DM4™OWNER’ S MANUAL
WARNING
IMPORTANT SAFETY INSTRUCTIONS AND GUIDELINES
• 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 Hyper2in-line regulator. The Hyper2in-line is pre-set from the
factory at approximately 170 psi. This pressure setting should have the marker shooting at about 285fps. Your paint-tobarrel 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 Hyper2,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.

QUICK REFERENCE - Using your marker.
DM4 BOARD - Settings and Functions. DM4 BOARD - Settings and Functions (continued).
When servicing your marker:
•Make sure a barrel sock is fitted
to the DM4.
• Make sure your hopper is removed
from the DM4.
• Make sure there are no paintballs in the
breech of the DM4.
• Always remove the first stage regulator and
relieve all residual gas pressure from the
DM4 before disassembly.
• The DM4 can hold a small residual charge
of gas, typically 2 shots, with the first stage
regulator removed. Always discharge the
marker in a safe direction to relieve this
residual gas pressure.
WARNING
• The DM4 is not water resistant.
Excess moisture can cause damage
to electronic parts.
•Keep the board and all electrical
components clean of dirt, paint,
and moisture.
•To clean the board use canned air. If a
more aggressive cleaning method is needed
lightly scrub the components with a soft,
dry brush. Heavy scrubbing will damage
the board.
WARNING
TURNING THE DM4 ON AND OFF
To turn on the DM4 press and hold the power button (see figure 1) until the LED light turns blue. The blue light indicates
board bootup. After the bootup sequence, the LED will turn either RED (no ball) or GREEN (ball ready to fire). To turn the DM4
off press and hold the power button until the LED turns off.
NOTE: The DM4 automatically switches off after 10 minutes of non-use.
FIRING THE DM4
As soon as the marker is turned on and the LED turns from blue to either red or green, the DM4 is ready to fire. If there is no
ball and the LED is RED, you need to hold the trigger for 1 second to force the DM4 to fire once. If there is paint inside the
breech and the LED is green, just press the trigger to fire the marker.
LED LIGHT INDICATOR
There is a super high intensity LED light mounted on the board behind the DM4 logo on the left side of the grip panels. This
light provides information to the user by the DM4. There are three colors on the LED light. Red, green and blue.
When you turn on the marker in normal operation mode with the power button, the light colors mean the following:
Blue Bootup sequence.
Red No ball detected inside the DM4 (eye on)
Green Ball detected inside the DM4 (eye on)
Blinking Red Eye function turned off, The DM4 will fire even though there is no ball inside the breech.
Blinking Green Eye blocked. This means that your eyes are either dirty or there is a bad connection.
The ROF (rate of fire) is automatically reduced to prevent chopping.
If this happens during game play, you can turn the eye off to increase your ROF.
NOTE: The eye is always activated when you turn the marker on.
BLUE GREENRED
BOARD SETTINGS AND CONFIGURATION MODE
There are five settings you can alter on the DM4 board with the DIP switches inside the grip frame (see figure 1):
ABS Anti Bolt Stick.
Eye sensitivity This setting changes how long the eye waits for the ball to set into the breech.
Trigger sensitivity This setting adjusts the delay between two trigger pulls.
Dwell This is the time the solenoid is activated for.
ROF Rate Of Fire when the eye is deactivated.
Anti Bolt Stick - When ABS is activated, the dwell is increased after 15 seconds of non-use for the next shot fired.
This helps to prevent bolt-stick, but may result in higher velocity for the first shot.
ABS on ABS off
(default)
Eye Sensitivity - The eye sensitivity setting determines the time that is needed to allow the next ball to settle
into the breech. Too sensitive an eye setting may result in chopping and too high a setting limits
the maximum ROF that can be achieved. Optimal sensitivity setting varies between different
paintball brands and the loader used. There are 4 different settings available. These settings can
be achieved using DIP switches 2 and 3.
FASTEST AVERAGE SLOWEST
Setting 1 Setting 2 (default) Setting 3 Setting 4
DIP 2 - off DIP 2 - off DIP 2 - on DIP 2 - on
DIP 3 - off DIP 3 - on DIP 3 - off DIP 3 - on
The most sensitive and fastest setting is 1; this should only be used with force feed loaders such as a HALO™.
The middle two settings are good for other agitated loaders. Setting 4 is for slower loaders.
