Fill Fuel Tank - Toro Reelmaster 4000-D 03706 Operator's Manual

Caution
If the engine has been running, pressurized hot
coolant can escape and cause burns if the radiator
cap is removed.
Allow the engine to cool at least 15 minutes or until
the radiator cap is cool enough to touch without
burning hands.
2. Check level of coolant in radiator. Radiator should be
filled to the top of the filler neck and the expansion tank
filled to the marks on its side

3. If coolant is low, add a 50/50 mixture of water and
ethylene glycol anti–freeze. DO NOT USE WATER
ONLY OR ALCOHOL / METHANOL BASE
COOLANTS.
4. Install radiator cap and expansion tank cap.

Fill 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.
Fuel tank capacity: 15 U.S. gallons (56.8 l)
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. Remove fuel tank cap (Fig. 6).
2. Fill tank to about one inch (25 mm) below bottom of
filler neck with No. 2 diesel fuel. Then install cap.
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 in. (25 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.
