Filling the Fuel Tank

Fuel Tank Capacity
83 L (22 US gallons)
Fuel Specification
Failure to observe the following cautions may damage
the engine.
•
Never use kerosene or gasoline instead of diesel
fuel.
•
Never mix kerosene or used engine oil with the
diesel fuel.
•
Never keep fuel in containers with zinc plating on
the inside.
•
Do not use fuel additives.
Petroleum Diesel
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.
Use summer-grade diesel fuel (Number 2-D) at
temperatures above -7°C (20°F) and winter-grade
diesel fuel (Number 1-D or Number 1-D/2-D blend)
below -7°C (20°F). Using winter-grade fuel at lower
temperatures provides a 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.
Biodiesel
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:
Biodiesel fuel specification: ASTM D6751 or
EN14214
Blended fuel specification: ASTM D975 or EN590

Biodiesel blends may damage painted surfaces.
Use B5 (biodiesel content of 5%) or lesser blends
in cold weather.
Monitor seals, hoses, and gaskets in contact with
fuel as they may degrade over time.
The fuel filter on your machine might become
plugged for a time after converting to biodiesel
blends.
Contact your authorized Toro distributor for more
information on biodiesel.
Park the machine on a level surface, lower the
cutting units, shut off the engine, and remove
the key.
Using a clean rag, clean the area around the
fuel-tank cap.
Remove the cap from the fuel tank
Figure 33
Fill the tank until the level is to the bottom of the
filler neck with fuel.
Install the fuel-tank cap tightly after filling the
tank.
Note:
If possible, fill the fuel tank after each use.
This minimizes possible buildup of condensation
inside the fuel tank.
