WARNING: Please DO NOT rock the counterweight shaft rigorously. You’ll degrade the performance of the spring loaded gear meshing system, or even damage it.

WARNING: DO NOT fully lock the 2 Tension Adjusters during operations.

NOTE: The mount is shipped with latitude setting at high range (35º ~ 60º). If your site latitude is lower than 35º, please switch the latitude range before using.

STEP 1. Select Mount Latitude Range

Carefully remove the mount from the shipping box and familiarize yourself with the components shown in Figure 1.

The mount is by default shipped with the Long Latitude Adjustment Knob installed (for 35-60º). At lower latitudes of 0-35º, the Short Latitude Adj. Knob needs to be used. To change this knob, remove the Latitude Locking T-bolts on both sides (do not lose the 4 washers). Unscrew Bottom Post Locking Screw to free the Bottom Latitude Adj. Post and remove the Latitude Adj. Knob. Thread in evenly the adequate Latitude Adj. Knob to Top and Bottom Latitude Adjustment Posts. Reinstall and tighten bottom locking screw. Lastly, with 4 washers all properly placed, insert and tighten Latitude Locking T-bolts into the upper threaded holes.

STEP 2. Tripod Setup

Expand the tripod legs. Adjust the tripod height by unlocking and re-locking the Tripod Leg Locks to desired height. Position the tripod so that the Alignment Peg faces north, if you are located at northern hemisphere. If you are located in southern half, face the Alignment Peg south. Thread the tripod center rod into the tripod head and install the Accessory Tray and tread the Tray Locking Knob onto it. Do not fully tighten the Tray Locking Knob.

There are two threaded holes on the tripod head for alignment peg installation. The Alignment Peg may be moved to the opposite position shall the mount hit the tripod leg when used at a high latitude.
