Wanco® Metro™ Message Sign
4. Check tires, wheels, and axle lock:
a. Check tires for wear. Replace worn tires.
b. Ensure tires are inflated to the proper pressure.
c. Verify all wheel lugs are in place and tightened. Do not tow the trailer if a wheel lug
is missing.
d. Remove the axle lock bar, if installed.
5. Check the drawbar, tow hitch, and safety chains:
a. Ensure the tow hitch on the tow vehicle is rated for weight equal to or greater than
the message sign’s gross vehicle weight rating (GVWR). The GVWR is listed on the
vehicle identification tag.
b. Ensure the tow hitch on the tow vehicle and the drawbar hitch on the message
sign trailer are compatible.
c. Inspect the tow hitch and drawbar hitch for wear and damage. Replace or repair if
necessary.
d. Ensure the trailer’s removable drawbar is attached securely to the trailer frame with
two sets of bolts, washers, and nuts. The bolts should engage the drawbar and the
nuts should be tight. (For drawbar installation instructions, see Section 3, page 9.)
e. Lower the drawbar jack into the down position by pulling the jack locking-pin and
rotating 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.” Use the hand-crank on the jack to lower the jack foot to the ground.
f. Verify the trailer’s four corner leveling jacks are in the up position and secured with
their locking-pins. To raise the leveling jacks, use the hand-crank on each jack to
raise the jack foot off the ground, then pull the jack locking-pin and rotate the jack
upward. Release the pin and continue rotating the jack until it is horizontal and the
pin reengages with an audible “click.”
g. Use the drawbar jack to raise the front of the trailer and set the drawbar hitch on
the tow vehicle hitch. Ensure the coupling is properly engaged and locked.
h. Raise, rotate, and lock the drawbar jack in the up or horizontal position.
i. Verify approved safety chains are attached properly to both the trailer and tow
vehicle, as illustrated in Figure 4-2. The chains should cross underneath the tow
hitch.
6. Ensure the trailer brake lights, taillights, and directional/turn indicators are connected
and functioning properly.
7. Remove blocks or chocks from wheels.
8. Follow the towing requirements in Section 4.3.2.
