No-one seem to have a diagram on the repeater but I did find this on the web.

Scroll down to the bottom of the page and you will find photos of how this guy put his back togather. Photos may have to be opened via an Icon on the left of the web screen.
You can load as many BB into the repeater as it will hold, BUT only one pellet at a time can be loaded into the barrel. One shot one pellet.
No It is not a repeater , you must re cock and and hand load a pellet after each shot!
It's a 16 shot BB repeater or a SINGLE shot pellet rifle
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.
Zero. Crosman doesn't make Marksman, Marksman does. The Marksman holds around 18 BB's or 1 pellet or dart.
Do not use regular oil, only use Crosman Pellgun oil or RWS pellgun oil. It can be purchased at most sportingoods shops that sell pellet guns. You can also order it online (See the link below.)
Yes it will sting or possibly injure the animal. Even though it's a relatively slow firing pistol. 200 FPS. The pellet will sting if fired a a close range. If you hit a rodent or very small animal it will penetrate the body.
Contact the maker for a replacement manual
On the left side, release the thumb latch and let the slide jump back. grab the very nose on the front of the pistol and tip it down. Load bb's in the top chamber or load a pellet in the bottom barrel (But not both at the same time.) Close the barrel. Pull the slide all the way back and push it forward until it locks. You are now ready to shoot.
It will use any .177 caliber pellet
BB's or a single shot .177 caliber pellet.
Your best bet is to search the web under "Airgun Repair" and try to locate someone who repairs Marksman products. Or contact Marksman directly and ask them. See the link below
