The proper hydraulic fluids must be specified for
mobile machinery (as opposed to industrial plant usage),
multiweight-type, with ZnDTP or ZDDP antiwear additive
package (not an ashless-type fluid).
Important:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system oil is available in 20 ml (2/3 fl oz)
bottles. One bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order part 44-2500 from your
Authorized Toro Distributor.
Synthetic, Biodegradable Hydraulic Fluid: Available in
19 L (5 US gallon) containers or 208 L (55 US gallon)
drums—see the
Parts Catalog or your Toro distributor
for part numbers.
This high-quality, synthetic, biodegradable fluid has been
tested and found compatible for this Toro model. Other
brands of synthetic fluid may have seal compatibility problems
and Toro cannot assume responsibility for unauthorized
substitutions.
Note:
This synthetic fluid is not compatible with the
Toro Biodegradable Fluid previously sold. See your Toro
Distributor for more information.

1.
Position the machine on a level surface, lower the
cutting units, and shut off the engine.
2.
Check the sight-level gauge on the side of the tank.
Note:
The level needs to be at the upper mark.
3.
If additional hydraulic fluid is needed, clean the area
around the filler neck and the cap of the hydraulic tank
(
) and remove the cap.

Checking the Tire Pressure
Check the air pressure in the front and rear tires. Refer to the
chart below for the correct pressure.
Important:
Maintain correct tire pressure in all tires to
ensure correct contact with the turf.
Recommended tire pressure is 1 bar (14.5 psi) for general all
around use. Tire pressures can be adjusted according to the
following table depending on operating conditions.

Service Interval:
Before each use or daily
Torque the wheel-lug nuts to 200 N∙m (148 ft-lb) for the front
axle, and 54 N∙m (40 ft-lb) for the rear axle.
