Fuel System
Maintenance
DANGER
Under certain conditions, 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 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 25 mm (1 inch)
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 fuel
container and keep the cap in place.

Connections
Service Interval: After the first 50 hours
Every 400 hours/Yearly (whichever comes first)

before operating the machine.
