Toro 41568 Operator's Manual page 30

Check the engine coolant as directed by the manufacturer
every 400 operating hours and change it as needed. Use 12
qt (11.5 l) of a solution of 50% water and 50% permanent
ethylene glycol antifreeze.
1. Position the sprayer on a level surface, set the parking
brake, stop the pump, stop the engine, and remove the
ignition key.
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.
2. When the engine is cool, remove the radiator cap
(Fig. 37).

6. Slowly add a solution of 50% water and 50%
permanent ethylene glycol antifreeze until the coolant is
3/4 to 1-1/2 inches (2 to 4 cm) below the bottom of the
filler neck.
7. Install and secure the radiator cap.
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 your local Toro
distributor because the system must be flushed.
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
Use of any other filter may void the
warranty on some components.
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. 39).
