War m the engine at low engine

allows the lubricating 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

2. Warming up the engine
If the engine is operated without water
discharging from the check port, the
engine may over heat.
