Using these Makita drywall cut-out saw blades is easy. First, make sure you have the Makita 18V LXT® Lithium - Ion Cordless Cut - Out Saw (XDS01Z). Insert the blade into the saw according to the saw's instructions. When making cuts, use the depth markings on the blade to get the right depth for your drywall. These blades can cut drywall up to 1 - 3/16” thick. For safety, always wear appropriate protective gear like goggles and gloves. When not in use, store the blades in a dry place to prevent rusting. Avoid using the blades on materials other than drywall as it may damage the blades. Regularly check the blades for any signs of wear or damage. If you notice any issues, replace the blade for continued safe and effective use.
