Final Installation Considerations

Engine Oil
NOTICE Any attempt to crank or start the engine before it
has been properly serviced with the recommended oil will
result in equipment failure.
Refer to Maintenance in the operator's manual for oil
fill information.
Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
The engine is shipped from the factory pre-run and filled
with synthetic oil (API SJ/CF 5W-30). This allows for system
operation in a wide range of temperature and climate
conditions. Before starting the engine, check oil level and
ensure that engine is serviced as described in Maintenance
of the Operator's Manual.
The use of synthetic oil does not alter the required oil
change intervals described in the Operator's Manual.
