Changing The Hydraulic Filter - Toro Groundsmaster 3500-D Operator's Manual

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, 65° F
(18° C) to 120° F (49° C), 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 L (5
US gallons) 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 to 22 L (4 to 6 US gallons) of
hydraulic oil. Order Part No. 44-2500 from your
authorized Toro distributor.
Use the following procedure to check the hydraulic
fluid:
1. Perform the pre-maintenance procedure; refer
to Preparing the Machine for Maintenance (page
36).
2. Clean the area around the filler neck and
hydraulic-tank cap
cSt @ 40° C 44 to 48
cSt @ 100° C 7.9 to 8.5
140 to 160
-34° F to -49° F
(Figure 64).
1. Hydraulic-tank cap
3. Remove the hydraulic-tank cap
4. Remove the dipstick from the filler neck and
wipe it with a clean rag.
5. Insert the dipstick into the filler neck, then
remove it and check the fluid level.
Note:
The fluid level should be within 6 mm
(1/4 inch) of the mark on the dipstick.
6. If the level is low, add the appropriate fluid to
raise the level to the F
7. Install the dipstick and cap onto the filler neck.
Changing the Hydraulic
Filter
Service Interval: After the first 10 hours
Every 200 hours/Yearly (whichever comes first)
Use a genuine Toro replacement filter, Part No.

Using any other filter may void the
warranty on some components.
1. Perform the pre-maintenance procedure; refer
to Preparing the Machine for Maintenance (page
36).
2. Pinch off the hose to the filter-mounting plate.
3. Clean around the filter-mounting area, place a
drain pan under the filter, and remove the filter
