The fuel system needs to be primed
under certain conditions:
• Before starting the engine for the first time
• After running out of fuel and fuel has been added
to the fuel tank
• After fuel system maintenance such as changing
the fuel filter and draining the water separator, or
replacing a fuel system component.
To prime the fuel system:
1. Turn the key to the ON position for 10 to 15
seconds. This will allow the electric fuel pump to
prime the fuel system.
2. Never use the starter motor to crank the engine
in order to prime the fuel system. This may
cause the starter motor to overheat and
damage the coils, pinion and/or ring gear.
BEFORE YOU OPERATE

ENGINE OIL

• Only use the engine oil specified. Other engine
oils may affect warranty coverage, cause internal
engine components to seize and/or shorten
engine life.
• Prevent dirt and debris from contaminating the
engine oil. Carefully clean the oil cap/dipstick and
the surrounding area before you remove the cap.
• Never mix different types of engine oil. This may
adversely affect the lubricating properties of the
engine oil.
• Never overfill. Overfilling may result in white
exhaust smoke, engine overspeed or internal
damage.
