CHANGING THE HYDRAULIC
SYSTEM OIL AND FILTER
Normally, change the hydraulic oil and filter after
every 500 operating hours. If the oil becomes conta-
minated, contact your local TORO distributor
because the system must be flushed. Contaminated
oil looks milky or black when compared to clean oil.
1.
Park the machine on a level surface and turn the
engine off.
2.
Remove the screws securing the side panels
from the right and left sides of machine and
remove the panels.
Note: Place a funnel or trough under the drain
plug, to direct oil into the drain pan and prevent
hydraulic oil from running onto the machine
components.
3.
Remove the drain plug from reservoir and let
hydraulic oil flow into the drain pan. Reinstall
and tighten the plug when hydraulic oil stops
draining.
4.
Clean area around the filter mounting area.
Place the drain pan under the filter and remove
the filter.
5.
Lubricate the sealing gasket on the replacement
filter with Mobil DTE 26 hydraulic fluid, and
hand turn it until gasket contacts the filter head.
Then tighten
3
⁄
4
turn further. The filter should
now be sealed.
6.
Fill the hydraulic tank with hydraulic oil until
the level is up to the top of cone point on the
tank screen. DO NOT OVERFILL. Refer to
Check the Hydraulic System.
7.
Run the engine until the lift cylinder extends and
retracts and forward and reverse wheel motion is
achieved.
8.
Stop the engine and check the oil level in the
reservoir; add oil if necessary.
9.
Check all connections for leaks.
10. Dispose of oil properly.
CHECKING HYDRAULIC LINES
AND HOSES
After every 100 operating hours, check hydraulic
lines and hoses for leaks, kinked lines, loose mount-
ing supports, wear, loose fittings, weather deteriora-
tion and chemical deterioration. Make all necessary
repairs before operating.
