I have a Powercraft 600w multifunction saw new only used to cut foam unfortunately the small metal knob part that holds the blade broke so now the blade won't stay in place. Tried replacing v sm screw however it fell out v vibration of the blade. Any idea or help? Could I solder the screw in so I could use this to hold the blades through the sm hole on the blades? Model PCMFS/08
The soldering fix is a non-starter. The problem with low cost store own brand "pile 'em high and sell 'em cheap" stuff is that there's next to zero support. You MIGHT strike lucky at www.solenttools.co.uk but I wouldn't hold me breath.
I have been seriously impressed by the spares coverage of Eindhell tools. You do have to dig for the info but it looks like everything is available. Just be sure you record the model number, item code and serial number. They were also sold under the Ozito brand through Homebase when it was briefly run by Bunnings.
