GENERAL SAFETY RULES  Stop the engine and allow to cool before refueling or storing the unit.  Allow the engine to cool; empty the fuel tank and secure the unit from moving before transporting in a vehicle.  Wear your protective equipment and observe all safety instructions. For units equipped with a clutch, be sure the cutting attachment stops turning when the engine idles. When the unit is turned off make sure the cutting attachment has stopped before the unit is set down. SPECIFIC SAFETY RULES  Inspect before use. Replace damaged parts. Make sure fasteners are in place and secure. Check for fuel leaks.  Replace string head if cracked, chipped, or damaged in any way. Be sure the string head is properly installed and securely fastened. Failure to do so can cause serious injury.  Make sure all guards, straps, deflectors, and handles are properly and securely attached.  Use only the manufacturer's replacement string in the cutting head. Do not use any other cutting attachment. To install any other brand of replacement string or cutting head to this string trimmer can result in serious personal injury. Never use, for example, wire or wire-rope, which can break off and become a dangerous projectile.  Never operate unit without the grass deflector in place and in good condition.  Maintain a firm grip on both handles while trimming. Keep string head below waist level. Never cut with the string head located over 30 in. or more above the ground.  Do not place battery tools or their batteries near fire or heat. This will reduce the risk of explosion and possibly injury.  Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least 30 ft. from refueling site before starting engine. Wipe up any fuel spillage. Do not smoke! Failure to heed this warning could result in serious personal injury.  Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has been dropped or received a sharp blow. A damaged battery is subject to explosion. Properly dispose of a dropped or damaged battery immediately.  Batteries can explode in the presence of a source of ignition, such as a pilot light. To reduce the risk of serious personal injury, never use any cordless product in the presence of open flame. An exploded battery can propel debris and chemicals. If exposed, flush with water immediately.  Do not charge battery tool in a damp or wet location. Following this rule will reduce the risk of electric shock.  For best results, your battery tool should be charged in a location where the temperature is more than 50°F but less than 100°F. To reduce the risk of serious personal injury, do not store outside or in vehicles.  Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and water, then neutralize with lemon juice or vinegar. If liquid gets into your eyes, flush them with clean water for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce the risk of serious personal injury. 4 - English
