Bleeding the Fuel System

You must bleed the fuel system before starting
the engine if any of the following situations have
occurred:
• Initial start up of a new machine.
• Engine has ceased running due to lack of fuel.
• Maintenance has been performed upon fuel
system components (e.g., filter replaced).
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive.
A fire or explosion from fuel can burn you
and others and can cause property damage.
• Use a funnel and fill the fuel tank
outdoors, in an open area, when the
engine is off and is cold. Wipe up any
fuel that spills.
• Do not fill the fuel tank completely full.
Add fuel to the fuel tank until the level
is 1/4 to 1/2 in. (6 to 13 mm) below the
bottom of the filler neck. This empty
space in the tank allows the fuel to
expand.
• Never smoke when handling fuel, and
stay away from an open flame or where
fuel fumes may be ignited by a spark.
• Store fuel in a clean, safety-approved
container and keep the cap in place.
1. Ensure that the fuel tank is at least half full.
