Before putting on CW, make sure the mount is at its zero position, i.e., CW shaft points to the ground.
Disengage the R.A. Gear Switch to set the R.A. axis free before loading the CW. Remove the CW
Safety Cap at the end of CW Shaft. Glide the CW over the shaft with the larger hole opening facing
down. Tighten the CW Locking Screw to hold the CW in place. Place the Safety Cap back onto the
shaft. Move the CW to the bottom of the shaft and tighten the CW locking Screw.
Figure 19. Install Counterweight
You may need more CW for heavier payloads, or a smaller CW for lighter scopes.

CEM40 is equipped with a 5” iOptron Universal Saddle. It can receive either a Vixen or a Losmandy-D
plate by flipping both Stationary Block and Locking Block. This unique adjustable dovetail saddle
enables the scope to sit at the center of the saddle.
The following graphics show how to change the dovetail saddle to fit either Vixen or Losmandy plate.
