Adding Fuel

Recommended Fuel
The engine runs on clean, fresh diesel fuel with
a minimum cetane rating of 40. Purchase fuel in
quantities that can be used within 30 days to ensure
fuel freshness.
Use summer-grade diesel fuel (No. 2-D) at
temperatures above -7°C (20°F) and winter-grade
diesel fuel (No. 1-D or No. 1-D/2-D blend) below
-7°C (20°F). Use of winter-grade diesel fuel at lower
temperatures provides lower flash point and pour
point characteristics, therefore easing startability and
lessening chances of chemical separation of the fuel
due to lower temperatures (wax appearance, which
may plug filters).
Using summer-grade diesel fuel above -7°C
(20°F) contributes toward longer life of the pump
components.
Important:
Do not use kerosene or gasoline
instead of diesel fuel. Failure to observe this
caution will damage the engine.
Biodiesel Ready
This machine can also use a biodiesel blended fuel
of up to B20 (20% biodiesel, 80% petrodiesel). The
petrodiesel portion should be ultra low sulfur.
Observe the following precautions:
•
The biodiesel portion of the fuel meet specification
ASTM D6751 or EN14214.
•
The blended fuel composition should meet ASTM
D975 or EN590.
•
Painted surfaces may be damaged by biodiesel
blends.
•
Use B5 (biodiesel content of 5%) or lesser blend
in cold weather.
•
Monitor seals, hoses, gaskets in contact with fuel
as they may degrade over time.
•
Fuel filter plugging may be expected for a time
after converting to biodiesel blends.
•
Contact your distributor for more information on
biodiesel.
Filling the Fuel Tank
1. Park the machine on a level surface.
2. Engage the parking brake.
3. Shut off the engine and remove the key.
4. Clean around the fuel-tank cap.
5. Fill the fuel tank to the bottom of the filler neck
(Figure 9).
Note:
Do not fill the fuel tank completely full.
The empty space in the tank allows the fuel to
expand.
Performing Daily
Maintenance
Before starting the machine each day, perform the
Each Use/Daily procedures listed in
(page 40).

Breaking in a New Machine

New engines take time to develop full power. Mower
decks and drive systems have higher friction when
new, placing additional load on the engine. Allow
40 to 50 hours of break-in time for new machines to
develop full power and best performance.
