Rock Regulator Manual

ROCK Regulator:


Installation is actually pretty simple.

Disconnect the existing regulator (slide back the retaining collar, then pull or pry the hose from the fitting). You will most likely damage the existing hose. A new one has been provided. It is a tight fit going back on but it will fit. Note the position of the hose fitting. You will want to have the fitting on the new regulator pointing the same direction. Using the proper wrench, unscrew the old regulator and set aside. Be sure to clean the port of residue before installing your new regulator in order to avoid contamination of the internals.


Install the “Rock” with a 7/16” wrench. Tighten securely, making certain the hose fitting is in the proper position. DO NOT over tighten. Re-install the airline to the new regulator and the job is complete. We dubbed the regulator “Rock” because it is “steady like a rock” and it should seldom need to be adjusted, if at all.


Adjusting the “Rock”: You will use the same 3/16” Allen wrench used to adjust the velocity. Turn the Allen screw clockwise to increase operating pressure and counter clockwise to decrease pressure. Increase pressure slowly until the gun begins to cycle fully (lowest operating pressure). Then add ¼ to ½ turn in the summer and add ¼ turn for colder climates. This should get you into or real close to your guns’ operational SWEET SPOT. Find that SWEET SPOT and leave it there. You may find that you will never have to adjust the pressure regulator again.


IMPORTANT NOTE: Basic lubrication is required for long-term service from your pneumatic equipment. The easiest way to lubricate the insides of your paintgun is to add a little oil to the air supply input of your paintgun. This will lube the entire insides of the equipment and any excess will just pass through when cycled. It’s best to remove the barrel of your ‘cocker when lubing it to avoid excess oil in the barrel.


A pressure relief system is incorporated into the “Rock” to protect the other components and pressure lines of the automation system. The pressure relief will activate whenever a TOO-HIGH pressure condition exists in the system (approximately 250 psi). The pressure relief valve opening allows gas/air to vent out through the hole next to the adjusting screw of the regulator until it is adjusted properly or the CO2 supply is removed. The pressure relief system will re-set when the pressure is lowered to proper levels.
