This document is the instruction manual for Yamaha 900 Series Hi-Hat Stand.
This document serves as an owner's guide for the Yamaha HS740A and HS840 hi-hat stands. It covers essential safety precautions, such as tightening securing bolts to prevent loosening during performance and applying grease-grade oil to moving parts to maintain smooth action.
The manual details step-by-step procedures for installing both the bottom and top cymbals using the clutch assembly and support plate. It also explains how to adjust spring tension over an 11-step range, modify the angle of the cymbal support plate, and configure the hi-hat feel by adjusting lock nuts on the clutch.
Remove the hi-hat clutch assembly, place the cymbal on the felt washer on the cymbal support plate, and adjust the angle by turning the angle bolt on the underside of the support plate.
Use the Knob Bolt located on the underside of the cymbal support to adjust the angle of the hi-hat cymbal.
Open the lock nuts off of the felt for a loose sound, or close the nuts onto the felt for a tight sound, then tighten the lock nuts firmly onto each other.
The Spring Tension Knob supplies tension control over a 11-step range.
