Spray Starting and Adjusting

WARNING

If there are leaks, shut off the pump immediately and release system pressure follow the “Pressure Clearance Procedure” then tighten connections, start the pump again and check to be sure leaking has stopped.

Always use the lowest air pressure necessary to get the desired results, higher pressure waste fluid and cause premature wear of the pump packing and spray tip.

Never operate the pump to run dry of the fluid being pumped because a dry pump will quickly accelerate to a high speed, possibly damage itself.

If the pump accelerates quickly or running too fast, shut off immediately and check the fluid supply.

NOTE:

The pump will stall out (stop) against pressure without damage to the pump.

Always follow the “Pressure Relief Procedure” before cleaning, , or, removing the equipment or servicing any part of system equipment.

•Immerse the pump intake or suction tube in paint.

•Make sure drain valve is open.

•Let the pump run until it is primed and run until paint flows smoothly out of prime / drain valve.

•Close the prime

•Squeeze the gun trigger and open the on-off air valve gradually at first to from the gun, without spitting, release the trigger and open the pump runaway valve fully.

•Tighten the tip retainer nut with moderate tension only.

•If pattern is not fully atomized, gradually increase the pressure with the pump adjusting nut.

•Adjust the pump to the minimum pressure required to obtain the desired spray pattern of paint. If atomization is not possible on thick paints,

thin with the compatible solvent.

•Use the lowest pressure setting possible.

•If the pump accelerates quickly or is running too fast, stop the pump immediately and check the mate- rial supply tank.

•Don’t leave a pump shut off if the material supply has been exhausted and air has been pumped into the lines.

•Prime the pump and lines with material or flush and leave filled with solvent, with pressure relieved.

MAINTENANCE

DAILY SHUTDOWN PROCEDURE

•Shut off power to engine.

•Close hydraulic ball valve.

•Always bleed off paint pressure in the system by triggering the gun open and opening the drain valve and have a container ready to catch the paint draining from the drain valve.

•Remove the tip from the gun and clean and leave it in solvent until ready to use again.

•Do not disconnect the gun or hoses and keep the unit filled with coating to reduce the need for flushing.

NOTE:

−When using fast drying paints, immerse the suction tube in a container of solvent during shutdown periods.

−Clean the pump’s intake screen.

SHUTDOWN FOR STORAGE

Always follow the “Pressure Clearance Procedure” and when storing the unit : proceed as follows.

•Flush the unit clean, as instructed above. Sometimes it takes several flushings, each with solvent, to clean thoroughly.

Flush the pump, hoses, and gun with full of solvent unless the flushing solvent is water or ketone solvent, to remove water or ketone solvent, fill the system with min- eral spirits solvent or light oil for long storage periods, and wipe all external wetted parts with oil. Also remove water or ketone solvent used, from exposed part of pump displacement rod.
