Hi All,
My stihl HSA 86 battery hedgetrimmer has packed in, back up petrol has lost a tooth, so bought a used HS82 Rc as it has a wide tooth gap for heavy stuff (so it is something I may use after getting battery one repaired after lockdown). Bought off e bay so a gamble, got it For £189 with delivery and started up third or 4th pull, runs well with no visible signs of bad smoke. Blades are ok, I have tried sharpening some before with a file and whetstone but not much difference despite feeling sharp on the finger.
Any ideas what I should pay to get them sharpened at a stihl dealers compared to a new set of blades, It cuts decent but thinking longer term.
It is a 24 inch blade, does anyone know if the 30 inch fits on the same machine, I woud think not but am not sure.
I know this machine is for heavy cutting and certainly not topiary but my mate has one and he says it still gices a lovely clean cut.

i use a small angle grinder to sharpen my blades. its quick, does a good job, and its free.
Hand sharpening with a good file or a drum sander on a dremel works very well and should give a sharp cutting edge, are you deburring the flat under side of the blade when you have sharpened them as this makes a hell of a difference when cutting.
Yes Dave, I use a small whetstont i have on the flat side. maybe I wasnt filing on the right angle and it was a cheapish but good mountfield trimmer, maybe once the blades were worn they dont sharpen very good, I worked in engineering for a long time and never had much success with sharpening things.
What has happened to the HSA86? I have one and find it to be really good.
Why not just replace the HSA 86 [24 inch model - £275 less 12% discount = £242] as you already have the batteries and charger?
Always use a hand file to sharpen blades. You only need two or three strokes to sharpen. Grinders will take off too much metal and therefore shorten the life of the blades. Stihl say to use a hand file too. A whet stone to de-burr the underside [flat side] after filing is a must.
You should be able to buy and fit the longer blade set. I have done this myself although not on your particular model.
Hi Vic,
I posted about the HSA 86 in the forum earlier, It started to take a couple of seconds to get up to full speed/power and now even longer and after a couple of minutes the lights come on the battery which states the machine is overheating.
I grease it little and often clearing out as much old grease and debris as I can.I always spray the blades before and after use as well. I have hardly used it and is a little over a year old, I have the longreach cordless as well which is excellent.
Rather than buy another HSA86 which would leave me with 2 of the same tools I thought buying the bigger petrol one would help when coming to bigger hedge reduction jobs.
Also my confidence has now dropped in the battery tools,I used to look at them as toys but then plumped for the long reach. was impressed. and thus bought the 86 but this has hardly done any work at all and only on that years growth. so until my dealer opens and I find out whats wrong I wouldnt go for another.
2 long reaches, 3 mowers, 2 strimmers, 2 chainsaws, 4 hedgetrimmers, (2 working, 1 with a tooth missing) a boat load of power tools, table saws etc. No wonder I cannot find anything in my garage.
3 solid red lights on the battery indicate overheating. 3 flashing red lights mean a fault in the tool. 4 flashing lights indicate a battery problem. I suspect it needs a new controller
Have you phoned your dealer? Although the shop is closed with the shutters down, my dealer is still open in the ‘back shop’ as it were and is taking phone calls for spares orders, so your dealer might still be available to troubleshoot and remedy your problems with the HSA 86.
I e mailed them Vic and all the fitters/mechanics are off so cannot help.
Have you tried loosening the blade bolts and running it?
my long reach did the same thing after winter last year when it had been sat for about 2 months
.
like you I spray blades after use but this was gummed up still. I ran it loose and sprayed oil when running and tightened bolts and was fine afterwards
No Richard, I might give that a go later if I get time.
