Setup, Compatibility & Care
To install, ensure your grass trimmer is powered off and the spark plug wire is disconnected. Remove the existing trimmer head assembly, clean the drive shaft, and place the Dapetz blade onto the spindle, ensuring it sits flat against the drive washer. Secure it firmly with the supplied locking nut, rotating it counter-clockwise (or as specified by your trimmer manual) to tighten. The blade is compatible with many models from Makita, Bosch, and Stihl. To maintain the blade, periodically check for signs of bending or stress fractures. Clean away sap and grass buildup after every use, and touch up the ground edges with a flat file if they become dull to maintain peak cutting efficiency.
