Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline 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 gasoline to
expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.

Servicing the Hydraulic System

Recommended Hydraulic Fluid
The machine's reservoir is filled at the factory with
approximately 8.5 gallons (32.2 liters) of high quality
hydraulic fluid. Check the level of hydraulic fluid before
the engine is first started and daily thereafter. The
appropriate hydraulic oils are listed below.
The following list is not assumed to be all-inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to the
products listed. Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.

Climate 325F (05C) to 1105F (435C)
Mobil
Amoco
Chevron
Conoco
Exxon
Pennzoil
Shell
Texaco
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.

Biodegradable Hydraulic Fluid—Mobil 224H
Important
Mobil EAL 224H is the only biodegradable
oil tested and approved by Toro. Contamination by
mineral–based hydraulic fluids will change the
biodegradability and toxicity of this oil. When changing
from standard fluid to the biodegradable type, be certain to
follow the approved flushing procedure published by
