2. TO ENGAGE CLUTCH, lift up knob then release. See warning label located by shifter knob. Run the winch in reverse until the shifter knob snaps fully in or until the cable drum starts turning. At this point make sure the shifter knob is all the way in. The plastic plug in top of clutch housing may be removed, for inspection of clutch to assure total engagement. After the clutch is fully engaged, the winch is ready for winching in the cable.
4. Check alignment of chain and sprockets and adjust as required to minimize wear. 5. Inspect the cable. If the cable has become frayed with broken strands, replace immediately. WINCH MAINTENANCE Adhering to the following maintenance schedule will keep your winch in top condition and performing as it should with a minimum of repair. A. WEEKLY 1. Check the oil level and maintain it to the oil level plug. If oil is leaking out, determine location and repair. 2.
HYDRAULIC SYSTEMS Refer to performance charts, below, to properly match your hydraulic system to the HD-234 winch performance. The charts consist of: 1. Line pull (lbs.) first layer vs. working pressure (PSI). STATIC (solid line) refers to hoisting a suspended load from rest; DYNAMIC (dashed line) refers to maintaining the motion of a moving load. 2. Line speed, first layer (FPM) vs. gallons per minute (GPM). Performance based on a motor displacement of 3.6 cubic inches with 15 GPM maximum flow rate.
1. Drag brake disc worn. 1. Hydraulic motor shaft seal. Cable birdnests when clutch is disengaged Hydraulic fluid leaks out hole in motor adapter 1. Replace damaged seal. 1. Replace Discs. 1. Replace motor. 2. Check flow rate. Refer to Hydraulic Systems flow chart page 7. Oil leaks from housing 1. Hydraulic motor worn out. 2. Low flow rate. 1. Replace seal. 2. Drain excess oil. Refer to Techniques of Operation. 3. Replace gasket. 1. Seal damaged or worn. 2. Too much oil. 3. Damaged gasket.
