6. Fill the reservoir to the proper level; refer to Check
Hydraulic System Fluid.
7. Place all controls in neutral or disengaged position and
start engine. Run engine at lowest possible RPM to
purge the system of air.
8. Run engine until lift cylinder extends and retracts and
forward and reverse wheel motion is achieved.
9. Stop the engine and check the oil level in reservoir,
add oil if necessary.
10. Check all connections for leaks.
Changing the Hydraulic Oil
Filter
The hydraulic oil filter keeps the hydraulic system
relatively free of contaminants. However, the hydraulic oil
filter must be serviced at regular intervals. The intervals
are: initially, after the first 5 hours of operation, and
thereafter every 250 hours of operation or yearly,
whichever comes first. Use a genuine TORO oil filter for
replacement.
1. Remove hydraulic oil filter from mounting head. Use
bottom type filter wrench (Fig. 36). Dispose of filter
properly.
2. Apply a film of oil on the gasket. Install filter by hand
until gasket contacts mounting head; then tighten filter
an additional 3/4 turn.
3. Start engine and check for oil leaks. Allow engine to
run for about 2 minutes so any air in system is purged.
Then shut engine off.
4. Check level of oil in reservoir; refer to Check
Hydraulic System Fluid, page 30.
Adjusting the Steering
1. Measure toe-in distance (at axle height) at front and
rear of steering tires. Front measurement must be
0–1/4 inch (6 mm) less than rear measurement.
2. Loosening jam nuts and rotating tie rod to adjust
clearance (Fig. 37).
3. Turn steering wheel full left to achieve a full left turn
(Fig. 37).
4. Check clearance between left tire and tie rod. There
should be 25 mm (1 in.) ± 6 mm (1/4 in.) clearance at
this position.
5. Loosening jam nuts and rotating steering rod to adjust
clearance (Fig. 37).
6. Rotate tie rod to move front of tire in or out.
7. Tighten jam nuts when adjustment is correct.
