When working with your professional Hawaiian shaved ice machine, you must maintain the quality of that fresh fluffy snow that your customers are accustomed to. Routinely replacing your blade is a vital part of keeping that machine operating at its best. We encourage you to change the blade on the HC-8E every 2,000 to 4,000 servings. This keeps the consistency of your product so customers will always return for more! This blade is easy to replace by simply grabbing that handy screw driver and releasing the two screws. Replace the blade and tighten the screws and you’ll be ready to roll. As always, if you have questions about changing your blade, feel free to give us a buzz and we’ll gladly walk you through the process. We can be reached at 1-800-620-2869.
