- Remove Old Jack (if applicable): If replacing an existing jack, remove the old unit by unbolting it from the trailer tongue.
- Position the New Jack: Place the Uriah Products UC500010 Electric Trailer Jack onto the trailer tongue bracket. Ensure the mounting holes align.
- Secure the Jack: Insert the provided bolts through the mounting holes and secure with washers and nuts. Tighten all hardware securely according to torque specifications (if available from trailer manufacturer).
- Connect Power: The jack features an integrated 7-way connector. Plug this connector directly into your tow vehicle's 7-way receptacle. Ensure a secure connection. The jack draws 12V DC power from the vehicle's electrical system.

6. Operation
The Uriah Products UC500010 Electric Trailer Jack is designed for straightforward operation.
- Power Connection: Ensure the 7-way connector is securely plugged into your tow vehicle's 7-way receptacle. The vehicle's ignition may need to be on to supply power to the jack.
- Operating the Jack: Locate the control switch on the jack housing. This switch typically has two positions: UP and DOWN.
- To extend the jack leg (raise the trailer), press and hold the switch in the UP position.
- To retract the jack leg (lower the trailer), press and hold the switch in the DOWN position.
- LED Light: The jack is equipped with an LED light for illumination during low-light conditions. A separate switch or button typically controls this light. Activate it as needed for visibility.
- Manual Operation: In case of power failure or electrical issues, the jack can be operated manually. Remove the rubber plug on top of the jack housing to access the manual crank shaft. Insert the provided manual crank handle and turn it clockwise to extend the jack or counter-clockwise to retract it.

7. Maintenance
Regular maintenance ensures the longevity and reliable performance of your electric trailer jack.
- Cleaning: Keep the jack housing and leg clean from dirt, mud, and debris. Use a damp cloth to wipe surfaces. Avoid using harsh chemicals that could damage finishes or seals.
- Lubrication: Periodically inspect the inner and outer tubes for smooth operation. A light coating of silicone spray or a similar lubricant on the exposed inner leg can help maintain smooth movement. Do not over-lubricate.
- Electrical Connections: Regularly check the 7-way connector and its wiring for any signs of corrosion, fraying, or damage. Ensure connections are tight and secure.
- Protective Cover: When not in use, especially during storage or extended periods outdoors, use a protective cover to shield the motor housing and electrical components from weather elements.
- Hardware Inspection: Periodically check all mounting bolts and nuts for tightness. Re-tighten if necessary.
