IMPORTANT:
Use only hydraulic oils specified.
Other fluids could cause system damage.
Note:
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 (15-23 l) of hydraulic oil. Order
Part No. 44-2500 from your Authorized Toro
Distributor.
Check Oil Level
1.
Visually check hydraulic oil level daily through
sight glass (Fig. 46). With machine on a level surface,
oil should be in the middle of the sight glass when
warm and slightly below level when cold.
2.
If oil needs to be added, clean area thoroughly
around the fill cap before removing cap (Fig. 46). Add
oil until proper level is indicated in sight glass.

Replace Hydraulic Filter (Initial)
After 50 hours initial operation, replace the hydraulic
filter (Toro Part No. 69-1720).
1.
Place drain pan under filter and remove filter
(Fig. 47).

1. Hydraulic Oil Filter
2.
Coat O-ring of the replacement filter with clean
hydraulic oil before installing.
3.
To tighten filter, hand turn filter element onto filter
head until element is firmly seated against the head.
4.
Start engine and check for leaks. Check oil level
after engine has been stopped. Add oil, if necessary.
Inspect Lines and Fittings
Every 100 hours operation inspect all hoses, lines and
fittings for signs of leakage or damage (blisters, cut
hoses, etc.)
CAUTION: Replace any suspect hoses or lines
immediately to prevent machine damage or
personal injury.
CAUTION
Keep body and hands away from pin hole
leaks or nozzles that eject hydraulic fluid
under high pressure. Use paper or card
board, not hands, to search for leaks.
Hydraulic fluid escaping under pressure
can have sufficient force to penetrate skin
and do serious damage. If fluid is injected
into the skin it must be surgically removed
within a few hours by a doctor familiar with
this form of injury or gangrene may result.
Replace Hydraulic Filter
Every 500 hours operation, replace the filter element;
refer to Replace Hydraulic Filter.
Drain Water From Hydraulic Reservoir
Every 500 hours operation, drain water from reservoir
at three (3) locations.
1.
Place drain pan under reservoir.
2.
Locate plugs at right rear behind front wheel, at
rear center and front center of reservoir (Fig. 48).
