CLEANING THE CYLINDER HEAD
FINS
To avoid overheating and possible engine damage, the
cooling fins on the cylinder head must be kept clean.
CHANGING 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 comes first.
Use a genuine Toro oil filter for replacement. The
hydraulic oil must be changed every 400 hours of opera-
tion or yearly, whichever comes first.
1. Park the machine on a level surface and turn the
engine off.
2. Pivot seat upward.
3. Disconnect hose from bottom fitting of the reservoir
and let oil flow into drain pan. Reinstall and tighten
the hose when the oil stops draining.
4. Clean the area around the hydraulic oil filter.
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 mounting
head; then tighten filter an additional three-fourth's
turn.

6. Fill the reservoir to proper level, refer to Check the
Hydraulic System.
7. Place all controls in the neutral or disengaged posi-
tion and start the engine. Run the engine at its low-
est 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 reser-
voir, add oil if necessary.
10. Check all connections for leaks.
11. Lower the seat.
12. Dispose of oil properly.
CHECKING HYDRAULIC LINES
AND HOSES
Check 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.
Keep body and hands away from pin hole leaks or
nozzles that eject high-pressure hydraulic fluid.
Use cardboard or paper to find hydraulic leaks.
Hydraulic fluid escaping under pressure can pene-
trate skin and cause injury. Fluid accidentally
injected into the skin must be surgically removed
within a few hours by a doctor familiar with this
form of injury or gangrene may result.
REPLACING THE FUEL FILTER
An in-line filter is incorporated into the fuel line. Use the
following procedures should replacement become neces-
sary:
1. Close the fuel shut-off valve (Fig. 8).
2. Clamp both fuel lines that connect to the fuel filter
so gasoline cannot drain when lines are removed.
3. Loosen the hose clamps at both ends of the filter
and pull the fuel lines off the filter.
