engines/equipment certified to California standards) requires that this engine/equipment complies with exhaust and
evaporative emissions standards. Locate the emissions compliance decal on the engine to determine applicable
standards. For emissions warranty information, please reference the included emissions warranty. It is important to

FUEL SYSTEM
Note: The ignition is factory set to 18° BTDC.
Verify timing set correctly to 18° BTDC. Failure to do so could result in irreparable damage
to the unit.
This is a dual-fuel generator, capable of running on either natural gas—wellhead or refined (NG), or propane liquid
(LPL). The unit runs on either fuel source, but never simultaneously. Each fuel source is connected to an independent
fuel system. Fuel switching occurs automatically and during unit operation—no operator action is required. For more
information, see Fuel Switching.
ALL FUEL TYPES ARE POTENTIALLY FLAMMABLE AND/OR EXPOSIVE AND
SHOULD BE HANDLED WITH CARE. COMPLY WITH ALL LAWS REGULATING THE
STORAGE AND HANDLING OF FUELS.
