Improperly used Aero-Flex Line Blades can pose an increased risk of laceration and thrown object injuries. The most significant concerns involve body contact with rotating line blades and/or from thrown objects. Be especially careful to keep bystanders away!
	Read, understand, and follow these instructions and those from your trimmer.

Avoid permanent eye loss or injury. Always wear properly selected ANSI Z87 safety eye protection. Wear proper leg, body, face and hearing protection.

As a general rule, trim at part throttle or lower line blade tip speeds to reduce danger of thrown objects or debris. Heavier vegetation may require additional power and speed. Be very cautious! Direct debris away from yourself (stand to the side of the trimmer), other bystanders (even outside of a 50 foot distance), and away from personal property. Stop trimming operation immediately if pedestrians, vehicles, or animals move near your cutting location.

Do not remove debris shield from trimmer unit. Assure proper alignment. Keep the rotating line blades a safe distance away from feet and other body parts. Turn off the engine before servicing or changing out the line blades.

Be careful when entering the rotating line blades into any debris areas (for example, gravel drives or walkways), outdoor structures, property, or outdoor furniture as they can throw debris that will cut or damage an object!

Do not operate any trimmer in the vicinity of people or animals, with particular concern for thrown objects and harmful line blade contact. Keep cutting head below waist. Be aware that the trimmer head can move sideways or up suddenly. Control side thrust forces. Always use two hands on the handles of your trimmer. Do not wear ties, jewelry, or loose, dangling clothing that could get caught in unit. Do not operate this product under the influence of alcohol or drugs that could affect your vision, dexterity or judgment. Before cutting, remove rocks, broken glass, wire or other objects.

Choosing Line Blade Color Options

	We recommend using two orange and two yellow line blades. This creates a slight, helpful updraft.
	Never use one or three lines (causes imbalance). Two can be used if your engine has low power.
	Control Trimming at Slower Speeds Using Part Trigger: Faster Line Blade Speeds Accelerate Abrasion Wear Learn to use lower speed power cutting. Using 4 line blades at lower speeds will extend line blade life. The slower you go, the longer your line blade life. Ease off the throttle. It Pays!
	Use Visual Line Blade Plane - For Better Control The line blade (with proper light) creates a noticeable and visible cutting plane for your added control
	Vertical Edging Against Abrasives (concrete, bricks, asphalt, etc.) Use the helpful line blade's self-propelling thrust to help pull you along. Edge in directrions of thrust. The strong line blades make a powerful edging tool at lower speeds without stopping; they will save you time and money. It's even better to use shorter or more worn line blades. Forcing line blades hard against abrasive surfaces will accelerate the abrasion wear rate.
	Learning Options for Updraft for Clean Cuts and Downdraft for Blowing Away Debris Updraft rotary mowing: Two yellow and two orange line blades create slight, helpful updraft, like with a rotary mower that lifts longer grass to help cut it more cleanly. When blowing debris away: choose four of the proper color line blades with all for round sides (not the sharp) leading. Keep bystanders away! For clockwise rotation, use four yellow blades. For counterclockwise rotation, use four orange blades.
Control Direction and Speed of Debris Thrown by Trimmer WARNING AND CAUTION: Be sure to keep bystanders and animals well away (at least 50'). One side of your rotating swath will throw debris back toward you; the opposite side will propel debris away. Use part throttle to reduce the quantity and velocity of the propelled debris. Trimming Around Sensitive Objects (Use visible line blade plane for a helpful control) The powerful line blades can damage tree bark and sensitive vegetation. Operating a lower speeds will help control and avoid damage. Trimming Around Fences Avoid hitting fence. Control position by using the visible swath. Cut along the fence in the same direction of the pulling line blade thrust. Don't force line blades into the fence, or against their thrust forces. Avoid unnecessary heavy impacts. In Heavy Vegetation: How to reduce vegetation wrapping to head Use full throttle operation in heavy vegetation. Cutting long grass strands at their base will drop and then wrap around the head to cause head to bind. Start cutting at the top of the high strands. This will make shorter strands from wrapping. How to Reduce Engine Bogging and Stalling (Can occur with smaller, older direct drive trimmers) Control options to help reduce stalling: Don't hack or rapidly swing head into heavy vegetation Gently control entry into vegetation Try two vs. four line blades, or try shorter line blades (scissor trim about 1/2" off tip of line blades).

How to Moisturize and Store Your Line Blades Proper moisture retention is important for any nylon which requires internal moisture retention for strength and flexibility. If it dries out it will become brittle. Learn how to control the proper amount of moisture necessary for nylon. Important moisture retention in the line blades can be lost in dry climates or over long periods of storage. Humidity less than 50% is more likely an environment that will cause the line blades to dry out. How to assure adequate moisture: If any doubt of dryness (low local humidity or winter storage). Insert line blades into a zip lock plastic bag and fill halfway with water. Seal and let soak for 2-3 days. Pour out the water and reseal the wet lines in the zip lock bag. Store out of direct sunlight.
