Using this Behringer KS1002 keyboard stand is easy. First, unfold the double X brace and set it up on a flat surface. Place your keyboard on the stand, making sure it sits securely on the shock - absorbing rubber sleeves. Adjust the height and width to your preference using the quick - release locking pin. You can adjust it within the range of 20' H x 34' W (50 cm x 87 cm) up to 38' H x 18' W (92 cm x 46 cm). When you're done using it, fold it up for easy storage and transport. As a note, don't use this stand for long - term support of instruments with a nitrocellulose lacquer finish. To maintain it, clean the stand regularly with a soft, dry cloth. Check the rubber sleeves and locking pin from time to time to ensure they're in good condition.
