Using the M6 Series pneumatic tools is easy. First, before you start, make sure the air line has automatic filtering and lubrication, and the compressed air is clean. Connect it with a proper hose. When operating, wear safety glasses and hearing protection. Hold the tool right, start the cutters, and then use it on the surface. Move it forward and backward gently. Don't push too hard. If you need to adjust the depth because the cutters are worn, just follow the steps: loosen the screw, move the depth shoe, and then tighten the screw. When it's time to replace the cutter bundle, install the pins and washers, take off the old bundle, put on the new one, and install the pins and washers again. Keep these steps in mind for a smooth and safe operation.
