Checking The Lock Function; Securing The Screws - FIOR & GENTZ NEURO LOCK Notice D'utilisation

8.5

Checking the Lock Function

1 Lock the system joint in maximum extension.
2 Press the locking pawl downwards firmly. The extension stop is thus pressed
against the stop faces.
3 Unlock the system joint again and have the locking pawl snap as usual.
4 Check the correct position of the locking pawl. It must not be mounted too high
(fig. 27) or too low (fig. 28).
If the locking pawl is in the correct position (fig. 29), the system joint locks without
play. If the locking pawl is mounted too low, the system joint locks with play. In
this case, mount the next longer locking pawl with the same system width and
check the fit. If the locking pawl is mounted too high, the system joint might unlock
unintentionally. In this case, mount the next shorter locking pawl with the same
system width and check the fit.
If you are using a system joint with step lock function, check the lock function
exactly as described in this paragraph.

it is handed over to the patient.
1 Secure the screws for the cover plate (fig. 26) with the torque corresponding to the system width and
LOCTITE® 243 medium strength.
2 Let the adhesive harden (final strength after approx. 24 hours).
