1.
Place the base rails on a flat level surface and insert and lock the side rail plates into the base rail
holes as shown in drawing # 1.
2.
Loosely bolt the saddle bracket (5990) to the side rails using the 1/2" x 1 1/2" bolts, flat washers,
and lock nuts provided in the 6005 bolt package.
3.
Loosely bolt the cross braces to the side rails using only 1/2" x 1 1/2" bolts and lock nuts (no flat
washers). NOTE: A flat washer under the head of the bolts would prevent the locking pins from
pivoting around far enough to allow the pins to release from the base rails.
4.
Tighten all the bolts.
5.
Unlock and remove the hitch assembly from the base rails and put to the side for later.
IMPORTANT NOTE: Apply a little grease or lubricant to the part of the pins that insert into the base
rails to help maintain smooth operation and rotation of pins and to protect from the elements. Turn the
pins occasionally to prevent them from seizing.
