Checking The Hydraulic Fluid - Toro 03673 Reelmaster 5410-G Operator's Manual

1. Fuel tank cap
4. Add unleaded regular gasoline to the fuel tank until the
level is 25 mm (1 inch) below the bottom of the filler
neck.
This space in the tank allows gasoline to expand. Do
not fill the fuel tank completely full.
5. Install the fuel tank cap securely. Wipe up any gasoline
that may have spilled.

Checking the Hydraulic Fluid

The machines reservoir is filled at the factory with
approximately 30 liters (8 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 19 liter (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.
High Viscosity Index/Low Pour Point Anti-wear Hydraulic
Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM
D2270
Pour Point, ASTM D97
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, 18° C (65° F) to 49° C
(120° F), 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 liter (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. This red dye is not
recommended for use with biodegradable fluids. Use
food coloring.
1. Position machine on a level surface, lower the cutting
units and stop the engine.
2. Clean area around filler neck and cap of hydraulic tank
(Figure 29). Remove cap from filler neck.
1. Hydraulic tank cap
3. Remove 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 6.3 mm
(1/4 inch) of mark on dipstick. Do not overfill.
4. If level is low, add appropriate fluid to raise level to
full mark.
5. Install dipstick and cap onto filler neck.
