THE SAFETY SYSTEM The NINJA Regulator is equipped with an ASTM COMPLIANT bottle Burst Disk required by the Department of Transportation (D.O.T).
January 2023
In addition to the required safety burst disk, the regulator has a Low Pressure (LP) safety burst disk (stamped 1.8K). The LP (1.8K) safety burst disk is there to protect you and your marker in the unlikely event your Ninja regulator fails.
WARNING: Remember, most regulator failures are the result
of contaminated air.
If the LP (1.8K) safety burst disk vents, it did so for a reason. We recommend you do the following: Disassemble the regulator ( refer to Service and Rebuild procedures), inspect the regulator for contamination and clean if necessary.

Install a new LP (1.8K) Burst disk, PER THE INSTRUCTIONS ON PAGE 6, Available at most paintball shops and refill the system. If the LP (1.8K) burst disk vents after rebuild see and airsmith for help or call us at: 1(815) 477-0007. NINJA REGULATORS have a Safety Vent Groove on the stem ( as shown in below image). This lifesaving feature allows for the venting of the bottle, in the event the regulator is unscrewed from the bottle with pressure present in the bottle.
WARNING: ALWAYS CHECK TO MAKE SURE THERE IS NO GAP BETWEEN THE BOTTLE AND REGULATOR SEAL. SEE ILLUSTRATION BELOW.
WARNING: IF THERE IS A GAP STOP!! DO NOT FILL OR USE
YOUR SYSTEM.
Due to the high flow characteristics of the Ninja OFV Pin Regulator you may experience connection/activation difficulties with certain markers. To eliminate simply reduce the regulator’s output pressure to 500PSI by removing (2) Red Shims (#12) see page 4, Pressure Conversion.
WARNING: This is not a toy. Misuse may cause serious injury
or death. Eye protection designed specifically for paintball must be worn by the user and persons within range. Recommend 18 years or older to purchase. Persons under 18 must have adult supervision. READ OWNERS MANUAL BEFORE USING.
Safely drain your system and wait for the system to fully degas. Contact a qualified Air smith immediatley or call us at: 1(815) 477-0007. ASTM .825-14 NGO THREAD LOW PRESSURE BURST DISK

FILLING THE NINJA REGULATOR SYSTEM
PRESSURE ADJUSTMENT Unless ordered otherwise, all Ninja Regulators are shipped at a Standard 750-800 PSI output pressure + - (100) PSI the (SHP at 1100 PSI), If you wish to adjust the output pressure please follow these steps. Video guides available using the QR code provided or the URL address on the front page of this manual.
The NINJA Regulator system is equipped with the industry standard “QD Style” fill fitting, which allows your regulator system to be refilled either on or off the marker/gun. The regulator system may be filled with clean dry compressed air or nitrogen.
WARNING: Under no circumstances should the regulator
system be filled with pure oxygen. Oxygen will ignite causing injury or death. When filling your regulator system do not exceed the pressure.
WARNING: Do not apply or inject oil of any type into the fill
or burst disk ports. Oil will vaporize and possibly ignite during the fill procedure causing injury or death. It is important to keep dirt, oil, and water out of your Regulator system. Most regulator failures are due to dirt or contamination. Always keep a cover on the fill nipple when you are not filling the Ninja regulator system. If you use compressed air, make sure that the compressor providing that air is equipped with working filters and moisture separators. CONNECTING YOUR NINJA REGULATOR Slowly screw your Ninja regulator system into your marker/gun ASA fitting. It is recommended that you apply lube on the Ninja regulator bonnet threads. This simple procedure will reduce bonnet and ASA thread wear. The Ninja regulator has a pin valve which shuts off the gas delivery when the system is removed from the marker/gun. With any output above 1100PSI install the system on the marker/gun empty and only fill once connected.
WARNING: Due to the high output of the new pin seal regula-
tor you may experience connection/activation difficulties with certain marker/gun ASA. With any output above 1100PSI install the system empty and only fill once connected.

WARNING: Always wear eye protection, gloves and point the air system in a safe direction away from yourself and all bystanders prior to degasing or adjusting the system!
NOTE: The following tools may be required and are available at most hardware stores: - 3/32” Hex key wrench to remove bonnet set screws. - 10-32” Threaded machine screws 2” to 4” long to help remove bonnet.
WARNING: Before proceeding make sure your system has been completely degassed via the output pin valve to ensure no trapped gas is present! REFER TO THE NINJA REGULATOR PART DIAGRAM
1. Remove the two 10-32 #3 set screws that lock the Bonnet#2 ( the top portion of the regulator) to the regulator body #16. 2. Unscrew the Bonnet #2 counter clockwise from the Reg body. Bonnet should remove easily. If not, Make sure there is no air trapped in the Bonnet by depressing the pin valve. Helpful Hint: Insert the 10-32 x 2” to 4” screw into one of the bonnet set screw holes to ease the removal and reinstallation of the bonnet. Insert the screw into one of the bonnet screw holes until it stops or bottoms out, unscrew 1/8 to 1/4 turn. This will prevent the screw from damaging the gas body bonnet threads. Use the inserted screw to remove the Bonnet. Be careful not to strip the Bonnet hole or damage the body threads. 3. PRESSURE ADJUSTMENT FOR THE STANDARD NINJA REGULATOR.
