Wanco® Metro™ Message Sign
Figure 4-3. Positioning the trailer
4.4.2 Leveling the trailer
Prior to raising the message sign display cabinet, the trailer must be level.
To level the trailer, refer to Figure 4-4 and follow these steps:
1. Block or chock the trailer wheels.
2. For each of the four leveling jacks at the corners of the trailer, pull the jack locking-pin
and rotate the jack downward. Release the pin and continue rotating the jack until it is
vertical. When the jack is properly set, the locking-pin snaps into position with an
audible “click.”
3. Determine which corner of the trailer is highest, and extend the jack foot on that corner
downward until it rests firmly on the ground. Then, level the trailer with the remaining
three corner jacks and, if desired for added stability, the drawbar jack.
