Checking The Hydraulic Fluid Level; Checking The Tire Pressure; Starting And Stopping The Engine - Toro 03781 Operator's Manual

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 37). Remove the cap from the
filler neck.

1. Hydraulic tank cap
3. Remove the dipstick from the filler neck and wipe it
with a clean rag. Insert the dipstick into the filler neck;
then remove it and check the fluid level. The fluid level
should be between the two marks on the dipstick.
4. If the level is low, add the appropriate fluid to raise the
level to the upper mark.
5. Install the dipstick and cap onto the filler neck.

Checking the Tire Pressure

Service Interval: Before each use or daily
The tires are over-inflated for shipping. Therefore, release
some of the air to reduce the pressure. The correct air
pressure in the tires is 83-103 kPa (12–15 psi). Check the
tire pressure daily.
Important: Maintain the recommended pressure in all
tires to ensure a good quality-of-cut and proper machine
performance. Do not under-inflate.
Starting and Stopping the
Engine
Starting the Engine
Important: The fuel system must be bled if any of the
following situations have occurred:
•
The engine has ceased running due to lack of fuel.
•
Maintenance has been performed upon the fuel system
components.
