Refer to the assembly image(s) on the chassY PiCard or main website at makechassy.com 1. Grab a Main Rail (01), ensuring the narrow side of the keyholes face outwards. 2. Insert the Forward Cross Spar (02) into one of the forward square holes in the side of the Main Rail (01), with the YAIR logo facing up and towards you. 3. Now fit the Aft Cross Spar (03) into a square hole near the rear end of the Main Rail. 4. Fit the other Main Rail (01) onto Cross Spars (2 & 3) 5. If required, attach the Extension Rails (08) to the Forward Cross Spar (02). If not using the Extension Rails, they can be stored ('docked') by fitting them such that they face away from the front of chassY. 6. Depending on your setup, insert the Rests (5, 6 and/or 7) into the appropriate keyholes on top of the Rails then slide sideways to lock into position. 7. Add your device, and if appropriate, a keyboard. 8. Work or play! IF LIFTING CHASSY WITH YOUR DEVICES MOUNTED, ENSURE YOU GRIP THEM SO THEY DO NOT FALL OFF.
