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.
Change 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. 35). 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 34.
Adjust 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. 36).
3.
Turn steering wheel full left to achieve a full left
turn (Fig. 36).
4.
Check clearance between left tire and tie rod.
There should be 1 inch (25 mm)
(6 mm) clearance at this position.
5.
Loosening jam nuts and rotating steering rod to
adjust clearance (Fig. 36).
6.
Rotate tie rod to move front of tire in or out.
7.
Tighten jam nuts when adjustment is correct.
