the brake and replace worn parts in brake

Clutch slipping: Improper oil can cause the clutch to slip. Drain the winch and
refill with oil per the vendor’s specifications. Also, the clutch may be damaged or
worn. Disassemble the winch and replace faulty parts
WINCH WILL NOT RAISE LOAD
Check Capacity Chart to make sure load is not an overload. Check LML/Anti-two block
system to make sure it is functioning properly and not locking out the system. Check
system pressure relief and reset as required. Check pump flow and repair/replace pump
as required.
WINCH WILL NOT LOWER LOAD OR LOWERS ERRATICALLY
The winch brake should fully release between 340-400 PSI. Clean and replace the hose
as required. Disassemble the winch and replace faulty parts as required.
SWING INOPERATIVE OR ERRATIC

Swing park brake should fully release at 400 PSI. Replace hose and rebuild as
required. Erratic behavior may be caused by improper backlash between the gears



Rebuild swing box and replace slew bearing as required
SWING BRAKE DOES NOT HOLD
