When a beautiful flashlight, which stayed at the edge of the ocean during some time, makes a light noise near Z57 when it's on. What is it necessary to make?
And indeed I simply put a few WD40 in Z57 clicky, and men, it works now to the perfection.
Other notices on the subject?
WD-40 is not very kind to rubber push buttons, besides with time the lubricating qualities will evaporate, try using silicom oil that is not destructive of rubber, the kit for my air-rifle come with a long serynge type applicator and you can put the drop of silicom oil exactly where you want.
