Industry Specifications:
Vickers I-286-S (Quality Level), Vickers M-2950-S
(Quality Level), Denison HF-0
Important: The ISO VG 46 Multigrade fluid has been
found to offer optimal performance in a wide range of
temperature conditions. For operation in consistently
high ambient temperatures, 65° F (18° C) to 120° F
(49° C), ISO VG 68 hydraulic fluid may offer improved
performance.
Premium Biodegradable Hydraulic Fluid-Mobil EAL
EnviroSyn 46H
Important: Mobil EAL EnviroSyn 46H is the only
synthetic biodegradable fluid approved by Toro. This
fluid is compatible with the elastomers used in Toro
hydraulic systems and is suitable for a wide-range
of temperature conditions. This fluid is compatible
with conventional mineral oils, but for maximum
biodegradability and performance the hydraulic system
should be thoroughly flushed of conventional fluid. The
oil is available in 19 liters (5 gallon) containers or 55
gallon drums from your Mobil Distributor.
Important: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive
for the hydraulic system oil is available in 20 ml (2/3
oz.) bottles. One bottle is sufficient for 15-22 liters (4-6
gallons) of hydraulic oil. Order part no. 44-2500 from
your authorized Toro distributor.
1. Position machine on a level surface, lower the cutting
decks and stop the engine.
2. Clean area around filler neck and cap of hydraulic tank
(Figure 17).
1. Hydraulic tank cap
3. Remove cap/dipstick from filler neck and wipe it with
a clean rag. Insert dipstick into filler neck; then remove
it and check level of fluid. Fluid level should be within
operating range on dipstick. Do not overfill.
4. If level is low, add appropriate fluid to raise level to
full mark.
5. Install cap/dipstick onto filler neck.

Check the Torque of the Wheel
Nuts
Torque the wheel nuts to Torque the wheel lug nuts to 94 to
122 N-m (70 to 90 ft-lb) after 1-4 hours of operation and
again after 10 hours of operation. Torque every 250 hours
thereafter.
WARNING
Failure to maintain proper torque of the wheel nuts
could result in personal injury.
Bleeding the Fuel System
You must bleed the fuel system before starting the engine if
any of the following situations have occurred:
•
Initial start up of a new machine.
•
Engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon fuel system
components; i.e., filter replaced, separator serviced, etc.
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 6 to 13 mm
(1/4 to 1/2 inch) 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.
1. Park the machine on a level surface and ensure that the
fuel tank is at least half full.
2. Open the hood.
3. Open the air bleed screw on the fuel injection pump
(Figure 18) with a 12 mm wrench.
