Using the jack:
This jack should only be used to help stabilize a trailer with intact landing gear. The trailer must be parked on a
flat, concrete surface. The landing gear provides support for the trailer. One or more jacks can be used to stabilize
the trailer.
The load rating is displayed on the information label applied to the side of the jack (see Label 233, 234, or 265,
“Labeling diagram” on p. 6). Two ratings appear on the label: 1) “Static rating” which indicates how much weight the
jack will stabilize (NOT SUPPORT); 2) “Lifting” which is the amount of weight the screw mechanism of the jack can
lift.
Tip the jack onto its wheels and roll it under the hitch end of the trailer. If only 1 jack is necessary, position the
jack along the (lengthwise) center line of the trailer. If 2 jacks are necessary, position a jack under each front corner
of the trailer.
NOTE: Jacks should
also
be placed under each rear corner of the trailer if the distance from the rear axle to the
back end of the trailer is more than
1
/
4
of the overall trailer length.
Adjust the height of the jack to bring the top cap into firm
engagement with the underside of the trailer frame. Do not raise
the jack any higher than necessary because the landing gear
must always maintain solid contact with the ground in order to
provide support for the front end of the trailer. To adjust the height
of the jack, simply turn the crank handle clockwise. CJ-BEAM
model jacks have 2 raising/lowering speeds. To operate in high
speed mode, pull the crank handle toward you to extend the crank
shaft. To operate in low speed mode, push in the crank shaft.
Remove all jacks
before
hitching the trailer to a tractor. To
remove a jack, simply rotate the crank handle counterclockwise
until the top of the jack is no longer in contact with the underside
of the trailer. Grasp the handle, tip the jack onto its wheels, and
roll the jack out from underneath the trailer.
