THE SAFETY SYSTEM
The NINJA FLEX Regulator is equipped with an ASTM COMPLIANT bottle Burst Disk required by the Department of Transportation (D.O.T) In addition to the required safety burst disk, the regulator has a Low Pressure (LP) safety burst disk. The LP safety burst disk is there to protect you and your marker/gun in the unlikely event your Ninja FLEX regulator fails. REMEMBER, Most regulator failures are the result of contaminated air. If the LP 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 Burst disk, PER THE INSTRUCTIONS ON PAGE 6, Available at most paintball shops

VIDEO GUIDES
If the LP burst disk vents after rebuild see and airsmith for help or call : 1.877.NINJAUSA (1.877.646.5287) 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. ALWAYS CHECK TO MAKE SURE THERE IS NO GAP BETWEEN THE BOTTLE AND REGULATOR SEAL. SEE ILLUSTRATION BELOW. IF THERE IS A GAP STOP!! DO NOT FILL OR USE YOUR SYSTEM

FILLING THE NINJA FLEX REGULATOR SYSTEM The FLEX Regulator system is equipped with the industry standard FLEX Regulator system to FLEX Regulator sysdry Compressed Air or Nitrogen. UNDER NO CIRCUMSTANCES SHOULD THE FLEX REGULATOR SYSTEM BE FILLED WITH PURE OXYGEN. OXYGEN WILL IGNITE CAUSING INJURY OR DEATH. FLEX Regulator system do not exceed the pressure rating shown on the CYLINDER’S LABEL. 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 FLEX Regulator system. Most that the compressor providing that air is equipped with WORKING separators.
CONNECTING YOUR FLEX REGULATOR SLOWLY Screw your FLEX that you apply lube on the FLEX Regulator bonnet threads. This simple procedure will reduce bonnet and ASA thread wear. The FLEX system is removed from the marker/gun. With any output above 1100psi install the system on the
DUE TO THE HIGH OUTPUT OF THE NEW FLEX PIN SEAL REGULATOR 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.
PRESSURE ADJUSTMENT
Unless ordered otherwise, all Ninja FLEX Regulators are shipped at their lowest pressure output
ALWAYS WEAR EYE PROTECTION, GLOVES AND POINT THE AIR SYSTEM IN A SAFE DIRECTION AWAY FROM YOURSELF AND ALL BYSTANDERS PRIOR TO DEGASSING OR ADJUSTING THE SYSTEM! NOTE: THE FOLLOWING TOOL MAY BE REQUIRED AND WAS SHIPPED WITH YOUR FLEX REGULATOR: 30-32 Hook spanner wrench. When adjusting you must activate or vent the regulator with every 1/6 of a turn or every notch on the adjusting collar.
DO NOT EXCEED AN OUTPUT PRESSURE OF MORE THAN 3000PSI You should you always start at the lowest setting and adjust up to the desired output. Please note the adjustment marks on the adjustment collar indicating which way will increase or decrease the output pressure. Turning the collar up toward the bonnet will lower/decrease the output pressure and turning the collar down toward the body will raise/increase the output pressure. NOTE: TO REDUCE WEAR ON THE ADJUSTMENT COLLAR WE RECOMMEND YOU PERIODICALLY APPLY A DROP OR TWO OF AIR TOOL OIL TO THE ADJUSTMENT COLLAR THREADS ON THE GAS DISTRIBUTION BODY (#17) AND TO EACH ADJUSTMENT BALL (#14)
NEVER INJECT OIL INTO THE FILL PORT VALVE(#16). OIL DROPLETS CAN VAPORIZE AND IGNITE DURING THE FILL PROCEDURE CAUSING INJURY OR DEATH THE OUTPUT GAUGE (MARKED “OUTPUT” ON THE GAS DISTRIBUTION BODY) WILL NOT SHOW ANY ADJUSTMENT TO PRESSURE WHEN DECREASING UNTIL THE SYSTEM IS VENTED OR ACTIVATED. © 2010-2023 Pressure Specialist Inc.
