DM5 TROUBLE SHOOTING
AIR LEAK BETWEEN THE FRAME AND BODY
-
First remove the frame and try to pinpoint the source of the leak:
-
If it comes from the small hole under the LPR, you need to remove your LPR.
The cause of the leak is either one of the #015 o-rings on the outside of the LPR or the #006 o-ring
found inside the LPR (see page 10).
-
If it comes from somewhere around the solenoid, the first thing to do is to turn the on/off
knob to the off position. If the leak continues, the cause is a bad o-ring on the on/off.
If it stops there are three likely causes:
1. #015 on the bolt sail
2. #020 on the cylinder (the one on the middle of the cylinder)
3. Seat under the solenoid
AIR LEAK FROM THE BACK OF THE LPR PLUG
-
Remove the LPR and change the back-most #015 o-ring on the LPR body. If that does not help,
change the seal retainer inside the LPR body. Refer to page 10 of the manual for disassembly instructions.
INCONSISTENT VELOCITY OVER THE CHRONO
-
In-line regulator not giving consistent pressure: refer to the Hyper2 manual for service, or if using an after-market
regulator, refer to its manufacturer.
-
Low battery: change the battery.
-
Bad seals in the bolt: take out the bolt, clean it, lube it with Dye Slick Lube™. Replace any o-rings that seem
damaged, swollen or in otherwise bad shape. Most likely the o-ring at fault is the #017 front wall o-ring. Also
check that the #014 o-ring on the bolt tip is in place.
-
LPR pressure set incorrectly or LPR pressure fluctuating: if pressure is too low, the bolt will not cycle correctly. Try
turning the LPR pressure a bit higher. If the pressure seems inconsistent, you can have an authorized DM5 center
check the LPR pressure. List of tech centers can be found at www.dyematrix.com.
-
Dwell set too low: if you set the dwell too low, the dump chamber will not empty completely and will cause erratic
velocities. Refer to board settings page for information on setting the dwell.
TRIGGER BOUNCE
-
If you are having excessive trigger bounce when firing the gun, make sure you have an uncut spring behind the
trigger. Adjust the trigger so that the firing point of the trigger pull is located about halfway through the travel of
the pull. Raise the trigger sensitivity value.
AIR LEAK BETWEEN THE BODY AND REAR CAP
-
Replace the #020 o-ring on the bolt rear cap.
MARKER WILL NOT FIRE
-
A low battery may cause malfunctions to the marker. In this case, the battery should be changed as soon as possible.
-
Check to make sure the on/off is in the on position.
-
If the LED light is red, the marker will not fire because there is no ball in the breech. Hold the trigger for 1 second
and the marker should fire. If it does not fire after holding the trigger, or if the LED light is green and it will not fire:
-
Make sure dwell setting is at stock value.
-
Make sure the trigger is adjusted properly and is actuating the microswitch.
-
Make sure there are no broken solenoid wires.
-
Sticking bolt: pull out bolt and re-grease o-rings.
MARKER SHOOTING SLOW WHEN EYE IS ON AND BLINKING GREEN
-
The eyes are not working correctly. Clean the eyes. You'll know that they are clean if the LED turns red when there is
nothing inside the breech of the DM5.
-
Make sure the eye wires are not broken or pinched.
-
The battery may be low. In this case, the battery should be changed as soon as possible.
MARKER ISN'T WORKING THOUGH EYES ARE CLEAN AND ALL WIRES ARE CONNECTED;
MARKER DOES WORK IF EYES ARE TURNED OFF
-
Change the battery. The voltage in the battery is too low for the eye to function correctly.
MARKER WILL NOT TURN ON OR OFF, CONTINUOUSLY CYCLES THROUGH BOOT-UP, EYES WILL NOT TURN ON OR OFF
-
The membrane pad may need replacement.
AIR LEAK THROUGH THE BARREL
-
There are three possible o-rings that cause this leak:
-
If the leak comes through the inside of the bolt, replace the #013 on the bolt top hat. If the cause is this #013 o-ring,
the input pressure to the gun is likely too high.
-
If it’s leaking from the outside of the bolt shaft, the bad o-ring is either the #017 on the inside of the bolt cylinder or
the #020 on the outside of the bolt can.
AIR LEAK FROM THE BACK HOLE OF THE BOLT
-
Take out the bolt, unscrew the back part of the bolt and change the #009 o-ring on the back of the bolt shaft.
THE GUN WILL NOT TURN ON OR OFF, CONTINUOUSLY CYCLES THROUGH BOOT-UP, THE EYES WILL NOT TURN ON OR OFF
-
The membrane pad has most likely gone bad.

TROUBLE SHOOTING
NO OR POOR AIR FLOW
-
Check for blocked air passage in hose line or regulator. Adjustment screw may be screwed in too far.
-
Seat may have excessively deep piston groove cut into it. Replace if needed.
ERRATIC VELOCITY OR SHOOT DOWN
-
Piston or spring stack may be binding due to excessive dirt or lack of lubricant.
-
Seat may be dirty or damaged. Clean and grease reg. Inspect and replace damaged parts as needed.
OUTPUT PRESSURE CREEPS UP
-
Dirty seat or damaged piston face.
-
Clean and inspect; if either is damaged, replace.
AIR LEAK FROM SIDE VENT HOLE
-
Piston o-rings may be damaged. Inspect o-rings.
-
Replace if any visible nicks or cuts are found.
AIR LEAK FROM BOTTOM OF ADJUSTMENT SCREW
-
This is a safety bleed-off to help prevent over-pressurizing. De-gas the Hyper2; be sure all air is vented out of the reg. Supply air back to the regulator. The leak should stop.
If the leak persists, replace the reg seat. Make sure there are no nicks or scratches on the raised ring at the bottom of the seat-retaining cavity.
