Important Notice Because the NOVA series markers are totally pneumatic, 0-rings and 0-ring maintanance are very important. Dirt, sand, weather, lack of lubrication, friction, ozone and other contributing factors ensure eventual wear not only on 0-rings but parts as well. Although operation and maintenance require minimal attention, no attention will eventually cause failure. Take care of your marker and it will take care of you. We will address the most common troubles and yet easy to fix in this section. WHENEVER DOING MAINTENANCE WORK ON MARKERS-NEVER USE BALLS OR HAVE A LOADER ON THE UNIT. IMPORTANT: there are times when air is necessary in the middle of some maintenance operations. Other times it can be dangerous. We will be very specific on when, where and why air should or should not be applied. Be very specific where you have a problem or leak. A squirt bottle with a small amount of soap in it will help locate and isolate problem areas.
MyMa r k e rWon’ tSho o t Notice: First things first. Check to make sure your bottle has air.
-Barrel Won’ tMove Barrel won't move..The velocity is set at the factory between 250-280 fps. The velocity screw is always loose and wobbly when not under pressure. Under pressure it will become solid. A. If the pressure is too low the barrel will not move to the closed position……. . Adj us t velocity screw clockwise (increase) until barrel moves to the closed position. Adjusting the velocity screw too far will cause the marker to overpressurize and start relieving. B. The brass ring on the exposed portion of the barrel that holds the center 0-ring has moved. It is 1" from the end of the barrel to the beginning of the brass piece. Send the barrel to AirStar for replacement. C. The barrel spring retainer on the barrel assembly has slipped off. This is an easy fix-see BARRELS.
-Trigger Is Sloppy Or Frozen Or Both. Trigger is sloppy or frozen or both. A. The set screw in the trigger has come loose. The trigger is attached to the trigger rod which moves back to actuate the cartridge valve. When the set screw becomes loose the trigger can't move the rod toactuate the valve. Tighten set screw and read TRIGGER HOUSING for proper adjustments. B. The brass sleeve in the trigger housing has become loose and moved forward. Degas marker and remove air source for the following adjustment. The brass sleeve is located in the trigger hole slot directly behind the trigger (same hole as trigger). In most cases you will only see a small portion of it sticking out. (1/32" to 1/16") Behind the trigger is a set screw. This is a double set screw. Remove the top one and loosen the second one. Then with a jewelers screwdriver push the brass spacer back into the trigger housing and tighten the set screw. If you push the brass spacer too far into the trigger housing your safety may not work. Always test your safety after making the spacer adjustments. If the safety doesn't work you have moved the brass spacer too far into the trigger housing. Loosen screws again and move spacer forward 1/32" or until the safety wor ks ….Tighten screws. See: TRIGGER HOUSING for proper adjustment.
Barrels -Disassembly Of The Articulated Barrel Assembly (ABS) Pull back the foam on the foregrip where it meets the barrel assembly. There are 3 screws --remove and pull the whole foregrip off. Loosen-don't remove the set screws on the barrel spring retainer (small black ring that holds the spring in place)…. .remove the
spring and barrel retainer. Don't forget to clean and lube the 0-ring inside the barrel retainer. ==IMPORTANT==IMPORTANT == Reattaching the barrel spring retainer. ==POSSIBLE BARREL DAMAGE== It takes very little pressure from the set screws on the barrel spring retainer to hold the ring and spring in place. It takes very little pressure to put a big dent on the inside of your barrel if you're not careful. Tighten one at a time in small (baby) increments. Work the c i r c l ea n dg oa r ou n da g a i n ….small increments.
-Barrel Lubrication The importance of keeping the 0-rings lubricated is vital to the timing and firing sequence. The barrel must be able to move easily at all times. Lubricating and keeping clean the 0-ring inside the barrel spring retainer is critical. Pull back the barrel and drop some oil on the barrel to lube this internal ring. Small paint skins from ball breaks can get into the barrel spring retainer and prevent free-flow of the barrel. Taking off the foregrip and rinsing any debris can help.
-Whacky Ball Pattern It is very important to keep your barrel as clean and dry as possible. AirStar uses lubricants during assembly which end up in the barrel after the marker is gassed up. When you first get your marker you may encounter this situation. Most of this is attributed to oil from assembly and must be removed several times before it disappears.
-Jumping Barrel Assembly Possible over lubrication of the large (222) 0-ring on the barrel retainer or a small piece of solder buildup where the brass ring is attached 1" from the end of the barrel. With a small file work the solder down until smooth with the ring. Some barrels are soldered on both sides of the ring.
-Chopping Balls Free movement of the barrel is critical in the timing and firing sequence. Keep the 0-rings on the barrel lubricated well. Chopping can be caused from a variety of sources: 1. 2. 3.
Bad paint Paint skins in the barrel retainer Holding back on the trigger too long between shots. (Here is the rational )

Recognizing Regulator Problems The regulator is located in the back of the body housing. The velocity screw is a part of the regulator assembly. It is held in by two screws..The site rail screw and a screw…
