Just looked at my multitool yesterday & discovered it is indeed a Clarke 240 volt jobby so it must have come from Machine Mark not as I initially said ......Screw Fix.
I have four of the Bosch PMF180s I mentioned... three of them have needed the motors repairing, including the one I bought brand new
Two of the faulty ones were ebay spots, there was another which I won for £6 but the seller refused to send it as it would have cost him more in postage - he'd put free post in the deal
I think in my user instruction sheets , it says seven minutes maximum continuous use , then a minutes free running to cool the machine down.
Also watch out that you don't cover the vents in & out with your hands whilst using them .... found an inch by 1& 1/4 inch strip of silver duct tape stuck on the air out vents when I use the machine this afternoon .. I felt it getting warm .... luckily found it in time .
