A person can make the pump easier to operate on a Crosman 760 air rifle by applying oil to the seals. This will provide lubrication and improve the overall action of the weapon.

You have to swing the forearm to pump up an air cylinder in the rifle. Usually it take about 8 pumps. When you pull the trigger it releases the air an propels the BB or Pellet.
Both Daisy and Crosman made air guns/BB for Sears. I believe you are asking about the Crosman model 760 pump repeater Rifle. there are several variation's of the 760 starting in 1966 all the way to today. However Sears stopped selling gun in 1980 so yours is before 1980. I would think yours would be closer to the 1960 date because the later sears model 760 carried a model number of 126.19331.go to http://www.pyramydair.com/ and do a search for 760 to see if this rifle looks similar to your rifle.
