Hi. I have been loving my electric saw since the day I bought it. I waited till the battery technology was right to pull the trigger and had an awakening since it became my go to climbing saw. Then…maybe it got slightly wet when using it in some rain last week but I had used it fine since then. Maybe I carry it in the hot passenger footwell of my truck and even take it on vacation in the back of the family car because no gas and I use canola bar oil. But I got to the top of a maple I was removing and turned it on and it would not run. Power light on and full battery but no throttle response. If I held down the trigger the red triangle flashed. Chain brake was off and I could spin the chain smoothly by hand. Reseated battery several times till I did what I could with my silky and tried the other battery to no avail, later climbed back up begrudgingly with my 201t.
Got home and checked the forums and blew out the casing with compressed air. Tried both batteries again. Left it sitting on the work bench and worked on other things. After ten minutes or so, heard a sizzling noise and made a jab to pull the battery out but by the time I picked it up the saw let out an explosion like a bomb or an engine backfire. My ears were ringing for several hours. Long story shorter, the blast came from the left side cover vents and no outward sign of damage. It smoked for a while. The saw was not turned on. I pulled the battery and it was cool and unaffected and has since worked normal in the string trimmer.
It was kind of a surreal day because we soon we had a derecho wind come through and uproot a bunch of trees around but I can’t stop thinking about first, not having this saw to use anymore, and what could have happened if it was inside the cab with me or up in a tree hanging on my butt cheek or being held in use above shoulder height. I had heard about plenty of liion batteries exploding but something must also be amiss inside the saw case.
Can’t find any other reports of 540i fails so just wanted to put this out to other arborists to be aware of this possibility when using and storing said saw. I’ve tried to contact husqvarna about a different saw issue and can’t any response from a human so excited to post it here for some feedback.
