Bleeding the Hydraulic System
The traction system is self bleeding, however, it may be
necessary to bleed the system if fluid is changed or after work
is performed on the system.
1.
Raise the rear of the machine so that the wheels are off
the ground and support with jack stands.
2.
Start the engine and run at low idle speed and engage
the lever and traction on 1 side and spin the wheel by
hand.
3.
When the wheel begins to spin on its own, keep it
engaged until the wheel drives smoothly (minimum 2
minutes).
4.
Check the hydraulic-fluid level and add as required to
maintain proper level.
5.
Repeat this procedure on the opposite wheel.
Checking the Hydraulic Hoses
Service Interval:
Every 100 hours
Check the hydraulic hoses for leaks, loose fittings, kinked
lines, loose mounting supports, wear, weather and chemical
deterioration. Make necessary repairs before operating the
machine.
Note:
Keep areas around the hydraulic system clean from
grass and debris buildup.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
•
If hydraulic fluid is injected into the skin it
must be surgically removed within a few hours
by a doctor familiar with this type of injury.
Gangrene may result if this is not done.
•
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.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
•
Make sure that all hydraulic-fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
Setting the Hydraulic Pump
Neutral Position
Note:
Adjust the handle neutral first. That needs to be
correct before the following adjustment can be made.
This adjustment must be made with drive wheels turning.
DANGER
Mechanical or hydraulic jacks may fail to support
the machine and cause a serious injury.
•
Use a jack stand when supporting the machine.
•
Do not use hydraulic jacks.
WARNING
The engine must be running so that you can adjust
the motion control. Any contact with moving parts
or hot surfaces may cause personal injury.
Keep your hands, feet, face, clothing and other body
parts away from rotating parts, muffler and other
hot surfaces.
1.
Raise the frame and block up the machine so that the
drive wheels can rotate freely.
2.
Disconnect the electrical connector from the seat
safety switch. Temporarily install a jumper wire across
terminals in the wire-harness connector.
3.
Unlatch the seat and slide seat forward.
4.
Disconnect the seat rod and tilt the seat fully forward.
Setting the Right Hydraulic Pump
Neutral Position
1.
Start the engine, open the throttle 1/2 way and
disengage parking brake; refer to
Off the Engine (page 24)
.
Note:
The motion-control lever must be in neutral
while making any adjustments.
2.
Adjust the pump rod length by rotating the knob, in the
appropriate direction, until the wheel is still or slightly
creeping in reverse (
3.
Move the motion-control lever forward and reverse,
then back to neutral.
Note:
The wheel must stop turning or slightly creep
in reverse.
4.
Open the throttle to
FAST
.
Note:
Make sure that the wheel remains stopped or
slightly creeps in reverse; adjust if necessary.
