5-2 Warming up the engine
Warm the engine at low engine speeds for about three minutes. This
allows the lubricating oil to circulate to all parts of the engine. Oper-
ating the engine without warming it up shortens the engine's life.
Be sure to check that cooling water is coming out of the water check
port when warming up the engine.
Note:
If the engine is operated continuously without water discharging from
the check port or idle hole, the engine may heat over.
