Where to purchase a M8

[Mark 5]

The physical size of trimmer heads usually goes by the cc of the engine. So if your engine is 52cc you look for a head that's suitable for up to 52cc.

And don't be tempted to fill it with heavier line. My head will take 3mm line but the trimmer isn't fit to spin it fast enough when filled with 3mm and it doesn't cut very well. But fill it with 2.4 line and the engine can rev out fully & it shaves the grass no bother.

Thanks, my strimmer is 240v electric, see post 4.

I take your point about line, my strimmer head came pre-wound with 2.4 twisted.

From the get go, line being twisted, it was getting caught on its self inside the head and would constantly snap.

I purchased a small coil of 2.4mm Oregon round, ( yellow ), much, much better, so will stick to that and hopefully this will lessen the constant stop, unjam and go issues I was having.

I'm not knocking twisted line but my strimmer head was not copping, ( I had some 2mm twisted, changed to that, same issue ), with it well, not helped by the fact the existing strimmer head spool inside is not a great design, it's why I'm on the hunt for a better head altogether.

When you say, jams the spool, what do you mean?
With the Stihl strimmers we were using their line, some were good, the yellow one, but others (red coloured) would constantly overheat and melt together and was a pain to sort out.

The dealer apparently told them to soak the line in water overnight, being nylon it will absorb a fair amount, and may stop it melting together.

See above but take your point on soaking line.
