Before wiring, match the color of the motor terminals and power cable Connect the three short cables (red, black, yellow) to the color-coded terminals on the motor Connect the red long cable from the solenoid to the POSITIVE battery terminal and the long black cable to the NEGATIVE battery terminal Connect the other end of both to the motor Connect thin black wire (ground wire) from the solenoid assembly to the motor Remove socket cover on the solenoid and inset the plug of the remote control...
WINCH OPERATION 1. Disengage the clutch by moving the clutch handle to the disengaged position 2. Grab assembly hook with hand strap and pull cable NOTE: Always leave at least 5 turns of cable on the drum. Review safety warnings on page 1. 3.
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.

Self Recovery 1. Always attempt to get the steel cable 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.
The cable should be replaced immediately if there are any evident signs of fraying, burrs, or broken strands. Replace the cable with a Mile Marker recommended replacement part and make sure the cable is rated to sustain any load the winch is capable of pulling.
TROUBLESHOOTING Symptom Possible Cause Suggested Remedy Safety switch is OFF Turn safety switch ON Switch assembly not connected Insert switch assembly firmly to the connector properly Loose battery cable Tighten nuts on cable connectors Tap solenoid to free contact, applying 12 volts - Connection to coil terminal directly.
