shipping.
NOTE:
The set of holes nearest the safety rod hole will not take
a flat washer.
8. Raise toprail/leg assembly by pressing and walking the unit into the
upright position. Make sure the safety rod holes referred to in
Fig. 7
are still
aligned. Make sure both legs are still on the chalk lines.
9. Read the anchoring tip sheet before anchoring. Using the 3/4 carbide bit,
drill through the 4 holes in the base plate to a minimum depth of 4-1/2”. As
soon as you complete drilling a hole, set and drive an anchor bolt into the
drilled hole.
DO NOT TIGHTEN ANCHOR BOLTS YET !!
10. After drilling and setting all 4 anchors in the first post only, plumb the
post so that it is perpendicular. Use the level to check the post from side to
side, and front to back. You should also check distance measurements from
top of one leg to the top of the other leg, and from bottom to bottom. Adjust
legs to within 1/8”. Use shims sent in the packaging for shimming lift.
Keep shims as close to anchors as possible. Now you may tighten the
anchor bolts on first leg only.
Do not use an impact wrench.
Recheck for
plumbness and adjust if necessary.
11. After anchoring the first mainside leg, align the other mainside leg in
the chalk line. The leg may vary from the chalk line slightly. It is most
important that the legs be perpendicular and parallel with the other leg.
Check measurements at leg tops and bottoms again. Drill, set, and anchor
the other mainside leg. Level and plumb leg as before, then tighten anchors
on 2nd leg.
DO NOT DRILL OR ANCHOR OFFSIDE LEGS YET.
12. Set crossrails on 2 x 4 blocks in front of mainside legs, with the
machined crossrail connector towards the mainside leg as shown in
Fig. 8.
13. Use a fish tape to pull the crossrail chain through the crossrail tube. The
chain runs under the roller on the offside and over the roller on the mainside.
Repeat with the other crossrail. Feed the fish tape through the crossrail
starting from the mainside by going over the mainside roller and through the
crossrail tube, then under the offside roller and straight up.
See Fig. 8.
