Filling The Fuel Tank - Toro 30839 Operator's Manual

3. Push the dipstick down into the dipstick tube and
make sure that it is seated fully. Pull the dipstick out
and check the oil level.
4. If the oil level is low, remove the oil fill cap
(Figure 21) and gradually add small quantities of oil,
checking the level frequently, until the level reaches
the Full mark on the dipstick.

Filling the Fuel Tank

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.
The fuel tank capacity is approximately 11 gallons (42
liters).
Use summer grade diesel fuel (No. 2–D) at
temperatures above 20 degrees F (–7 degrees C) 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 will ease starting and reduce fuel
filter plugging.
Use of summer grade fuel above 20 degrees F (-7
degrees C) will contribute toward longer fuel pump life
and increased power compared to winter grade fuel.
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.
• Painted surfaces may be damaged by biodiesel
blends.
• Use B5 (biodiesel content of 5%) or lesser blends
in cold weather
• Monitor seals, hoses, gaskets in contact with fuel as
they may be degraded over time.
• Fuel filter plugging may be expected for a time after
converting to biodiesel blends.
• Contact your distributor if you wish for more
information on biodiesel
1. Clean the area around the fuel tank cap (Figure 22).
2. Remove the fuel tank cap.
3. Fill the tank to the bottom of the filler neck. Do
not overfill. Install the cap.
4. To prevent a fire hazard, wipe up any fuel that may
have spilled.

DANGER
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A
fire or explosion from fuel can burn you and
others and can cause property damage.
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is off and
is cold. Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is 1/4 to
1/2 inch (6 to 13 mm) below the bottom of
the filler neck. This empty space in the tank
allows the fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in a clean, safety-approved
container and keep the cap in place.
