MAINTENANCE
The eXTCyTM has been designed with
simplicity in mind so that you can
concentrate on your game instead of your
marker. It has only one major moving part in
its valve system, with a minimal number of
seals. This DOES NOT mean that you should
neglect your eXTCyTM. If you take care of
it off the eld, your eXTCyTM will take care
of you on the eld. For best performance,
clean and grease your eXTCyTM frequently.
Many players disassemble and clean their
eXTCyTM after every day of use. While this
may seem a bit extreme, being vigilant in the
upkeep of your eXTCyTM will extend its useful
life considerably, and catch any problems
when there is time to correct them before
the next game. Playing in the rain will not
damage your eXTCyTM. In fact, the eXTCyTM.
has been tested and proven to function
underwater. However, long-term exposure
to moisture can cause rust damage to
some of the eXTCyTM’s screws, so if your
eXTCyTM should become waterlogged,
remove the barrel, stock, eye covers and
rubber grips and allow it to dry out, then
follow the disassembly instructions for full
cleaning. Clean out mud and paint with
a damp cloth and alcohol. Lubricate the
eXTCyTM ONLY with GR33SETM pneumatic
grease. Use fresh, high quality paintballs for
best performance.

BARREL BLOCKER/HOPPER
PLEASE READ CAREFULLY
BARREL BLOCKER
The Barrel Blocking Device is a critical piece of paintball safety equipment - nearly as important as
paintball goggles. The Barrel Blocker serves to protect against accidental discharge of a paintball by
catching it before it can cause harm. A Barrel Blocker is included with the eXTCyTM and must be used
every time it is handled in an area where people or property are not properly protected by paintball
goggles or paintball eld netting. To use the Barrel Blocker simply slip it over the end of the barrel
and stretch its cord back over the back of the eXTCyTM or the rearmost part over which it can be
securely looped. Use the strap’s adjuster to cinch the strap tight, so that the Barrel Blocker can provide
protection against accidental discharge of a paintball.
The Barrel Blocker should only be removed when the eXTCyTM is on a “live” paintball eld and all
persons involved are wearing proper paintball protection.
HOPPER
The eXTCyTM is a high performance tournament grade paintball marker. Its low-force bolt and VisionTM
anti-chop system will prevent paintballs from being chopped if the hopper is not able to load paintballs
as fast as the eXTCyTM is being red. If you want to realize the eXTCyTM’s maximum repower potential,
you will need to use a high performance loader. High performance loaders, especially those which
provide force-feeding, will yield the best results with the eXTCyTM.
The eXTCyTM is equipped with a clamping feedneck that allows it to adapt to the small size differences
in hopper neck sizes, yet lock or release quickly. Using a 7/64-inch allen wrench, loosen the clamping
feedneck before installing a hopper.

GASES
NEVER PUT OIL IN A COMPRESSED AIR REGULATOR OR
TANK - ONLY APPLY MANUFACTURER RECOMMENDED
LUBRICANTS.
COMPRESSED AIR
TM
The eXTCy
is a low-pressure paintgun. It operates at approximately 160 psi, which means it is capable of
functioning well with either high-pressure compressed air or CO2 as a power source. Proper set up of your
gas system will help you obtain the best possible performance from your eXTCyTM.
Whether using compressed air or CO2 it is important that the eXTCyTM is not exposed to sudden “pops”
of pressure. Always turn-on or screw-in a compressed air system or CO2 slowly, so that the valve opens
slowly and the gas pressure inside the marker is raised smoothly. Be gentle to the internals of your
eXTCyTM and they will reward you with a long service life.
High Pressure Air systems (HPA) are the preferred power source used in paintball and with the eXTCy
TM
because they are unaffected by temperature uctuations and do not have the potential for liquid
problems. HPA systems consist of a tank and a regulator, and are typically rated to store air or nitrogen
at pressures of 3,000 or 4,500 psi. Although pure nitrogen is almost never used in paintball, many players
call compressed air “nitro” as air is made up of more than 70% nitrogen, allowing the two gasses to be
used interchangeably in paintball equipment.
The eXTCy
TM
is congured for use with screw-in style HPA systems. Although HPA systems pre-set to
deliver approximatly 400 psi (low output) will work with the eXTCyTM, 800 psi (high output) systems are
preferred, to reduce the risk of gas starvation under rapid re.
Never use oil or any petroleum based cleaner or lubricant in a compressed air regulator or tank. Exposure to
pressurized air increases oil’s ammability and can cause a serious safety hazard. Only use manufacturer
recommended lubricants with compressed air systems, and follow the manufacturer’s maintenance and
operation instructions explicitly.
If you are using your eXTCyTM with an adjustable output compressed air system, it should be set to deliver
about 800 psi. The eXTCyTM’s vertical regulator can accommodate a wide range of input pressures, so
exact adjustment of the air system is not critical.
NOTICE
Due to shipping restrictions, CO2 and HPA tanks are sold empty. They must be lled before they can be
used. Most paintball shops and elds are equipped to ll HPA tanks. Paintball shops, elds, many hardware
stores and sporting goods stores will have the equipment and trained personnel to ll paintball CO2 tanks.
FIG. 3
HPA TANK BEING FILLED
NOTICE
TM
The eXTCy
is factory congured for use with
CO2. Its dwell setting must be changed to obtain
optimum performance with HPA. See the Firing
Modes / Dwell section of this manual to learn how.
NOTICE
Although the eXTCyTM can be powered by
compressed air, typical home, garage or industrial
air compressors cannot provide the high pressures
required to ll a paintball HPA tank. Paintball HPA
systems can be relled by paintball elds and
stores which use higher pressure compressors
similar to those used in the SCUBA and reghting
industries.

PLEASE READ CAREFULLY
USING CO
CO2 is usually not recommended for electronic paintball markers. This is not the case, however with
the eXTCyTM. The eXTCyTM can function extremely well with CO2 as a power source, but doing so does
require the correct conguration. The use of CO2 will not damage the seals in the eXTCyTM, freeze or
cause damage to its circuit board.
The important thing to remember if using CO2 is that best performance can be achieved when only
gasseous CO2 is fed to the eXTCyTM, and liquid CO2 remains in the tank.
Although the relief valve integrated into the eXTCyTM’s vertical regulator provides the marker with
protection from pressure spikes, those pressure uctuations can cause poor performance, and
temporary blockage of the eXTCyTM’s solenoid valve.
The bottom-line ASA tting on the eXTCyTM places the CO2 level, like in Figure 5. When the marker is
held in typical ring positions the liquid CO2 will pass through the valve into the marker unless an anti-
siphon system is used.
Anti-siphon CO2 tanks contain a J-shaped tube that draws gaseous CO2 from the top of the tank
when it is in a horizontal position. Anti-siphon tubes must be professionally installed, to ensure that
critical safety checks are performed during valve installation. Anti-siphon CO2 tanks should not be
used with remote hoses.
Alternative CO2 arrangements include placing the CO2 tank vertically in a pack, and using a paintball
remote hose to feed CO2 to the eXTCyTM. This arrangement not only prevents liquid CO2 from entering
the marker, but also makes the marker assembly lighter weight. Another possible conguration is to
use a third-party ASA or ASA mounting adapter which mounts a standard CO2 tank at an angle like in
Figure 4. In this arrangement gravity keeps the liquid CO2 below the valve neck.

The bottom-line ASA tting on the eXTCyTM can be removed by unscrewing the two industry-standard
10-32 mount screws holding it to the grip frame after unscrewing and removing its on/off knob. If
replacing the ASA, be sure the model chosen takes into account the type of gas system being used
(horizontal for anti-siphon CO2 tanks or compressed air, angled for standard CO2 tanks).

WHEN STORING FOR FOR
BATTERY
TM
The eXTCy
consistently deliver the amperage needed to operate the eXTCy
is powered by a standard 9-volt alkaline battery. Lower cost “heavy duty” batteries will not
TM
reliably. Erratic performance, especially
drops in velocity or skipped shots during rapid re can result from a battery that is not delivering full
power.
The eXTCyTM is also compatible with 9-volt rechargeable batteries. Because specications of batteries
vary widely from brand to brand, use of any rechargeable battery will require testing to determine if it
can power the eXTCyTM reliably and t correctly in the grip frame. Some NiCD “9v” rechargable batteries
actually operate at 7.2 volts. These types of batteries will not work well with the eXTCyTM.
Each time the eXTCyTM is turned on, the power button LED will blink 5 times rapidly, with its color indicating
the estimated charge level of the battery. Green indicates a charge level between 75% and 100%. Yellow
denotes a charge level between 50% and 75%, while red ashing indicates that the remaining charge is
estimated to be below 50%. It is important to note that different types and even brands of rechargeable
batteries will give different readings than alkaline batteries., so experience will be the best teacher as to
how much remaining use to expect once a reduced charge level is indicated.
Any time the eXTCyTM exhibits erratic performance, drops velocity or skips shots while rapid ring, does
not shoot or does not turn on, the rst step in troubleshooting should always be to replace the battery with
a brand-new, name-brand alkaline battery.
To replace the eXTCyTM battery, use a 5/64-inch allen wrench to remove the two screws from the left side
of the rubber grip, then open the grip. Be careful opening the grip from the grip frame. Folding the grip
back around the trigger frame may seem convenient, but may cause tearing or stretching in the center of
the grip, which will cause it to pucker or t poorly when reinstalled. As an alternative to folding the grip
open, simply remove it entirely by removing the two grip screws from its right side.
FIG. 6
ALKALINE BATTERY
Remove the old battery, taking care not to bend, kink or strain its wires. Unsnap the battery from its
connector by pulling on the connector, not the wires. Snap in a fresh battery, then place that in the grip
frame, tucking the wires into place, before closing and re-securing the grip. The battery and connector
should t snugly in the battery space, so that they do not shift around during use. Some off-brand batteries
may be too large to t correctly in the grip frame. If this is the case, do not force the battery into position,
instead replace it with a name-brand alkaline battery.

VISION OPERATION
VISION BYPASS
The eXTCyTM is equipped with a VisionTM break-beam anti-chop system, allowing it to acheive the
highest possible rates of re without chopping or mis-feeding paintballs.
The eXTCyTM circuit board is linked to a light emitting diode and detector installed in the marker’s
breech. When a paintball drops down the feedneck into the breech, it breaks the light beam and
the eXTCyTM circuit board detects its presence. When the VisionTM system is activated, the eXTCyTM
will not re until it “sees” a paintball in the breech. This prevents the marker from dry ring or from
chopping a paintball in half by ring before the ball is completely loaded.
There may be times when it is desirable to bypass the VisionTM system, such as dry-ring the eXTCyTM
to test electronic adjustments, or when de-gassing.
While the eXTCyTM is turned on, pressing and holding the power button for approximately one-half
second will turn the VisionTM system off, allowing the marker to re whenever the trigger is pulled,
whether or not there is a paintball in the breech. Pressing for approximately a half second will also turn
VisionTM back on.
When VisionTM is on, the power button will glow green. When it is off, the button will glow red.
