Periodic inspection and adjustment of the engine is essential if
high level performance is to be maintained. Regular maintenance
will also ensure a long service life. The required service intervals

whichever occur first. More frequent service is required when
operating in adverse conditions.
Shut off the engine before performing
any maintenance. To prevent accidental start-up,
disconnect the spark plug boot.

Oil Recommendations
Refer to viscosity chart in Fig. 6-1 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.
NOTE: Do not use non-detergent oil or 2-stroke engine oil. It
could shorten the engine’s service life.
