PIRANHA® OPERATOR’S MANUAL
The Piranha® is a paintball marker designed to shoot .68 caliber paintballs for use in the sport of paintball.
Paintball is a recreational and competitive sport played worldwide. Special equipment used in paintball includes
paintball markers, which are airguns; and paintballs, which are liquid-filled gelatin capsules that mark with a
bright color. The object of the game is to capture the opposing team’s flag; while on that quest, players try to
mark their opponents to eliminate them from the game.

READ THIS OPERATOR’S MANUAL COMPLETELY BEFORE LOADING, PRESSURIZING, OR OPERATING THE
PIRANHA® PAINTBALL MARKER.
Always wear protective goggles and headgear specifically designed for paintball when shooting this or
any paintball marker.
Every person within range of an area where a paintball marker is in use must wear protective goggles
and headgear specifically designed for paintball.
Operate a paintball marker only in areas where it is safe and lawful to do so.
Misuse of this paintball marker can result in criminal penalties, including jail time.
This marker is intended for sale to adults 18 years of age or older only. Adult supervision is recommended at
all times whenever a minor is handling this marker in any manner.
During game play, follow referee’s instructions and all field safety rules. Avoid shooting at a player’s
head, neck, or groin area.
Play paintball only where the rules of safe paintball play are followed.
All paintball markers must be chronographed regularly. Adjust marker to shoot paintballs at a velocity less than
300 feet per second (fps) and/or that does not exceed the velocity limit set by the paintball park where the
marker is in use. Chronograph the marker at regular intervals during the day, as well as any time the air source
is refilled or changed, any time the barrel is changed, and upon request of any player or game official.
There is always a chance that a paintball is lodged in the barrel of the marker even when it is not visible in the
chamber. To check if the marker is unloaded: remove air system and shoot marker in a safe
direction. Remove hopper, visually inspect chamber for a paintball, remove and inspect barrel for the presence
of a paintball. Never look down the barrel of any paintball marker once the barrel is screwed into the marker.
Markers with regulators hold pressure even after tank is removed. Shoot marker in a safe direction after tank is
removed to de-gas it completely.

PAINTBALL BASIC SAFETY RULES
This paintball marker operates using compressed gas or air at specified pressure ranges. Follow safety
procedures when handling compressed gas or air. All filling of compressed gas or air cylinders must be
done by qualified persons.
Always cock marker before attaching air or gas source to it. Failure to always cock marker before attaching
air to it may cause accidental firing or discharge of paintballs.
Follow the rules of safe marker handling: Keep finger off trigger until ready to shoot. Keep muzzle
pointed in a safe direction. In addition, firmly insert a barrel plug or barrel bag into the muzzle and push
the electronic or mechanical safety “on” when the marker is not in use and when in any non-shooting area.

operating the piranha® marker
WA R N I N G
Every person within range of an area where a paintball marker is in use must wear protective goggles and
headgear specifically designed for paintball.

1. Attach threaded barrel firmly to marker.
2. At this time, do not attach air source or loader and do not
load paintballs into marker.
3. Insert barrel plug firmly into barrel.

Paintball markers with electronic frames have extremely sensitive triggers. Take extra safety precautions anytime
handling or shooting an electronic paintball marker. To avoid accidentally firing the marker, keep the marker
off until you are ready to fire.
Never shoot at domestic animals or wildlife.

4. Pull the cocking knob straight back from the rear of the marker until
the cocking mechanism locks back in the cocked position. See Figures
1. Always cock marker before airing it up. During cocking the flush cocking rod will recoil or “spring back” into the marker once released and
will only move slightly during marker operation. See Figures 2 and 2a.

Never mark objects outside the confines of the game or authorized shooting areas.

Figure 1. Pull Back

Figure 2. Pull Back

5. Push safety “off”
Never look down the barrel of the marker.
Never aim or shoot a paintball marker (loaded or unloaded) toward any person who is not wearing protective
goggles and headgear specifically designed for paintball.

6. Squeeze the trigger with an even pressure. The cocking knob will snap
forward into the uncocked position.
7. Cock the marker.

Before disassembly, storage, or transport of the marker, remove all paintballs from the marker, barrel, and

Figure 2a. Fully Cocked

loader; remove air source; and remove all gas or air from the marker. Insert barrel plug and put mechanical
safety in “no shoot” position.
Carry marker in case or sturdy bag when in public.

WA R N I N G
Always cock marker before attaching air source. Marker can discharge if air source is attached before
marker is cocked.

Safely and securely store marker to prevent access to it by unauthorized persons.

Safety standards information is available from the American Society for Testing and Materials, 100 Barr
Harbor Drive, West Conshohocken, PA 19428-2959; phone 1.610.832.9500; www.astm.org. “Standard Practice
for Paintball Field Operation” is publication F1777-97, and “Standard Specification for Eye Protective Devices
for Paintball Sports” is publication F1776-97; inquire about additional publications which may be available
at the time your request is made.

8. Follow safety rules for handling compressed gas/air. If any leak occurs in the marker, refer to
troubleshooting guide or to a qualified airsmith. Use only cylinders for compressed gas or air that comply with
all applicable laws and regulations, including but not limited to those of the U.S. Department of Transportation,
OSHA, Compressed Gas Association, and/or American Society for Testing and Materials.
Bottomline: First check the tank O-ring for rips or tears, then attach the air source by screwing the
threads of the tank or air source adapter into the threaded bottom line ASA at the base of the grip. Make
sure marker is cocked before attaching air. If leaks occur, recheck tank O-ring. If damaged, replace.

WA R N I N G
WHEN COCKING THE PRESSURIZED MARKER, DO NOT RELEASE THE COCKING KNOB UNTIL AFTER THE
COCKING MECHANISM HAS LOCKED BACK INTO THE COCKED POSITION; RELEASING THE COCKING KNOB
DURING COCKING CAN CAUSE THE MARKER TO SHOOT.
9. With goggles on, test for function after attaching air source: Squeeze the trigger. The marker should shoot
air and the cocking knob should cycle forward and back, stopping in the cocked position, after each trigger
squeeze, Repeat several times. Flush cocking rods will bobble some, but they will not come out all the way.
The Piranha® marker shoots one paintball for each squeeze of the trigger, and recocks itself after each shot.
10.Turn the marker off (electronic version) or slide safety forward (semi-auto version). Paintballs may then be loaded.

WA R N I N G
Before disassembly, storage, or transport of the marker, remove air source first, then remove all paintballs
from the marker, barrel, and loader. Remove all gas or air from the marker. Insert barrel plug and slide
the mechanical safety forward so the safety is engaged and red dot isn’t showing.

COMPRESSED GAS/AIR
Do not leave cylinder or pressurized marker in direct sunlight or exposed to heat source. Increased
temperature will increase the pressure of compressed gas or air to dangerous levels. Piranha usually
needs 650 p.s.i. to cycle and attain correct velocity.

VELOCITY ADJUSTMENT
WA R N I N G
All paintball markers must be chronographed regularly. Adjust marker to shoot paintballs at a velocity
that is less than 300 feet-per-second (fps) and/or that does not exceed the velocity limit set by the
paintball park where the marker is in use.
Chronograph the marker at regular intervals during the day, as well as any time the air source is refilled
or changed, any time the barrel or any part in the marker is changed, and upon request of
any player or game official.
1. Chronograph the marker using standard chronograph procedures and following safety rules. Shooting
velocity will vary based upon many factors, such as paint, weather, and air system.
2. Adjust velocity by using a 3/16" allen wrench to turn the velocity adjuster. See Figure 6. Turn adjuster
clockwise to raise velocity. Turn adjuster counter-clockwise to lower velocity. See Figure 7. Turning the
velocity adjuster changes the amount of tension on the hammer spring. The hammer spring may be
changed for additional velocity adjustment; insert stiffer spring to raise velocity and less stiff spring
to lower velocity (spring tension in order of strongest to weakest: red, blue, white). See next page for
more about springs.
3. Chronograph the marker after every velocity adjustment.
4. Chronograph the marker at regular intervals during the day, as well as any time the air source is
refilled or changed, any time the barrel or any part in the marker is changed, and upon request of
any player or game official.

The safety is a small mechanical slide on the left side of the marker above the trigger.
When the safety is “off,” a red dot is visible on the marker. The trigger can still be
pulled if the safety is “on,” but the marker will not fire or de-cock.

The Piranha® paintball marker may be powered by CO2, regulated compressed air, or regulated nitrogen.
THE SAFETY RULES FOR HANDLING COMPRESSED GAS OR AIR MUST BE FOLLOWED AT ALL TIMES.

OPERATING PRESSURE AND INPUT PRESSURE
• Operating pressure range: 500 to 1000 p.s.i. on Piranhas without regulators.
• Recommended maximum input pressure is 1000 p.s.i.
• Do not exceed recommended pressures.

VELOCITY ADJUSTMENT SPRINGS
The hammer spring assembled with the Piranha® paintball marker is intended to provide appropriate
shooting velocity for most outdoor paintball game situations and will provide a range of velocities
suitable for most conditions. Shooting velocity will vary based upon form of regulated compressed gas
or air used to power the marker, outside temperature, and other factors.
DO NOT EXCEED A VELOCITY OF 300 FEET-PER-SECOND (fps).

LUBRICATION
It is recommended that 100% synthetic paintball marker oil be used for lubricating the marker. Do not use any
oil aside from paintball marker oil or you run the risk of ruining the O-rings.
1. Before each insertion of the removable air source (tank or remote line) into the ASA, clean the threads and
put two drops of oil onto them.
2. After removing the bolt/hammer assembly, clean off any paint or dirt. Put 1 drop of oil onto each O-ring. See
Figure 11. Only replace the Blue Hammer O-ring (#35) with another Blue Hammer O-ring, or the marker will
not re-cock properly.
3. Before screwing the barrel onto the marker, clean the barrel threads.

maintenance and reassembly
button is located on the left side of the marker near the top of the left grip panel. Continue to press assembly
into marker. Pushing the button allows the bolt/hammer assembly to slide easily the rest of the way into the
marker. The sear release slide has to be pushed up on eForce frames. See
Figure 36.
3. Field strip pin must be inserted into the left side of the marker.
4. After reassembly, follow the procedures in this manual for adding air system, loader, and paintballs.
Figure 12

4. The fastest way to oil the entire Piranha® is to take off the barrel; put 6 drops of oil into the ASA (#43),
screw the bottle in over the oil, and shoot the marker a dozen times without the barrel.
5. There is no need to ever oil the inside of the barrel. Oil in the barrel will decrease accuracy.

REGULAR MAINTENANCE FOR THE PIRANHA®
1. Clean out all broken paint regularly. Do this before you oil the marker.
2. Oil marker each time you play with synthetic marker oil. Never use 3-in-1. Non-synthetic oil can contaminate
the ball detent and hammer O-ring, causing the marker not to function.

3. The fastest way to oil your Piranha is to drop 6 drops in the ASA (#43) and screw the bottle in over it.
Take the barrel off and shoot the marker a dozen times to cycle oil throughout the marker.
4. Inspect the bolt O-rings and Blue Hammer O-ring after each time you oil the marker. Make sure they are
getting oil.
5. Clean out the vertical feed, as well as the barrel. If any oil or paint is present, the marker will not shoot accurately.
6. Never wash the bolt assembly with water unless you are going to oil them before you reassemble them.
Dry before oiling.
7. Check ball detent (#20) every 25,000 shots. Replace if it is worn or broken.
8. Never stretch hammer spring to increase velocity. This will shorten the life span of the spring.

REASSEMBLY PROCEDURE (sear release slide)
1. See Figures 15 through 26, which shows the procedure for reassembly of the bolt/hammer assembly. Once it is
reassembled, hold the bolt/hammer assembly in one hand. See Figure 24. Push it gently into the marker until it
stops sliding forward, which will be about halfway into the body of the marker. See Figure 25.
2. Before it stops sliding forward, push the Sear Release Slide button forward. See Figure 25. The Sear Release Slide

Safety Slide

OPERATING THE PIRANHA® GTI PLUS: 1. Attach threaded

barrel firmly to marker. 2. At this time, do not attach air source or loader
and do not load paintballs into marker. 3. Insert barrel plug firmly into barrel. 4. Pull the cocking knob straight back from the rear of the marker until
the cocking mechanism locks back in the cocked position. Always cock marker before airing it up. During cocking the flush cocking rod will recoil or
“spring back” into the marker once released and will only move slightly during marker operation. 5. Slide safety “off,” 6. Squeeze the trigger with an
even pressure. You should hear the hammer and bolt assembly slide forward.
7. Cock the marker. 8. Before attaching the air source, read and understand
the section in the manual on “Compressed Gas/Air.” Follow safety rules for
handling compressed gas/air. If any leak occurs in the marker, refer to troubleshooting guide or to a qualified airsmith. Use only cylinders for compressed gas or air that comply with all applicable laws and regulations,
including but not limited to those of the U.S. Department of Transportation,
OSHA, Compressed Gas Association, and/or American Society for Testing and
Materials. 9. With goggles on, test for function after attaching air source:
Squeeze the trigger. The marker should shoot air and the cocking knob
should cycle slightly after each trigger squeeze, repeat several times. Flush
cocking rods will bobble some, but they will not come out all the way.
10. Slide safety forward (semi version). Paintballs may then be loaded.
