1. SPECIFICATIONS

2. USE INSTRUCTIONS

The standard model trailer stabilizing jack is intended to be used to support the ends of a semitrailer
that is parked against a loading dock and not connected to a truck’s fifth-wheel. The semitrailer must
be situated on a flat, stable, improved (preferably concrete) surface.

The load rating in pounds is shown on the information label located on the side of the jack. Two ratings
appear on the label:

1) A static rating= how much weight the jack will stabilize;

2) A lifting rating= how much weight the screw mechanism of the jack can lift.

NOTE: The need to use trailer stabilizing jacks, the number necessary, and the exact placement of

jacks under the semitrailer must be determined by a qualified person responsible for the loading or
unloading of the trailer.
