OPERATING AND SAFETY PRECAUTIONS

Read and heed all Warnings, Cautions, and Safety Precau= tions before operating this pump.

Use only genuine ARO replacement parts to assure compat= ible pressure rating and longest service life.

WARNING MISAPPLICATION HAZARD DO NOT USE A REGULATOR WHERE THE FLUID INLET PRESSURE IS TOO HIGH FOR THE DESIGNED OPERATING RANGE.

WARNING HIGH PRESSURE DEVICE. IMPROPER USAGE OF THIS EQUIPMENT COULD RESULT IN SERIOUS INJURY. The possibility of injection into the flesh is a potential hazard. Wear approved safety glasses or face shield any other equipment as needed to prevent injury. Never allow any part of the human body to come in front of or in direct contact with the material outlet, the tip, or the material outlet of the dispensing device. An injection injury can be serious. If an injection acci= dent should occur, it is very important that you contact a quali= fied physician for immediate treatment.

WARNING COMPONENT RUPTURE. DO NOT OPER= ATE REGULATOR AT AN INLET PRESSURE GREATER THAN SPECIFIED. To avoid possible damage or personal injury DO NOT operate this unit at pressure higher than the stated oper= ating range as appears on the model plate.

WARNING HAZARDOUS AIR PRESSURE. CAN RE= SULT IN SERIOUS INJURY. DO NOT SERVICE OR CLEAN PUMP, HOSES OR DISPENSING VALVE WHILE THE SYSTEM IS PRESSURIZED. First disconnect air line, then relieve pres=

sure from the system by opening dispensing valve or device and/or carefully and slowly loosening and removing outlet hose or piping from pump.

WARNING DISASSEMBLY HAZARD. DO NOT DISAS= SEMBLE THIS REGULATOR WHEN IT IS UNDER PRESSURE. RELIEVE ALL MATERIAL PRESSURE IN THE PUMPING SYS= TEM BEFORE ATTEMPTING SERVICE OR DISASSEMBLY PROCEDURES. Disconnect air lines and carefully bleed off of the system. Be certain the system is not maintaining pressure due to a material restriction in the hose line, dispensing de= vice, or the spray or extrusion tip. Failure to relieve pressure both up stream and downstream may result in an injury upon disassembly.

WARNING BONNET REMOVAL HAZARD. DO NOT AT= TEMPT TO REMOVE THE BONNET RETAINING BOLTS WITH= OUT FIRST RELIEVING THE TENSION ON THE MAIN SPRING. Failure to relieve tension could result in an accident upon dis= assembly.

WARNING PREVENT FIRES. KEEP SOLVENTS AWAY FROM HEAT, SPARKS, OR OPEN FLAME. Keep containers closed when not in use. When pumping, flushing or recircu= lating volatile solvents be certain the area is adequately venti= lated.

CAUTION FLUSH SUPPLY LINE. Before installing fluid regulator blow the supply lines clear and flush to remove con= taminates.
