- Adjust Height: The crutch is adjustable for users over 5 ft 1 in (155 cm). To adjust the height, locate the adjustment button on the shaft.

3. Operating Instructions
Using your KMINA Quad Crutch correctly is essential for safety and effective mobility. Always ensure the crutch is properly adjusted to your height before use.
- Walking with the Crutch: When walking, move the crutch forward first, then step with your affected leg, followed by your unaffected leg. Maintain a steady rhythm. The 4-prong base provides enhanced stability, allowing for confident movement.
- Weight Distribution: Lean slightly forward and allow the crutch to bear a portion of your weight. The ergonomic grip and forearm support are designed to distribute pressure comfortably.
- Ambidextrous Use: The crutch can be used on either the left or right side, depending on your support needs. For general support, use the crutch on the side opposite your affected leg.

4. Maintenance and Care
To ensure the longevity and safe operation of your KMINA Quad Crutch, regular maintenance is recommended:
- Cleaning: Wipe down the crutch regularly with a damp cloth and mild soap. Avoid abrasive cleaners or solvents that could damage the finish or materials.
- Inspection: Periodically check all components for signs of wear, damage, or looseness. Pay close attention to the rubber tips on the 4-prong base, the height adjustment mechanism, and the forearm cuff.
- Storage: Store the crutch in a dry place away from extreme temperatures.

5. Troubleshooting
If you encounter any issues with your KMINA Quad Crutch, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Crutch feels unstable or wobbly. | Height not properly locked; worn rubber tips on base. | Ensure height adjustment button is fully engaged. Inspect and replace worn rubber tips if necessary. |
| Discomfort in wrist or forearm. | Incorrect height adjustment; improper grip. | Re-adjust crutch height as per "Setup and Assembly" section. Ensure your grip is firm but relaxed, and your forearm is properly seated in the cuff. |
| Difficulty moving the crutch. | Crutch too heavy for user's upper body strength. | This crutch is designed for users with moderate to high upper body strength due to its sturdy construction. If persistent difficulty occurs, consult a healthcare professional for alternative mobility aids. |
