Product Manual

General Information
6 Owner’s Manual for Spark-Ignited Stationary Generators
NOTE: A complete specification sheet is included in the
documentation provided with the unit at the time of pur-
chase. Contact an IASD for additional copies.
Engine Oil Recommendations
To maintain the product warranty, engine oil should be
serviced in accordance with the recommendations of this
manual. For your convenience, maintenance kits
designed and intended for use on this product are avail-
able from the manufacturer that include engine oil, oil fil-
ter, air filter, spark plug(s), a shop towel, and funnel.
These kits can be obtained from an IASD.
Although the unit is filled at the factory with 5W-20 engine
oil, replace with 5W-30 semi-synthetic blend engine oil at
the first oil change, which is due at 25 hours break-in.
Select a high-quality detergent oil classified “SJ or SH.”
Detergent oils keep the engine cleaner and reduce car-
bon deposits. After break-in, a synthetic oil that meets or
exceeds SAE specifications is recommended. Once syn-
thetic oil is used, it should be used for the life of the gen-
erator. It is not recommended to go back to a mineral oil.
Do not use special additives.
NOTE: If not already equipped, it is strongly recom-
mended to use the optional Cold Weather Start Kit for
temperatures below 32 °F (0 °C). The oil grade for tem-
peratures below 32 °F (0 °C) is 5W-30 synthetic oil.
