How to Use Ryobi BC30 Attachments on a Craftsman

The Ryobi BC30 is a brush-cutter tool attachment meant to cut through thick weeds and hard-to-remove stalk. While the BC30 is designed to be used with the Ryobi brush-cutter trimmer, the attachment will also fit onto other brand-name trimmers, including Craftsman. Attaching the tool onto the Craftsman is fairly simple to do -- but remember that using a different brand of attachment may void the warranty on the Craftsman or Ryobi unit if something goes wrong.

Instructions

- 1
  Loosen the knob on the Craftsman trimmer head by turning it counterclockwise. Push the button in while turning and pulling to separate and remove the ends of the power-tool head.
- 2
  Remove the string-head assembly from the tool, and remove the cutting-attachment shield by removing the three screws from the bottom of the cutting-attachment shield.
- 3
  Line up the shaft-brushing hole with the locking-rod hole, and place the Craftsman locking rod into the hole. Hold the locking rod in place with one hand, and turn the blade lock nut with a 5/8-inch socket wrench, clockwise with your other hand.
- 4
  Slide out the lock nut as well as the blade and blade retainer.
- 5
  Set the Ryobi blade-attachment retainer on the Craftsman output shaft, with the flat side on the bottom. Turn in a counterclockwise direction to settle the retainer into position until secure.
- 6
  Take off the locking rod and slide the Ryobi blade attachment onto the retainer -- and connect the three hex-head screws on the bottom, using a hex-head screwdriver, in a clockwise direction until secure.
- 7
  Tighten the screws with a hex-head screwdriver in a clockwise direction, and increase the torque on the Craftsman to 40 or 50 inches per pound, at a minimum, for proper use.
