Using the Abaco Mortar Mixer M2 is easy. First, add the materials like sand, cement, and stone into the mixer. Then turn it on and let it do its job until you get a well - mixed result. When using, make sure the area is clear to avoid any obstacles. Also, don't overload the mixer with too many materials at once. For maintenance, clean the mixer after each use. Check the wheels regularly to ensure they're in good condition. Store it in a dry place when not in use to prevent rust.
