attitude, tighten all of the nuts and bolts securely. With the weight distribution

engaged, begin with the angle set bolt, and tighten it until it comes back into

solid contact with the shank plus 1/4 turn. Uncouple the trailer, then tighten

all other bolts and nuts to the proper torque specs. Tighten both 3/4” shank

bolts to 250 ft‑lbs. torque.

Double check the nuts holding the L-brackets to make sure they are tight,

and also the bolts holding the sway bracket assembly to the trailer to make sure

they are secure. Bolts holding the bracket to the frame should be torqued to

65ft‑lbs., and the nuts for the L-brackets should be torqued to 75ft‑lbs.

You are now ready to take the trailer out for a tow. Re-couple the trailer,

making sure the L-pins and clips on the sway brackets and the arm retainer pins

in the hitch head are secure. Remember to connect the safety brake cable, safety

chains, and electrical cables. Make sure your trailer brake control is correctly

adjusted. Retract the jack completely. Tow carefully at rst and pay attention to
