At very low-latitudes (<10°), to avoid CW bumping into tripod leg, turn the rear Low Latitude Position Screw (a hex head set screw) further into CW Mounting Housing before tightening the CW Shaft Positioning Screw and Shaft Locking Screw.

DO NOT rock the counterweight shaft rigorously. It may damage the worm system.

STEP 5. Installing the Counterweight(s)

Before installing the Counterweight, make sure that both R.A. and DEC Gear Switches are fully engaged to avoid sudden mount movements, which could injure yourself or damage the mount gear system.

Make sure the mount is at zero position (i.e. counterweight shaft is pointing to ground when the counterweight is installed.)

Remove the CW Safety Cap at the end of CW Shaft. Guide the CW over the shaft. Tighten the CW Locking Screw to hold the CW in place. Always place the Safety Cap back onto the shaft prior to use to prevent personal injury and/or equipment damage.

WARNING: The mount should always be kept in the zero position while it is being loaded with CWs and payload.

WARNING: The zero position is the only safe position the mount should stay in unless it is balanced.
