Put a screwdriver through the hole on the shaft and turn the head till the screwdriver drops through which holds the head so you can then undo / tighten

fuel mix ratio for fs/55 brushcutter?
3 answers
50:1
Hi bm, the mixture ratios depend on the quality of the 2-stroke oil. Good quality oil only needs 50:1 mix and the crappy cheap stuff to do the same job requires 25:1 approx. Of course you can vary those ratios a bit to suit . I use about 30:1 approx of good oil.New designs of cutters and chainsaws rely on speed rather than torque so the new oils are thinner especially chainbar oil so the less friction the better so higher speeds. You will notice if the line you use in the brushcutter is just a little bit too thick that it slows the rotation of the FS55. Recommended thickness is the best.Don't think thicker line is stronger and hence better. Personally for the amount of times the average joe uses these machines it's best to get the BEST OIL.
Stihl has recommendations that come with the manual. They have their own brand of oil and it's overpriced as you would expect. However, as Martin said, the average punter doesnt use their machine a lot - and I'm one of those - so I use the approved oil at the approved mix ratio.
One tip for the average punter is that the diaphragms in the carbie can get tired sitting around waiting for you to use the brushcutter. You can get overhaul kits from the dealer at a massive cost or get them on ebay cheaper - but beware that Stihl like to have their own special models for the carbies. If the diaphragms go soft or leaky then the engine doesnt want to idle etc etc. I replaced mine and the whole world improved.
