Edge preparation
Edge preparation includes the following working steps:
1.examination of the tread
2.treatment of the edges bottop surface
3.treatment of the side edges
4.edge finishing
5.edge repair

1.examination of the tread
From time to time, the treads should be controlled with a straightedge. The following pictures may occur:
concave tread: base is hollow on the inside, ski / board lies on edges, thus turns poorly and obtains the tendency to cut away.

2.treatment of the edges´ buttom surface (hanging cut)
Edges of ski or board should be cut in their front and back by a hanging cut to the outside. This enormeously improves turning properties.

Plane tread: tread forms a plane from one edge to the other, ski / board lies on base and edge and is – with corresponding edge tuning – good to control as well as it is easy to turn.
Should your ski / board not be plane, we recommend you to have it plane-cut at some qualified ski service.

Convex tread: base is arched to the outside, edges have bad support, ski board is hard to control.

3.treatment of the side edges (back-cut)
Before the side edge can be cut, the side cheek of the new ski must be scraped with sideMaxx. With side edge grinding tools the edges receive a precise back-cut.
Depending on the discipline and skill, the angle may vary (downhill, SuperG, 88-87°, special slalom 88-86°).
In order to precisely back-cut the side edge, profile edge grinding tools (Aluminium angle (20580)) are to be used.

4.edge finishing
Edges on the front and back of the ski / board, that do not influence gliding properties (the part of the edges, that has no contact to the trails during straight position of the ski) should be rounded.
New cut edges and extremly sharp edges at the back and front end of the ski / board reduce the turning properties and may easily result in driving mistakes. Therefore, the edges at the front and back areaare lightly defused at a length of 5 to 15 cm (edge grinding rubber). The edge grip is preserved and the ski / board keeps its turning properies.

5.edge repair
Due to stones on the trails, hardening of the edges may occur, since the contact between edge and stone temporarely causes great heat. Thus, the edge´s surface changes and becomes harder than the surrounding material. Those parts can hardly be removed with regular files and result in inexact work. After skiing, ridges and hardenings should be removed with the oxide stone before the edge is being cut again. Hereby, regular files would become blunt. Rework with the diamond file (coarse 360 or 800).
Tips for the outside: right next to the trails, edge ridges can be repaired with the EdgeTrick, affording no greater effort.
