•
The DM4 marker is not a toy. Misuse may cause serious injury or death.
•
Please read, understand and follow the directions in the DM4 owner’s manual.
•
Eye protection that is designed specifically for paintball and meets ASTM/CE standards must be worn by user
and persons within range.
•
Recommend 18 years or older to purchase. Person under 18 must have adult supervision.
•
Always treat the DM4 marker as if it were loaded and able to fire.
•
Only use compressed air or nitrogen gas in the DM4 marker. DO NOT USE CO
2
.
•
Do not exceed 800 psi input pressure.
•
Ensure all air lines and fittings are tightened and secured before gassing up the DM4.
•
Always chronograph the DM4 marker before playing paintball.
•
Never shoot the DM4 marker at velocities in excess of 300 feet per second,
or at velocities greater than local or national laws allow.
•
Never look into the barrel or breech area of the DM4 when the marker is switched on and able to fire.
•
Always fit a barrel blocking device to your DM4 when not in use on the field of play.
•
The owner’s manual should always accompany the product in the need of reference or the event of
resale and new ownership.
•
Do not point the DM4 marker at anything that you do not intend to shoot.
•
Do not shoot at people, animals, houses, cars or anything not related to the sport of paintball.
•
Do not fire the DM4 without the Fuse bolt screwed in completely.
•
If you read these instructions and do not fully understand them or are unsure of your ability to make
necessary adjustments properly, call DYE or your local pro shop for help.
Air Supply -
The DM4 should be operated using air/nitrogen gas only. This air needs to be supplied to the Hyper2 in-line
regulator at a regulated pressure of no more than 800 psi. The Hyper2 in-line regulator comes factory preset at 175psi.
Turning On Your DM4 -
The DM4’s power is controlled by a simple two button membrane pad. The top button turns the
marker on and off, while the bottom button turns the eye on and off. Hold the power button for 3 seconds to turn the
marker on. The LED in the grip will illuminate during the boot sequence.
NOTE: If the eye is not working properly, try replacing the battery.
Blue
- Boot Sequence
Solid Red
- Breech is clear, no ball (eye on)
Green
- Ball in breech, ready to fire (eye on)
Blinking Red
- Eye is off
Blinking Green
- Eye failure (see DM4 Board, page 13)
On/Off -
The On/Off knob is located under the barrel at the front of the DM4. To turn the gas
on, turn the knob counter-clockwise. To turn the gas off, turn the knob clockwise. All gas will
vent from the DM4 when the knob is turned off. Air may still be present in the LPR and solenoid
after the air has been vented from the gun, by the on/off. Be sure all air has been vented by
discharging the gun in a safe direction. If servicing the gun removal of the bolt will also allow any
trapped air to escape.
LPR
- The LPR is pre-set from the factory at approximately 75-80 psi and should need no adjustment
out of the box. If fine tuning adjustment is desired or needed you must be sure that you are adjusting
the LPR correctly. See page 10 for detailed instructions. If the LPR is improperly adjusted you could
dramatically hinder the DM4’s performance or prevent the marker from functioning at all.
NOTE: Turning the adjustment screw clockwise, or in, will lower the LPR’s output pressure. Turning the
adjustment screw counterclockwise, or out, will raise the LPR’s output pressure.
Hopper -
To get the best performance out of your DM4, it is recommended that you use a motorized loader. Preferably
one that force feeds the paint really, really fast!
Feed Neck -
To secure your loader into the adjustable feed neck use a 5/32 Allen wrench.
Be careful not to over tighten the collar as it can cause the neck to beak.
Adjusting Velocity -
The velocity is adjusted through the Hyper
2
in-line regulator. The Hyper
2
in-line is pre-set from the
factory at approximately 170 psi. This pressure setting should have the marker shooting at about 285fps. Your paint-to-
barrel fit will also have a noticeable affect on your velocity. Make sure that the paintball fits into the barrel loosely but does
not drop through.
NOTE: For the Hyper
2,
turning the adjustment screw clockwise, or in, will lower the output pressure, decreasing the velocity.
Turning the adjustment screw counterclockwise, or out, will raise the output pressure, increasing the velocity.
NOTE: If the battery is too low, it may not be able to power the solenoid correctly. This will affect your DM4’s velocity, causing it
to become inconsistent and/or low.
