7. With the Deck Assembly fastened to the decking material
and still upside down, place a Side Retainer lip on the deck-
ing, flush with the front of the decking. Mark the Side Re-
tainer mounting holes. Repeat this for the other Side
Retainer. Place a Front Retainer on the decking at the front,
with the flange butted up to the decking side. Mark the Front
Retainer mounting holes. Repeat this for the other Front Re-
tainer. Drill all marks with a 5/16" drill bit. Bolt the Side and
Front Retainers to the Deck Assembly. Bolt the Side and
Front Retainers together at the corners. The Front Retainers
have slotted holes at the center that will align to bolt them
together if using a decking with a width of 28", 30", 32", 35",
39", 40", 44" or 48". If using a decking with a non-standard
width, it will be necessary to drill a set of 5/16" holes to fas-
ten the Front Retainers together. Bolt the Front Retainers
together (see Figure 6.).
8. With the help of another person, upright the Deck Assem-
bly and slide it into the Base Assembly while holding the
black release handle out. Install the two 3/8" x 4" Safety
