IMPORTANT SAFETY CONSIDERATIONS
JACK USE 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. In addition, any unauthorized modification will void the warranty.
• 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
5000-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 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 attach to the top surface of
the A-frame coupler.
3. Disconnect the trailer battery.
4. Detach the drop leg (#23) of the jack by removing the lock pin (#22)
and sliding it out.
5. Position the drop leg (#23) in line with the mounting hole with the
foot of the drop leg on the ground.
6. Support the trailer tongue by the frame with jack stands (not
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"-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.

INSTALLATION & OPERATION MANUAL

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.
Also check that the light switch turns on the LED light.
12. After checking for proper operation, be sure to reattach the drop leg 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.
Tip: For nighttime hookups, turn the light switch (#3) ON to illuminate your work area.
2. 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.
3. Extend the jack by pushing the operating switch (#4) 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.
4. Retract the jack by pushing the operating switch (#4) 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.
5. 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.
6. Always check ground clearance before driving off.
MANUAL OPERATION INSTRUCTIONS
1. If for any reason electric power is lost, disconnect the jack from the power source.
2. Remove the rubber access cover on the top of the jack.
3. Insert the provided manual crank handle into the access hole on the top of the jack, engaging
the drive screw.
4. Rotate the manual crank handle counter-clockwise to extend the jack, and clockwise to retract it.
MAINTENANCE
1. 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).
2. Ensure all connections are tight and free of corrosion and that the jack is properly grounded.
3. Make sure the battery is fully charged prior to use.

TROUBLESHOOTING
Refer to below troubleshooting guide if the device does not function properly or parts are missing. If
unable to do so, have a qualified technician service the device.
Failure Possible Cause Corrective Action
Motor
will not
operate
Or light
is OK,
but jack
will not
operate.
No or Low Voltage
Check battery & electrical connections. Must have
minimum of 10 VDC. If the battery is low, plug the trailer
cable into the tow vehicle, and start the tow vehicle to
provide power to the jack.
Poor Ground
Clean area between the jack mounting plate and coupler,
and 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.
