Read this Section of the manual thor- oughly before you start the engine. Then, take the time to familiarize yourself with the basic operation of the tiller before using it in the garden. Find an open, level area and practice using the tiller controls without the tines engaging the soil (put tines in “travel” setting). Only after you’ve become completely familiar with the tiller should you begin using it in the garden.
