Group 2 fluids are recommended for heavy-duty use in hot
climates where ambient temperatures range from about
65
°
F (18
°
C) to 120
°
F (49
°
C). Use at lower ambient
temperatures may result in hard starting, increased engine
laboring while cold, sluggish or non-operating spool valves
while cold and high filter back-pressure due to the higher
viscosity of these fluids.
Note:
When changing from one type of hydraulic fluid to
another, be certain to remove all the old fluid from the
system, as some fluids are incompatible with others.
Group 3 Hydraulic Fluid (Biodegradable)
ISO VG 32/46 anti-wear hydraulic fluid
Mobil
EAL 224H
Note:
This biodegradable hydraulic fluid is not compatible
with the fluids in group 1 or 2.
Note:
This oil is available in 5 gallon (19 l) containers from
your Authorized Toro Distributor. Order Part No.
100-7674.
Note:
When changing from standard fluid to the
biodegradable type, be certain to follow approved flushing
procedures as published by Mobil. Contact your local Toro
Distributor for details.
Checking the Hydraulic System
Check the level of hydraulic fluid before the engine is
first started and daily thereafter.
1.
Position the machine on a level surface. Make sure the
machine has cooled down so the oil is cold.
2.
Remove the cap from the top of the reservoir and check
the fluid level. The fluid should be approximately
3-1/2 in. (89 mm) below the top of the fill hole
(Fig. 15).

3.
If the oil level is low, slowly fill the reservoir with ISO
VG 46/48 or equivalent hydraulic oil until the level is
up to the correct level. Do not mix oils.
4.
Install the cap.
Important
To prevent system contamination, clean the
top of the hydraulic oil containers before puncturing them.
Ensure that the pour spout and funnel are clean.
Note:
Make a close visual inspection of the hydraulic
components. Inspect them for
Ieaks,
loose fasteners,
missing parts, improperly routed lines, etc. Make any
corrections necessary.
Tire Pressure
The tires are over-inflated at the factory for shipping
purposes. Reduce the pressure to the proper levels before
starting the unit.
Vary the tire pressure for the front wheels, depending upon
your turf conditions, from a minimum of 8 psi to a
maximum of 12 psi (55 to 83 kPa).
Vary the tire pressure for the rear wheel from a minimum of
8 psi to a maximum of 15 psi (55 to 103 kPa).
Checking the Torque of the
Wheel Nuts
Failure to maintain proper torque of the wheel
nuts could result in personal injury.
Torque the wheel nuts to 70–90 ft.-lb. after
1–4 hours of operation and again after 10 hours of
operation. Torque every 200 hours thereafter.
