20-Hour Break-In Period

IMPORTANT: The first 20 hours of operation is the engine break-in period. Correct
break-in is essential to obtain minimum oil consumption and maximum engine
performance. During this break-in period, the following rules must be observed:
Do not operate below 1500 rpm for extended periods of time for first 10 hours. Shift into
gear as soon as possible after starting and advance throttle above 1500 rpm if condi-
tions permit safe operation.
Do not operate at one speed consistently for extended periods.
Do not exceed 3/4 throttle during first 10 hours. During next 10 hours, occasional
operation at full throttle is permissible (5 minutes at a time maximum).
Avoid full throttle acceleration from IDLE speed.
Do not operate at full throttle until engine reaches normal operating temperature.
