Here is a guide on how to perform maintenance on your pro-spin mini.
Here is what you will need:
- flat head screw driver
- 3 in 1 oil or similar
- a tooth brush
- warm soapy water
using the flat head screw driver to carefully pop off the red bearing dust cap (see pic).
grab your tooth brush and warm soapy water and scrub the visible ball bearings, rinse thoroughly with hot water giving it a spin while you rinse
allow to fully dry
add 1 drop of oil to the bearing, adding just 1 drop of oil is enough to prevent over spinning while not adding a source of friction, refit dust cover.
