Safety

Center pivots run on high voltage and heavy moving machinery. Shut off and lock out power at the main disconnect before you open a panel or touch anything electrical. If you are not sure, stop and call your local pivot dealer or a licensed electrician. These pages tell you what a code means. They do not replace a qualified technician, and the safety instructions that came with your equipment come first.
