2. The engine should be pre-oiled before
startup. Crank the engine, leaving the fuel
system shut off so the engine will not start, for
15 seconds. Then pause for 30 seconds.
Repeat the procedure until you have cranked
the engine for a total of one minute. This will
circulate the oil in the engine's lubrication
system.
