Cleaning the Cylinder Head
Fins
To avoid overheating and possible engine damage, the
cooling fins on the cylinder head must be kept clean.
Changing the Hydraulic
System Oil and Filter
The hydraulic system filter must be changed initially, after
the first 8 hours of operation, and thereafter every 400
hours of operation or yearly, whichever occurs first. Use a
genuine Toro oil filter for replacement. The hydraulic oil
must be changed every 400 hours of operation or yearly,
whichever occurs first.
1. Park the machine on a level surface and turn the engine
off.
2. Pivot the seat upward.
3. Disconnect the tube from the bottom fitting of the
reservoir and let the oil flow into a drain pan. Install and
tighten the tube when the oil stops draining.
4. Clean the area around the hydraulic oil filter (Fig. 20).
Remove the filter from the bottom of the filter housing
and allow the oil to flow into a drain pan. Use a
bottom-type filter wrench. Dispose of the oil filter
properly.

5. Apply a film of oil on the filter gasket. Install the filter
by hand until the gasket contacts the mounting head;
then tighten the filter an additional 3/4 turn.
6. Fill the reservoir to the proper level; refer to Checking
the Hydraulic System.
7. Place all of the controls in the neutral or disengaged
position and start the engine. Run the engine at the
lowest possible RPM to purge the system of air.
8. Run the engine until the lift cylinder extends and
retracts and forward and reverse wheel motion is
achieved.
9. Stop the engine and check the oil level in the reservoir.
Add oil if necessary.
10. Check all connections for leaks.
11. Lower the seat.
12. Dispose of used oil properly.
Checking the Hydraulic Lines
and Hoses
Check the hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings, weather
deterioration, and chemical deterioration. Make all
necessary repairs before operating.
Warning
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
• Keep your body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Seek immediate medical attention if fluid is
injected into skin.
Charging the Hydraulic System
Whenever a hydraulic component is repaired or replaced,
the hydraulic oil filter should be changed and the hydraulic
system charged.
Important
Make sure that the hydraulic reservoir and
filter are filled with oil at all times when charging the
hydraulic system.
1. Park the machine on a level surface and turn the engine
off.
2. Pivot the seat upward and remove the engine shield.
3. Loosen the locknut on the spring adjusting pin until the
bearing moves freely from the cam on the lever
(Fig. 21), allowing the pump shaft freedom to rotate
during start-up.
