, but the timer control lever must be set differently for starting and operating in each direction. Forward is with top of flywheel running clockwise as viewed from right side of car or toward front water hopper. Release idler lever, and set and lock the brake. Slip starting crank through steady bearing on right front wheel guard and over end of crank shaft. Apply oil at these points. Retard the spark by moving timer control lever toward the rear of car. Pull up switch button and slowly crank engine forward. The coil should buzz only while the timer contact points close. If it buzzes at any other time or does not buzz at all, there may be a short circuit or improperly connected wire, and a check should be made by following instructions on page 14. Finally open switch (push down). See that shut-off valve at gas tank is open and fuel flows to the carburetor. Partly open the throttle by moving lever toward rear of car. Lever should be about vertical. Be sure ignition switch is open (down), then spin engine several times with crank with choke knob pulled up to choke carburetor. This fills cylinders and crankcase with fresh gas. In cold weather some of the fuel mixture can be injected into priming cups on each cylinder. Choking or priming is usually only necessary when starting a new or cold engine. Be sure spark is retarded, close switch (pull up), and firmly holding the starting crank, quickly pull it upward in a clockwise direction. If engine does not start the first time, continue these upward pulls on the crank until it does, choking again if necessary. When the engine starts, remove the starting crank. [Never spin the engine with switch on, injury might result.] As soon as engine starts, move timer control lever toward the front of the car to advance the spark, and slightly close the throttle so engine runs slowly until it warms up. Push choke partly in and when engine is warm push choke all the way in. Never race a cold engine to warm it up, nor run it at high speed when car is standing still. Backward is with top of flywheel running counter-clockwise when viewed from right side of car, or toward rear water hopper. Retard the spark by moving timer lever toward the front of car. Follow the preceding instructions for testing ignition, setting throttle, choking, and starting, but crank the engine clockwise from the left side of the car. As soon as it starts, move the timer lever toward the rear of the car to advance the spark. To stop the engine, open (push down) the switch. Just before engine stops turning, open throttle to fill the engine with fresh gas and make starting easier. To reverse a battery engine when running, without using starting crank, the belt must be free. Open (push down) ignition switch and leave timer advanced. Open throttle, and just before flywheel stops turning, close (pull up) switch and engine will kick back and run in the opposite direction. Then reset timer lever. Pull out extension lift handles when setting car on and off the track. Be careful not to strike axle pulley on rails. Use care in setting off at crossings, switches, and frogs so axles are not sprung by pinching wheels in flangeways. Always drive with the engine ahead in normal service. After starting and warming up the engine, seat passengers, operator facing ahead, and release brake. Gradually open the throttle and at the same time tighten the belt by slowly pushing idler lever ahead. This allows the belt to slip and act as a clutch. After car gets underway, tighten idler enough to prevent belt slippage, and latch the lever. Use throttle to regulate speed. Timer lever setting should be varied in relation to car speed. As speed is increased, timer should be slowly advanced to point where best operation is obtained. When speed is reduced, timer should be partially retarded. Excessive timer advance may cause engine to misfire. If this occurs, retard timer slightly but do not change carburetor needle valve setting. Always drive a new car slowly and carefully until thoroughly familiar with the controls. A speed of 15 to 20 MPH for the first 500 miles is recommended. If the car loses speed or the engine knocks on hard pulls with open throttle, partially retard the spark, and slip the belt a little if necessary. When coasting down light grades the belt can be released and throttle closed, thereby saving fuel. In descending heavy grades the engine can be used as a brake by leaving belt tight, closing throttle, and cutting off ignition. When coasting long distances, maintain slight throttle opening to furnish lubrication for internal engine parts. To stop the car, first close the throttle, then retard the spark part way. Next release idler lever to slacken belt, and apply the brake. Shut off ignition to stop engine if car is to be removed from track. To reverse a battery ignition car without cranking, release belt and bring car to a full stop, allowing the engine to run slowly. Then reverse the engine as explained previously, after which the car can be driven in the other direction. * END *
