6. Press down on parking brake rod and push up on switch
until compressed length of switch plunger is .030"
(Fig. 38, inset) . This the distance between the brake rod
paddle and switch plunger housing.
7. Tighten switch mounting screws and nuts.
8. With parking brake disengaged, the switch circuit
should have continuity. If there is no continuity, move
switch down slightly until there is continuity.
9. Check adjustment as follows:
Engage the parking brake. Depress the traction pedal
while engine is running and the PTO lever is
disengaged. The engine should stop within 2 seconds. If
engine stops, the switch is operating correctly; thus,
continue operation. If engine does not stop, there is a
malfunction in the interlock system.
10. Install steering tower cover and brake rod knob.
Changing Hydraulic Oil And
Filter
Initially, replace the hydraulic system oil and filter after the
first full day's operation — NOT TO EXCEED 10
HOURS. Thereafter, replace the filter every 200 hours and
oil every 1000 hours.
The axle housing acts as the reservoir for the system. The
transmission and axle housing are shipped from the factory
with approximately 5 quarts (4.7 l) of high quality
hydraulic fluid. Check the level of hydraulic fluid before
the engine is first started and daily thereafter.
Appropriate hydraulic fluids are listed below.
