Air Gun Maintenance
Careful and, what is more important, regular maintenance is the main condition of reliable Air Gun functioning and safety. There are several basic rules every airgunner should follow.
Never keep your Spring-Piston Air Guns cocked. It causes spring fatigue, thus you will have to change a spring rather often.
If you have charged your CO2 Air Gun with a CO2 cartridge do not keep it charged more than 2 weeks (24 hours is recommended).Rechargeable air-cartridges may serve for a month. Then a day or two are necessary to restore the original form and elasticity of rubber seal.
Using a high-power rifle do remember to tighten all screws that tend to unscrew after 30-40 shots.
Never drop or hit your Air Gun. Many important components of Air Rifles and Air Pistols are often made of silumin (a kind of aluminum alloy) and other fragile materials. Plastic details and wood stocks can also be broken.
It is not recommended to use low-quality cheap pellets, improper or handmade pellets, because they may be jammed in the barrel. Jamming of several pellets may cause an irreversible damage of a rifled barrel after the barrel is cleaned with a ramrod.
Cocking a rifle with a Break Barrel Action hold the barrel with one hand and the butt stock with the other hand. Do not cock it with a jerk carrying the rifle in one hand (in the way cinema heroes do). Move all the levers smoothly with necessary effort. Do not apply excessive effort moving a trigger, a cock or levers. .
Very often if you pull a trigger when your Air Gun safety is “ON SAFE” position you can seriously damage percussion trigger unit.
With the course of time pellets tend to jam in rotary magazines. In this case pulling the trigger with unnecessary effort you can damage a gun.
Some shooters use oil, gasoline or ether in order to increase muzzle velocity. They drop a liquid into the working chamber or inside a pellet itself. When the gun shoots a momentary pressure growing in air chamber leads to oil inflaming that becomes a source of additional energy affecting a projectile (so-called a “dieseling” effect). However combustion products remain in a cylinder and other parts and spoil a piston mechanism. In order to avoid negative consequences of “dieseling” in Spring-Piston Guns it is recommended to use the minimum quantity of oil (a drop or two) and load a rifle with lightweight pellets or felt wadding for the fist three or four shots after oiling. There are also special gun oil with graphitic, molybdenic and silicone additive agent that do not cause a “dieseling effect”.
Do never dry-fire your Spring Piston Air Gun. For a powerful “Magnum” class Air Rifles choose heavy-weight pellets (0.6 gr. and more).
Be careful charging CO2 rifles with CO2 cartridges. Do remember that pressure of leaking gas is 60 bar and the temperature is -94˚ F. Remove and install CO2 cartridges according to manual. For example for installing a cartridge, firstly put a cylinder into a grip then tighten a piercing knob towards CLOSE thus piercing cartridge membrane. For removing a CO2 cylinder turn a piercing knob towards OPEN, until you hear gas start to escape, continue turning the knob, remove a backstrap and drop out a CO2 cylinder. Construction of CO2 device and the actions may be different but the main principle is the same: do not come in contact with the escaping gas.
If the quantity of shots per one CO2 cartridge decreases with the course of time, it may indicate gas leakage. Probably it is time to change o-ring or CO2 feeder unit.
A regularity of examination and cleaning of Air Guns is not as critical as in case of firearms. But proper maintenance will guarantee a long life of your Air Gun. Clean your gun after buying in order to remove factory conservation oil, clean it after shooting and after staying outdoors. If there is a condensate on a gun dry it with a piece of cloth before cleaning. Oiling the gun follow instruction of the manual.
Usually it is not necessary to disassemble a pistol or a rifle before cleaning. If it is necessary to do it follow the user guide. If you are not experienced enough ask an airgunsmith to repair or clean your Air Gun.
Examine the gun before cleaning, if there are any defects of metal and wood parts, unscrewed bolts, rust etc. Then oil the critical points of air compression system, rubber and synthetic rings, piston cup and compression chamber. Make several shots in order to spread the oil inside the mechanism. Use special hard oil for springs of Spring-Piston Air Guns. Oil barrels of powerful (magnum class) rifles after every 40-50 shots otherwise it will shoot less accurately. In CO2 guns oil sealing o-rings after every shooting or changing every third cartridge. Oil the percussion trigger unit after 1500-2000 shots. Oil all the levers and piercing knob of CO2 gun when it is necessary. Wipe the gun. Finely use neutral oil and wipe all the metal components one more time with a piece of cloth. Do never oil wood stock.
AND REMEMBER THE GUN IS ALWAYS LOADED AND READY TO SHOOT.
