@Norton posted:It would be a good idea to remove the top every few years and blow the dust out. Depending on your environment and operating hours they can build a lot. There are 7 screws that have to be removed at the bottom to do that. You need a long 3mm allen wrench to remove them.

Perfect thanks. I haven’t opened it since I bought it around 2000. So I’m sure there’s plenty of dust to get out. 💨 The handle is starting to feel loose and I’ll replace the fan. Then cross my fingers. 🤞
