My Black & Decker GT 230 hedge trimmer (about 8 years old) has started playing up. It's never previously complained about cutting thicker stems, but recently, if anything beyond the most slender stems catches in the teeth, it causes the motor to disengage from the cutting blade, and race, - it's as though a clutch is slipping.
Can I fix this myself? Is it a job for a service centre, or will that cost (almost) as much as a replacement?
