Step to use a coconut scraper: For electric coconut scraper: Plugin your coconut scraper and push the vacuum button.  Place plate under the blade to collect scraped coconut. Start your grater and hold the coconut in front of the blade. You can change speed according to your need. Also, do not forget to change the coconut position. Otherwise, it will scrape the coconut shell. This mistake can damage the cutter. For manual coconut scraper: Place coconut scraper over a flat and clean surface. Apply pressure over it and push the knob with force to fix the position. Place plate under the blade for coconut collection. Hold coconut in front of the blade and rotate the handle to scrape it. Change the coconut position from time to time to avoid any damage.
