1.
Installation of a rigid shank on top of a Superfit may impair its
resiliency Wider shanks in particular may be rendered inoperative. Wider
rings under size 5¼ should be tapered to increase spring tension and ease
opening and closing.
2.
If there is resistance in closing, check if tongue is flush with inside
radius and centered. Both extension balls should make a uniform
contact before closing.
3.
If the spring tension is fading without abusive wear, check for cracks in
metal or weakness within the top section. If the problem persists, a wider
shank will provide more resistance against bending stress.
4.
If the latch is depressed and returns to a closed position, check if the
tongue is flush with inside radius. Otherwise, stretch the tongue at the
end area a hair at a time until it works.
5.
If the latch does not trigger a separation, it could be dirt between the
latch tail and bottom shoulder. If the ring is on the customer's finger,
soak in warm water. Afterwards, depress the latch while pulling apart the
shank to overcome the frictional hold.
6.
If the latch slips out during a pull test, redress the hook cavity wall
and bend down the latch hook very slightly.
7.
If the latch hook is bent down too far and is hard to open, slide the ring
over the mandrel, guide the interlock over the mandrel groove and pull
down gently until you see a separation gap of under .020, enough to
straighten the latch hook. Handle with care to avoid metal distortions
8.
When the Superfit is delivered to customers or sent out for plating,
polishing, stone setting or engraving, make sure they are familiar with
handling a Superfit and attach a warning note: DO
NOT PULL AT THE LATCH!!
If the latch has been abused and must be replaced, it is not covered by
the warranty. |
