Checking The Hydraulic System - Toro Reelmaster 2000-D 03431 Operator's Manual

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. Carefully remove the radiator cap (Fig. 23).

2. Check the coolant level in the radiator. The radiator
should be filled to the middle of the horizontal filler
neck and the surge tank (Fig. 24) should be half way
between Full and Low.

3. If the coolant level is low, replenish the system. Do not
overfill.
4. Install the radiator cap.

Checking the Hydraulic System

The machines reservoir is filled at the factory with
approximately 3.3 gallons (12.5 l) 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:
Toro Premium All Season Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or 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. We do not
recommend the use of synthetic fluid. Consult with your
lubricant distributor to identify a satisfactory product Note:

High Viscosity Index/Low Pour Point Antiwear
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
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no.44–2500 from your authorized Toro distributor.

Biodegradable Hydraulic Fluid – Mobil 224H
Toro Biodegradable Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluid: Mobil EAL 224H
This is vegetable–oil based biodegradable oil tested and
approved by Toro for this model. This fluid is not as
resistant to to high temperatures as standard fluid, so install
an oil cooler if required by the operator manual and follow
recommended fluid change intervals with this fluid.
Contamination by mineral–based hydraulic fluids will
change the biodegradability and toxicity of this oil. When
changing from standard fluid to the biodegradable type, be
certain to follow the approved flushing procedure. Contact
your local Toro Distributor for details.
