4. Warming up the engine

Warm the engine at low engine speeds for
about three minutes. This allows the lubri-
cating oil to circulate to all parts of the
engine. Operating the engine without
warm up shortens the engine's life.
Be sure to check that cooling water is
coming out of the cooling water check
port during warm up.
