So Numatic’s Henry – the bombproof vacuum cleaner – or so we thought – until a few weeks ago the on/off switch started to play up – and poor Henry struggled to get sucking.
Now Henry’s been through some tough times – and by that I mean, well – bashed, dropped, banged, sat on and used as a scooter by my kids …
So off to eBay my better half went and ordered a replacement switch. Cost around a fiver delivered.
With much trepidation – once the switch had arrived – I started the task of replacement. But I was worried unduly – Henry turned out to be easy to service as the following steps will show.
So off comes Henry’s top half – and I placed it, his, top upside down on some newspaper.
Next up – undo all the screws.
Now lift the unscrewed section off – the screws can stay in the screw holes and safely place it to one side.
Here is Henry’s brain. And when I say brain, I just mean his on/off switch.
Now at this point things start to get a bit messy – there is black carbon everywhere – and this came off the brushes inside the electric motor. So don’t be doing this job in your Sunday best.
Gently remove the switch. And I’m not going to give you a warning to unplug the appliance before doing so. To be honest if you’re taking thing apart without unplugging them it’s a miracle you are still alive and even if I had said to unplug Henry before TAMPERING WITH HIS INNARDS THAT ARE COURSING WITH 240VOLTS AT 13AMPS would you have listened? No I didn’t think so.
Now this is the really really important bit. Pull the terminals off the old switch and put them onto the new switch. The terminals have to go in the same place as they came from off the old switch. If you get this wrong (a) There will be a big bang (b) There will be smoke and possibly fire (c) Hospital food will be on the menu for the foreseeable future.
Okay now the new switch is wired up it’s time to put it back into it’s little home.
The switch needs to be gently teased into place. Actually that’s not true – it took quite a lot of fiddling about with – but it went in okay in the end.
Assembly is the reverse is disassembly. Eg, put it all back together and do up the screws. Note Henry looking on – he can’t wait to get his new brain!
And that’s it – test of course … but if everything went to plan Henry is back up and running again. And just look at that little smile on his cute little face!
So all together this takes about 10 minutes to do.
Henry is low-tech, bomb proof and unlike some other vacuum cleaners – easy to work on. No instructions required.
A nation of school caretakers can’t be wrong.
Well done Henry. Well done Numatic.
Here’s to another 10 years of service.
