2.6 Attaching unit to the chair
Slide the unit pallet next to the chair. Connect power cords from the unit to the chair tempo-
rarily to position the chair. Connect the connection box to the mains temporarily. Power up
the chair and position the height of the adapter (raise the chair) so that the unit can be
placed on it easily by sliding the pallet closer.
Attach the adapter. See chapter Adapter adjustments.

2.7 Adapter adjustments
Figure 2: Adapter with bolts
Attach the black hex screws. Adjust the cuspidor horizontally and vertically straight by loos-
ening the corresponding attachment screws. Ensure that at least 8 mm of the threaded part
of the bolt is inside the hole of the patient chair body plate. When the cuspidor is in the cor-
rect position attach and tighten the bright securing hex screws.
The black attachment hex socket (Allen) screws are of type M8 * 40, hardness 12.9, non-
galvanized. 6 pcs.
The bright securing hex socket (Allen) screws are of type M8 * 30, hardness 8.8, galva-
nized. 6 pcs.

Remove the spring adjustment opening cover before adjusting the tension of the spring.
This adjusts the balance and displacement force of the instrument arm.
2.11 Adjusting the stiffness of tray rotation
Tray Arm
The stiffness of the rotation of the tray arm is adjusted with the adjustment screw (shown on
the picture). Use 3 mm hex key for the adjustment. The adjustment screw is locked with the
locking screw to prevent loosening. Use 4 mm hex key for the locking.
2.12 Headrest lock tightness adjustment
The movements of the headrest are double articulated. The headrest can be adjusted
around the two axels when the locking lever is in open position. The tightness of the locking
system is adjusted with a plastic tool delivered with the system.
Figure 7: Headrest lock tightening tool
Remove the plastic plug on the vertical bar carefully with the chisel end of the tool. Then
adjust the tightness of the nut with the key and replace the plug. The plug locks the tighten-
ing nut in its place.
