I hope someone can help, about 18 months agos i purchased the stihl long reach telescopic trimmer and was very impressed so bought the Hsa 86 last year as i already had 2 batteries and the charger, I was very impressed with this as well, however just after lockdown it has been slow to start, building up speed and power after a few seconds , I grease it little and often to the same amount as when bought.
Now after trying to run it for a minute 3 red lights come on which means tool is overheating and needs cooling, leave it an hour and same thing happens.
Interestingly it seems to run more powerful upside down until it cuts out, i definitely havent overfilled it with grease, it only cuts this years new growth , batteries stored in house and tool has stihl battery cover in place in garage.
I now have 3 batteries and its the same with all of them.
My back up is a petrol with a tooth missing so not ideal, dealers are closed so may have to buy a new pertol one until they reopen.I dont want to buy another HSA 86 until i find out what has went wrong with this one.
Any help is appreciated
