Since 1886 the Daisy Company has been making BB guns, and since then kids have considered owning one to be a right of passage. A Daisy Spring-Air BB Rifle shoots 4.5mm BBs that are fired by cocking the rifle with a lever and feeding the BBs into position by raising the muzzle and pouring the BBs into it. However, these air guns will occasionally need servicing.
Items you will need
Twenty weight oil
Service the Trigger Mechanism
Determine whether or not the trigger is working properly. You should be able to depress the trigger with very little pressure from your index finger. If the trigger sticks or does not move smoothly through its full range of motion, it needs oiling.
Place the Daisy BB gun onto some old newspaper or a shop rag as oil may leak during the lubrication process. Hold the rifle upside down to access the trigger area. Use a can of WD-40 with a straw attachment on the nozzle to aim some lubricant into the trigger mechanism itself.
Spray oil into the top portion of the trigger where it inserts into the cocking mechanism. Hold the gun upside down for 30 seconds and then flip it over to let excess oil run out. Let the rifle dry for half an hour and then wipe the trigger area with a paper towel to ensure dryness. Pull the trigger through its full range of motion.
Fixing a Jam
Determine whether the cause of the jam came from improper feeding. This can happen if you turn the rifle on its side while a BB is in the firing position. To load properly the gun needs to be held straight with a slightly raised muzzle.
Ensure that the BB was not damaged shot. A flattened or scratched BB will often jam. Shot that is excessively dirty can also create a problem. Be sure to use new shot each time you load a Daisy Spring-Air BB Rifle.
Check to be sure the correct ammunition was used. Never try to shoot anything other than proper BBs or .117 caliber ammunition.
Clear the jam by cocking and firing the gun five times. Hold the rifle straight with a slight elevation to the muzzle for best results.
- Never disassemble the gun. If improperly reassembled serious injury could occur.
- Oil the gun regularly. For best results add two drops of oil in the “oil” hole every 500 shots. A 20-weight motor oil works best.
