Maintenance
DANGER
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 6 to 12 mm
(1/4 to 1/2 inches) 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.
