  • Page 2: Safety Warnings

    SAFETY WARNINGS LEARN TO USE YOUR MILE MARKER WINCH: After winch has been installed, take some time and practice using it so you will be familiar with ALL OPERATIONS. Periodically check the winch installation to ensure that all bolts are tight. To ensure proper operation, carefully inspect for any damaged parts before operating the winch.
  • Page 3 PRECAUTIONS Keeps hands and body away from roller or hawse fairlead (steel cable/synthetic rope intake slot) when operating. Secure vehicle in position before using winch. Do not exceed winch load weight capacity. Be certain winch is properly bolted to a structure (or vehicle) that can hold the winch load. Always use proper couplings when connecting winch steel cable/synthetic rope hook to load.
  • Page 4: Getting Started

    3. Torque the capscrews to about 35 ft-lb (47.5 N-m) 4. All Mile Marker mounting systems come pre-drilled with fairlead holes. If you are using any other mounting platform, drill two holes for the roller fairlead installation. Position the holes so the fairlead opening hole stretches from the circumference of the drum to the end of the maximum permissible layers on the drum in the direction cable is being rolled.
  • Page 5: Clocking Instructions

    CLOCKING INSTRUCTIONS Winch gear housing can be clocked in 8 positions, enabling the user to position the clutch lever at 8 equidistant locations (0°, 45°, 90°….360°). (Fig. 1-1) 1. Remove gear housing from tie bars (Fig. 1-2) 2. Remove the 8 bolts in the gear housing leg (Fig. 1-3) 3.
  • Page 6: Control Box Installation

    CONTROL BOX INSTALLATION NOTE: For best results, Mile Marker recommends mounting the control box to the winch, either over the motor or over the tie bars. If you choose to mount the control box within your vehicle, ensure that the location does not interfere with any moving or functioning parts of your vehicle and that electrical cables with similar specifications to Mile Marker’s are used.
  • Page 7 Mounting Control Box on Tiebars 1. Mount the control box to mounting brackets using 10 mm wrench (Fig 2-8) 2. Mount control box on the tie bars by attaching front end first and pushing down to snap in the back end (Fig. 2-9) 3.
  • Page 8: Wiring Instructions

    WIRING INSTRUCTIONS Wiring the Control Box 1. Slip the boots onto pertinent cables and make electrical connection in accordance with the schematic on following page. Slide the boots onto all the electrical connections made (Fig. 2-12 through 2-14). 2. Run battery power cables carefully under hood of vehicle, avoiding interference with moving parts and abrasion points which could potentially cause electrical short.
  • Page 9: Winch Operation

    CAUTION: Before using your new Mile Marker electric winch, rewind the entire steel cable/synthetic rope on the drum under a load of at least 500 lbs (227 kg) starting with at least 5 wraps of steel cable, or 10 wraps of synthetic rope on the initial layer. Failure to do so will result in the outer wraps pressing against the inner wraps, damaging the steel cable/synthetic rope.
  • Page 10: Winching Tips & Techniques

    Safety Tips • DO NOT DISENGAGE CLUTCH LEVER WHEN THERE IS A LOAD ON THE WINCH. Mile Marker electric winches utilize an automatic load holding brake, therefore no adjustment to clutch is needed to maintain load.
  • Page 11 Self Recovery 1. Always attempt to get the steel cable/synthetic rope as straight as possible to the direction of the vehicle. It is acceptable to start a pull at an angle if it is obvious that the vehicle will turn towards the hook anchoring point. Turning the steering wheel will assist the process. It is recommended that the driver is in the vehicle.
  • Page 12: Winch Maintenance

    WINCH MAINTENANCE • All moving parts within the electric winch have been lubricated using high temperature lithium grease at the factory. No further internal lubrication is required for the life of the winch. •If using steel cable, lubricate the steel cable periodically using light penetrating oil •...
