Grasski needs regular maintenance. This is key fact that you need to know before purchasing. How much maintenance is needed you will find out in following article.
But before we start, I would like to explain names and terms we use for grasski parts.
- Element or trolley
- Plate (serving as edge)
- Belt (connecting elements/trolleys on rail)
- Wood with alu layer
- Binding plate
- Binding supporting U
- Binding front (this one from race ski)
- Binding back (from race ski)
- Gliding insert
Grasski elements/trolleys needs careful and constant maintenance starting from the lubrication of the rolls. Lubrication is performed on each individual wheel using a manual pressure oiler every time the grasski are used: this is to minimize wear (thus extending the life of the grasski) and increase smoothness. This operation must be repeated several times throughout the day depending on the frequency of use of the tools.
For the lubrication of the trolley we use biodegradable oils that are easy to wash and non-polluting (in consideration of the fact that we use the tracks in nature) as bio and emulsifiable oils.biohydraulic oils with viscosity 46.
Without regular oiling rolls inside ski may get burned and damaged into such a level that ski speed will be lost. Solution to such damage is replace of all rolls (investment of 25€ - 50€ depending on speed of rolls) and often also gliding inserts.
Grass skis suffer, unlike the winter ski, from dust, gravel and sand. When skiing, especially with aggressive edging or crashing, dust and grass can get into rolls and slow ski. Therefore, if you want to get the maximum out of your skis, skis needs to be washed regularly. To do this you need a bucket, detergent, sponge and water.
First, pour the water into a bucket and add detergent. Then gradually wash one ski and another. Washing is done such a way so at first wash all with sponge to wash away dirt and then you start cranking ski in the water. Than rotate ski inside basket with water forward and backward fast enough to get as much dirt and mud and grass out from ski.
After first washing is done, put clean water inside basket and rotate ski inside water to clean grasski and rolls from detergents.
After washing is done, several times rotate ski in hand to get water out from ski. Final step is letting ski dry. Drying can be done in two ways. If you feel that belt is too tight, never let your ski dry on direct sun! On other hand, if you feel belt is very loose, put wet ski on direct sun to let them dry quicker....this will make belt shrink a little.
