An air gun loses its effectiveness when oil inside of the firing chamber becomes sticky and adheres to the chamber. You can make your air-powered rifle more powerful by lubricating the insides of the air chamber and barrel, which is called "dieseling." You will need a few parts from a hardware store and about an hour to complete the process. You do not need to take apart the air-powered gun, so the warranty will not be affected.
Release the magazine latch on the side of the trigger guard of the air-powered rifle. Pull the magazine out of the bottom.
Pull out and back on the cocking handle, then fire into a dustbin to verify that there is no ammunition in the firing chamber.
Insert one end of the tube that comes with an aerosol machine oil can into the can's nozzle.
Pull out on the cocking handle of your air-powered rifle.
Place the free end of the oil tube into the air chamber hole that is at the back end of the firing chamber, near the hammer.
Press down on the oil can nozzle and release it after 10 seconds. Remove the oil tube from the rifle's air chamber.
Pull out and back on the air gun's cocking handle. Repeat this procedure for five minutes.
Place the free end of the oil tube into the barrel of the gun. Press down on the nozzle for three seconds, then remove the tube from the barrel.
Insert three flathead pellets into the magazine. Push the magazine back into the bottom of the air-powered rifle.
Pull out and back on the cocking handle. Fire a pellet into the dustbin. Repeat this another two times.
Release the magazine latch on the side of the trigger guard. Pull the magazine out of the bottom of the gun.
Wait five minutes, then repeat the procedure of spraying aerosol machine oil into the chamber hole and barrel.
Repeat the procedure of putting flathead pellets into the magazine and firing them; fire six pellets this time, instead of three.
Wait 10 minutes, then pour four drops of motor oil into the barrel.
Pour four drops of motor oil into the air chamber hole.
Insert 10 regular round pellets into the magazine. Push the magazine back into the bottom of the air gun.
Pull out and back on the gun's cocking handle.
Fire into the dustbin. Repeat this nine times as rapidly as you can.
A well-ventilated location is necessary when spraying a lubricant into an air-powered rifle gun.
Never aim a weapon of any kind, real or toy, at a person or a domestic animal. Do not lubricate an air-powered gun whose manual forbids doing so.
