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).
