Checking The Hydraulic-Fluid Level; Changing The Hydraulic Fluid - Toro Reelmaster 5410 Operator's Manual

Checking the
Hydraulic-Fluid Level
Service Interval: Before each use or daily
The reservoir is filled at the factory with 56.7 L (15 US
gallons) of high-quality hydraulic fluid. The best time
to check the hydraulic oil is when the fluid is cold. The
machine should be in its transport configuration. The
recommended replacement fluid is:
Toro Premium All Season Hydraulic Fluid (Available in
19 L (5 US gallon) pails or 208 L (55 US gallon) drums. See
the Parts Catalog or your Toro Distributor for part numbers.)
Alternative fluids: If the Toro fluid is not available,
other conventional, petroleum-based fluids may be
used, provided that they meet all of the following
material properties and industry specifications. Check
with your oil supplier to see whether the oil meets
these specifications.
Note:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
only products from reputable manufacturers who
stand behind their recommendation.
High Viscosity Index/Low Pour Point Antiwear Hydraulic
Fluid, ISO VG 46 Multigrade
Material Properties:
Viscosity, ASTM D445
Viscosity index, ASTM
D2270
Pour point, ASTM D97
FZG, fail stage
Water content (new fluid)
Industry Specifications:
Vickers I-286-S, Vickers M-2950-S, Denison HF-0,
Vickers 35 VQ 25 (Eaton ATS373-C)
The proper hydraulic fluids must be specified for
mobile machinery (as opposed to industrial plant
usage), multiweight-type, with ZnDTP or ZDDP
anti-wear additive package (not an ashless-type fluid).
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. 1 bottle is
sufficient for 15 to 22 L (4 to 6 US gallons) of
hydraulic oil. Order Part Number 44-2500 from
your Toro Distributor.
Synthetic, Biodegradable Hydraulic Fluid (Available in
19 L (5 US gallon) pails or 208 L (55 US gallon) drums. See
the Parts Catalog or your Toro Distributor for part numbers.)

This synthetic fluid is not compatible with the
Toro Biodegradable Fluid previously sold. See your
Toro Distributor for more information.
1. Position the machine on a level surface, lower
the cutting units, and stop the engine.
2. Clean the area around the filler neck and the
cap of the hydraulic tank
1. Hydraulic-tank cap
3. Remove the cap/dipstick from the filler neck and
wipe it with a clean rag.
4. Insert the dipstick into the filler neck; then
remove it and check the level of fluid.
Note:
The fluid level should be within operating
range on the dipstick.
Important:
Do not overfill the tank.
5. If the level is low, add the appropriate amount of
fluid to raise the level to the full mark.
6. Install the cap/dipstick onto the filler neck.
Changing the Hydraulic
Fluid
Service Interval: Every 800 hours
Every 2 years—Drain and flush the hydraulic
tank.
If the fluid becomes contaminated, contact your Toro
Distributor because the system must be flushed.
Contaminated fluid looks milky or black when
compared to clean oil.
1. Stop the engine and raise the hood.
