I don't know english grammatic as well as I wish. And I cannot translate user manuals well. But if you something misunderstand in your Almaz - please, ask me through e-mail, I send answer on your question and put answer here. Almaz, basically, worked as other mechanical SLR-camera.

IMPORTANT NOTE.
Don't cocking the selftimer BEFORE shutter is cocked! It may be cause malfunction of shutter(not fatal, but workshop service is needed).
