following:
1.
Sit in the operator's seat.
2.
Engage the parking brake.
3.

Adding Fuel
Use only clean, fresh diesel fuel or biodiesel fuels with
low (<500 ppm) or ultra low (<15 ppm) sulfur content.
The minimum cetane rating should be 40. Purchase
fuel in quantities that can be used within 180 days
to ensure fuel freshness.
Fuel tank capacity: 41 L (10.8 US gallons)
Use summer-grade diesel fuel (No. 2-D) at
temperatures above -7°C (20°F) and winter-grade
(No. 1-D or No. 1-D/2-D blend) below that
temperature. Using winter-grade fuel at lower
temperatures provides lower flash point and cold flow
characteristics which will ease starting and reduce
fuel filter plugging.
Using summer-grade fuel above -7°C (20°F) will
contribute toward longer fuel pump life and increased
power compared to winter-grade fuel.
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 low or ultra low sulfur.
Observe the following precautions:
•
The biodiesel portion of the fuel must meet
specification ASTM D6751 or EN14214.
•
The blended fuel composition should meet ASTM
D975 or EN590.
•
If you spill biodiesel fuel blends, the fuel may
damage painted surfaces.
•
Use B5 (biodiesel content of 5%) or lesser blends
in cold weather.
•
Monitor the seals, hoses, and gaskets in contact
with fuel as they may degrade over time.
•
Expect fuel filter plugging for a time after converting
to biodiesel blends.
•
Contact your authorized Toro distributor if you
want more information on biodiesel.
