To reduce the risk of cutting the cord while you're mowing, start mowing in the area nearest the electrical outlet, then mow away from the outlet so the power cord will be behind you. Make sure all safety guards are in place and keep the mower's blades sharp. If you do hit a foreign object or have a mower malfunction, remember to turn off the mower and disconnect the power cord before inspecting for damage. Keep your hands and feet away from mower's blades. Never reach under the mower for any reason while the mower is in operation and make all adjustments with the motor off.
Safe footwear is important, especially with walk-behind mowers.
Make sure your shoes provide good traction to reduce slipping and have sturdy soles to resist punctures. Never work barefoot or in sandals, canvas shoes, etc. Never leave a lawn mower operational while unattended. Curious children, eager to help out, may get seriously injured. Before using any appliance or tool, read and follow the manufacturer's use and care instructions that come with the product.
