Before Operating
If you leave the key in the ignition switch, someone
could accidently start the engine and seriously
injure you or other bystanders.
Remove the key from the ignition before you do
any maintenance.
Caution
Check Hydraulic Fluid
The machine’s reservoir is filled at the factory with
approximately 10 gallons of high quality hydraulic fluid.
Check the level of hydraulic fluid before the engine is
first started and daily thereafter. Appropriate hydraulic
oils are listed below.
The following list is not assumed to be all–inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to the
products listed. Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.

Important
The ISO VG 46 Multigrade fluid has been
found to offer optimal performance in a wide range of
temperature conditions. For operation in consistently high
ambient temperatures, 65
F (18
C) to 120
F (49
C),
ISO VG 68 hydraulic fluid may offer improved
performance.
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. Not recommended for biodegradable fluid (use
food coloring).
1. Park machine on a level surface and stop engine. Make
sure machine has been operated so oil is warm. Check
level of oil by viewing sight gauge. If oil is up to
middle of gauge, oil level is sufficient.

2. If oil level is lower than middle of gauge, remove cap
from hydraulic oil reservoir and slowly add a high
quality hydraulic oil until level reaches middle
(maximum) of sight gauge. DO NOT OVER FILL.
Important
To prevent system contamination, clean top
of hydraulic oil containers before puncturing. Assure pour
spout and funnel are clean.
3. Install reservoir cap.
Check Tire Pressure
Correct air pressure in the tires is 18 psi.
IMPORTANT:
Maintain even pressure in both tires to
assure proper machine performance. DO NOT UNDER
INFLATE.
Check Torque Of Wheel Nuts
Failure to maintain proper torque of the wheel
nuts could result in failure or loss of wheel and
may result in personal injury.
Torque the wheel nuts to 85–100 ft.-lb.
(115–136 N
m) after 1–4 hours of operation and
again after 10 hours of operation. Torque every
200 hours thereafter.
