Frequently asked questions

To extend the cutting line, gently bump the spool housing on a firm surface while the trimmer is running. This will release additional cutting line. If no line is released, bump the head more sharply or try a firmer surface.

To replace the spool, first disconnect the trimmer from the power supply. Then, press the release tabs on the spool head cover and remove it. Lift the spool out of the spool housing. Install a new pre-wound spool.

To adjust the telescoping boom, first disconnect the trimmer from the power supply. Then, unscrew the telescoping boom coupler and slide it to the desired position. Tighten the coupler.
