Operating
Loading Tissue Rolls
To load or replace the jumbo bath tissue rolls:

- Insert Rolls: Place two 9-inch jumbo bath tissue rolls onto the internal spindles. Ensure the paper unwinds from the bottom of each roll.
- Close and Lock: Close the front cover securely until it latches. Turn the key to lock the dispenser.

Maintenance
Cleaning and Care
To ensure the longevity and hygienic operation of your dispenser, follow these maintenance guidelines:
- Exterior Cleaning: Regularly wipe down the exterior surfaces of the dispenser with a mild, non-abrasive cleaner and a soft, damp cloth. Avoid using harsh chemicals, abrasive pads, or solvents, as these can damage the plastic finish.
- Interior Inspection: Periodically open the dispenser and inspect the interior for any dust, debris, or paper fragments that may accumulate. Remove any obstructions to ensure smooth operation.
- Mechanism Check: Verify that the internal slider mechanism moves freely and without resistance. Ensure the spindles for the tissue rolls are clean and allow rolls to rotate smoothly.
- Lock Functionality: Ensure the lock mechanism operates correctly. If it becomes stiff, a small amount of graphite lubricant can be applied to the keyhole.
- Damage Assessment: Inspect the dispenser for any signs of damage, such as cracks or broken parts. Replace damaged components promptly to maintain functionality and appearance.
Troubleshooting
Common Issues and Solutions
| Issue | Solution |
|---|---|
| Paper does not dispense smoothly. | Check for obstructions inside the dispenser. Ensure the tissue rolls are properly seated on the spindles and are not jammed. Verify that the paper is feeding from the bottom of the roll. |
| Dispenser cover does not close or lock. | Ensure no part of the tissue roll or any debris is obstructing the closing mechanism. Check if the key mechanism is clean and functional. |
| Second roll is accessible before the first is empty. | Inspect the slider mechanism for damage or obstruction. Ensure the first roll is fully depleted before expecting the slider to shift to the second roll. |
| Dispenser is loose on the wall. | Tighten mounting screws. If the wall anchors are stripped, consider relocating the dispenser or using new, more robust anchors. |
