Fuel System
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.
• 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 25 mm (1 inch)
below the top of the tank, not 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.

Draining the Fuel Tank

Service Interval: Every 800 hours
Before storage
Park the machine on a level surface, lower the cutting units,
engage the parking brake, shut off the engine, and remove
the key.
Drain and clean the fuel tank if the fuel system becomes
contaminated or if the machine is to be stored for an extended
period. Use clean fuel to flush out the tank.
Checking the Fuel Lines and
Connections
Service Interval: Every 400 hours/Yearly (whichever comes
first)
Park the machine on a level surface, lower the cutting units,
engage the parking brake, shut off the engine, and remove
the key.
Inspect the fuel lines for deterioration, damage, or loose
connections.

canister.
Cleaning the Fuel-Intake
Screen
Park the machine on a level surface, lower the cutting units,
engage the parking brake, shut off the engine, and remove
