NOTE: Do not use non-detergent oil or 2-stroke engine oil. It
could shorten the engine's service life.
To avoid engine damage, it is important to:
Check oil level before each use and every 5 operating hours
when the engine is warm.
Change the oil after the first 5 operating hours and every
50 operating hours thereafter. Engine should still be warm
but NOT hot from recent use.
