DANGER
Striking concrete or other hard materials with spinning edger blade can cause severe blade
damage or breakage, and serious or fatal injuries from flying fragments. Stop unit immediately
and check blade if an object is struck. Replace blade if broken, cracked, bent, chipped or
otherwise damaged, or if unit began shaking or vibrating after striking the object.
Small stones and other hard debris can be thrown from blade guard, and strike bystanders
and nearby buildings. Keep bystanders a minimum of 50 feet (15 m) away when operating
edger. Always keep flow of edging debris directed away from windows, parked vehicles,
buildings, and bystanders. Always operate edger with unit to right side of body only. Wear
eye protection, work gloves, and protective clothing. Use full face shield when edging in rocky
or debris-filled soil.
