Troubleshooting
5.1
Functional disorder of the lever handle
The lever handle does not return to its original position by itself.
f
Check that the lever handle is correctly seated.
•
The lever handle must not have any contact with the rose or the plate or the gear box.
f
Check the tightening torque of the screwing of the handle set.
•
If the screwing is too tight, the routed pocket could be distorted and exercise lateral pressure on the gear
box, causing sluggishness.
f
Check the dimensions of the routed pocket of the main lock.
•
If, in spite of the specified dimensions being observed, the lever handle does not return to its original
position by itself, the multi-point lock must be checked by KFV.
•
If the routed pocket does not comply with the specified dimensions, it must be reworked.
f
Repeat the test step with the reworked routed pocket.
•
If the lever handle continues to fail to return to its original position by itself, the multi-point lock must be
checked by KFV.
5.2
Functional disorder of the latch
The latch runs with difficulty, does not extend completely, or does not extend at all
f
Check the specified dimensions of the routed pocket of the main lock.
•
When the routed pocket is compliant with the specified dimensions and the sluggishness persists,
the multi-point lock must be checked by KFV.
f
If the routed pocket does not comply with the specified dimensions, it must be reworked.
f
Adjust the frame part.
5.3
Functional disorder of the profile cylinder
The key cannot be pulled out.

Repeat the test step with the new cylinder lock.
•
If the key still cannot be pulled out, the multi-point lock must be checked by KFV.
5.4
Sluggishness during locking and release of the main lock
f
Check the adjustments of the AT piece and the cams.
•
Adjust the AT piece and the cams in the direction of the door leaf to reduce the lateral contact pressure.
f
Repeat the test step with the readjusted AT piece and the readjusted cams.
•
If this sluggishness persists, the dimensions of the routed pockets of the main lock and auxiliary box must
be checked.
•
When the routed pockets are compliant with the specified dimensions and the sluggishness persists,
the multi-point lock must be checked by KFV.
•
If the routed pockets do not comply with the specified dimensions, they must be reworked.
