[. . . ] Before using this stand we urge you to read this Owner's Manual thoroughly, and keep it in a safe place for later reference. [. . . ] Doing so may result in overturning of the stand and instrument causing serious injury. Before moving the stand, release the caster brakes and move the stand gently. Once the playing position of the stand has been determined, engage the caster brakes. The glockenspiel stand consists of a tabletop supported by legs that are attached to large casters (100mm diameter). The stand allows easy transport of the glockenspiel across flat surfaces and the tabletop is large enough to support any of the Yamaha glockenspiels, including older model types such as the YG1000/250C/50C or the Deagan Orchestra Bells 1590. Adjustable legs with grooves provide solid support of the instrument during performance or transport. [. . . ] Do not touch the notched part during height adjustment to avoid injury. [. . . ]
