INSTALLATION INSTRUCTIONS
KEEP HANDS, FEET, AND BODY OUT FROM BENEATH THE
JACK & TRAILER TO AVOID THE RISK OF HARM OR FATAL
INJURY!
BEFORE INSTALLATION, COMPARE THE LIFT CAPACITY OF
THE TONGUE JACK WITH YOUR TRAILER TO ENSURE SAFE
OPERATION OF THE JACK.
1. Park the trailer on a level surface and block the trailer tires.
2. Support the trailer tongue by the frame with the jack stands.
3. Insert the electric jack into the jack hole, aligning the bolt holes
so the motor housing is facing forward as shown in Fig 1.
4. Attach the jack using three bolts (grade 5, 3/8"-16 UNC bolts
with washers and nuts or 3/8"-16 self-tapping bolts are
recommended). Place the star washers between the flat
washers and mounting plate as shown in Fig 1. The star
washers are intended to penetrate through the paint on
the mounting plate to ensure direct metal to metal contact.
Bolts should be tightened to 15-20 ft-lb.
5. If a lower support plate is not already present, install one in
the bottom of the trailer frame.

6. Attach foot with 3/8" safety lock pin. Be sure to insert pin through the complete assembly
closing safety.
7. Connect 7-pin connector to vehicle’s trailer plug, or if hard wiring connect the black positive
leadto the positive terminal of the battery. The electric tongue jack is internally grounded,
and needs no ground wire if A frame is properly grounded.
OPERATION INSTRUCTIONS
1. Park your trailer on a level surface and block all dolly and trailer tires.
Tip: For night time hookups, flip the light switch ON to illuminate your work area.
2. Before operating the jack, attach the foot with the 3/8" safety lock pin provided.
DO NOT stack blocks under the jack’s foot to increase the height. Stacked blocks may
become unstable and fall.
The jack must be applied with the original foot, otherwise the jack will be damaged.
3. Normal operation:
(1) Extend the jack by pressing the UP button.
(2) Retract the jack by pressing the DOWN button.
NOTE: The jack will not slow down and stop as it approaches the fully retracted
position. Release the switch at the first sign of slowing.
DO NOT retract the jack exceeding the STOP limiting mark, otherwise may result in
damage of jack.
4. Before driving, remove the foot or position it in the highest position and completely retract
the jack.
MANUAL OPERATION INSTRUCTIONS

retract it.
5. Remove manual crank handle and replace manual override plug.
MAINTENANCE
To keep your jack in good, functional condition, fully extend the jack and clean the inner jack
tube once a year. After cleaning, coat the tube with a light grease or silicone spray lubricant.
