Before Operating

NOTICE

To prevent mixed material from fully curing in the system requiring replacement of all parts containing cured material, always be prepared to immediately begin flushing at the first sign of material curing in the system and immediately after spraying stops. See Flush on page 12.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment.

1.Lock the gun/valve trigger.

2.See FIG. 2, page 6.

a.Close the air motor ball valve (BF) and the main air slider valve (BA).

b.If the RAM is in a raised position, set the ram director valve (BC) to DOWN. The ram will slowly drop.

c.Jog the director valve up and down to bleed air from ram cylinders.

3.Unlock the gun/valve trigger.

4.Hold a metal part of the gun/valve firmly to the side of a grounded metal pail, and trigger the gun/valve to relieve pressure.

5. Lock the gun/valve trigger.

If you suspect that the spray tip/nozzle or hose is com- pletely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose.

Flush Before Using Equipment

The pump was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contaminat- ing fluid with oil, flush the pump with a compatible sol- vent before use. See Flush on page 12.

NOTICE

Prolonged exposure to solvent will reduce the life of the wiper. For maximum performance, do NOT soak platen soft parts in solvent. Instead, gently wipe down soft parts with solvent.
