10. Q Re assembly is the reversal of the above TIPS MAINTENANCE CLEANING GUIDE ON BACK PAGE Given the correct treatment the Inferno will perform reliably for many years Cleaning dirt and contamination from the working parts will reduce wear rates considerably so always clean your gun after use A well maintained gun will shoot more consistently and more accurately for longer Therefore your target will receive more paintballs this is what you want Always start any work on the gun by removing the CO or air cylinder and any paintball hopper To field clean the gun cock the gun and apply the safety this stops hammer from being able to rotate if trigger is accidentally pulled and exposes more area for lubrication Then remove the cocking handle by pulling upwards this will allow the bolt to be removed backwards from the breech chamber Wipe any residual paint from the feed stub and then clean the bolt using an oiled lint free cloth Using a squeegee clean straight through from rear of the marker out of barrel do not go from barrel end as this will drag contaminants into marker internals Ensure the barrel is clean by inspection any paint water or oil residue in the barrel will cause extreme inaccuracy Then squirt some Inferno lube oil available from Arrow Precision Ltd down through the cocking handle slot so lubricant reaches the hammer assembly The bolt can then be replaced into the breech after a light spray of oil rotate once
11. compressed gases can kill they must be treated with respect WARNING The Inferno may sometimes fire spontaneously if energised with a gas source without first cocking the hammer so always wear safety goggles WARNING Do not attempt to dismantle the Inferno beyond removing the barrel and bolt without first making sure that it is unloaded and de gassed OPERATING INSTRUCTIONS Section Preparing For Use Make sure that you and everyone else within range is wearing approved eye and ear protection Make sure that the safety catch is set to safe by pressing the safety catch in from the left side of the gun viewed from the rear and install a barrel safety plug into the barrel before cocking the gun by pulling the cocking handle to the rear until it locks backwards Install the gas supply and the feed system then check the muzzle velocity as in section 4 below You are now ready to play paintball Section 2 Making the Gun Safe Install a barrel safety plug in the barrel tip the gun sideways so that the ball in the breech rolls back into the feeder Then grasp the cocking handle and pull the trigger at the same time be careful to only let the cocking handle come forward slowly until it is all the way forwards Then push the safety catch to safe The gun is now safe and if you are finishing for the day you can remove the gas tank and feeder Never store the gun with the feeder or the tank installed as this can be dangerous
