Hydraulic Fluid Specification; Checking The Hydraulic-Fluid Level - Toro GreensPro 1260 Operator's Manual

Hydraulic Fluid
Specification
Recommended Hydraulic Fluid: Toro Premium All
Season Hydraulic Fluid (Available in 5 US gallon
pails or 55 US gallon drums. Refer to the Parts
Catalog or contact your authorized Toro distributor for
part numbers.
Alternative fluids: If the Toro fluid is not available,
other conventional, petroleum-based fluids may be
used, provided they meet all the following material
properties and industry specifications. Check with
your oil supplier to see whether the oil meets these
specifications.
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 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).
Note:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system fluid is available in 20 ml (2/3 fl
oz) bottles. One bottle is enough for 15 to 22 L (4 to 6
US gallons) of hydraulic fluid. Order Part No. 44-2500
from your authorized Toro distributor.

Checking the
Hydraulic-Fluid Level
Service Interval: Before each use or daily Check the
level of the hydraulic fluid before
the engine is first started and daily
thereafter.
Note:
Before working on any part of the hydraulic
drive system, shut off the engine to depressurize the
system. Before starting the engine after hydraulic
system maintenance, and pressurizing the hydraulic
lines, check all hoses and connectors for damage and
to ensure that they are tight. Replace any damaged
hoses and tighten any loose couplings as required.
1. Prepare the machine for maintenance; refer to
Preparing for Maintenance (page
2. Raise the operator's seat; refer to
Operator's Seat (page
3. Remove the cap and check hydraulic-fluid level
in the reservoir
The hydraulic-fluid level should cover the word
C that is embossed into the baffle of the
OLD
reservoir.
4. If necessary, add the specified hydraulic fluid to
the reservoir until the fluid covers the cold-fluid
level on the baffle.
Note:
The baffle in the reservoir is labeled H
and C . Fill the reservoir to the appropriate
OLD
level depending upon the temperature of the
fluid. The fluid level varies with the temperature
of the fluid. The cold level shows the level of
the fluid when it is at 24°C (75°F). The hot level
shows the level of fluid when it is at 107°C
(225°F).
