OPERATING INSTRUCTIONS

Use only genuine ARO® replacement parts to assure com-



patible pressure rating and longest service life.
HEED ALL WARNINGS.



HIGH PRESSURE DEVICE. Improper usage of this
equipment could result in serious injury. The possibility of
injection into the esh is a potential hazard. Never allow
any part of the human body to come in front of, or in direct
contact with, the material outlet. An injection injury can be
serious. If injection should occur, contact a qualied physi­cian for immediate treatment of such injuries.
SERVICING. Before servicing or removing uid hose or



valve from a unit that has been used, be sure to disconnect
air lines and carefully bleed pressure o of the system.
PREVENT FIRES. When pumping, ushing or recirculating



volatile solvents, the area must be adequately ventilated.
Keep solvents away from heat, sparks and open ames.

MAINTENANCE

With proper care, this unit will give long reliable service. To
maintain this performance, it should be “ushed thoroughly”
with solvent immediately following each application period if
equipment is to be idle for a long period of time.

If material leakage occurs between valve housing (25)



and body (19), check gasket (24).
If material leakage occurs at orice of gun, check ball and



ball seat for dirt or foreign substance. Inspect ball and
ball seat (23).
If material leakage occurs around piston rod (21) in open-



ing of air cylinder head (13) check tightness of retainer
(15) or worn packings (17).
If air leakage occurs around the air cylinder, check for



damaged or worn “O” rings. (Indicated on the drawing
(12), (11), and (4)).
