Checking The Cooling System; Checking The Hydraulic Fluid - Toro Reelmaster 5510-D Operator's Manual

Checking the Cooling
System
Service Interval: Before each use or daily
Clean debris off the screen, oil cooler, and front of
the radiator daily and more often if conditions are
extremely dusty and dirty. Refer to
from the Cooling System (page
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the level of coolant in the expansion tank at the
beginning of each day before starting the engine. The
capacity of the cooling system is 6.6 L (7.0 US qt).
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and
cause burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Check the level of coolant in the expansion tank
(Figure 28).
The coolant level should be between the marks
on the side of the tank.

2. If the coolant level is low, remove the
expansion-tank cap and replenish the system.
Do not overfill.
3. Install the expansion-tank cap.

Checking the Hydraulic
Fluid
Service Interval: Before each use or daily
The machines reservoir is filled at the factory with
approximately 30 L (8 US 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 L (5 US gallon) pails or 208 L (55 US gallon) drums.
See the Parts Catalog or your authorized 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. Do
not use synthetic fluid. Consult with your lubricant
distributor to identify a satisfactory product.
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 Anti-wear Hydraulic
Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM D2270 140 to 160
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 L
(5 US gallon) containers or 208 L (55 US gallon)
drums from your Mobil distributor.
Important:
Many hydraulic fluids are almost
colorless, making it difficult to spot leaks. A
