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.
Always check of damaged or worn out parts before using the jack. Broken parts will affect
the jack operation. Replace or repair damaged or worn parts immediately.
Store idle jack. When jack is not in use, store it in a secure place out of the reach of children.
Inspect it for good working condition prior to storage and before re-use.
Do not force the trailer jack. Do not attempt to lift more than the 3500-lb. maximum lifting
capacity of this 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. Support the trailer tongue by the frame with jack stands.
3. If replacing an old jack, remove the old jack from the coupler, saving
the washers and bolts.
4. Insert the electric jack into the jack hole and aligning the bolt holes so
the motor housing is facing forward as show in Figure 1.
Tip: For extra clearance and convenience, the connector storage
bracket can be removed from the rear of the jack and installed on the
trailer, frame, or other convenient location.
5. Secure the jack with three Grade 5, 3/8in.-16UNC bolts and washers.
Place the star washers between the flat washers and the mounting
plate as shown in Figure 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.-lbs.
Tip: The salvaged bolts from the old jack are acceptable for reuse if
they are Grade 5 and in good condition.
6. If a lower support plate is not already present, install one in the bottom
of the trailer frame. Do not operate the jack without a lower support
plate.
7. Install the manual reset circuit breaker by either crimping or soldering

one of the wires to jack lead (Black). Connect the other wire to the positive terminal of the
battery. The breaker should be located as close to the battery as possible and stored inside the
battery box. Since the jack is internally grounded, a ground wire is not necessary.
REMOTE CONTROL
Before using remote control, you must press the ON button.
Press the UP button to extend the jack (raise the trailer).
Press the DOWN button to retract the jack (lower the trailer).
Warning: Always press the OFF button and slide the cover up
when not in use to lock the jack in place and prevent accidental
operation.
Disconnect the jack from the battery if the unit is not in use for
more than a few days in order to avoid discharging the battery.
If your battery becomes weak, the jack will extend more slowly, and the low voltage protection
feature will eventually cause it to stop operating. It will be necessary to recharge the battery, then
operate the jack in the opposite direction, at least momentarily, before you can continue to extend
the jack.
Tip: This device complies with Part 15 of the FCC Rules.
OPERATION
1. Park the trailer on a level surface and block the wheels.
Tip: For nighttime hookups, the light switch ON to illuminate your work area.
2. Before operating the jack, turn the foot with the 3/8” safety lock pin 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 UP. (You can press the DOWN button on the
remote control, per the remote control instructions)
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 DOWN. (You can press the DOWN button on
the remote control – see remote control instructions)
Note: The jack will stop automatically at the end of the extension or retraction stroke. 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. Before driving, remove the foot or position it in the highest position and completely retract the
jack.
MANUAL OPERATION (FOR BACK-UP AND EMERGENCY USE)
1. Disconnect the jack from the power source. (Failure to disconnect the power could result in

serious injury.)
2. Remove the level cap 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.
3. Rotate the manual crank handle counter-clockwise to extend the jack, and clockwise to retract
it.
MAINTENANCE
• Maintain your jack. It is recommended that the general condition of any jack be examined
before it is used. Keep your jack in good repair by adopting a program of conscientious repair
and maintenance. Have necessary repairs made by qualified service personnel.
• Keep all moving parts lightly lubricated to prevent corrosion.
• After use, wipe external surfaces of the tool with clean cloth.
