Installing Pedestal Tube
1. Turn the pedestal tube so that the plate lug (number 5 in Figure 13
below) faces south in the northern hemisphere and north in the
southern hemisphere. The plate lug is for attaching the guide for the
winch wire.
2. Place the washers and then the spring washers onto the previously
installed nuts. Lift the pedestal tube through the bolts onto the
washers.
3. Install the nuts with the washers and spring washers to the
foundation bolts.
4. Level the pedestal tube to vertical with the nuts that are under the
plate. For adjusting the level, use the appropriate wrench (30 mm)
and the spirit level to check that the pedestal tube is vertical.
5. Finally, tighten the bolts with the appropriate wrenches.
