Servicing The Hydraulic Oil - Toro 41581 Operator's Manual

5. Close the drain.
6. Remove the radiator cap.
7. Slowly fill the radiator with coolant to approximately
1 inch (2.5 cm) below the sealing surface of the cap.
Note: This will allow for the coolant to expand without
it overflowing while the engine is warming up.
8. Use enough coolant to fill the engine and the system
lines.
9. Start the engine with the cap loosely on the radiator.
10. Allow the engine to warm up until the thermostat opens.
Note: This usually occurs between 175° and 190° F.
Caution
As the engine continues to run, the coolant will
become hot and pressurized. If you open the
radiator cap when the coolant is hot, it could spray
out and severely burn you or bystanders.
Wear protective clothing and avoid contact with
hot coolant as you open the radiator cap.
11. Once the coolant has warmed up, top off the coolant
level to the sealing surface of the cap and tighten the
cap.
12. Open the recovery bottle cap and fill with coolant to the
Cold position after you tighten the radiator cap.
13. Check the coolant levels after several shut down and
start up cycles and top off the coolant as needed.
Caution
If the engine has been running, the coolant may be
hot and pressurized. If you open the radiator cap
when the coolant is hot, it could spray out and
severely burn you or bystanders.
Allow the engine to cool for at least 15 minutes
before opening the radiator cap. The radiator cap
must be cool to the touch.

Servicing the Hydraulic Oil

Replace the hydraulic oil filter after the first 8 operating
hours and replace the hydraulic oil and filter every 400
hours thereafter.
If the oil becomes contaminated, contact an Authorized
Toro Distributor to have the system flushed.
Note: Contaminated oil looks milky or black when
compared to clean oil.
Replacing the Hydraulic Oil Filter
Use the Toro replacement filter (Part No. 86-3010).
Important Using any other filter may void the
warranty on some components.
Warning
Hot hydraulic fluid can cause severe burns.
Allow the hydraulic oil to cool before performing
any maintenance to the hydraulic system.
1. Position the sprayer on a level surface, set the parking
brake, stop the pump, stop the engine, and remove the
ignition key.
2. Clean the area around the filter mounting area (Fig. 42).
1. Hydraulic filter
3. Place a drain pan under the filter.
4. Remove the filter (Fig. 42).
5. Lubricate the new filter gasket (Fig. 42).
6. Ensure that the filter mounting area is clean.
7. Screw the new filter on until the gasket contacts the
mounting plate, then tighten the filter 1/2 turn.
8. Start the engine and let it run for about 2 minutes to
purge air from the system.
9. Stop the engine, check the hydraulic oil level, and check
for leaks.
10. Dispose of the used filter at a certified recycling center.
