How to Change Strimmer Wire on a 52cc Strimmer Bump Spool

To remove the spool, place your provided hex key through the black protective cup in the spool.

Spin the spool clockwise until it comes away from the shaft.

Push the push button down with your thumb and twist off the top.

Twist the spool out of the casing. You should have a spring and two washers inside.

Fold the strimming wire in half. Place the line over the spool, with one side of line in each half. Wrap both halves all the way round the spool. Bring the line through the loop.

Pull the line tight and hook the knot into the slot in spool. Now wrap the strimmer line around the spool, being careful to have each half of the line in the appropriate half of the spool.

Pull the ends of the line out of the two oval slots in the spool. Replace both washers and the spring in the spool base.

Push the spool back into the base, onto the spring. Be sure to line up the 3 teeth with the 3 notches.

Bend both ends of the strimming wire into right angles. Thread each line end into the hole in the spool base.

Push the spool down into the base

Line up the top with the base. Push down and twist. Your spool should now be back together!
