Checking The Hydraulic Fluid Level - Toro 03780 Operator's Manual

DANGER
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the fuel vapors. A fire or explosion from
fuel can burn you and others and can damage
property.
• Always place fuel containers on the ground away
from your vehicle before filling.
• Do not fill fuel 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 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 fuel dispenser nozzle.
• If a fuel 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.
1. Park the machine on a level surface.
2. Using a clean rag, clean area around fuel tank cap.
3. Remove cap from the fuel tank (Figure 34).

4. Fill the tank until the level is to the bottom of the filler
neck with diesel fuel.
5. Install fuel tank cap tightly after filling tank.
Note: If possible, fill the fuel tank after each use. This
will minimize possible buildup of condensation inside
the fuel tank.
Checking the Hydraulic Fluid
Level
Service Interval: Before each use or daily
The machines reservoir is filled at the factory with
approximately 28.4 liters (7.5 U.S. gallons) of high quality
hydraulic fluid. Check the level of the hydraulic fluid
before the engine is first started and daily thereafter. The
recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
5 gallon pails or 55 gallon drums. See parts catalog or Toro
distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We do not
recommend the use of synthetic fluid. Consult with your
lubricant distributor to identify a satisfactory product Note:
Toro will not assume responsibility for damage caused by
improper substitutions, so use only products from reputable
manufacturers who will stand behind their recommendation.

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 liter (5 gallon) containers or 55 gallon
drums from your Mobil Distributor.
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 20 ml m (2/3 ounce) bottles. One
bottle is sufficient for 15-22 1iters (4-6 gallons) of hydraulic
oil. Order part no. 44-2500 from your authorized Toro
distributor.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, and remove the key.
2. Clean the area around the filler neck and cap of the
hydraulic tank (Figure 35). Remove the cap from the
filler neck.
