1. Open lid and detach the see through plastic portion (Release clip on underside near hinge)
2. Prise off the motor fan cover at the back (From the bottom with a flat screwdriver).
3.Loosen the base from it's small clips all the way around.
4.Turn unit upside down and work the base over the motor fan blades.
5. Once over the fan the base should free itself.
When re-assembling make sure you locate the front buttons so they are in the right position first. Then press & pull the base back over the motor fan.
At this point you may need to work the base a little bit to get it correctly aligned with its clips then press down firmly and it should re-seat itself with a click. Put the screws back in and click the motor cover back into place to finish.
