Setup and Assembly
The Yuly CIY GAS67 is a barebones kit, requiring the user to install switches and keycaps. Follow these steps for proper assembly:
- Prepare the PCB and Plate:
Place the soundproof silicone pad and bottom sound-absorbing cotton onto the keyboard case. Ensure the PCB is aligned correctly with the metal positioning plate. Install the included keycap stabilizers onto the PCB if they are not pre-installed.

- Install Switches:
Align the pins of your chosen 3-pin or 5-pin MX-style mechanical switches with the hot-swappable sockets on the PCB. Gently press each switch into place until it clicks securely. Ensure the pins are straight to avoid bending.

Maintenance
Proper maintenance ensures the longevity and performance of your mechanical keyboard kit.
- Cleaning Keycaps: Remove keycaps using a keycap puller. Clean them with a mild soap solution and a soft cloth, then dry thoroughly before reattaching.
- Cleaning Switches: Use compressed air to remove dust and debris from around the switches. For deeper cleaning, switches can be carefully removed using a switch puller.
- Case Cleaning: Wipe the ABS case with a soft, damp cloth. Avoid harsh chemicals that may damage the finish.
