WARNING: 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 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, aligning the bolt holes so the motor housing is facing forward as
shown in Figure 1.
5. Secure the jack with three (3) grade 5, 3/8"-16 UNC bolts and washers (Not provided in the kit). Place the
star washers between the flat washers and 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·lb.
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 bottom of the trailer frame. Do not operate
the jack without a footpad.
7. If an additional fuse holder will be installed (Not provided in the kit), install the fuse holder as close as
possible to the positive terminal of the power source by either crimping or soldering the connections.
8. Connect the jack wire to the fuse holder. Since the jack is internally grounded, a ground wire will not be
needed.
Warning: When using an extension wire, DO NOT use a wire smaller than #10 gauge.
Park your trailer on a leveled ground and secure all trailer wheels.
1.
Tip: For nighttime operations, flip the light switch ON to illuminate your work area.
Before operating the jack, secure the footpad with the safety pin and cotter pin provided in the kit.
2.
Warning: Do not stack blocks or lumber under the jack's foot pad to increase the height as they
may become unstable and eventually collapse.
Extend the jack by pushing the operating switch UP. Retract the jack by pushing the operating switch DOWN
3.
Note: Under heavy use or exceed the STOP limiting mark when retract, the internal breaker may be triggered, causing the motor to turn
off. In this case, release the operation switch immediately, and wait a couple minutes for the breaker to reset.
Note: The jack will slow down and stop as it approaches the fully retracted position. Release the switch as soon as possible when the jack
stars slowing down.
Warning: DO NOT retract the jack exceeding the STOP limiting mark, otherwise may result in damage of the jack.
Before moving the trailer, remove the footpad or position it in the highest position and completely retract the jack.
