Note: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system oil is available in 2/3 oz. (20 ml)
bottles. One bottle is sufficient for 4–6 gal (15–22 1)
of hydraulic oil. Order part no. 44–2500 from your
authorized Toro distributor.
1. Position machine on a level surface. Place all control
in neutral position and start the engine. Run engine
at lowest possible RPM to purge the system of air.
DO NOT ENGAGE PTO. Cycle steering wheel
several times fully to the left and right. Raise the
deck to extend lift cylinders, aiming steering wheels
straight forward and stop the engine.
2. Remove dipstick cap (Figure 23) from filler neck
and wipe it with a clean rag. Screw dipstick cap
finger-tight onto filler neck; then remove it and
check level of fluid. If level is not within 1/2 inch
(13 mm) from the groove in the dipstick (Figure 23),
add enough high quality hydraulic fluid to raise level
to groove mark. Do not overfill.

3. Thread dipstick fill cap finger-tight onto filler neck.
It is not recommended to tighten cap with a wrench.
4. Check all hoses and fittings for leaks.
Filling the Fuel Tank
Fuel tank capacity is approximately 12.8 gallon (48.5 l).
1. Using a clean rag, clean area around fuel tank cap.

3. Fill the tank until the level is to the bottom of the
filler neck with unleaded fuel.
4. Install fuel tank cap tightly after filling tank.
Under certain conditions, 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 to the
bottom of the filler neck.
• 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.
