9. ADJUSTING THE EJECTOR SPRING FORCE
Depending on the door size and type of the hinges you might need to adjust the spring force.
Ejector is important part of the lock and should be able to push the doors open when unlocked.
For the great majority of locker and hinges type factory settings (normal spring force) are in order.
However in some cases (very small doors, spring - shut hinges, etc.) the spring might need to be
adjusted. There are two stronger positions and two weaker positions (from approx. 0.5 to 1.5 times
of original force). With this intention a 2.5/16 mm screw is supplied. Be sure to screw it all the way
in so the head is level with the lock base.
For stronger spring, simply screw it into one of the two positions on the bottom of the body (see
picture) the one closer to the ejector end being the stronger one ("A").
For weaker - shorter ejecting travel, first compress the spring totally with the thumb and then
screw-in the screw, the position closer to the ejector end now means less ejecting travel (compress
& position "A").
ATTENTION
Do not over-compress the spring (force ejector inside
the lock), as you might damage the switch!
