Thank you Don.Yes I tried it without filters.No difference.I thought about a motor toc but it runs so little it would hardly overheat that quickly.Also it will start straight away again.Battery showing 24.7v.
Hmmmm sounds like the battery pack is up the creek. Had quite a few of these handhelds with similar problem. (Runs so long – cut off – release trigger – press trigger – works – cuts off – and so on)
Thank you Spiderpig. Have connected multimeter up to it and pressed switch. There was no drop in voltage when it shut down.Have taken a chance and ordered motor body.
