Sorry Dominique,

Autoprop.....700-1000 hours or when the bearings feel rough, they need replacing, not that difficult, but some special tools can find the complete instructions online Autoprop service.
Otherwise, grease the bearings of the  three blades through the removable screws,( you need a special grease nipple), every time you haul out...
