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.
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 AVOID THE HAZARD
•
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.
Adjusting Motion Controls
If motion control levers do not align, or move easily
into the console notch, adjustment is required. Adjust
each lever, spring and rod separately.
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 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. 30).
3.
Check where lever is relative to notch in console
(should be centered allowing lever to pivot
outward to the neutral lock position) (Fig. 30).
4.
If adjustment is needed, loosen the nut against
the yoke and while applying slight rearward
pressure on the motion control lever, turn the
head of the adjustment bolt in the appropriate
direction until lever is centered (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). Tighten lock nut.
5.
Repeat on opposite side of unit.
