• 3). Depress the trigger on the handle until it is at the full throttle position.
  
  
• 4). Pull the starter cord at least four times in quick succession. If the engine does not start up, pull four more times until the engine turns over.

Replacing Line

• 1). Unscrew the knob on the bottom of the trimmer and remove the spool, spring and housing. Remove any remaining cutter line so that the spool is empty.
  
  
• 2). Measure an 18-foot length of line of cutter line. Place one end into the two holes on the top of the spool and pull them through, making sure they are even in length.
  
  
• 3). Wrap the line around the spool in a clockwise fashion, making sure not to twist the lines. Leave about 5 inches of line at the ends. Lock the the line ends on the notches on both ends of the spool.
  
  
• 4). Place the spring on the center of the housing and then place the spool on top of the the spring inside the housing. Make sure to feed the lines through the holes on both ends of the housing.
  
  
• 5). Squeeze the spool in the housing to depress the internal spring. Pull both ends of the line so that they remove themselves from the spool notches. Place the spool back onto the trimmer post and screw the knob back on tightly to lock it into place.
