Binks Comet air-assist 4/12 start up

ITW Binks AIR- ASSISTED AIRLESS start up & Maintenance

· Main air supply in enters from the front of the regulator set

· Red Poly hose is for gun atomizing air and should attach to the regulator on your left and to the Handle of the AA-1500 Gun (atomizing air)
· Blue High pressure fluid hose attaches to the pump fluid section outlet fitting and than to the inlet filter that is attached to the tube going to the front of the gun.
· Fill the pump solvent cup with supplied pump Lub. This cup should always have Lub in it to keep the pump rod lubricated, which will extend packing life.
· Run clean solvent thru Pump when starting up for the first time.
· Start Pump with both the regulators knobs backed off to 0 LBS, main line air into unit at about 80-100 LBS, Put the fluid material tube in material or solvent to be sprayed.
· Remove air nozzle and fluid tip from Gun.
· Turn the RIGHT knob up until Pump starts to cycle. Once pump start to cycle, Hold the trigger of the gun open facing back into the material bucket (point at the side of the pail so that material does not kick back at you) Continue to hold the gun open until a steady flow of material is coming out of the gun. Once you have a steady flow release the trigger. The pump should stop shortly after you let go of the trigger.
· Every spray tip should have a tip gasket mounted inside the back of the tip, ALWAYS DOUBLE CHECK TO MAKE SURE THIS GASKET IS IN PLACE BEFORE PUTTING TIP AND AIR NOZZLE BACK ON THE GUN. Place tip and air nozzle on the gun, this should be hand tight.
· Note: all materials that you may spray are different and may require different pressures, or even different tips depending on your final finish needs and the speed you would like to go. Please Note in order to control your over spray you should always spray at the lowest possible pressure to get the job done at the speed you want to go.
· A good starting point for the fluid pressure (RIGHT Knob) is about 30 LBS. The right knob will control how even the inside of your spray pattern will be or over all atomization. The LEFT knob is for shaping air and controls the outside part of your pattern start with this pressure at about 10-20 LBS.
These pressures will increase depending on the materials to be sprayed. Most wood finishers end up between 35 and 50 lbs on the right knob and 10-15 on the left knob. Using a 11 or 13 tip. It is the tip Size that increases the speed that you want to spray at. Pressure improves quality of the finish.

Clean up and Maintenance
· If you spray the same material everyday and the material has a pot life of 5 or more days. You can leave material in the system UNDER PRESSURE to be sprayed the next day. At this point it is suggest that you leave the pump rod in the down position to keep air from getting into the system. The Gun Air Nozzle and Tip should be removed and cleaned in solvent (be careful to not loose the tip gasket) and then with a clean solvent rag wipe down the gun and Lubricate the Needle assembly in front of the trigger (Vaseline is good for this). It is also recommend that the filter at the gun Inlet tube be cleaned at least every other day that you spray.
· If you do not spray everyday, use a material with a short pot life, change colors or change coating the system will have to be cleaned at every use. To do this start by Backing off the RIGHT knob (Air to the gun is not needed to clean the system) pull the pickup tube out of the coating being used and please into a container with the proper solvent to clean out the system, Take air nozzle and fluid tip off the gun, being careful not to loose the tip seal, Back off the RIGHT knob to about 20 LBS on the pump, Point gun into a waste pail and pull the trigger (be careful here, you will get a surge in pressure when you first pull the trigger) continue to let material run thru the system until clean solvent come thru the system. Once you have clean solvent put the tip and Air nozzle back on the gun and then spray some clean material thru the tip. At this time take the nozzle back off the system. Turn the air supply off to the pump, Pull the trigger on the gun to release the pressure, once all the pressure is drained off it is now safe to clean or replace the fluid filter at the handle of the gun. Once this is completed the system can now be re-charged with solvent or a new coating.
· The system should never be left for long periods of time dry. If you are not going to be using the system it should be left wet with the proper solvent under pressure with the piston rod in the down position.
· Before using the system again Make sure you have pump lub in the solvent cup of the pump and make sure the Tip Gasket is in place.


Special Note: The Binks Raptor Pump is a 18:1 Ratio high pressure pump
Every 10 lbs in = 180 LBS out ( most shop run this pump at 40-60 lbs on the pump side and 15-20 Lbs on the air side)



Good luck and enjoy the use of your new investments. Fell free to call with any issues you may have.
