8787780 3,500 LB 12V DC ELECTRIC A-FRAME TRAILER JACK
IMPORTANT! Before installation, compare the trailer jack's
rated lift capacity with your trailer to ensure safe operation.
1. Park the trailer on a level surface and block the wheels.
2. Support the trailer tongue by the frame with jack stands.
3. Remove the lock pin (#22) and slide the drop leg (#23) out
of the jack. Set aside.
4. Insert the trailer jack into the jack hole and align the bolt
holes so the motor housing is facing forward. The jack
attaches to the A-frame coupler's top surface.
4.1 You may remove the connector storage bracket (#17)
and install on the trailer or frame.
5. Scrape the paint away around the bolt holes to ensure there is
metal-to-metal contact.
6. Slide a flat washer (#20) onto each bolt (#19).
7. Drop a bolt into each of the three bolt holes. Twist a nut
(#26) onto each bolt and tighten to a torque of 15 to 20 ft-lb.
8. Fix the excess 7-way connector (#21) wire to the frame with
cable ties.
9. The trailer connector on the vehicle must match the trailer
connector on the jack to power it. This unit has a built-in
circuit breaker which automatically
trips and resets.
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 (Fig. 1).
