2. Setup and Installation
Proper installation is crucial for the performance and stability of your bass tuners. Follow these steps carefully.
Tools Required:
- Screwdriver (appropriate size for included screws)
- Wrench or socket (for ferrules, if applicable)
- Drill with small pilot bit (optional, for new screw holes)
- Measuring tool (for verifying headstock hole size)
Installation Steps:
- Prepare the Headstock: Ensure your bass guitar's headstock has holes designed to fit modern 13.7mm tuning machine holes. If replacing existing tuners, carefully remove the old hardware.
- Insert Tuners: Insert each QWORK bass tuning peg into the corresponding hole on the headstock. Ensure the orientation (2L + 2R) matches your bass guitar's headstock configuration.
- Secure with Ferrules: Place a ferrule over the shaft of each tuner on the front side of the headstock. Tighten the ferrule securely, but do not overtighten, to prevent damage to the headstock finish.
- Attach with Screws: Align the screw hole on the base of each tuner with the pilot hole on the back of the headstock. If no pilot hole exists, mark the position and drill a small pilot hole to prevent wood splitting. Secure each tuner with the provided screws. Caution: Do not overtighten screws to avoid stripping or damaging the wood.
- Final Check: Once all tuners are installed, gently test their movement to ensure they turn smoothly without obstruction.

3. Operating Instructions
Using your QWORK bass tuners for tuning is straightforward. The 1:19 gear ratio ensures fine-tuning capabilities.
Tuning Your Bass Guitar:
- String Installation: Thread your bass strings through the bridge and into the string post holes of the tuners. Ensure enough slack to wrap the string around the post a few times.
- Initial Tension: Wind the string around the post, keeping it taut. Turn the tuning key to increase tension until the string begins to produce a note.
- Fine Tuning: Use an electronic tuner or reference pitch to adjust each string to the desired note. Turn the tuning key slowly for precise adjustments. The 1:19 gear ratio allows for very accurate tuning.
- Stretch Strings: After initial tuning, gently pull each string away from the fretboard a few times to stretch it. Retune as necessary. Repeat this process until the strings hold their pitch.

4. Maintenance
QWORK bass tuners are constructed from durable metal alloy and feature sealed lubrication, requiring minimal maintenance.
- Cleaning: Wipe the tuners periodically with a soft, dry cloth to remove dust and grime. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: The tuners feature sealed lubrication, meaning they do not require external oiling. Attempting to lubricate them may introduce dust or debris and is not recommended.
- Check Tightness: Occasionally check the tightness of the mounting screws and ferrules. If any feel loose, gently tighten them. Do not overtighten.

5. Troubleshooting
If you encounter issues with your QWORK bass tuners, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Tuner feels loose or wobbly | Mounting screws or ferrule are loose. | Gently tighten the mounting screws and ferrule. Do not overtighten. |
| Difficulty turning the tuning key | Debris in the mechanism; overtightened ferrule. | Check for any visible debris and remove. Ensure the ferrule is not overtightened, which can bind the shaft. |
| Tuner slips or does not hold pitch | String not properly wound; worn internal gears (unlikely for new tuners); stripped screw hole. | Ensure strings are properly wound around the post. If a screw hole is stripped, consider using a slightly larger screw or filling the hole with wood filler and re-drilling a pilot hole. If the issue persists, contact QWORK support. |
