Setting Up the Tripod

The tripod comes fully assembled with the metal plate, called the tripod head, that

 

 

 

holds the legs together at the top. In addition, the brackets that support the acces-

 

 

 

sory tray are also attached to the tripod.

 

 

 

Stand the tripod upright and pull the tripod legs apart until the leg brace assembly

 

 

 

for the accessory tray is fully extended (see figure 2-2). The tripod will now stand

 

 

 

by itself. To increase the stability, tighten the bolts that hold the legs to the tripod

 

 

 

head (use the appropriate size wrench from the supplied set). This will help mini-

 

 

 

mize any flexure or wobble of the legs.

 

Adjusting the Tripod Height

Once the tripod is set up, you can adjust the height at which it stands. To do this:

1. Loosen the knob on the leg clamp so that the tripod leg can be adjusted.

2. Slide the center portion of the tripod leg away from the tripod head until it is at the desired height.

3. Tighten the knobs on each leg clamp to hold the legs in place.

With the tripod set up, you are ready to attach the accessory tray to the tripod.

Figure 2-2

Setting up the tripod requires nothing more than pulling the tripod legs away from the tripod head. The height at which the tripod stands can be adjusted by sliding the slats in the center of each leg toward or away from the tripod head.
