Install the supplied elbow
onto the SP-8’s feedneck
and mount your loader in
the elbow. Due to the high
rates of fi re that the SP-8
can achieve, we recommend the use of a modern
high-performance loader
(see the Hopper section.)
Put the supplied barrel
blocker over the end of
the barrel, securing its
cord as far back on the
SP-8 body as possible,
and cinching it tight.
Gently gas up the marker
by slowly turning on the air
system or ASA’s on/off valve,
or slowly screwing the CO
compressed air system into
the ASA.
A gentle rise in pressure is
important, as a sudden blast
may reduce the service life of
the SP-8’s internals.

or CO
who is properly trained to do so.
If using an HPA system with an
on/off valve, such as the Max-Flo
or Max-Flo Micro, make sure it is
in the OFF position.
Turn on the marker by holding the power button down for
approximately 2 seconds. The
marker will turn on with Vision
mode activated. The light will blink
slowly if there is no paintball in
the breech, or rapidly if there is.
To de-activate Vision mode, press
the power button briefl y and it will
blink in a double-tap sequence.
Press it briefl y again to re-activate
Vision mode. Press and hold the
power button for approximately 2
seconds to turn the SP-8 off.

Fill the loader with paint and turn it on. While wearing ASTM compliant paintball goggles, in an area where all bystanders are protected, remove the barrel blocker and fi re over
a chronograph to measure the velocity. Expose the SP-8’s vertical reglator by removing the magazine. Using a 5/8-inch open-end wrench or adjustable wrench on the fl ats at
the bottom of the vertical regulator, turn clockwise to increase velocity/pressure, and counter-clockwise to decrease. Take three or four shots after every adjustment to allow the
gas pressure inside the SP-8 to stabilize. Adjust until the marker is fi ring consistently within the limits for the fi eld where you are playing (for safety reasons, never adjust the SP-8
to fi re at greater than 300 feet per second.) As you adjust, check the marker’s pressure gauge to be certain you stay below the SP-8’s operating limit of 200 psi. Depending on
what modes of fi re are allowed at the fi eld where you are playing (semi-automatic, rebound, etc.) you may need to adjust the SP-8’s fi ring mode. See the Electronic Adjustment
section for more information. Shoot out the competition, hang the fl ag and win the game.

MAINTENANCE
The SP-8 has been designed to handle the rigors of scenario style paintball while providing tournament
level performance. It has a minimal number of moving parts and seals so that you can maintain the marker
with little effort. This DOES NOT mean that you should neglect your marker. If you take care of it off the
fi eld, your SP-8 will take care of you on the fi eld. For best performance, clean and grease your SP-8 frequently. Many players clean their marker after every use. While this may seem a bit extreme, being vigilant
in the upkeep of your marker will extend its useful life considerably. Playing in the rain will not damage
your SP-8, but you should NEVER immerse it in water. If your marker should become waterlogged, remove
the barrel, body cover and rubber grips and allow them to dry out, then follow the disassembly instructions for full cleaning. Clean out mud and paint with a damp cloth and alcohol. Grease the SP-8 ONLY
with SL33K pneumatic grease. For best performance, use high quality paintballs.

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 SP-8, and must be used
every time the marker is handled in an area where people or property are not properly protected by
paintball goggles or paintball fi 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 marker 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 marker is on a “live” paintball fi eld and all persons involved are wearing proper paintball protection.
HOPPER
The SP-8 is a high performance scenario paintball marker capable of high rates of fi re. The breakbeam Vision system means that you won’t need to worry about chopping paint because your trigger
fi nger is faster than your hopper. However, if you want to realize the marker’s maximum fi 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 SP-8.
Included with the SP-8 is a 45-degree elbow for attaching standard paintball hoppers. Slide the
narrow end of the elbow onto the SP-8’s feedneck and secure it in place by tightening its wing-nut.
Place your hopper in the top of the elbow and secure it similarly.

GASES
Never put oil in a compressed air regulator or tank—only
apply manufacturer specifi ed lubricants.
The SP-8 is a low-pressure paintgun. It operates optimally at 180 psi, which means it can function well
with either compressed air or CO2 as a power source. Proper set up of your gas system will help you
obtain the best possible performance.
High Pressure Air systems (HPA) are the most common power source used with the SP-8, as they are
unaffected by temperature fl 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 (while pure nitrogen is
almost never used in paintball, many players call compressed air “nitro” as air is made of more than 70%
nitrogen) at pressures of 3,000 or 4,500 psi.
There are two main types of HPA systems, those on which the output pressure is adjustable, and those
for which their regulator is pre-set to a fi xed output pressure. HPA systems designed to screw into an
ASA are usually pre-set to deliver either 400 psi (low pressure output) or 800 psi (high pressure output.)
Never use oil or any petroleum based cleaner or lubricant in a compressed air regulator or tank. Exposure to pressurized air increases oil’s fl 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 SP-8 with an adjustable output compressed air system, it should be adjusted to
deliver about 650 psi to the marker’s vertical regulator. The SP-8’s regulator can accommodate a wide
range of input pressures, so exact adjustment of the air system is not critical, and either low output, or
high output pre-set HPA systems may be used as well.
While CO2 can also be used, it is less popular, since its pressure fl uctuates with temperature and use.
The important thing to remember when using CO2 is that liquid CO2 must not be delivered to the marker.
If liquid CO2 were to make it past the vertical regulator, it could expand into gas form inside the paintgun,
raising the pressure levels high enough to cause damage to internal seals, hoses or the solenoid valve.
Because liquid CO2 is heavier than CO2 gas, it is easily blocked through the use of gravity.

GASES
PLEASE READ CAREFULLY
Two easy ways to properly use CO2 with the SP-8 are an anti-siphon tank or a remote line.
Anti-siphon tanks have a J shaped tube professionally installed inside. When the tank is screwed into a
bottom line ASA, such as the one that is standard on the SP-8, the tube delivers gas only. The anti-si-
phon tube works like a diver’s snorkel, repositioning the gas intake from the valve to the top side of the
tank. When an anti-siphon tube is installed in a tank, the airsmith will usually mark the valve, to indicate
the position of the tube. When the tank is screwed into a marker, this mark must be oriented to the top.
A remote hose allows a standard (non-siphoned) CO2 tank to be carried in a player’s pack. Not only does
this reduce the total weight of the marker, but it also allows the tank to be placed vertically, so that its
valve is at the top while gravity holds the liquid CO2 at the bottom. It is important to note that lying down
on the fi eld or crawling while using a remote can cause liquid CO2 to be fed to the paintgun as the tank is
turned on its side. Remote hoses offer an additional advantage, like straight-rails and drop-forwards they
move the CO2 or HPA tank to allow use of the optional SP-8 Adjustable Stock.
Whether using compressed air or CO2 it is important that the marker is not exposed to sudden “pops”
of pressure. If using a standard ASA with a screw in HPA system or CO2 tank, screw the tank in slowly,
so that the valve opens slowly and the pressure rises gently. If using an ASA with a built in on/off valve,
screw in the tank fully, then open the valve slowly. If using an HPA system or CO2 tank with its own on/off
valve, open that valve slowly. Be gentle to the internals of your marker and they will reward you with
a long service life.
IMPORTANT
CO2 can also be used with remote hose
with-out Anti-Siphon. [Not Shown]

GAS SYSTEM MOUNTING
PLEASE READ CAREFULLY
The SP-8 uses paintball industry standard gas system mounting. At the bottom of the grip frame, it has
a pair of 10-32 screw holes.
The SP-8 is preconfi gured with a standard duckbill style ASA mounted on bottom of the grip frame. To
remove this ASA, degas and unload the marker. Use a #1 Phillips Screwdriver to remove the four grip
screws and the rubber grip. Use a 1/8” allen wrench to remove the two ASA mount screws.
The ASA can be replaced with a mounting rail or drop forward to place the gas source in a position that
is most comfortable for you. The stock SP-8 rubber grip is not compatible with all ASAs, or most dropforwards, without modifi cation.
If the rubber grip will not fi t correctly with your new custom set-up, carefully cut off the lower cup portion with a set of heavy-duty kitchen shears, following the existing cut-lines. Carefully lubricating the
utility scisors with SL33K minimize binding for a smoother cut.

PAINT / VELOCITY
PLEASE READ CAREFULLY
PAINT
Even the best quality paintballs will vary in size from one batch to the next and as weather conditions
change. While your marker will work well even with a poor paint to barrel fi t, optimal performance will be
achieved with a proper fi t. Paintgun barrels are available in a variety of bore sizes to allow the user to select
the best possible fi t, and barrel kits like The Freak allow for easy adjustment to paint of different diameters.
The ideal fi t between the paintball and the barrel is when the ball is inserted in the bore (the end that
screws into the marker) and does not slip or roll through to the muzzle (the business end) on its own. The
ball should sit in place, even when the barrel is pointed straight down. If the paintball can roll out on its
own, the fi t is too loose. The ball should be able to be expelled from the barrel by blowing it out like a
blowgun, using a minimal amount of breath. If the ball is diffi cult to blow through, the fi t is too tight, which
can lead to ball breakage.
VELOCITY
The velocity, or speed at which a marker fi res a paintball, must be measured and adjusted to below the
paintball fi eld’s velocity limit immediately before each day of play. This is required for player safety. If CO2
is used, velocity should be checked and adjusted multiple times during the day. To access the verticcal
regulator for velocity adjustment, press down on the magazine release lever and pull the magazine down.
While wearing proper paintball specifi c goggles and protective equipment, and in an area in which all
persons and property are properly protected, fi re three or four shots over a chronograph and if necessary
change the velocity by adjusting the vertical regulator with a 5/8-inch open-end or adjustable wrench.
Turn clockwise to increase velocity/pressure, and counter-clockwise to decrease. Take three or four shots
after every adjustment to allow the gas pressure inside the marker to stabilize. Adjust until the marker is
fi ring consistently within the limits for the fi eld where you are playing. For safety reasons, never adjust the
marker to fi re at greater than 300 feet per second. As you adjust, check the pressure gauge to be certain
you stay within the SP-8’s operating pressure range of 160 to 200 psi. Optimal pressure is 180 psi.
Replace the magazine after velocity adjustment has been completed.
