Wipe up any spills. Using a Ground Fault Interrupter circuit gives maximum safety protection. Clear the work area of potential safety hazards such as wire, stones, bottles, cans, sticks, etc. Be sure there are no children, pets, or bystanders in the working area. Do not use the tiller near underground utilities, irrigation pipes, trees, etc.
Deadly fumes can build up.
Keep hands and feet clear of all moving parts. Do not operate in wet or slippery conditions. This is especially important for electric models. Be sure the depth regulator is engaged before starting the tiller. Failing to do this could cause the machine to lurch quickly away from you.
