Hazard Warnings

• ⚠️ WARNING: Read and follow all safety precautions in your trimmer's manual. Improper use can cause serious or fatal injury!
• Objects may be thrown or ricochet in all directions. To reduce risk of injury, never operate a trimmer without a properly configured and mounted deflector. Keep bystanders at least 15 m (50 ft.) away. (?↔️? 15m (50ft))
• To reduce risk of eye injury, always wear goggles or close-fitting protective glasses with adequate side protection that are impact-rated and marked as complying with ANSI Z87.1 (US), EN 166 (Europe) or your national standard. (?)
• To reduce the risk of hearing damage, wear sound barriers (ear plugs or ear muffs). (?)
• A cracked, damaged or worn out mowing head may shatter at high speeds and cause serious or fatal injury. To reduce risk of injury from broken parts, check condition of trimmer and mowing head before starting work and at regular short intervals thereafter.
• Some STIHL mowing heads have a metal core. High-speed contact with rock or other hard objects may create sparks, which can ignite flammable materials under certain circumstances. Flammable materials include dry vegetation and brush, particularly when weather conditions are hot and dry. When there is a risk of fire or wildfire, do not use a mowing head with a metal core around dry vegetation or brush.
• Keep mowing lines in a water bath between 12 hours and 24 hours before use to increase their useful life.
