12.2 Adjusting the brakes
NOTE!
The following steps apply to spring arms mounted
to a height adjustment tube as well as spring arms
mounted directly to the swivel arm.
Adjust the braking action of the individual joints so that the light
head stays in any given position. If the suspension arm of the
surgical light drifts, tighten or replace the appropriate brake screw.
CAUTION!
Risk of injury if braking action of joints fail!
If the brake screws are lubricated or residual
lubrication is left on them, they lose their braking
action and the articulated joints will not stop as
desired when moved.
Therefore:
– You must ensure that the brake screws are
completely free of lubricant!
– Residual lubricant on the brake screws must be
removed immediately, e.g. with petroleum
ether solvent!
