To reduce the risk of property damage, serious personal injury, or death when using this jack, take the following precautions:

???Refer to your trailer owner's manual to verify the Trailer Max Tongue Weight does not exceed the maximum trailer jack load rating.

???During installation, do not place any part of your body under the trailer tongue. Only support the trailer tongue with jack stands rated for more than the tongue weight of your trailer.

???Only use this trailer jack on a hard, level surface capable of sustaining the load.

???Always block trailer wheels when using this trailer jack.

???Do not modify this trailer jack.

???Never allow children to play with or near the trailer jack while it is supporting the trailer.

???Never work under a trailer that is supported only by a trailer jack.

???Periodically inspect the jack fasteners, frame, and welds for looseness, cracks, or other damage. Do not use the jack if there is a problem.

???Never tow a trailer with the jack in the

"Down" position, and be sure to lock the jack in the "Up" position before towing.

???Always make sure that the trailer hitch receiver is fully connected and properly locked to the ball hitch before retracting this trailer jack.

Introduction

The Model T23121/T23122 Trailer Jack can be mounted to the tongue of a trailer with a tongue weight less than 1000 lbs (1500 lbs for the Model T23122). The pivoting mounting plate allows the jack assembly to swing out of the way and lock in place to prevent high-centering when towing.

Specifications

Installation

1.Read all safety precautions listed.

2.On a level surface, chock the trailer wheels, raise the trailer tongue at least 18" off the ground with a floor jack or other suitable lifting device, then use a jack stand to support the trailer tongue.

3.Identify a mounting location on one of the trailer tongue's main frame rails that meets the following requirements:

???Is perpendicular to the ground (vertical)

???Provides adequate clearance when con- necting the trailer to the tow hitch of the towing vehicle.

???Allows the jack to swing 90?? and lock in position when towing.

???Provides a clamping location for all four bolts and both clamping brackets (see

Figures 2???3).

???Prevents the jack from twisting or sliding during use.
