## Installation

- Details
In this position the two large holes in the front part line up with the countersunk holes of the base bracket. Place the base bracket against the side wall of the frame and fix it with wood screws through the three countersunk holes.
- Details
Set the side rail of the visible seat frame on the top face of the upper bar; screw it from above (the screws pass through the rail into the hole and the two slots in the top flange of the bar).
- Details
Screw it from above into the hole and the two slots in the top flange. The backrest is fixed and is not attached to the mechanism.
- Details
Tighten an M6 bolt and nut through the square hole (fixed) at one end and through the slot (adjustment) at the other; the slot allows for a tube cut slightly short.
- Details
The hidden seat rises and both surfaces come level. Push it back to close. Both sides must move together without catching.
