enough ground clearance for the Jack, remove

the Jack entirely before towing trailer.

17. Do not use for aircraft purposes.

18. The warnings, precautions, and instructions

discussed in this instruction manual cannot

cover all possible conditions and situations

that may occur. It must be understood by the

Installation Instructions

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

Note: For additional information regarding the parts listed in the following pages, refer to Parts List and

Assembly Diagram on page 10.

Mounting

This Trailer Jack is designed specifically for use with

an A-frame hitch. Never attempt to mount this Trailer

Jack to a hitch or trailer not specifically designed for it.

An example of an A-frame hitch is shown in Figure A.

Check that the Outer Tube (1) of the Jack will fit into

the A-frame opening and that the Mounting Plate

holes align with the bolt locations on the trailer. Only a

qualified technician should modify the trailer if needed.

1. Block the wheels and support the trailer A-Frame

securely using jack stands (sold separately).

2. Insert the top of the Trailer Jack up through

the hole in the center of the A-frame hitch

from underneath until the top of the Mounting

Plate rests against the underside of the

hitch. Line up the holes on the Mounting Plate

with the bolt holes in the A-frame hitch.

3. Secure the Mounting Plate to the A-frame using

lock nuts, bolts and washers (all sold separately)

as listed under Hardware in the Specifications chart

on page 4. Slide a washer onto each bolt, then

insert them from the top side and attach a washer

and lock nut from the underside of the frame.

Tighten mounting hardware firmly to 15 – 20 ft. lb.

Use a torque wrench to confirm tightness.

Note: As an alternative, the Mounting Plate may be

welded into place on the underside of the A-frame

hitch by a certified welder. Welds must be properly

cleaned and painted when cool to prevent corrosion.

4. Insert the Foot Plate (11) over the bottom of

the Inner Tube (2). Insert the Lock Pin (12)

to secure the Foot Plate in place. Use the

spring clip on the Lock Pin to secure it.

Align bolt

holes

Insert Jack into A-frame opening

Figure A

5. Once the Jack is mounted to the trailer

tongue, attach the Crank (10) to the Jack

Screw (9) at the top of the Trailer Jack. Secure

Crank in place with the Bolt (7) and Lock

Nut (8). Securely tighten all hardware.

Operation Instructions

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this

manual including all text under subheadings therein before set up or use of this product.

Mounting the Trailer to the Towing Vehicle

1. Before mounting, chock the trailer wheels

to prevent the trailer from rolling.

2. Pull the Crank (10) out so that the knob is on

top. Rotate the Crank clockwise to extend the

Jack and raise the trailer hitch above the level

of the towing vehicle’s hitch ball. Once the

trailer is at the desired height, fold the Crank

over so that the knob is facing downward. This

will help keep the knob out of the way.

3. With the assistance of a spotter,

back the vehicle to the trailer.

4. Align the hitch ball directly under the trailer hitch.

5. Turn the Crank counterclockwise to retract

the Jack slightly, lowering the trailer and

transferring its weight onto the towing vehicle

until it is firmly seated on the hitch ball.

Tighten the trailer hitching mechanism.

6. Once trailer is fully engaged, continue to

retract Jack to its uppermost position. Retract

the Trailer Jack fully before towing the trailer.

Flip the Crank up and over when completed

to help keep the knob out of the way.

7. Attach the safety chain (sold separately).

Dismounting the Trailer from the Towing Vehicle

1. Before dismounting, chock the trailer wheels

to prevent the trailer from rolling.

2. Pull the Crank out so that the knob is

on top. Rotate the Crank clockwise to

extend the Jack and raise the trailer.

3. Continue to extend just enough for the Trailer

Jack to take the weight of the trailer. This will

make it easier to disengage the trailer hitch.

4. Disengage the trailer hitch and any

safety chains or other connections

between the vehicle and the trailer.

5. It may be necessary to extend the Jack further

to clear the trailer hitch. When the vehicle

is completely clear, and it is safe to do so,

drive the vehicle away from the trailer.

CAUTION: Have a spotter watch this operation

to be sure the trailer is clear of the vehicle.

6. Level the trailer by turning the Crank to raise

or lower the trailer to the desired height. Flip

the Crank up and over when completed

to help keep the knob out of the way.
