Electronic Crossover Operation

NOTE:

These instructions are for the display module func-

tions used on tandem systems. For basic ram and

pump operation, refer to the component manuals

supplied.

Pressure Relief Procedure

1. Lock the gun/valve trigger.

2. Press On/Off key . If system is On, display will

highlight . Select to turn off.

3. Turn off the air motor slider valve (BF) on both ram A

and B.

4. On both ram A and B, turn off the main air slider

valve (BA). Set the ram director valve (BC) to the

down position. The ram will slowly drop.

5. Unlock the gun/valve trigger.

6. 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.

7. Lock the gun/valve trigger.

8. On both ram A and B, open the fluid line drain valve

and/or the pump bleed port. Have a container ready

to catch the drainage.

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 your fluid with oil, flush the pump with a compatible

solvent before use. See your pump manual for flushing

directions.

Startup

1. On both ram A and B, turn on the main air slider

valve (BA). Set the ram director valve (BC) to the

down position. The ram will slowly drop.

2. Turn on the air motor slider valve (BF) on both ram A

and B.
