Step 2:
Fasten the upright weldments
(“
uprights”) to the yokes. Then fasten two beam clamps to the beam
bracket of each upright. NOTE: Models FHSN-6-20 and FHSN-8-20 require shim (28-113-022).
Lay the leg assemblies flat on the ground. Slide the uprights into the corresponding receivers of the yokes.
Align the pinhole in each upright with the pinhole in a yoke receiver as shown in Fig. 2A below. Use an adjustment
pin to attach each upright to a leg receiver. Remove the hitch clip from the end of the pin. Insert the pin through
the pin holes and reinstall the hitch clip.

Step 3:
Couple the I-beam to the uprights.
Insert the flange of the I-beam into the gap between the beam clamp and the top of each upright (beam bracket);
then secure the flange on the opposite side by installing the remaining beam clamp as shown in the diagrams
below.
