INSTALLATION & OPERATION MANUAL
5
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.
