Screw the filter on until the gasket contacts the
mounting plate; then tighten the filter 1/2 turn.

to purge air from the system. Shut off the engine
and check for leaks.
Changing the Hydraulic
Fluid
Service Interval: Every 400 hours
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. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key from the ignition
switch.
2. Disconnect the large hydraulic hose ( Figure 66 )
from the reservoir and let the hydraulic fluid flow
into a drain pan.
