QUICK REFERENCE

USING YOUR MARKER

QUICK START UP GUIDE

Before playing with your new RAIL™ paintball marker there are a few

important steps to take.

STEP 1. BATTERY INSTALLATION

A. Remove three right hand side grip panel screws with a 3/32” allen key.

B. Open grip panel and install 9V battery into the connector inside the frame.

C. Close grip panel and tighten the three screws back. While closing the panel

observe that no wires get caught between the frame and the grip panel.

STEP 2. BARREL INSTALLATION

A. Screw on the barrel to the front of the RAIL™. Make sure it threads all the

way in and tightens good.

B. Attach the barrel sock so that it covers the tip of the barrel and secure the

strap around the back of the RAIL™.

STEP 3. LOADER INSTALLATION

A. Use the thumbscrew to tighten your loader into the adjustable feedneck on

the RAIL™. For best performance you need a force feeding motorized loader,

preferably the Rotor™ Loader. Loader should now be held in with a snug fit.

QUICK REFERENCE

USING YOUR MARKER

STEP 4. ATTACHING GAS SOURCE

A. Screw in your air system to the ON/OFF airport and turn the knob of the

airport clockwise, all the way in.

STEP 5. TURNING ON THE RAIL™ AND CHECKING THE VELOCITY

A. Make sure you and everybody around you is wearing ASTM / CE approved

paintball masks.

B. Press and hold the top button located behind the grip frame until the

RAIL™ turns on. WARNING, the RAIL™ is LIVE. Make sure barrel sock is in place

and do not point the RAIL™ at anything you don’t intend to shoot.

C. Fill up the loader with .68 caliber paintballs.

D. Shoot the RAIL™ over a chronograph to check the velocity. If adjustment is

needed, adjust the velocity by turning the Hyper3™ velocity adjustment screw

with a 3/16” allen key. In (clockwise) will reduce the velocity and out (counter

clockwise) will increase the velocity. After each adjustment it takes a few

shots before the change can be seen on the chronograph. Never adjust the

RAIL™ to shoot faster than 300fps or what the field rules / local laws permit.

SETTINGS AND FUNCTIONS

TURNING THE RAIL™ ON AND OFF

To turn on the RAIL™, press and hold the power button until
the LED’s turn blue. The blue light indicates board boot up.
After the boot up sequence, the LED’s will turn either RED
(no ball) or GREEN (ball ready to fire). To turn the RAIL™ off,
press and hold the power button until the LED’s turn off.

NOTE: The RAIL™ automatically switches off after 10
minutes of non-use.

FIRING THE RAIL™

As soon as the marker is turned on and the LED’s turn from
blue to either red or green, the RAIL™ is ready to fire. If there
is no ball and the LED’s are RED, you need to hold the
trigger for 1 second to force the RAIL™ to fire once. If there is
a paintball inside the breech and the LED is green, just press
the trigger to fire the marker.

LED LIGHT INDICATOR

The RAIL™ uses two super bright LED’s mounted on the circuit
board inside the grip frame. These two lights are used to
provide information to the user about the RAIL™. They will
always show the same information and it does not matter
which LED you look at. One is mounted behind the RAIL™ logo
on the left side of the grip panel. The other one can be seen
by looking at the top left side of the grip frame while holding
the RAIL™ in the position you would while playing a game.

6 7

When you turn on the marker in normal operation mode with the power button, the light colors
mean the following:

Blue - Boot sequence

Red - Breech is clear, no ball detected inside the RAIL™ (eye is on)

Green - Ball in breech, ready to fire (eye on)

Blinking Red - Eye is turned off
Blinking Green - Eye failure, eye is blocked or dirty (see RAIL™ Eye, page 26)
Blinking Blue - Indicates a low battery; battery should be changed as soon as possible

NOTE: The eye is always activated when you turn the marker on.

To turn off the eye feature press and hold the bottom button until the LED light starts blinking
Red indicating the eye feature is turned off.

When servicing your marker:

• Make sure a barrel sock is fitted to the RAIL™.

• Make sure your hopper is removed from the RAIL™.

• Make sure there are no paintballs in the breech of the RAIL™.

• Always remove the first stage regulator and relieve all residual gas
pressure from the RAIL™ before disassembly.

• The RAIL™ 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.

Configuration Mode - The following settings can only be

modified in configuration mode. To activate the configuration
mode, turn your marker off and set DIP switch 2 to the ON
position. Next, turn your marker on. The LED's cycle through
all colors for one second to indicate that you have entered
the configuration mode.

To cycle through different settings, pull and release the trigger.
Configuration mode has 4 settings that can be changed.

TO CHANGE A VALUE OF A SETTING

1. While in the configuration mode, choose the color you wish to change by pulling the trigger.

2. When the LED indicates the color you wish to change, pull and hold the trigger until the LED
starts to flash.

3. The LED will flash as many times as the previous setting was and it will then turn off. Now pull
the trigger as many times as you wish the new setting to be.

4. When done, the LED will cycle through all the colors again to indicate setting was saved and
turn back to green. You can now change another setting or quit the configuration mode.

5. To exit configuration mode, set DIP 2 to the OFF position.

• The RAIL™ 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.

SETTINGS AND FUNCTIONS

Green - Trigger Sensitivity Values 1 - 20 (factory default 5)

Trigger sensitivity is the amount of time that the trigger has to be
released before the next trigger pull is allowed. In some situations
with too low of a value, the RAIL™ can register more trigger pulls
than what was actually pulled. This can cause the RAIL™ to shoot full
auto, even in semi-automatic mode. To fix this, adjust the trigger
sensitivity setting higher.

Red - Dwell Values 1 - 30 (factory default 18)

Dwell is the amount of time that the solenoid will be activated.

Follow these steps for the best way to set your dwell:

• Remove loader and any paintballs from the RAIL™ marker.

• With the dwell set at 10, start increasing the value until the marker
begins to fire.

• When you reach the setting where the marker begins to fire, get
some paint and a loader and go to a chronograph.

• Increase the dwell until you see no increase in the velocity.
This is the optimal dwell setting to be used.

NOTE: You cannot turn your marker off with the power button
when the marker is in configuration mode. You must first set DIP
switch 2 to the OFF position.

The ROF setting is used to set the maximum rate of fire of the RAIL™.
The values do not correspond directly to a certain Balls Per Second
(BPS) value. You will need to use the table below to locate your
desired maximum ROF setting.
The factory setting is 20 (12.5 bps).

Increasing ROF too high will increase probability of ball breakage.
If this occurs decrease ROF setting.

This setting changes the firing mode of the RAIL™. Default is
semiautomatic. In the semiautomatic mode, one trigger pull
shoots out one paintball. The PSP mode and the Millennium

BATTERY

The 9V battery will last for about 40,000 shots. Please be aware that there are substantial
differences in performance between different brands of batteries. Use of high quality alkaline or
lithium ion batteries is recommended for maximum battery life. If you plan not to use your marker
for a long period of time (a month), it is recommended that you remove the battery from the
marker. When the battery voltage starts to go too low, the marker will not fire with every trigger
pull. For tournament use, it is recommended to change the battery for each tournament.

CHANGING THE BATTERY

The battery is housed on the right side of the grip frame. To access the battery, remove the three
screws holding the right side grip panel down. Use a
notice the + and - marks on the board. The positive lead of the 9V battery goes to the left and the
negative lead to the right.

NOTE: If the marker will not function with the eye on, there is a good chance the battery needs
to be changed.

• A low battery will not be able to power both the ACE eye and the trigger
switch, causing ACE eye failure.

• If the battery is low, the marker will not fire with every trigger pull.

ADJUSTING YOUR TRIGGER

The trigger’s forward travel, over
travel and spring tension are fully
adjustable so that the user can
fine-tune the trigger to his or her
exact liking. You do not need to
remove the frame from the gun
in order to adjust the trigger pull.

There is one adjustment screw
located on the right side of the
Ultralite frame behind the sticky
grip, one adjustment screw
located in the top of the trigger,
and one adjustment screw
behind the trigger.
The adjustment screw on the
right side of the frame adjusts
the over travel of the trigger.
The adjustment screw in the top
of the trigger adjusts the forward
travel of the trigger. The screw
located behind the trigger is
used to change the tension of
the trigger spring.

14 15

TO ADJUST TRIGGER TRAVEL (SEE FIGURE 1)

• The screw in the top of the trigger (1 ) controls the forward travel.
Screwing it in will shorten the trigger’s length of pull.
Use a .50” allen key to adjust this screw.

NOTE: If this screw is adjusted too far, the switch will be held down at all times and the marker
will not fire.

• The screw on the right side of the frame ( 2) controls the over travel. By turning this screw
you can adjust how far the trigger will travel after it reaches the firing point.
Use a 5⁄64” allen key to make the desired adjustment.

NOTE: If this screw is adjusted too far, the trigger will not be allowed to travel far enough to
depress the switch and fire the marker.

TO ADJUST SPRING TENSION (SEE FIGURE 1)

• The adjustment is made by pushing the allen key through a hole in the trigger (3).
Use a 5⁄64” allen key to make the desired adjustment.
To make the trigger pull stiffer, turn the allen key clockwise or in.
To make the trigger pull lighter, turn the allen key counterclockwise or out.

• Be sure the trigger is not adjusted to the point where it is too sensitive

and may cause accidental discharge of the marker.

• Removing the trigger spring will cause premature wear on the microswitch,

resulting in failure.

• Be sure you do not pinch the wires between the frame and body when

reattaching the frame to the body.

RAIL™BOLT

ASSEMBLY AND MAINTENANCE

RAIL™BOLT

ASSEMBLY AND MAINTENANCE

BOLT SAIL

CAN BOLT MANIFOLD BACK CAP

The RAIL™ BOLT is the main component of the RAIL™ marker. In order to achieve the best
possible performance of the RAIL™ it is essential that the RAIL™ BOLT is kept clean, well lubed
and in good working order.

The RAIL™ BOLT should be cleaned and re-lubed every 10,000 shots or after breaking paint or
playing in severe conditions.

There are 4 parts in the RAIL™ BOLT kit that mount together as one unit. To remove the RAIL™
BOLT from your RAIL™, use a 1/4" allen key and turn the Back Cap out 1
the complete RAIL™ bolt kit from the RAIL™.

To dis-assemble you unthread the front most part called the Can and the Manifold from each
other. Then pull out the actual moving bolt from inside
these pieces. Notice that to remove the Can you need
to remove the bolt tip O-ring before the bolt is able to
slide through the Can.

HOW DOES IT WORK

Air is supplied into two points on the RAIL™ BOLT. In the
back air is routed through the Manifold and fills up the
supply chamber around the Manifold. In the front air is
routed through the solenoid into the Can. This air pushes
against the Sail on the Bolt which keeps the bolt in the back position.

1

⁄2 - 2 turns. Now pull out

FORWARD POSITION

BACK POSITION

When the RAIL™ is fired the solenoid is actuated
and the air inside the Can is exhausted out. This
causes the Bolt to start moving forward with the
force created by the air inside the supply
chamber. Once the bolt has moved about half way
forward, the input into the supply chamber is
closed and a patent pending Boost™ feature is
activated on the Back. This gives the Bolt an extra
push forward and makes sure the valve of the
RAIL™ is opened fast and efficiently. The
secondary benefit of this Boost™ feature is that on
the initial part of the Bolt movement, the Bolt
pushes very gently against the paintball inside the
breech reducing ball breakage.

Once the Bolt reaches the forward point, the valve of the RAIL™ Bolt is opened and air inside the
supply chamber goes through the Bolt and fires the paintball. After this the solenoid is de­activated and gas is supplied through the solenoid back into the Can. This causes the Bolt to return
to the back position and the supply chamber to be re-charged. Notice that when the Bolt moves to
the back position a small amount of gas used for the Boost™ feature is leaked out through the
Back Cap.

When servicing your marker:

• Make sure your hopper is removed from the marker.

• Make sure there are no paintballs in the breech of the marker.

• Always remove the air supply and relieve all gas pressure in the marker

before disassembly.

• When using the marker in temperatures below 50° Fahrenheit it may be

necessary to lube the RAIL™ bolt more frequently.

ASSEMBLY AND MAINTENANCE

RAIL™BOLT

ASSEMBLY AND MAINTENANCE

MAINTENANCE

The basic maintenance for the RAIL™ BOLT is to
clean all surfaces of dirt, broken paint or
other debris, check for any wear and
tear on the O-rings and changing them
if needed, and finally applying a thin
coat of DYE Slick Lube on all
surfaces. Before installing the RAIL™
BOLT back to the RAIL™ marker check
that the bolt moves freely without a lot of
friction.

Before installing the RAIL™ BOLT back into the RAIL™ make sure all pieces are threaded together
snugly!

If the RAIL™ BOLT is not kept clean and well lubed, you will either start seeing erratic velocity,
leaks or over long period of time, physical damage to the RAIL™ BOLT components.

Notice that it’s normal for a small amount of gas to come out through the back cap when the
RAIL™ is fired. This gas is used for the Patented Boost™ forward technology of the RAIL™.

For troubleshooting leaks and other bolt problems, consult the troubleshooting section at the end
of this manual.

LOADERS AND FEED NECK

AIR/NITROGEN

LOADERS AND FEED NECK

To achieve the maximum performance
of the RAIL™ you will need to use a
motorized loader that force feeds
paintballs into the RAIL™ marker,
preferably the Rotor™ Loader. Using a
slower motorized loader or a non­motorized loader will work,
but the rate of fire and performance
will be reduced.

To fit a loader onto the RAIL™:

1. Loosen the feed neck adjustment
thumb screw.

2. Push the loader all the way into the
feed neck.

3. Tighten the feed neck adjustment
screw until loader is secure. Note that
using too much force tightening the
screw could cause damage to your
loader.

Loader should now be held in with a
snug fit.

There is no maintenance needed for
the feed neck besides keeping it clean
of broken paint, dirt and debris.

AIR / NITROGEN TANK OPTIONS AND INSTALLATION

The RAIL™ will only work with Compressed air or Nitrogen
air systems such as the DYE Throttle air system. Do not

use CO2or any other compressed gas. The

output pressure from the air system has to be

between 400 – 850psi.

To install an air system, screw the tank

into the airport all the way as far as it

will go. To remove the air system

screw out. There will be gas leaking

for a few seconds while you screw

the air system out. Notice that

even with the air system

removed there can be gas

inside the RAIL™ and it can

still fire a paintball. Always

treat the marker as being
live and never point it to
anything you don’t intend
to shoot at!

HYPER3™ IN-LINE REGULATOR

ADJUSTMENTS AND MAINTENANCE

HYPER3™ IN-LINE REGULATOR

ADJUSTMENTS AND MAINTENANCE

VELOCITY ADJUSTMENT

The velocity of the RAIL™ is adjusted by adjusting the input
pressure into the RAIL™. This is controlled with the Hyper3™
regulator. The Hyper3™ on the RAIL™ is factory set to 145 psi which

will give you a velocity of about 285 FPS (Feet per Second).

3

A

⁄16” allen key will be needed for this operation. Turning the

adjustment screw in (clockwise) will decrease the pressure, and out

(counterclockwise) will increase the pressure. To adjust the velocity:

1. Make sure you and everybody around you is wearing
ASTM/CE approved paintball goggles.

2. Shoot the RAIL™ over a paintball chronograph.

3. To lower the velocity turn the Hyper3™ adjustment screw in.

To increase the velocity turn the screw out. Only turn the screw

a quarter turn at a time and shoot over the chronograph again.
Notice that a few shots are needed before the change can be
seen on the chronograph.

MAINTENANCE

For the RAIL™ to function properly, it is essential that the input
pressure into the marker stays consistent at all times. The general
maintenance needed for the Hyper3™ regulator is to keep it clean
of dirt and debris at all times. A more extensive service should be
performed every 12 months by a trained Tech or if the output
pressure of the regulator doesn’t stay consistent. This can be seen
as inconsistent velocity and verified with a regulator tester (sold
separately). Notice that the Hyper3™ has a break in period of
about 2000 shots before it achieves the best performance.

24 25

HYPER3™ REGULATOR DIS-ASSEMBLY INSTRUCTIONS

To disassemble the Hyper3™ regulator you will need a3⁄16” allen key and a5⁄16” allen key. Place the

3

⁄16” allen key inside the top cap and the5⁄16” allen key inside the bottom cap. Unscrew the bottom

cap from the Hyper3 body.

Next unscrew the brass seat housing from the body with a
body.

To change the seat, pull out the old seat from the housing with a sharp object. Insert the new seat
in place and push it down with a flat object. Notice that it takes about 2000 shots for the seat to
perfectly sit into the seat housing. This is called the break in period for the regulator.

Remember to apply lube to the 010 and 013’s in the regulator before re-assembly.

Further disassembly to service the top section of the Hyper3™ should be performed by
a trained Tech.

ANTI CHOP EYES/ BALL DETENTS

MAINTENANCE AND CHANGING

ANTI CHOP EYES/ BALL DETENTS

MAINTENANCE AND CHANGING

ANTI CHOP EYES

The Anti Chop Eye (ACE)
system will prevent the RAIL™
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.

26 27

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 cover to gain full access to the eyes.

To remove the eye cover, you will need a 1/16” allen key, take caution not to loose the detent
spring when removing the eyeplate.

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 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 marker a few times.

CHANGING BALL DETENTS

The ball detent system is also located under the eye covers. The ball detent system needs little or
no maintenance. There is a spring behind each detent, which holds the detent forward. This spring
pressure should be easily overcome with very little force, such as a paintball moving past. If you
are experiencing double feeding or chopping, check the condition of your ball detents with your
finger to make sure they are not stuck in the up or down position and that they move in and out
of the breech freely. If excessive broken paint or dirt has jammed your ball detents, remove the
eye plates (being careful not to lose the detent springs) and pull the detents out for a thorough
cleaning. Reinstall the detents, springs and eye covers after you have sufficiently cleaned the
detents and breech.

NOTE: TAKE CARE WHEN REPLACING THE EYE COVER. OVER-TIGHTENING THE RETAINING
SCREW COULD RESULT IN STRIPPING THE THREADS.

TROUBLE SHOOTING GUIDE

AIR LEAKS

AIR LEAKING FROM THE AIRPORT

• Check the o-ring on the air system. If needed
change the O-ring and try again. The O-ring
normally used is #15 but some manufacturers
might use a different size. Consult the manual
of the air system you are using.

• Check that the hose connector is tight.
Remove the hose from the connector by
pushing the floating ring towards the
connector and pull out hose.
Use a 7/16” allen key to tighten. If needed
remove and apply thread sealant to the thread
and re-tighten. If unsure consult expert advice.

• Check that the end of the hose is cut straight
and is not worn out. If needed cut a small piece
off the hose with a razor blade and re-insert
hose into the fitting.
Make sure hose goes all the way to the end.

AIR LEAKING FROM THE HYPER3™ REGULATOR

• First locate the position of the leak.

• For disassembly instructions consult the
technical section under Hyper3™ regulator.

• If the leak is coming from the bottom of the
regulator you will need to disassemble the
regulator and change the #010 O-ring and
the seat on the brass seat retainer mounted
inside the Hyper3™ regulator.

• If the leak is coming from the swivel piece

where the hose connector mounts, you will
need to change the two #013 O-rings under
the swivel piece or tighten the hose connector.

• If the leak comes from the small hole in the
middle of the regulator there are two possible
O-rings. Change the #015 O-ring on the
piston and the #007 urethane O-ring inside
the body of the regulator.

• If the leak is from the top of the regulator
change the #012 O-ring on the outside
of the cap.

AIR LEAKING FROM THE ASA

• First make sure that the ASA is tightened well
into the body of the RAIL™ by removing the
Hyper3™ regulator and tightening the ASA
with a 3/16” allen key.

• Next change the #012 O-ring on the top cap of
the Hyper3™ and apply a small amount of lube
to the O-ring.

• Finally, if above steps don’t help, remove the
ASA with a 3/16” allen key and change the
#012 O-ring mounted on the top of the ASA.
Apply a small amount of lube and tighten
back together.

AIR LEAKING BETWEEN BODY AND FRAME

• A leak between the body and the frame can be
caused by a couple of things.

• First pull out the Bolt kit and change the #015
sail O-ring and the three #020 O-rings on the
outside of the Can.

28 29

• If above doesn’t help, remove the frame from
the RAIL™ and remove the solenoid by
unscrewing the two screws mounting it down.
Apply some lube to the seat underneath the
solenoid and re-assemble making sure that the
solenoid is well tightened into the body and
that the eye wire is not pinched underneath
the solenoid.

• Last possibility is that one of the gas passages
is leaking. Gas up the RAIL™ without the frame
attached and try to locate the exact point of
leakage. If the leak is coming from one of the
blocked holes remove the screw, apply some
thread sealant and re-attach screw to the body.

AIR LEAKING FROM BACK OF THE RAIL™

• Check that the bolt kit is tightened all the way
into the RAIL™. If the bolt kit is loose, it will
start to leak.

• If above does not solve the leak, remove the
bolt kit and change the #020 O-ring on the
back part of the bolt. Also change the two
#009 O-rings located in the stem of the bolt.
Lube well and re-insert the bolt kit into the
RAIL™. Check bolt kit break down picture on
page 19 for O-ring locations

• Last, check that the gas passage blocking
screw located on the right side of the RAIL™ is
not leaking. If the leak is coming from this hole,
remove screw and apply thread sealant to it.
Make sure to tighten the screw well and wait
for sealant to dry before re-gassing marker.

TROUBLE SHOOTING GUIDE

AIR LEAKING FROM FRONT OF THE RAIL™

• Remove the Bolt kit from the marker and
change the #017 O-ring located inside
of the Can and the #014 O-ring located inside
the Manifold. Lube well and re-assemble.

• If above doesn’t help, try changing the #020
O-rings located outside of the Can.
Lube well before re-inserting bolt kit.

PROBLEMS WITH ELECTRONICS

RAIL™ WON’T TURN ON

• Make sure battery is new and well charged.

• Check that battery is connected to the 9V clip
inside the RAIL™ .

• Make sure there is no dirt or debris blocking
the button from being pressed.

RAIL™ WILL TURN ON / OFF BY ITSELF OR THE
EYES WILL TURN ON / OFF BY THEM SELVES

• Both of these problems are caused because
the button(s) are pressed all the time.

• Remove board from the frame by removing the
grip panel on the left hand side, disconnecting
the cables and pulling the board out. Carefully
remove the two buttons and clean them well.

• Re-assemble and test. If problems persist,
contact authorized service center for board
replacement.

TROUBLE SHOOTING GUIDE

EYES WILL NOT WORK, LED KEEPS
BLINKING GREEN

• First change the battery. The eyes are normally
the first thing to stop working when a battery
is dying.

• Next try to clean the eyes. You can either use
canned air and blow out the eye holes through
the feed neck hole. Or remove the eye plates
with a 1/16” allen key, pull out the eyes from the
mounting holes carefully and clean them with
q-tips. To test if the eyes work make sure there
is nothing inside the breech and that the bolt is
in the back position. Turn on the RAIL™, the
light should be red after the boot up sequence.
If it is, the eyes are working.

• Check that the eye wire is connected to the
board so that metal clips are facing down.

• If nothing above helps contact a store or DYE
Precision for eye replacement.

SOLENOID WILL NOT ACTIVATE / TRIGGER
NOT WORKING

• Check that the trigger adjustment is not set so
that the micro switch cannot activate.
You should hear a small click when pulling
the trigger.

• If the RAIL™ fires once when turned on but not
after that your trigger is set so that the micro
switch is always activated. Re-adjust the trigger.

• If the trigger is correctly adjusted but the
RAIL™ still won’t fire, check that the micro

switch cable is well inserted into the board and
to the correct connector (the micro switch
connector is marked with the text “SWI” on
the board).

• Change the battery if not positive about it’s
charge.

• Check that the solenoid cable is attached to
the board and to the right connector (solenoid
should be attached to the connector that is
marked with the text “SOL”).

TRIGGER BOUNCE / RAIL™ SHOOTING MORE
THAN ONE BALL PER PULL IN SEMI AUTOMATIC
MODE

• Raise the trigger sensitivity level in the
configuration mode.

• Check that the trigger is not adjusted too
short.

• Make sure there is a trigger spring inside
the frame.

ERRATIC VELOCITY/RAIL™ WON’T FIRE

RAIL™ FIRES BUT BALLS ARE DROPPING OFF
OR NOT EVEN COMING OUT OF THE BARREL

• Make sure the battery is good.

• Raise the dwell to factory level (18).

• Make sure bolt is well lubed and moves well.
If there is too much friction in the Bolt, it will
cause the RAIL™ to shoot down.

• Make sure air system is screwed in all the way.

TROUBLE SHOOTING GUIDE

FIRST SHOT IS TOO HIGH

• Change the Seat inside the Hyper3™ regulator.
For disassembly instructions consult the
technical section.

• Check that the #013 O-ring on the outside of
the Manifold is in place and in good condition.

• Try turning off the ABS feature by turning DIP
#1 to the off position.

VELOCITY IS NOT CONSISTENT

• Make sure the paintballs you are using fit the
barrel good and are consistent in size.
The stock barrel with the RAIL™ is .690 size.
You should be able to blow the paintball
through the barrel but they should not roll
through the barrel on their own.

• Remove the bolt kit and re-lube it. Change any
O-rings causing a lot of friction. Make sure
#014 O-ring in bolt tip is in place and in
good condition.

• Raise the dwell.

• Change the battery.

• Check that the Hyper3™ regulator is working
good and that the pressure is consistent.
A separate regulator testing tool is available
for this. If needed, disassemble and change
worn out O-rings in the Hyper3™ regulator.

OTHER CATEGORIES

DOUBLE FEEDING

• If you get two balls firing at once change
the ball detents by removing the eye plates,
taking out the old ball detents and inserting
new ones.

BREAKING PAINT

• Make sure you use high quality paintballs and
that they are stored according to the
manufacturers instructions.

• Check that #14 O-ring on bolt tip is in place
and in good condition.

• Make sure your loader is working good and
that the rate of fire is not set higher than the
maximum feed rate of the loader.

• Check that the barrel you are using is not too
tight for the paintballs you are using.

• Check the condition of the ball detents.
