Setup
Follow these steps to load a new roll of tape into your dispenser:
- Prepare the Tape Roll: Ensure your packing tape roll is 3 inches wide. Locate the end of the tape roll.
- Open Side Load Mechanism: The Uline H-596 features a side-load design. Gently pull the tape roll holder outwards from the main body of the dispenser.
- Load the Tape: Place the tape roll onto the tape roll holder with the adhesive side facing down (sticky side towards the handle). Ensure the tape unwinds from the bottom of the roll.
- Thread the Tape: Pull approximately 6-8 inches of tape off the roll. Guide the tape between the pressure roller and the metal plate, ensuring it passes under the cutting blade.
- Secure the Tape: Press the tape firmly against the pressure roller to ensure it adheres properly.
- Adjust Tension: Use the blue tension knob located on the side of the tape roll holder to adjust the desired tension. Turn clockwise to increase tension, counter-clockwise to decrease.

Operating Instructions
Using your Uline H-596 tape dispenser is straightforward:
- Start Application: Place the adhesive end of the tape onto the surface you wish to seal.
- Apply Tape: While holding the dispenser by the handle, roll the dispenser along the surface, applying even pressure. The pressure roller will ensure smooth and consistent tape application.
- Cut Tape: Once the desired length of tape is applied, tilt the dispenser downwards and press the cutting blade firmly against the tape to sever it. Ensure the tape is taut for a clean cut.
- Repeat: Lift the dispenser and prepare for the next application.

Maintenance
Regular maintenance will prolong the life and performance of your tape dispenser:
- Cleaning: Periodically wipe down the dispenser with a dry cloth to remove dust and tape residue. For stubborn adhesive, use a small amount of rubbing alcohol on a cloth, avoiding direct contact with the rubber roller.
- Blade Inspection: Inspect the cutting blade regularly for any damage or dullness. A dull blade can lead to uneven cuts.
- Roller Condition: Ensure the pressure roller is clean and free of debris to maintain smooth tape application.
- Storage: Store the dispenser in a clean, dry place away from extreme temperatures and direct sunlight.
Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tape not cutting cleanly | Dull blade, tape not taut, or residue on blade. | Clean the blade. Ensure tape is taut before cutting. Consider blade replacement if consistently dull. |
| Tape not dispensing smoothly | Incorrect tension, dirty pressure roller, or tape roll binding. | Adjust the tension knob. Clean the pressure roller. Ensure tape roll is properly seated and not damaged. |
| Tape falling off the dispenser | Tape not properly threaded or insufficient tension. | Re-thread the tape according to setup instructions. Increase tension using the tension knob. |
