Assembly Cautions • When assembling/disassembling the instrument, do so with at least two persons and follow the instructions outlined in this manual. Assembly in the wrong order can cause the pipes to drop which may result in an injury, impair the performance functionality of the instrument or cause noise. € After final adjustment of the legs the fixing screws must be tightened securely to prevent loosening.
