Maintenance Tips
  • Inspect the cable regularly – check for frays, kinks, broken strands, or corrosion; replace if damaged.

  • Check electrical connections – ensure battery cables, terminals, and remote connectors are clean, tight, and free of corrosion.

  • Re-torque mounting bolts – verify all fasteners are tight after installation and periodically, especially after heavy-duty use.

  • Clean the winch – remove dirt, mud, sand, and salt from the cable, drum, fairlead, and winch body.

  • Lubricate moving parts – lightly lubricate fairlead rollers and other movable components for smooth operation.

  • Inspect the hook and attachments – ensure they are free of cracks, bends, or excessive wear before each use.

  • Operate the winch periodically without load – spool cable in and out to maintain smooth motor and drum operation.

  • Protect from moisture and corrosion – store in a dry location or cover the winch when not in use.

  • Monitor the winch during operation – avoid overheating; allow rest periods during heavy or continuous pulls.

  • Follow rated load limits – never exceed the 8,000β€―lb rated pull to prevent damage or safety hazards.
