• Never attempt to adjust the footpad when there is any load on the jack. When using the foot pad make certain the supplied pin is fully inserted through both sides of the inner tube and the drop tube before using the jack.

INSTALLATION INSTRUCTIONS

Before installation, compare the lift capacity of the electrical jack with your trailer to ensure safe operation of the jack.

1. Park the trailer on a level surface and block the wheels.

2. This trailer jack has been designed to atta ch to the top surface of the A frame coupler.

3. Disconnect th e trailer battery

4. Detach the foot pad 15 ) of the jack by removing the lock pin 13 ) and sliding it out.

5. Position the foot pad 15 in line with the mounting hole with the foot of the foot pad on the ground.

6. Support the trailer tongue by the frame with jack stands (no t included)

7. If replacing an old jack, remove the old jack from the coupler, saving the washers and bolts.

8. Insert the electric jack through the A frame coupler hole and align the bolt holes so the motor housing is facing forward towards the tow vehicle.

9. Secure the jack with three Grade 5, 3/8 in. 16UNC bolts and washers. Remove paint from around one bolt hole on the jack, and from around the matching bolt hole on the trailer tongue. If the paint layer is thick, add a flat washer between the jack and the trailer to provide good contact. Exposed metal can be painted after assembly to prohibit corrosion. Bolts should be tightened to 15 20 ft. lbs.
   Tip:
   The salvaged bolts from the old jack are acceptable for reuse if they are Grade 5 and in good condition.

10. Connect the BLACK wire lead from the jack directly to the positive (+) terminal of the battery or junction box. This unit has a built-in circuit breaker which automatically trips and resets if the amperage is too high Now connect the WHITE ground wire to the negative ( (–) battery terminal or to the trailer frame

11. Check for proper installation by pressing the up/down switch for extending/retracting the jack.

12. After checking for proper operation, be sure to reattach the foot pad to the inner tube of the jack using the lock pin.

13. Retract the jack completely.

OPERATION

1. Park the trailer on a level surface and block the wheels.

2. Before operating the jack, extend t he foot pad 15 to the appropri ate length and secure in place with the 3/8” safety lock pin 13 provided.

   Note
   : If you attempt to extend or retract the jack and it does not respond, it may be at the end of the stroke. If the jack fails to respond, try operating it in the opposite direction. If it will not operate in either direction refer to th e troubleshooting guide. For FORD owners refer to the troubleshooting manual for important installation information.
