what cover are you talking about? If it is to the strainer basket, you absolutely should not take the cover off when the pump is on. Can you take a picture with what you are talking about?
Someone just posted a question about not getting any prime in their pump. It is possible you might need to take the cover off and fill it with water, put the cover back on and start the pump to prime the pump. However it is also possible the pump will prime by itself if you just turn it on.
