HYPER
2
IN-LINE REGULATOR
- Adjustments and Maintenance.
• The Hyper
2
can hold a small residual charge
of gas, typically 2 shots. Always discharge
the marker in a safe direction to relieve this
residual gas pressure.
• Always remove the regulator from the
DM4 before servicing.
• Improper stacking of shims will cause
failure of the regulator and possible
damage to the DM4.
• Excessive dirt and debris can affect
the Hyper
2
’s performance and increase
the need for servicing.

USAGE
Carefully connect your air hose from your bottle or air system to the Hyper
2
In-Line. The Hyper
2
In-Line is set by the factory to
approximately 170psi. This pressure should give you a velocity of approximately 285fps.
ADJUSTMENTS
The output pressure of the Hyper
2
In-Line is adjusted by turning the brass seat housing. The seat housing screw is located up
inside the bottom of the reg. A 3/16” Allen wrench will be needed for this operation. By turning the housing counter-
clockwise, you will increase the output pressure of the reg to the marker. By turning the housing clockwise, you will decrease
the output pressure of the reg.
After each adjustment of the output pressure of the Hyper
2
In-Line, you will need to cycle your marker a few times. This will
allow your marker and air system to stabilize at their new operating pressure. The Hyper
2
will need a break-in period of about
2,500 shots to let its seat form to the piston and reach its optimum performance.
The Hyper

has nine components

Disassembly of the Hyper
2
In-Line is easily done with 3/8” and 5/16” Allen wrenches.
MAINTENANCE
To ensure top performance from the Hyper
2,
maintenance should be performed every four months, or sooner, depending on
the severity of playing conditions. Cold, wet weather will shorten the effective life of the grease. Heavy dust or fine sand can
infiltrate the Hyper
2
and prevent the piston from moving smoothly and or cut the o-rings.
1
Make sure the inlet and outlet ports and connecting fittings are free of all dirt and paint.
2
Examine all o-rings for nicks or cuts.
3
Carefully inspect the seat for excessive wear that might cause spiking and over-pressurizing.
4
Clean any accumulated dirt out of the air chambers and passages.
5
Keep the piston o-rings and spring pack generously greased to allow smooth velocity adjustment and prevent
erratic velocity spikes and drop off.
6
Clean off all old grease that may be contaminated with dirt; reapply fresh grease to the piston and other necessary areas.
7
Be sure to reassemble the internal components and shim stack
(see figure 2)
in the proper order and direction.

ANTI CHOP EYES
The Anti Chop Eye (ACE) system will prevent the DM4 from chopping paint by not allowing the marker to fire until a ball is
fully seated in front of the bolt. The eyes use a beam across the breech. On one side there is a transmitter, and on the
opposite side a receiver. In order for the marker to fire with the eyes turned on, the signal between the two eyes must be
broken. After every shot, before the next ball drops in the breech, the eye transmitter and receiver must see each other. If the
eyes are dirty and cannot see each other between shots, the LED on the board will start blinking green. This means that the
eyes are dirty. This is an extremely reliable system as long as the eyes are kept clean. The most common reason for dirty eyes is
broken paint. If the eyes become dirty the marker will default to a reduced rate of fire to prevent chopping. If this happens
during game play you can bypass this by turning the eyes off. Clean the eyes as soon as possible.
NOTE: IF THE BATTERY IS LOW, THE MARKER MAY ACT AS IF THE EYES ARE DIRTY OR
NOT FIRE AT ALL. IN THIS CASE, REPLACE THE BATTERY.
CLEANING THE ANTI CHOP EYES
Quite often just cleaning the breech out with a swab will clean the eyes well enough for them to read one another.
For a thorough cleaning, the best method is to use air. Using an air hose or canned air (typically used for dusting keyboards) works best.
Blow the eyes clean from inside the breech. If you feel the eyes still need a more detailed cleaning, remove the eye covers to gain full
access to the eyes.
To remove the eye covers you will need a 1/16” Allen wrench [.050” Allen for the first runoff DM4’s]. Simply insert the Allen wrench into
the hole in the eye cover to access the retaining screw
[see figure 1]
. As you back the screw out, the plate will be pushed up.
NOTE:Regular eye cleaning is recommended even if no paint is broken. Clean the eyes every two months or 10,000 shots to eliminate any built
up of dirt. Excess grease from the front bolt o-ring can build up in front of the eyes. Remember to check for this after greasing the bolt and
cycling the gun a few times.
ANTI CHOP EYE/BALL DETENTS
- Maintenance and Changing.
CHANGING BALL DETENTS
The ball detents are also located under the eye covers. If you are experiencing double feeding or chopping, check the
condition of the ball detents. They should come to a soft point. If they are flat or heavily rounded they should be replaced.
Ball detents should be replaced about every 40,000 shots.
NOTE: TAKE CARE WHEN REPLACING THE EYE COVERS. OVER-TIGHTENING THE
RETAINING SCREW COULD RESULT IN STRIPPING THE THREADS.
