operation. Replace belt as required.
1.
Proper tension will allow 0.64 cm deflection on the belt mid-
way between the pulleys, when pressed firmly with thumb.
2.
If deflection exceeds 0.64, loosen the alternator mounting
bolts. Adjust the alternator belt's tension by adjusting the ten-
sion screw. Check the deflection of belt again to assure its ten-
sion is correct.
CHANGING HYDRAULIC FLUID (Fig. 42)
Change 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
the oil.
1.
Turn the engine off and raise the hood.
2.
Remove the drain plug from bottom of the reservoir and let
hydraulic fluid flow into the drain pan. Reinstall and tighten
the plug when hydraulic fluid stops draining.
3.
Fill the reservoir with approximately 32 l of hydraulic fluid.
Refer to Checking Hydraulic Fluid.
IMPORTANT: Use only hydraulic fluids specified. Other
fluids could cause system damage.
4.
Install the reservoir cap. Start the engine and use all hydraulic
controls to distribute hydraulic fluid throughout the system.
Also check for leaks. Then stop the engine.
5.
Check the level of fluid and add enough to raise the level to
the FULL mark on the dipstick. DO NOT OVER FILL.
REPLACING THE HYDRAULIC FILTER
(Fig. 43)
The hydraulic system filter head is equipped with a service interval
indicator. With the engine running, view the indicator. It should be
in the GREEN zone. When the indicator is in the RED zone, the fil-
ter element should be changed.
Use the Toro replacement filter (Part No. 94-2621).
IMPORTANT: Use of any other filter may void the warranty on
