How to fix a MIRKA CEROS Sander with no power supply LED light?
If there is no light from the power supply LED when switched on, it could be due to: * The power cord is not properly attached to the power supply unit or the AC socket. Connect it properly. * A broken fuse. Replace the fuse; a spare fuse is included inside the fuse holder.
Why does the LED on my MIRKA Sander turn red when sanding?
If the LED on both the power supply and the MIRKA sander turns red while sanding, it indicates too heavy long-term load. To resolve this, use a lighter load, switch off the power, wait 5 seconds, and then switch it on again.
What to do if the MIRKA CEROS LED is red and the sander slows down?
If the sander LED is red and the MIRKA sander slows down to 4,000 RPM while sanding, it means the temperature is too high due to a too heavy long-term load. Reduce the load on the sander for some time, and the sander will speed up again.
