3. Access to rotate the engine by hand is available by:
a. Removingthe engine intake screen in the battery
compartment such that the crankshaft nut is accessible.

Engine Oil
The engine is filled with synthetic oil (API SJiCF5W-30).
This allows for system operation in the widest range of
temperature and climate conditions.
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SJ or
higher. DO NOT use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
NOTICE Synthetic oil meeting ILSACGF-2, API
certification mark and API service symbol with "%/
CF ENERGYCONSERVING" o r higher, is an
acceptable oil at all temperatures. Use of synthetic
oil does not alter required oil change intervals.
