Check Hydraulic Lines
After every 100 operating hours, check 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 areas around hydraulic system
clean from grass and debris build up.
POTENTIAL HAZARD
• Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
WHAT CAN HAPPEN
• Fluid accidentally injected into the skin
must be surgically removed within a few
hours by a doctor familiar with this form of
injury or gangrene may result.
HOW TO AV
OID THE HAZARD
•
Make sur
e all hydraulic fluid hoses and
lines are in good condition and all
hydraulic connections and fittings are tight
before applying pressure to hydraulic
system.
• 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.
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 19.
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. 42).
3. Check where lever is relative to notch in console
(should be centered allowing lever to pivot
outward to the neutral lock position) (Fig. 42).
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.
