DM4 TROUBLE SHOOTING
AIR IS LEAKING BETWEEN THE FRAME AND THE 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 #13 o-rings on the outside of the LPR or the #6 o-ring
found inside the LPR.
See page 10.
-
If it seems to come from somewhere around the solenoid, the first thing to do is to turn the on/off
knob to 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. #15 on the bolt sail
2. #20 on the cylinder (the one on the middle of the cylinder)
3. Seat under the solenoid
THERE IS A LEAK FROM THE BACK OF THE LPR PLUG
-
Remove the LPR and change the back-most #15 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
-
There are multiple causes for this problem. Below is a checklist of causes of velocity fluctuations:
1. Inline regulator not giving consistent pressure: refer to the Hyper
2
manual for service, or if using
an after-market regulator, refer to its manufacturer.
2. Low battery: change the battery.
3. 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 bad shape otherwise.
4. 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 Matrix center check the LPR pressure.
List of tech centers can be found at www.dyematrix.com
5. 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.
LEAK BETWEEN THE BODY AND THE REAR CAP
-
Replace the #20 o-ring on the bolt rear cap
MARKER WILL NOT FIRE
-
If the LED light is red, the marker will not fire because there is no ball inside the marker.
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, check your trigger settings to make sure the micro switch is actuating.
Refer to trigger adjustment page for information on setting the trigger. Last cause can be a broken solenoid wire:
check that the solenoid wire is properly connected to the board.
-
Check to make sure the on/off is in the on position.
MARKER SHOOTING SLOW WHEN EYE IS ON AND BLINKING GREEN
-
The eyes are not working correctly. Try cleaning the eyes. You know that they are clean when the LED turns red
when there is nothing inside the breech of the DM4.
THE EYE IS CLEAN AND ALL THE WIRES ARE CONNECTED BUT IT IS STILL NOT WORKING.
IF THE EYE IS TURNED OFF THE DM4 WILL WORK.
-
Change the battery. The voltage in the battery is too low for the eye to function correctly.
AIR LEAKING THROUGH THE BARREL
-
There are three possible o-rings that cause this leak. If the leak comes through the inside of the bolt, the o-ring that
is leaking is the #13 on the top hat part of the bolt. If it’s leaking from the outside of the bolt shaft,
the bad o-ring is either the #17 on the inside of the bolt cylinder or the #20 on the outside of the bolt can.
THERE IS A LEAK FROM THE BACK HOLE OF THE BOLT
-
Take out the bolt, unscrew the back part of the bolt and change the #9 o-ring on the back of the bolt shaft.
HYPER
2
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 LEAKS FROM SIDE VENT HOLE
-
Piston o-rings may be damaged. Inspect o-rings.
-
Replace if any visible nicks or cuts are found.
AIR LEAKS OUT BOTTOM OF ADJUSTMENT SCREW
-
This is a safety bleed-off to help prevent over-pressurizing. De-gas the Hyper
2
; 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.
