HYDRAULIC MAINTENANCE
CAUTION
Before servicing or making adjustments to the
machine, stop engine and remove key from the
switch.
CHANGING HYDRAULIC OIL (Fig. 35 & 36)
Change hydraulic oil filter initially after the first 50 hours
of operation, thereafter change hydraulic oil and filter
after every 800 operating hours. If oil becomes
contaminated, contact your local TORO distributor
because the system must be flushed. Contaminated oil
looks milky or black when compared to clean oil.
1. Turn engine off, release hood latch and raise hood.
2. Remove drain plug from rear of reservoir and
hydraulic line from front of reservoir (Fig. 35) and let
hydraulic oil flow into drain pan. Reinstall and tighten
plug and line when hydraulic oil stops draining.
3. Fill reservoir with approximately 6.5 gallons of
hydraulic oil. Refer to Check Hydraulic Circuit Oil.
IMPORTANT: Use only hydraulic oils specified.
Other fluids could cause system damage.

4. Install reservoir cap, lower hood and latch. Start
engine and use all hydraulic controls to distribute
hydraulic oil throughout the system. Also check for
leaks. Then stop the engine.
5. With wing decks raised, center deck down and oil
warm, look into sight gauge (Fig. 36). If hydraulic oil is
not visible, add enough oil to raise level to middle
(maximum) of sight gauge. To prevent over filling, do
not fill if oil is cold. DO NOT OVER FILL.

REPLACING HYDRAULIC FILTER (Fig. 37)
Initially, change filter after the first 50 operating hours,
thereafter, every 800 operating hours or annually,
whichever comes first.
Only the Toro replacement filter (Part No.86-3010) can
be used in the hydraulic system.
IMPORTANT: Use of any other filter may void the
warranty on some components.
1. Turn engine off, release hood latch and raise hood.
2. Clean area around filter mounting area (Fig. 37).
Place drain pan under filter and remove filter.

3. Lubricate new filter gasket and fill the filter with
hydraulic oil.
4. Assure filter mounting area is clean. Screw filter on
until gasket contacts mounting plate. Then tighten filter
one-half turn.
5. Start engine and let run for about two minutes to
purge air from the system. Stop the engine and check
oil level. Also check for any leaks.
