(1)Remove CW Shaft Locking Screw from the CW Mounting Nose.
(2)Insert CW shaft into the CW Mounting Nose as indicated in 2nd photo below.
(3)Lock it using CW Shaft Locking Screw from the other side of the CW Mounting Nose. Tighten the Front CW Positioning Screw which is located in front of the CW Mounting Nose.
If the latitude of the observation location is lower than 10º, thread in the Rear CW Position Screw (a hex head set screw) before tightening the Front CW Positioning Screw to avoid CW hit tripod legs. Then tighten the Front CW Positioning Screw.

STEP 6. Install Counterweight
Remove CW Safety Cap at the end of CW Shaft. With the wider opening towards the shaft end, guide CW through the shaft. Use the CW Locking Screw to hold the CW in place. Place Safety Cap back onto the shaft. ZEQ25 comes with a 10.4 lbs (4.7kg) counterweight. It should be able to balance a total payload of about 13 lbs (6kg) for a 6” diameter telescope. An optional CW or extension bar is needed for a heavier payload or a larger diameter Telescope.
STEP 7 Attach and Balance an OTA on the Mount Connect Cables
After attaching an OTA and accessories to the mount, the ZEQ25 mount must be balanced in both R.A. and DEC axes to ensure minimum stress on the mount (such as gears and motors inside).
CAUTION: The telescope may swing freely when the R.A. or DEC Gear Switch is released. Always hold on to the OTA before you release the gear switch to prevent it from swinging. It can cause personal injury or damage to the equipment.
Release Tension Adjuster by turning it counterclockwise. Turn Gear Switch knob 90 degree to OPEN position to disengage the worm from the worm wheel.
