Please store in dry and well ventilated premises without major temperature changes (temperatures between 10 and 30 C and max. 70% relative humidity). This will help preserve the physical properties of the reinforced resin bonded grinding wheels for up to three years, and up to two years for non-reinforced ones. The storage premises should be as close to the place of use as possible in order to avoid mechanical damage to the wheels during transport, as well as moisture condensation while in transit on colder days. Please use appropriate stands, shelves, drawers and boxes for storing various types of grinding wheels.
