The Ninja LPRV2 is designed to be used with a standard regulated paintball air source.

Paintball air source is available in 3000 and 4500 psi boles. The paintball tank must have a

regulator, which regulates the air source the Max regulator output is 500 psi. Ninja oers a full line of air systems, visit www.ninj

Quick start guide:

 Verify Adjuster (Figure 1: A.) is at the maximum, turning counter clockwise until it stops, using a

3/16 Allen (hex) key.

 Completely attach the regulated air source with a verified output pressure of 500 psi.  The pressure gauge is for reference only. The velocity should be set following the engine

manufacturers specifications utilizing a chronograph designed for airsoft use.

 Rotating the adjuster CLOCKWISE will INCREASE the output pressure.  Rotating the adjuster COUNTER CLOCKWISE will DECREASE the output pressure.  In General, increasing the output pressure will increase the velocity of the airsoft engine.

o Using small 5° Clockwise adjustments (right hand) to increase velocity and verify using a

chronograph.

o Small Counter Clockwise adjustments to reduce velocity must be followed by several

clearing shots.

o If the air pressure is increased beyond the factory Resetting Pressure Relief Valve

(Figure 1: D.) set point (140-150psi), the Resetting Pressure Relief Valve will begin to vent. Quickly turn the adjuster at least one full turn Counter Clockwise to decrease the pressure output and the Resetting Pressure Relief Valve will reset.

 Due to the Ninja LPRV2 design, the air source tank and regulator should turn easily, unthread

from the Ninja LPR smoothly and de-gas with a small vent of air after unthreading two full turns and before three full turns are completed.

The cylinder valve can fly off with enough force to kill of the valve unscrews from the cylinder. LOOK at valve when removing cylinder.

STOP if the valve starts to unscrew from the cylinder. Screw it back on and contact the manufacturer for Instructions to repair.

WARNING NEVER OPERATE OR ADJUST THE LPRV2 WITH THE MAINTENANCE SET SCREW #12 LOOSE OR REMOVED.

NEVER ATTACH AN AIR SOURCE WITH THE LPR CAP #13 NOT FULLY INSTALLED WITH THE MAINTENANCE SCREW #12 FIRMLY INSTALLED. IF THE LPR CAP IS LOOSE OR REMOVED THE LPRV2 PISTON IS UNDER PRESSURE AND CAN TRAVEL AT VELOCITIES, WHICH MAY CAUSE PERSONAL INJURY TO THE USER OR BYSTANDERS.

MAINTENANCE & SERVICE:

Maintaining the Ninja LPRV2 for optimum performance requires occasional Piston Oring #7 replacement.

Replacing and silicone greasing oring #7 will solve a number of common air pressure regulation issues:

1. Inconsistent pressure output.

2. Slow loss of pressure while under pressure but not using the regulated air.

3. Slow recharging of set pressure.

4. Leaking from LPRV2 cap #13, LPR adjuster #11, LPR Maintenance set screw #12.

WARNING THE LPRV2 RESETTING PRESSURE RELIEF #1-4 IS NOT USER SERVICABLE. DO NOT REMOVE OR TAMPER WITH THE LPR PRESSURE RELIEF

DISASSEMBLY: Reference figure 2

1. Remove Air Source.

2. Using a 3/16” Allen (hex) key rotate the LPRV2 Adjuster #11 fully Counter Clockwise.

3. Using a 5/64” Allen (hex) key remove the LPRV2 Maintenance Access Locking set screw #12 by rotating Counter Clockwise using a flat, non-ball end of the Allen.

4. Rotate LPRV2 cap #13 Counter Clockwise to remove LPR cap and Adjuster.

5. Remove LPRV2 Main Spring #10

6. Remove LPRV2 Piston #9 by light pressing an Allen key through the center hole on the Air Source Attachment side (Figure 3: X)

7. Remove and replace oring #7, lightly lube the oring with silicone grease.
