WARNING
IMPORTANT SAFETY INSTRUCTIONS AND GUIDELINES!
1. The DP G4 is NOT A TOY. Treat it with the same
respect and care you would a rearm.
2. Carelessness, Misuse, and failure to adhere
to the warning and guidelines printed in this
Owner’s Manual may result in property damage,
injury, or death. User assumes all risks
associated with use of the DP G4.
3. Always ensure that proper safety gear - eyes,
face, ear, and head protection - conforming to
ASTM standard F1776 (USA) or CE (Europe)
are worn at all times when paintballs are within
range.
4. Persons under the age of 18 must have adult
supervision at all times during use of the G4, or
any paintball ring device.
5. Observe all local and national laws regarding
rules and regulations.
6. The G4 should only be used on a permitted and
regulated paintball eld where safety rules and
guidelines are strictly enforced.

W W W . D A N G E R O U S P O W E R . C O M
7. Only use compressed air or nitrogen. DO NOT
USE CO2!
8. Only use high quality, .68 caliber paintballs.
9. Never point your G4 at an unintended target.
10. Always treat your G4 as if it were loaded.
11. Keep your G4 turned OFF until ready to use.
12. Always measure the velocity of paintballs from
your G4 with a suitable chronograph device
before play.
13. Never look down the barrel or breech area of
the G4 without rst ensuring that the marker is
switched to the OFF position, with NO AIR in the
marker.
NOTE- SEE NOTE ON PAGE 3 FOR DIRECTIONS ON
REMOVING RESIDUAL AIR FROM A POWERED ‘OFF”
MARKER.
14. Never put any body parts or foreign objects into
the breech or feed tube.
15. Always use the supplied barrel cover when your
G4 is not in use at the eld. Doing so will help
secure the safety of yourself and those around
you.
16. Never allow pressurized gas to come into
contact with your body. Serious harm, injury, or
death may occur.
17. When not in use, always turn your G4 to the
OFF position.
18. Promptly remove any paintballs from your G4
when not in use.
19. Always remember to remove residual air from
your G4 before attempting maintenance or
service.
20. Always remember to remove residual air from
your G4 before storage or transportation.
NOTE- POWERING ‘ OFF’ THE MARKER WILL NOT
AUTOMATICALLY REMOVE RESIDUAL AIR. TO
SAFELY REMOVE RESIDUAL AIR, PLEASE DO THE
FOLLOWING:
A. Remove loader and paintballs from marker.
B. Turn Eye Sensors to the OFF position.
C. Point marker in a safe direction.
D. Fire marker until all residual gas is removed.
21. Always store your G4 in a safe place.
22. Do not discard the Owner’s Manual. In the event
of transfer or resale, this guide must accompany
the marker.
23. When in doubt, ALWAYS seek expert advice
by contacting a reputable airsmith familiar with
paintball markers, or by contacting
DP Engineering’s Customer Service Staff.

• There are four adjustment screws (marked A, B, C and D) to adjust the trigger on the G4.
• Screw A (5/64”) adjusts the amount of trigger travel prior to the marker ring. Turning this screw clockwise will
reduce the amount of trigger travel. Turning this screw counterclockwise will increase the amount of trigger
travel. (SEE PIC A)

IMPORTANT NOTES BEFORE SERVICING YOUR MARKER :
• DP ENGINEER SUGGEST YOU ALWAYS USE DP-40 LUBE TO SERVICE YOUR MARKER.
• DO NOT APPLY EXCESSIVE LUBRICANT.
• ALWAYS INSPECT AND CLEAN YOUR MARKER AFTER EACH USE.
• NEVER APPLY EXCESSIVE FORCE WHEN REMOVING OR REPLACING SCREWS. DOING SO MAY
STRIP THE SCREW HEADS OR DAMAGE THREADS.
• ALWAYS USE THE CORRECT SIZE AND THE APPROPRIATE TOOLS.
• REFRAIN FROM SUBMERSING ENTIRE MARKER IN LIQUID. KEEP SENSITIVE ELECTRONICS
SUCH AS SOLENOID AND CIRCUIT BOARD FREE FROM MOISTURE.
• NEVER ALLOW SOMEONE WHO IS UNFAMILIAR WITH YOUR MARKER TO PERFORM
MAINTENANCE OR REPAIR WORK. WHEN IN DOUBT, CONTACT DP ENGINEERING CUSTOMER
SERVICE.
CLEANING THE EYE-SENSOR BREAK BEAM SYSTEM
The function of the break beam sensor eyes is to allow the ring circuit to ‘time’ the activation of the solenoid. This
prevents ‘chopping’ of paint, which is caused by the bolt cycling within the breech without the paintball being
actually seated in the proper ring position. When the eye sensors are ON, the gun will not re if the beam does
not sense a paintball. To ensure proper function, the eye sensors should be cleaned after every other use, or when
paintballs have been broken within the marker. More frequent cleaning may be necessary when using paintballs
that have ‘oily residue’ on the surface of the shell. To avoid malfunction, always use fresh and clean paint from a
reliable manufacturer.
To clean the eyes:
1. Locate the eye cover plates on either side of your G4 body. (SEE PIC A)
2. Using provided allen key wrench (5/64”), carefully remove the eye cover screw on one side by inserting ball
point tip and turning wrench handle counterclockwise. (SEE PIC B)
3. Lift eye cover plate, exposing eye wires, spring, and ball detent. (SEE PIC C)

4. Carefully lift eye wires and pull out the eye sensors from the socket. Be careful not to lose the spring and the
ball detent. (SEE PIC D)
5. With a cotton swab, gently wipe the back and front side of the eye sensor and the eye socket to remove any
debris or residue. (SEE PIC E)
6. Replace eye sensors back to original position. Be sure the eyes are aligned correctly and facing the direction
of the breech.
7. Replace eye cover plate in original position and gently tighten eye cover screws clockwise. DO NOT OVERTIGHTEN! (SEE PIC F)
8. Repeat the same procedure on the other side.
HELPFUL HINT
DO NOT PULL ON THE EYE WIRES. USE A SMALL PICK OR SCREW DRIVER TO GENTLY LIFT THE
WIRES UP. THIS WILL LIFT THE EYE SENSORS OUT OF THE EYE SOCKET.
CLEANING THE BALL DETENTS
The ball detents and spring should be inspected during the cleaning of the eye sensors. Replace these parts
should you notice any damage, no matter how slight.
1. Locate the eye cover plates on either side of your G4 body.
2. Using provided allen key wrench (5/64”), carefully remove the eye cover screw on one side by inserting ball
point tip and turning wrench handle counterclockwise. (SEE PIC A)
3. Lift eye cover plate, exposing eye wires, spring, and ball detent. (SEE PIC B)

OPERATING PRESSURE REGULATOR (OPR)
DISASSEMBLY AND MAINTENANCE
The OPR regulates the amount of air-ow, which determines paintball velocity. Regular inspection and cleaning of
your OPR is an essential part of keeping your G4 running in top condition. Follow the easy steps outlined below to
ensure that your OPR remains trouble-free.
7. With a cotton swab, clean the spring, ball detent, and detent groove. (SEE PIC E)
8. Replace detent back to original position, with the circular side down towards the breech.
9. Replace spring over the detent in the original position.
