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 Motion Controls
Adjusting Handle Neutral
If motion control levers do not align, or move easily into
the console notch, adjustment is required. Adjust each
lever, spring and rod separately.
Note: Motion control levers must be installed correctly.
See Install Motion Control Levers on page 15.
1. Stop engine, remove ignition key and tilt seat forward.
2. Begin with either the left or right motion control lever.
Move lever to the neutral (but not locked) position and
pull lever back until the clevis pin (on arm below pivot
shaft) contacts the end of the slot (just beginning to put
pressure on spring) (Fig. 56).
3. Check where lever is relative to notch in console
(should be centered allowing lever to pivot outward to
the neutral lock position) (Fig. 56).
4. If adjustment is needed, loosen the nut against the
yoke.
5. Apply slight rearward pressure on the motion control
lever, turn the head of the adjustment bolt in the
appropriate direction until lever is centered in 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 nut and jam nut.
7. Repeat on opposite side of unit.

Adjusting Hydraulic Pump Neutral
Note: Adjust handle neutral first. That has to be correct
before the following adjustment can be made.
Danger
Mechanical or hydraulic jacks may fail to support
machine and cause a serious injury.
•
Use jack stand when supporting machine.
•
Do not use hydraulic jacks.
1. This adjustment must be made with drive wheels
turning. First raise the frame and block up so drive
wheels can rotate freely.
Engine must be running so motion control
adjustment can be performed. Contact with
moving parts or hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away from rotating parts, muffler and other
hot surfaces.
Warning
2. Slide seat forward, disconnect prop rod and tilt seat
fully forward.
3. Disconnect electrical connector from the seat safety
switch. Temporarily install a jumper wire across
terminals in the wiring harness connector.
