GSO Linear Bearing Focuser EAF Bracket Mounting Instructions:
Please follow carefully!
1.  With the bottom of the focuser pointing up to avoid falling, remove the 4 screws.
2.  Place the EAF bracket on the focuser and using the screws provided evenly tighten all 4 screws until they are snug.  Tighten 1/4 turn more, being careful to tighten all 4 screws evenly.
3.  Slide the coupler onto the focuser pinion shaft.
4.  Attach the EAF to the bracket.
5.  Tighten the set screws on the coupler.  Do not over tighten.

This bracket allows you to mount a ZWO Electronic Automatic Focuser (EAF)  onto your telescope.

The system consists of two parts:  a bracket for your telescope and a coupler that attaches the EAF onto the focuser pinion.  Connections are held securely with stainless steel M3 set screws.  Where necessary, bracket mounting screws are provided.  The ZWO supplied M4 screws are used to attach the EAF to the bracket. Note that the user will need to have a 1.5mm hex key for the M3 set screws (not provided).
