OPERATING INSTRUCTIONS

Use only genuine ARO® replacement parts to assure com-

patible pressure rating and longest service life.

HEED ALL WARNINGS.

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. 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 qualified physi-

cian for immediate treatment of such injuries.

SERVICING. Before servicing or removing fluid hose or

valve from a unit that has been used, be sure to disconnect

air lines and carefully bleed pressure off of the system.

PREVENT FIRES. When pumping, flushing or recirculating

volatile solvents, the area must be adequately ventilated.

Keep solvents away from heat, sparks and open flames.

Keep containers closed when not in use.

CAUTION

The maximum working pressure for the auto-

matic dispensing valve assembly is 5000 p.s.i. (345 bar).

MAINTENANCE

With proper care, this unit will give long reliable service. To

maintain this performance, it should be “flushed 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 orifice 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)).
