T4E Trouble Shooting and Preventative Maintenance Tips:

Feeding issue during 1st use: When the rifle is new it is best to break it down and use the T4E oil on the bolt assembly and the brass wind pipe that the magazine connects to before 1st use. The gun is mostly dry when shipped and oiling allows for best function. You may experience short cycles and have to charge the rifle after each shot if it does not have proper lubrication. You should also add 2 drops of T4E oil to the top of the magazine as seen on page 9 of the manual for the 1st use. Double charging the gun will cause the extra round to fall out of the barrel.

Low power shots, feeding issues and loss of accuracy: The CO2 is most likely spent and needs to be changed. The CO2 will last 40 to 45 shots for best performance. If the CO2 leaks from inside the magazine check the tightness of the piercing screw. If the seal around the top of the CO2 is damaged then this can also cause leaking when the screw is completely tight. If the seal is pinched you may be able to replace the CO2 and reposition it to fix the leaking. If the seal is damaged then replacement will be necessary. Page 4 of the operator’s manual has detailed information under the “Handling CO2” section. Do not leave the CO2 inside the magazine when you store it after use as it can cause the seals to breakdown and leak.

The bolt is not locking back on last shot: The most likely cause is the follower is not coming to the top of the magazine. Check for debris in the mag well, check the lever on the top left side of magazine. If the screw holding it in place is too tight or damaged, it will prevent the follower from coming to the top of the magazine. When the follower is locked down inside the mag well this lever will move with ease by hand allowing the follower to extend out of the top of the magazine when it is empty.

When using powder or paintballs: If a ball ruptures in the gun or magazine it will need to be cleaned of debris thoroughly. The gun will most likely have feeding issues and rupture more balls in the chamber. If a rupture is in the magazine it can push debris into the gun. The powder can mix with the oil producing a gritty goo. The bolt assembly will have to be removed, cleaned and oiled. The complete removal procedure for the bolt assembly is located on page 8 of the operator’s manual and on the backside of the loading and function instruction sheet. It is not recommended to store the marker rounds or leave them out in extreme cold or high heat conditions. The cold makes them hard and brittle where excessive heat will cause them to become soft and rupture easily. When using in warmer conditions keep them shaded and not exposed to the sun while not in use. The accuracy on powder and paint balls is ideal at 30 feet or less. If a round is too small it may roll from the barrel when pointed in downward angle. There is a detent in the barrel to hold the round in place for firing but can allow the smaller out of spec rounds to fall out of the barrel. If the gun is charged 2 times the extra round will fall from the barrel.

When using rubber balls: If the balls are exposed to warmer humid conditions they can become tacky and sticky. This will cause feeding and issues. To remedy it is best to add T4E oil or a synthetic silicon oil to the bag of rubber balls and work throughout the bag to distribute the oil over the rubber balls before using for best function. If reusing rubber balls be sure to clean them and add the T4E oil for best function in the gun. Rubber balls have best accuracy at 100 feet out to 150 feet.

When using the gun outside: Do not store the gun, magazine or supplies in the sun. For best performance have a covered or shaded area to stage the guns for an exercise. Wait until ready to use to load and pierce the Co2 in the magazine. When in high heat conditions the Co2 can expand resulting in higher operating pressure and cause leaking around the seals producing abnormal power shots and malfunctions. Page 4 of the operator’s manual has detailed information under the “Handling CO2” section.

CO2 Handling: CO2 capsules can be affected by certain conditions impacting proper performance. Fast consecutive shooting will result in lower velocities, diminished accuracy and less shots per CO2 capsule. In colder temperatures it is recommended to allow for more time between shots. This will allow the gas to increase in temperature and pressure to produce normal velocities. High Temperatures can increase pressure in the CO2 and when inside the marker it can cause it to malfunction. The temperature should never exceed 122 degrees for the CO2. This can be reached by leaving the marker in direct sunlight for a longer period of time. Above this temperature it could explode causing severe injury and damage to the marker. Page 4 of the operator’s manual has detailed information under the “Handling CO2” section. Do not leave the CO2 inside the magazine when you store it after use as it can cause the seals to breakdown and leak.

The Bolt Assembly: This is a wear component of the gun and will wear out between 3000 and 5000 rounds fired. It is recommended to replace the bolt assembly every 3000 to 3500 rounds fired for optimal performance. If the rubber seal on the launcher is damaged it can cause low power shots. If powder and debris build up in the bolt it will cause function issues. Keep the bolt clean and oiled with T4E oil. When the bolt becomes worn it will be very hard to actuate the launcher or a stress fracture can be seen on any of the 3 wall sections of the launcher. The complete removal procedure for the bolt assembly is located on page 8 of the operator’s manual.

For excess powder or paint buildup: Most of the paint or powder can be wiped out easily. The paint and powder can be cleaned also using warm soapy water. Do not use petroleum based oil or regular gun oil in the air guns. Petroleum based oil can cause a combustion effect in air guns called dieseling that can damage them. The guns function best when clean and oiled with T4E oil.
