available, you may use another

Universal Tractor

Hydraulic Fluid (UTHF

), but they must be only

conventional, petrolium-based

products. The

specifications must fall within the listed range for
all of the following material properties and the fluid
should meet the listed industry standards. Check
with your oil supplier to determine if 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 recommendations.

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
l) of hydraulic oil. Order part no. 44-2500 from your
Authorized Toro Dealer.

7. Place a drain pan capable of hold 10 US Gallons

(37.8 l) under the hydraulic tank.

8. Pinch the hose clamp and slide the clamp and hose

off of the fitting on the hydraulic tank, allowing the
hydraulic fluid to drain from the hose and tank into
the pan.
