This is a Yamaha HS650 Hi-Hat Stand owner's manual
The Yamaha HS650 is a hi-hat stand designed for musical performances. This manual guides users through the initial setup of the bottom and top cymbals using the support plate and clutch assembly. It details how to adjust the angle of the cymbals and modify the sound feel by adjusting the lock nuts on the clutch.
Remove the hi-hat clutch assembly and place the cymbal on the felt washer, then turn the angle bolt on the underside of the support plate.
Open the lock nuts off of the felt for a loose sound, or close them onto the felt for a tight sound.
Apply grease-grade oil, such as lithium grease, to all moving parts as needed.
