Adding Fuel - Toro Groundsmaster 3500-D Operator's Manual

•
Do not store the machine or fuel container where
there is an open flame, spark, or pilot light, such
as on a water heater or other appliance.
•
If you spill fuel, do not attempt to start the engine;
avoid creating any source of ignition until the fuel
vapors have dissipated.

Adding Fuel

Recommended 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.
Important:
Use of non-ultra low sulfur fuel
causes damage to the engine emission system.
Fuel tank capacity: 42 L (11 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. Use of winter-grade fuel at lower
temperatures provides lower flash point and cold-flow
characteristics, which eases starting and reduces fuel
filter plugging.
Use of summer-grade fuel above -7°C (20°F)
contributes 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 damages the engine.
Using Biodiesel
This machine can also use a biodiesel-blended fuel of
up to B20 (20% biodiesel, 80% petrodiesel).
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.
•
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 a time after you
convert to biodiesel blends.
•
For more information on biodiesel, contact your
authorized Toro distributor.
