No It is not a repeater , you must re cock and and hand load a pellet after each shot!
Release the clip on the left side and let the slide pop back. Grab the front end of the barrel and push it down. load the pellet directly into the barrel. close the barrel. cock the gun normally and fire. It is a single shot pellet gun.
Your best bet is to contact Marksman directly See the link below

There's a double action to the slide - see the link below for a manual:
Ask a gunsmith for help
you put the magazine into the butt of the pistol, then to charge the pistol pull the slide to the rear and let go or push down on the slide catch if there are no more rounds in the magazine.
