This is what the cut looks like after it's been stomped down: Note: The sample cut shown is only 18" long with a 24" length of 1" poly pipe stuffed inside as an illustration to show how easy the cut is to make, how nicely the pipe fits, and how little impact there is to the grass after the cut is sealed - you can hardly see it. Lay the wire at least 2 m/6.5 ft (for Aspire™ R4: 1 m/3.3 ft) in front of the charging station in a straight line. Use pegs to attach the wire to the ground all the way up to the planned point for connecting to the boundary wire. Cut the boundary wire using a pair of wire cutters at the connection point with the boundary wire. A brush cutter, also known as a strimmer, line trimmer, weed whacker, weed whip, weed eater, weedy, or whipper snipper, is a powered handheld device that use Lock the shaft with a lock pin or Allen key. To replace a wire: fit the new grass trimmer head and tighten it while the shaft is locked. To replace a metal cutting tool: place the metal blade onto the thrust plate, fit the thrust washer and rider plate onto the shaft, and tighten the nut. Remove the tool and release the locked shaft. Remove the spool cap and old spool and cut approximately 20 feet of the replacement string. On the upper part of the spool, insert approximately 1/2 inch of one end of the trimmer line into one of the holes. Then, neatly wrap the string around the spool in the direction indicated by the arrows on the spool, leaving 4 inches unwrapped.
