Adding Fuel

Fuel Specification
Important:
Use only low sulphur or ultra-low
sulphur diesel fuel.
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.
•
Use only clean, fresh diesel fuel or biodiesel fuels.
•
Purchase fuel in quantities that you can use within
180 days to ensure fuel freshness.
Petroleum Diesel
Cetane rating: 40 or higher
Sulfur content: Low sulphur (<500 ppm) or ultra-low
sulfur (<15 ppm)
Use summer-grade diesel fuel (No. 2-D) at
temperatures above -7°C (20°F) and winter-grade
fuel (No. 1-D or No. 1-D/2-D blend) below that
temperature.
Note:
Use of winter-grade fuel at lower temperatures
provides lower flash point and cold flow characteristics
which eases starting and reduces fuel filter plugging.
Using summer-grade fuel above -7°C (20°F)
contributes 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% petroleum diesel).
Sulfur content: Ultra-low sulfur (<15 ppm)
Biodiesel fuel specification: ASTM D6751 or
EN14214
Blended fuel specification: ASTM D975, EN590,
or JIS K2204
Important:
The petroleum diesel portion must
be ultra-low sulfur.
Observe the following precautions:
•
Biodiesel blends may damage painted surfaces.
g001055
•
Use B5 (biodiesel content of 5%) or lesser blends
in cold weather.
•
Monitor seals, hoses, gaskets in contact with fuel
as they may degrade over time.
•
Fuel filter plugging may occur for period after
converting to biodiesel blends.
•
Contact your authorized Toro distributor if you wish
for more information on biodiesel.
Filling the Fuel Tank
Fuel tank capacity: 45 L (12 US gallons)
Note:
If possible, fill the fuel tank after each use; this
minimizes condensation buildup inside the fuel tank.
1. Park the machine on a level surface
engage the parking brake, shut off the engine,
and remove the key
2. Unscrew the cap from the fuel tank.
3. Fill the fuel tank with the specified fuel until the
fuel-gauge dial indicates that the tank is full.
4. Screw the cap onto the fuel tank.
