HYDRAULICS
Periodically clean dirt and debris from the bottom side of the depth stop ring.
Inspect hydraulic hoses, fittings and cylinders for wear or leaks. Use a piece of cardboard or wood rather than
hands to search for suspected leaks. Replace if necessary.
Before applying pressure to the hydraulic system, be sure all connections are tight and that the hoses are not
damaged.
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive and their presence could present a hazard. Do
not check for leaks with your hand! High-pressure oil streams from
breaks in the line could penetrate the skin and cause tissue damage
including gangrene. To check for a hose leak, SHUT the unit ENGINE
OFF and remove all hydraulic pressure. Wear oil impenetrable gloves,
safety glasses and use cardboard to check for evidence of oil leaks. If
you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.
If oil does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure.
SLIP CLUTCH
NOTE: Remove the retaining bolt from the yoke linked to the slip clutch. This allows the slip clutch to float so
the adjustment can be made. Secure the retaining bolt after the slip clutch is adjusted.
If the rock wonderer has been left unused for a period of time, e.g. A month, or even less in
damp, wet conditions, the clutch friction liners may tend to bond to the clutch plates. To free
up the friction liners, the clutch springs should be backed off and the friction liners pried
away from their backing plates. It has been found that simply running the rock wonderer
with the slip clutches loose will not necessarily free up the friction liners and may in fact
cause them to become glazed. The springs should be tightened down to the heights
indicated in the following illustration.
As the friction liners on the slip clutch wear the springs may have to be readjusted. By tightening or loosening
the bolt running through the clutch springs the releasing torque of the clutch can be set. If the bolt is set too
tight the slip clutch will not slip and damage to the universal joint shafts will occur. Setting the bolt too loose will
cause excessive slipping and the friction plates will wear out quickly.
Refer to the following illustration and set the height of the clutch springs as indicated. Tighten nuts following an
alternating cross pattern. Check that the height is constant for all springs.
