Subject: Recommendations and Specifications for use of Biodegradable Fluids.

This bulletin is a historic reference to identify the units that can be converted to use Toro

Biodegradable All-Season Hydraulic Fluid. Only those Model Numbers listed in this bulletin

can be converted. Alternative hydraulic fluid specifications that can be used in units after

the serial number range listed in this bulletin will be stated in the Operator’s Manual for each

unit.

Toro Biodegradable All-Season Hydraulic Fluid is currently available in 5-gallon (100-7674)

or 55 gallon (108-1189) containers through your local Toro Commercial Products

Distributor. Before deciding to convert a unit you will need to understand the following

cautions and procedures. Additional information is provided in the Hydraulic System Fluid

Recommendations included with this bulletin.

1) Make certain your unit is listed in this bulletin or your Operator’s Manual specifies your

machine is compatible with this fluid.

2) Consider the effects of outside influences such as high ambient temperatures and high

moisture environments. More frequent fluid changes should be anticipated.

3) Toro Biodegradable All-Season Hydraulic Fluid is the only qualified biodegradable type

fluid approved for use in the TORO products listed. A fluid that does not perform to the

same level may jeopardize the long term performance of hydraulic components.

4) *IMPORTANT:

Do not use biodegradable fluids when the differential housing is the

system reservoir (e.g. Reelmaster

5000 Series traction system-units with * in product list

above, Groundsmaster

200/300 Series). These fluids do not contain the necessary

lubrication properties for a ring gear and pinion application (see your Operator’s Manual).

5) If using Toro Biodegradable All-Season Hydraulic Fluid in the Greensmaster

3200/3250,

an auxiliary oil cooler must be installed to maintain acceptable system temperatures.

6) Converting a unit to use Toro Biodegradable All-Season Hydraulic Fluid requires the

removal of as much of the original fluid as possible. Mixtures of non-compatible fluids

in significant amounts may have adverse effects (e.g. chemical reactions). Flushing

procedures and a Product Data Sheet are included with this bulletin.

The type of fluid selected is based on a variety of factors, such as: 1) 2) 3) 4) Hydraulic component manufacturers recommendations Toro testing and experience The availability of the fluid type throughout the world Product application demands The system fluids most commonly used in hydraulic-driven equipment are petroleum-based products.

Important: For a fluid to perform well and avoid undesirable side effects it is also extremely important that it contains no more than the maximum water content identified in the specifications above when the fluid is put into the system. Before first introducing biodegradable fluid into a product, the system must be flushed of the original fluid to prevent fluid contamination as described in the technical information from Mobil Corporation included with this bulletin.
