4. Installation Instructions
Follow these steps to replace the Off-Choke-Run switch knob on your Craftsman 3000i or 3300i inverter generator:
- Ensure Safety: Before beginning, ensure your generator is turned off, cooled down, and disconnected from any power sources or loads.
- Locate Existing Knob: Identify the Off-Choke-Run selector switch on your generator.
- Remove Old Knob: If an old knob is present, carefully remove any retaining screw (if applicable) and pull the knob straight off the shaft.
- Position New Knob: Align the new replacement knob with the metal shaft of the selector switch. Ensure the knob's internal shape matches the shaft's profile.
- Secure New Knob: Gently push the new knob onto the shaft. Once seated, insert the provided compatible screw into the center of the knob and tighten it securely with a screwdriver. Do not overtighten.

5. Care and Maintenance
This replacement knob is 3D printed from PETG material, known for its durability and strength, often exceeding that of standard PLA materials. Due to the nature of 3D printing, small residues from the manufacturing process may be present; these do not affect functionality.
- Cleaning: Wipe the knob with a damp cloth if it becomes dirty. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the generator in a clean, dry environment to prolong the life of all its components, including the knob.
6. Troubleshooting
If you encounter any issues during installation or if the knob does not fit correctly, please:
- Double-check that your generator model is indeed a Craftsman 3000i or 3300i.
