Bleeding the Hydraulic System
The traction system is self bleeding; however, it may be
necessary to bleed the system if the fluid is changed or after
work is performed on the system.
1. Raise the rear of the machine so that the wheels are off
of the ground and support it with jack stands.
2. Start the engine and run it at idle speed. Engage the
traction on one 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 as it drops and add as
required to maintain the proper level.
5. Repeat this procedure on the opposite wheel.
Checking the Hydraulic Lines
After every 100 operating hours, check the hydraulic lines
and hoses for leaks, loose fittings, kinked lines, loose
mounting supports, wear, weather and chemical
deterioration. Make necessary repairs before operating.
Note: Keep the areas around the hydraulic system clean
from grass and debris buildup.
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 all hydraulic fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
hydraulic system.
Warning
Adjusting the Motion Controls
Adjusting the Handle Neutral
If the motion control levers do not align, or move easily
into the console notch, an adjustment is required. Adjust
each lever, spring, and rod separately.
Note: The motion control levers must be installed
correctly; refer to Installing the Motion Control Levers,
page 16.
1. Stop the engine, remove the ignition key, and tilt the
seat forward.
2. Begin with either the left or right motion control lever.
Move the lever to the neutral (but not locked) position
and pull the lever back until the clevis pin (on the arm
below the pivot shaft) contacts the end of the slot (just
beginning to put pressure on the spring) (Fig. 52).
3. Check where the lever is relative to the notch in the
console. It should be centered allowing the lever to
pivot outward to the neutral lock position (Fig. 52).
4. If an adjustment is needed, loosen the nut against the
yoke.
5. Apply slight rearward pressure on the motion control
lever and turn the head of the adjustment bolt in the
appropriate direction until the lever is centered in the
neutral lock position (keeping rearward pressure on the
lever will keep the pin at the end of the slot and allow
the adjustment bolt to move the lever to the appropriate
position).
6. Tighten the nut and jam nut.
7. Repeat on the opposite side of the unit.
