Put a newspaper down on your work service, and pull the magazine out of your Beeman pellet gun.
Put the magazine on the newspaper, then put your Beeman pellet gun on its side on the newspaper as well.
Remove the screws from around the top of your pellet gun with a Phillips screwdriver. The screws are on either side and at the back end, by the hammer.
Wiggle the slide off the top of your pellet gun with your fingers. Put the slide on the newspaper.
Wiggle the spring assembly off the top of your pellet gun with your fingers, and pull out the spring from the spring assembly. Put the spring and the spring assembly on the newspaper.

Place the needle of the syringe against the inside front end of the spring assembly. Push the plunger to inject the light machine oil into the spring assembly of your Beeman gun.
Replace the spring into the spring assembly; the spring assembly into the top of your Beeman pellet gun; and the slide to the top of your gun.
