Edge Tuning - Base-side Preperation
If the running surface of the ski/snowboard is too concave (hollow) or too convex (rounded), it is almost impossible to use the ski/snowboard. In such cases, it is worth taking the ski/snowboard to your ski shop, where the surface can be professionally ground for you.
Today´s slopes are often extremely hard and icy (artificial snow slopes), which is why edge preparation is gaining increasing significance (carving skis, snowboards). The following procedure applies to daily manual preparation.
1) Pre-file
Remove ridges and areas of hardness (caused by stones) with diamond file blue or Universal Edge Grinder.
2) Check with the Straight Edge
Use the straight edge to check the evenness of the base and the edge offset.
3) Hang edge
If the edges of the ski are not filed sufficiently on the base side degree (ski turns badly or is heavy to turn), the Mulit Base File Control is used to file the hanging edge to 0.5° or 1.0°. Use the Prisma straight edge to check the angle.
