SAVE THESE INSTRUCTIONS FOR IMPORTANT SAFETY CONSIDERATIONS JACK USES AND CARE
- Do not modify the jack in any way. Unauthorized modification may impair the function and/or safety and could affect the life of the equipment. There are specific applications for which the jack was designed.
- Always check for damaged or worn out parts before using the jack. Broken parts will affect the jack operation. Replace or repair damaged or worn parts immediately.
- Do not force the trailer jack. Do not attempt to lift more than the maximum lifting capacity of 3500-lb.
- Never attempt to adjust the drop leg when there is any load on the jack. When using the drop foot or drop leg, 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 the safe operation of the jack.
-
Park the trailer on a level surface and block the wheels.
-
This trailer jack has been designed to attach to the top surface of the A-frame coupler.
-
Disconnect the trailer battery.
-
Detach the drop leg (#23) of the jack by removing the lock pin (#22) and sliding it out.
-
Position the drop leg (#23) in line with the mounting hole with the foot of the drop leg on the ground.
-
Support the trailer tongue by the frame with jack stands (not included).
-
If replacing an old jack, remove the old jack from the coupler, saving the washers and bolts.
-
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.
-
Secure the jack with three Grade 5, 3/8in.-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. -
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.
This unit includes a 7-way connector; just simply connect the 7-pin connector to the towing vehicle, no hard wiring required.
Tip: The trailer connector on the vehicle must match the trailer connector on the jack to power it.
Test that the correct terminal is receiving power with a test light. Number 4 on the connector will receive power. Connector number 1 is the neutral ground. Consult a qualified technician on replacing the connector if there is a mismatch between the vehicle and jack connectors. -
Check for proper installation by pressing the up/down switch for extending/retracting the jack. Also check that the light switch turns on the LED light.
-
After checking for proper operation, be sure to reattach the drop leg to the inner tube of the jack using the lock pin.
-
Retract the jack completely.
OPERATION
-
Park the trailer on a level surface and block the wheels.
Tip: For nighttime hookups, turn the light switch (#29) ON to illuminate your work area. -
Before operating the jack, extend the drop leg foot (#23) to the appropriate length and secure in place with the 3/8” safety lock pin (#22) provided.
WARNING: Do not stack blocks under the jack’s foot to increase the height. Stacked blocks may become unstable and fall. -
Extend the jack by pushing the operating switch (#30) UP.
Note: Under heavy use, the internal circuit breaker may open, causing the motor to switch off. In this case, release the operating switch, and wait 15 seconds for the breaker to reset before resuming operation. -
Retract the jack by pushing the operating switch (#30) DOWN.
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 the troubleshooting guide. -
After hitching the trailer to a tow vehicle, slide the drop leg (#23) fully into the jack tube, secure it with the safety lock pin (#22) and retract the jack tube. You may have to raise the jack tube slightly to release pressure on the safety lock pin.
-
Always check ground clearance before driving off.
MANUAL OPERATION INSTRUCTIONS
- If for any reason electric power is lost, disconnect the jack from the power source.
- Remove the rubber access cover on the top of the jack.
- Insert the manual crank handle into the access hole on the top of the jack, engaging the drive screw.
- Rotate the manual crank handle counter-clockwise to extend the jack, and clockwise to retract it.
MAINTENANCE
- The Electric A-frame jack motor is sealed and maintenance-free. It is important to maintain the electrical system including the battery and charger (not included).
- Ensure all connections are tight and free of corrosion and that the jack is properly grounded .
- Make sure the battery is fully charged prior to use.

ensure paint has been removed by the star washers.Direct metal-to-metal
contact must exist between mounting components to ensure good electrical
contact.Check electrical connections.
The trailer connector on the jack cannot get power from the trailer connector
on the vehicle| The trailer connector on the vehicle must match the trailer
connector on the jack to power it.
Test that the correct terminal is receiving power with a test light. Number 4 on the connector will receive power.
Connector number 1 is the neutral ground. Consult a qualified technician on replacing the connector if there is a mismatch between the vehicle and jack connectors.
