Setting Up the Tripod:
The tripod legs come pre-assembled with the center leg support bracket attached to the inside of each tripod
leg. Each leg must then be attached to the tripod head of the equatorial mount.
1. Remove the tripod legs from their shipping box and place them horizontally on a flat surface.
2. Lie the metal tripod head on its side. Attach the three tripod legs one by one by sliding the bolt at the
top of each tripod leg into the slotted cut-outs located on the bottom of the tripod head. Tighten the
wing nuts on the end of the bolts to secure each tripod leg.
3. Stand the tripod with the tripod head attached on its feet and separate the tripod legs until the center
support bracket is fully extended.
Attaching the Accessory Tray
Next, attach the accessory tray to the tripod. Locate the accessory tray and the three wingnut screws to
attach the tray.
