Changing the Engine Oil
If the engine has been recently run, the
engine, muffler and surrounding metal surfaces will
be hot and can cause burns to the skin. Exercise
caution to avoid burns.
Run the engine for a few minutes to allow the oil in the 
crankcase to warm up. Warm oil will flow more freely and
carry away more of the engine sediment which may have
settled at the bottom of the crankcase. Use care to avoid
burns from hot oil.
Remove the upper star knob and carriage screw on the 2.
