Maintenance
Changing the Hydraulic Fluid
Service Interval:
Every 800 hours
Change the hydraulic fluid after every 800 operating hours,
in normal conditions. If the fluid becomes contaminated,
contact your local Toro distributor because the system must
be flushed. Contaminated fluid looks milky or black when
compared to clean oil.
1.
Turn the engine off and raise the hood.
2.
Remove the drain plug on the bottom front of the
reservoir and let the hydraulic fluid flow into large drain
pan. Install an tighten the plug when the hydraulic fluid
stops draining.
3.
Fill the reservoir (
) with hydraulic fluid; refer
to Checking the Hydraulic Fluid.
Important:
Use only the hydraulic fluids
specified. Other fluids could cause system
damage.
