Welcome to our forum.
keep your hands and feet within the footwell at ALL times!!!
So that's what CalSpa means by "Switchless" motors!
Hands and feet are not what I would be concerned about.
No need to be concerned, just think of it as a soak and a shave all at the same time.................
Soak and a shave would be all good... I just wouldn't want any balls floating in the tub.
Did you ever see the old "Bass-o-matic '76" fake commercial on Satureday Night Live from many moons ago. This is kind of an updated version.
