  • Page 5: Getting Started

    Unpacking Your Winch Unpack your new Mile Marker winch and ensure that all the parts are included by referring to parts list and exploded view drawings provided in this manual. NOTE: If you find any missing or broken parts, please call Mile Marker as soon as possible at the number present on the front page of this manual.
  • Page 6: 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°). 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 7: Control Box Installation

    CONTROL BOX INSTALLATION NOTE: Your Mile Marker Control Box can either be mounted to the winch or in a remote location. However, Mile Marker recommends you to mount it to the winch following the instructions below. If you choose to mount it in a remote location, please ensure that: (a) the location does not interfere with any vehicle’s moving/functioning parts, and (b) you use electrical cables with similar or better specifications...
  • Page 8 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 10: Winch Operation

    CAUTION: Before you start using your new Mile Marker winch, you will have to re-wind the entire cable on the drum under a load of at least 500 lbs (227 Kg) starting with at least 5 wraps on the initial layer. Failure to do so will result in the outer wraps pressing against the inner wraps resulting in the damage of the cable.
  • Page 11: Winching Tips & Techniques

    Safety Tips • NEVER 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 12 The cable should be replaced immediately if any sign of burrs or broken strands are evident. A frayed cable with broken strands should be replaced immediately. Always replace the cable with a Mile Marker recommended replacement part. Any substitution must be IDENTICAL in strength, quality, lay and stranding.
  • Page 13: Winch Maintenance

    •After every use of the winch, inspect the cable for damages such as kinks, broken strands etc. When damaged, replace the cable immediately! CAUTION: It is recommended that you replace the cable with superior Mile Marker cables. If replacing from other sources, carefully compare for the maximum load capacity of the cable with that mentioned in the Specifications Section of this manual.
