Before troubleshooting the Axe you should always install a fresh battery and perform general basic maintenance shown in this video: General Maintenance Guide
Empire recommends Dow 33 lube to be used on the Axe bolt system. Paintball Marker oil can be used in the regulator
The tips below only pertain to the stock Axe. If you have installed aftermarket parts remove them. Set the regulator to 200psi and use the back cap to adjust velocity

Problem: Velocity is low, inconsistent, or drops during rapid fire
Solution: Try the following
-Set Regulator pressure to 200psi. Turn the back cap all the way in and unscrew 3/4 of a turn. This should set velocity to around 290FPS. Set Dwell to 8ms.
-Lube Poppet o-ring and/or replace if necessary
-Replace large bolt guide o-rings (most critically the middle one)
-Lube small bolt guide o-rings and replace if necessary. If the bolt can drop off of the bolt guide by being shaken lightly the small bolt guide o-rings should be replaced
-Lube Bolt outer o-rings and replace if necessary
- Check regulator gauge during firing. Gauge should return to set pressure quickly If not try
-a different tank
Rate Of Fire Issues:
-drop 2-5 drops of paintball marker oil to the Axe ASA/Reg and dry fire the marker
-Get the regulator serviced
Problem: Slow or Inconsistent Rate of Fire
Check your board settings. See the user manual (link above) before continuing.
If you have broken paint the eyes may be dirty. The eyes should be cleaned by removing the sensor board and cleaning the eyes. You can check the eye status on the main circuit board. See the user manual for eye status indication
If your eyes are clean Your bolt may be cycling too slowly. To fix this perform general maintenance as show in the service guide above. Wash the inside of the bolt and the small area of the bolt guide with water to get rid of paint residue. The small bolt guide o-rings may need to be replaced if they have swollen.
Problem: Breaking paint in barrel and/or breech
If balls are breaking in the barrel try re-sizing the barrel or switching paint.
If breaking balls in the breech check the following:
-Check that the ball detents are present and can move freely in the breech
-The bolt should not fall off the bolt guide when shaken . If it does replace the small bolt guide o-rings
-There is a air re-stricter valve (also known as check valve), located in the solenoid ports. If this is not installed the Axe may break paint. Check if this part is installed. See the user manual for where this piece is installed
Air Efficiency Issues:
Problem: Low Air efficiency
Confirm an good barrel to paint match.
Perform routine maintenance on the Axe. Make sure the poppet is well greased. Set the pressure to 200psi and use the back cap to adjust velocity. The less the poppet opens the faster it can close which saves air. The back cap should not need to be more than 1 full turn out from all the way in for 300fps. If velocity is not achieved the poppet o-ring should be replaced.
The bolt should not fall off the bolt guide when shaken . If it does replace the small bolt guide o-rings
The regulator should only be serviced by an authorized air smith. Servicing the regulator may void your warranty. Empire recommends sending the regulator to Empire Customer Service at paintballsolutions.com Should you not be able to send in the regulator a PBNation community member has made a relay regulator service guide: Relay Regulator Service Guide
Problem: Regulator pressure rises slowly as marker sits idle. Or after first shot regulator pressure doesn't return to set point in less than 1 second.
Solution: replace the regulator washer (also known as regulator seat or main seal).
Problem: Regulator pressure recharges slowly after a shot causes low velocity
after first shot.
Solution: lube and/or replace the o-rings on the large brass piston with Dow33 (not oil)
Problem: Regulator doesn't vent or takes several minutes to vent when tank is removed.
Solution: This may be because the depression pin is not moving freely. Apply oil or grease to the pin to get it to slide more easily.
Problem: Large leak in breech/barrel
Solution: This leak is usually caused by the solenoid being held open. With the air off turn the marker on and turn the eyes off to click the solenoid
Problem: Small leak in breech/barrel
Solution: This leak is caused by the white poppet or the bolt guide where he white poppet touches. First try replacing the white poppet. If this doesn't work you many need a new bolt guide. Contact Empire warranty service at paintballsolutions.com for a replacement.
Problem: Solenoid doesn't click until I pull the trigger many times or at all.
Usually the battery just needs to be replaced or the solenoid needs to be cleaned. To clean the solenoid follow the solenoid service guide: Cleaning Axe Solenoid
Problem : On Shockwave board when I press power button the gun flashes a bunch of colors an then the light turns off and the board doesn't do anything
Solution: Your Shockwave board is starting up in programming mode. When you hold the trigger while turning on the Shockwave board it starts programming mode where you can change settings like Fire mode or rate of fire for example. You should adust the trigger until the trigger is no longer being depressed.
Problem: With a Shockwave or Redline board the marker fires very slow with eyes on but is ok with eyes off.
Solution: This means you have an eye malfunction so the eyes are dirty or damaged or the connection from the main board to sensor board is not there. First try cleaning the eyes by removing them from the marker. Also clean the holes the eyes see through. Check the sensor board and connections for corrosion or bent pins.
