bearing sheath with the corresponding holes on the bearing sheath on the wall unit, as shown in Fig.
18.0.

MAINTENANCE ONLY
9. Unscrew the end cap for access to the spring balance adjustment, as shown in Fig. 18.0.
10. Adjust the spring balance: using a 4mm allen key, adjust the screw inside the knuckle. Clock-
wise/Tightening the screw will cause heavier engagement of the spring - this will improve ‘head
droop’. Anticlockwise/loosening the spring balance will fix a ‘rising head’ issue, as shown in Fig 18.0.
11. Friction adjustment: Clockwise/tightening this screw will apply more friction to the arm mecha-
nisms, as shown in Fig. 18.0. The arm will require more force to move, however will not continue to
move with moment. This should be set to the staff preference.
