Adding Fuel
Fuel Specication
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 ash point and cold ow characteristics
which eases starting and reduces fuel lter 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 specication: ASTM D6751 or
EN14214
Blended fuel specication: 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.
• 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 lter plugging may occur for period after
converting to biodiesel blends.
• Contact your authorized T oro distributor if you wish
for more information on biodiesel.
Filling the Fuel T ank
Fuel tank capacity: 45 L (12 US gallons)
Note: If possible, ll the fuel tank after each use; this
minimizes condensation buildup inside the fuel tank.
1. Park the machine on a level surface ( Figure 32 ),
engage the parking brake, shut of f the engine,
and remove the key
2. Unscrew the cap from the fuel tank.
3. Fill the fuel tank with the specied fuel until the
fuel-gauge dial indicates that the tank is full.
4. Screw the cap onto the fuel tank.
