Engine
WARNING
If the engine has been running, the muffler, engine head and spark plug
will be very hot. Be careful not to touch any of these components until they
have cooled.
Oil Recommendations
Refer to the viscosity chart (Figure 22) for oil recommendations. Do not over-fill.
Use a 4-stroke, or an equivalent high detergent, premium quality motor oil certified
to meet or exceed U.S. automobile manufacturer’s requirements for service
classification of a minimum level SF or SG (higher letter ratings are acceptable such
as SJ, SL and SM grades). Motor oil will display this designation on the container.
Figure 22
NOTE:
Do not use non-detergent oil or 2-stroke engine oil. It could shorten
the engine’s service life.
