should be put into the upper crankcase tray and five quarts in the reservoir.
The quantity of oil in the reservoir can be determined by the bayonet gauge
attached to the filler cover. (See Figure 2.) When the oil level is down to the low
mark, one inch from the bottom of the gauge, three quarts of oil remain in the
reservoir. Two additional quarts are required to bring the level up to the high
mark at the top of the oil level gauge. When the reservoir only is drained by
removal of the drain plug at the rear of the reservoir, five quarts of oil should be
used, filling through the opening in the left side of the crankcase. (See Figure 2.)
The red jewel mounted to the right of the center of the instrument group should
be lighted when the ignition is turned on but go out when the engine is running at
slightly more than idling speed. Flashing of the light at idling speed indicates
proper operation. Should the light come on when the engine is running above
idling speed it indicates interruption of the oil supply and the engine should be
stopped until the cause is corrected
Lubricants
It is important that the proper lubricants be selected to give protection to the
working parts and at the same time provide free movement of the parts at the
lowest temperature encountered. The following recommendations should be
adhered to strictly.
Use a good quality oil as specified for the lowest atmospheric temperature en-
countered, as follows:
Atmospheric Temperature Oil Specification
40° Fahrenheit and higher S. A. E. 30
40° to 0° Fahrenheit 20 W.
0 ° to —
15º
Fahrenheit 10 W.
Below—15 ° Fahrenheit 10 W.+10% Kerosene
The oil level should be maintained within the
"oil
level range" on the oil level
gauge at all times. Drain oil after first 500 miles of operation and at 2,000-mile
intervals thereafter. Refill with five quarts of oil of proper specification
