Using the MTA Heavy Duty Vacuum Lifter Series is quite straightforward. First, choose the right model based on your material's weight and surface characteristics. For corded models, simply plug it into a suitable electrical outlet. Battery - powered models need to be fully charged before use, and air - powered ones should be connected to an appropriate air source. When lifting, make sure the vacuum pads are firmly placed on the material's surface. Keep in mind that these are special - order products, so plan your purchase in advance. During use, avoid overloading the lifter beyond its specified capacity. For maintenance, regularly check the vacuum pads for any signs of wear or damage. Clean the pads and the lifter body after each use. Store the lifter in a dry and clean place to extend its lifespan.
