Adding Fuel - Toro Wheel Horse 523Dxi Operator's Manual

Adding Fuel

The engine runs on clean, fresh diesel fuel with a
minimum cetane rating of 40. Purchase fuel in
quantities that can be used within 30 days to assure
fuel freshness.
Use summer grade diesel fuel (No. 2–D) at
temperatures above 20 F (–7 C) and winter grade
diesel fuel (No. 1–D or No. 1–D/2–D blend) below
20 F (–7 C). Use of winter grade diesel fuel at
lower temperatures provides lower flash point and
pour point characteristics, therefore easing startability
and lessening chances of chemical separation of the
fuel due to lower temperatures (wax appearance,
which may plug filters).
Use of summer grade diesel fuel above 20 F (–7 C)
will contribute toward longer life of the pump
components.
IMPORTANT: Do not use kerosene or
gasoline instead of diesel fuel. Failure to
observe this caution will damage the engine.
POTENTIAL HAZARD
Under certain conditions, fuel is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
A fire or explosion from fuel can burn you,
others, and cause property damage.
HOW TO AVOID THE HAZARD
Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine 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" (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows 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 an approved container and
keep it out of the reach of children. Never
buy more than a 30-day supply.
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
lower the attachment lift, and turn the ignition
key to "STOP" to stop the engine. Remove the
ignition key.
2. Clean around the fuel tank cap and remove the
cap. Use a funnel and add fuel until the fuel
level is 1/4 to 1/2 inch (6 mm to 13 mm) below
the bottom of the filler neck. This space in the
tank allows for expansion of the fuel. When
filling the tank, make sure that the machine is on
a level surface so that adequate air space is
allowed. Do not fill the fuel tank completely.
3. Install the fuel cap securely. Wipe up any fuel
that may have spilled.
4. If possible, fill the fuel tank after each use. This
will minimize possible buildup of condensation
inside the fuel tank.
