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 fluids, but
for maximum biodegradability and performance,
the hydraulic system should be thoroughly
flushed of conventional fluid. The fluid is available
in 19 L (5 US gallons) containers or 208 L (55 US
gallons) 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 fluid is available in
20 ml (0.67 fl oz) bottles. One bottle is sufficient
for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid.
Order Part No. 44-2500 from your authorized Toro
distributor. This red dye is not recommended for
use with biodegradable fluids.
Checking the Hydraulic-Fluid
Level
The hydraulic-fluid reservoir is filled at the factory
with high quality hydraulic fluid. Before operating the
machine each day, check the level of the hydraulic
fluid. Your machine has a dipstick or a white plastic
window on the front of the hydraulic-fluid reservoir
(behind the seat on the left side of the machine) that
is used to check the hydraulic-fluid level. The fluid
should be between the window lines or the dipstick
marks; if not, add more appropriate fluid.
Refer to Figure 47 for this procedure.
cSt @ 40°C 44 to 50
cSt @ 100°C 7.9 to 8.5
140 to 160
-34°F to -49°F
1. Hydraulic-tank cap or dipstick location
1. Position the machine on a level surface.
Note:
Ensure that the machine has cooled
down so that the fluid is cold.
2. Check the fluid level according to the tank on
your machine:
•
If your tank has a sight window, check the oil
level there and proceed to step 5.
•
If your tank does not have a sight window,
locate the dipstick on the top of the hydraulic
tank and proceed to step 3.
3. Remove the dipstick and wipe it with a clean
rag, then screw the dipstick back into the tank.
4. Remove the dipstick and check the fluid level. If
the fluid is between the marks on the dipstick,
the level is sufficient. If the level is not between
the marks, more fluid is needed.
5. Remove the cap or dipstick (depending on your
machine) from the hydraulic fluid tank and slowly
fill the tank with the appropriate high-quality
hydraulic fluid until the level is between the 2
lines on the sight window or 2 marks on the
dipstick.
6. Install the cap or dipstick and wipe up any fluid
that may have spilled.
Important:
Check the level of the hydraulic
fluid before the engine is first started and
daily thereafter.
