Introducing the Jeessee 2" x 1" Aluminum Oxide Flap Wheel with 1/4" Shank Mounted, a versatile sanding tool designed for optimal performance. Here are some important tips to ensure the best results: To enhance performance, soak the gauze in 40°-60°C water for 2-3 minutes before use. This increases toughness, extends the service life by 30%, reduces processing dust, and prevents fragmentation. During installation, pay attention to the direction of the blades to avoid any operational issues. Install the blades with a slight inclination from the outside to the inside, aligning with the rotation direction of the device. Before starting your work, run the flap wheel idling for 1 minute and ensure the rotating head of the electric grinder is correctly installed in the designated direction. Prioritize safety by wearing a mask and protective glasses during operation to prevent debris from entering your eyes, mouth, and nose. Experience enhanced performance, extended service life, and improved safety with the Jeessee 2" x 1" Aluminum Oxide Flap Wheel. Elevate your sanding projects with confidence and efficiency.
