If like me you have a stihl FSA 70R strimmer, be aware that this line is inferior to that originally supplied with your Autocut 12-2 head. That was a 2.4mm carbon fibre line and this line does not perform as well for tough work. GMD don’t tell you that. T
Garden Machinery Direct –
We’re sorry to hear this line didn’t meet your expectations. The line you purchased is genuine STIHL trimmer line and is fully compatible with the AutoCut 12-2 head. Performance can vary depending on the type of line and the conditions you’re cutting in, but there shouldn’t be any difference in suitability compared to the line originally supplied with the machine. If you believe there’s an issue with the product you’ve received, please get in touch with our team and we’ll be happy to help.

Does the job but is inclined to becoming tangled on the spool, no matter how careful I am with the single tap line feed.
