GENERAL DESCRIPTION Be sure to read the IMPORTANT SAFETY INFORMA- TION on pages 3 thru 6 before using this sprayer. Your SprayTECH sprayer is a powerful, easy to operate and easy to service machine. Since it operates on the airless principle, no air compressor is needed. Power is supplied by a 3/4 horsepower, TEFC electric motor.
HYDRAULIC PUMP For the hydraulic pump location, see Figure 1. It operates as follows: The electric motor is connected to the eccentric bearing, which is inside the hydraulic pump. The piston rests on the bearing. The movement of the bearing causes the piston to move up and down.
The outlet valve also contains a device to dislodge a stuck valve. Simply push the plunger button located on the side of the paint block before starting the pump. CAUTION The plunger button should never be pushed during operation as this may cause premature failure of the outlet valve.
SPRAY GUN The spray gun is connected to the sprayer by the paint hose. The gun will spray when the unit is running, the suction and return tubes are in the spray material, the priming knob is turned to the pressure control valve is adjusted, and the spray gun trigger is pulled back.

3. Loosen the tip nut slightly. Turn the tip guard about 1/16 turn counterclockwise from desired spray angle. See Figure 4. TIGHTEN WITH WRENCH FROM THIS POINT Figure 4.- Spray Gun Tip Guard Postion Before Tightening. 4. Tighten tip nut. The tip guard should now be in the proper position.
OPERATION START UP PROCEDURE 1. CHECK TO BE SURE THE MOTOR SWITCH IS OFF— play it safe. 2. LOCK SPRAY GUN—The spray gun will not spray when the trigger lock is locked. 3. CHECK THE HYDRAULIC OIL— The sprayerer was shipped with the proper amount of hydraulic oil in the hydraulic pump.

2. Avoid sharp bending and kinking of the paint hose. The paint hose and electric cord should be kept clear of traffic and sharp cutting edges or objects. 3. Use the lowest pressure possible when spraying. Too much pressure shortens equipment life. It also causes faster than normal wear on the spray tip.

SPRAY TIP PLUGGING The spray tip can be plugged by foreign matter and “skin” in the paint. Excessively large paint pigments can also plug the tip. If the tip becomes plugged while spraying, proceed as follows: 1. Lock spray gun trigger OFF so that the spray gun can't spray.
SHUTDOWN AND CLEANUP You should clean and oil your sprayer as soon as you finish a job. Do not store the sprayer unless it has been cleaned and oiled. When you shut down, clean up with water if you were using latex paint and clean up with solvent if you were using oil base paint.
SUCTION FILTER CLEANING The suction filter is located on the end of the suction tube. A clean suction filter gives full delivery capacity and a constant level of spraying pressure. Clean the suction filter as needed with a brush dipped in solvent. CHECKING OPERATION OF INLET VALVE See Figure 14 for location of inlet valve.

REPLACING DIAPHRAGM OR DIAPHRAGM PARTS The diaphragm is the only separation between the paint pump and the hydraulic pump. It pumps paint, but it also serves as a gasket between the hydraulic pump and paint pump. If the diaphragm membrane ruptures, paint will probably get into the hydraulic housing.
Provided you have followed the instructions, the sprayer will operate efficiently and give trouble-free service. Should any unexpected problem arise you can, in most cases, remedy the problem by following the chart below.

TROUBLESHOOTING (Continued) Problem Sprayer draws up paint, pressure builds up, but drops away markedly when gun is opened (low performance) Pressure fluctuation Paint in hydraulic housing Spray gun won't shut off Remedy Cause 1. Put on correct tip 1. No spray tip on gun 2.
TROUBLESHOOTlNG (Concluded) Problem Spray gun leaks Spray gun won't spray Low paint output from spray Spray gun sprays without trigger being pulled back NOTE1: If a return line that is completely submerged in paint causes bubbles after priming, you probably have a vacuum leak in the suction set.
