The Power Tongue Jack is a device designed for use with travel trailer A-frame applications, facilitating the vertical movement of the trailer. It is an aftermarket kit that includes the Power Tongue Jack with a footpad and a manual crank handle.

Function Description:

The primary function of the Power Tongue Jack is to assist in hitching and unhitching a travel trailer from a tow vehicle by raising and lowering the trailer's coupler. It operates electrically, providing convenient and effortless vertical adjustment. In the event of power loss, the jack can be operated manually using the provided crank handle.

Important Technical Specifications:

Capacity: 3,500 lbs.
Stroke: 18 inches.
Power Rating: 30 Amp.
Fuse: Equipped with a 30A ATO-type in-line fuse for circuit protection.
Lighting: Features four LED lights for illumination, which can be controlled by an ON/OFF switch.
Gears: Utilizes helical cut gears to reduce noise and improve operating efficiency.
Switch: Enhanced rocker switch for improved durability.
Casing: Textured casing designed to protect against chips and cracks.

Usage Features:

Installation: The jack is installed by sliding its leg through the hole in the trailer's coupler and securing it with three 3/8" - 16 x 1" hex bolts. It requires connection to a grounded 12V power supply on the trailer and must be wired through a 30 amp fused circuit. The footpad is reattached to the jack leg using a clevis pin and hairpin cotter pin after installation.
Electrical Operation (Unhitching):
1. Chock the trailer tires.
2. Ensure the footpad is securely pinned.
3. Confirm the ground surface under the jack is firm and level.
4. Push the "EXT" (Extend) button to extend the jack until the footpad touches the ground and the coupler clears the hitch ball.
5. Disconnect all electrical and mechanical connections between the trailer and tow vehicle.
6. Move the tow vehicle away.
7. Push the "RET" (Retract) button as needed to level the front of the trailer.
Electrical Operation (Hitching):
1. Chock the trailer tires.
2. Press "EXT" if needed to allow the coupler to clear the hitch ball.
3. Push "RET" to retract the jack until the coupler properly mounts the hitch ball and the leg is fully retracted. It is crucial that the jack leg is fully retracted before moving the tow vehicle.
Light Control: An ON/OFF switch controls the jack's LED lights. Leaving the lights on for an extended period can drain the trailer's battery.
Manual Operation (Unhitching):
1. Chock the trailer tires.
2. Ensure the footpad is securely pinned.
3. Confirm the ground surface under the jack is firm and level.
4. Open the rubber plug on top of the gearbox to expose the manual drive shaft.
5. Insert the manual crank handle into the drive shaft.
6. Turn the crank handle clockwise until the trailer is supported and the coupler clears the hitch ball.
7. Move the tow vehicle away.
8. Lower the trailer to level by turning the crank handle counterclockwise.
9. Remove the crank handle and replace the rubber plug.
Manual Operation (Hitching):
1. Chock the trailer tires.
2. Ensure the footpad is securely pinned.
3. Open the rubber plug on top of the gearbox.
4. Insert the manual crank handle.
5. Turn the crank handle counterclockwise until the coupler properly mounts the hitch ball and the jack leg is fully retracted.
6. Remove the crank handle and replace the rubber plug. Ensure the jack leg is fully retracted before moving the tow vehicle.

Maintenance Features:

Fuse Replacement: The Power Tongue Jack is protected by a 30A ATO-type in-line fuse. If the fuse blows, it needs to be replaced. A fully charged battery is essential for proper operation, as low voltage can cause premature fuse blowing.
Clutch System: The jack incorporates a clutch as an overload protection mechanism for the motor. The clutch will slip under two conditions:
1. When the jack reaches its extend or retract limit.
2. If the trailer's tongue weight exceeds the jack's capacity limits.
- Troubleshooting Clutch Slippage: If the clutch slips due to excessive tongue weight, it is recommended to reorganize items stored in the trailer to reduce the load on the jack.
- Operation with Clutch: It is important to release the operating switch immediately when clutch noise occurs. The clutch should not slip during normal operation, as continuous slippage can lead to excessive wear on both the clutch and the motor.
Wiring Protection: All electrical wiring harnesses should be properly loomed and secured to prevent damage and installed according to RVIA electrical standards.
