GB Operating manual ProSpray 3.21 Airless high-pressure spraying unit Models: 0558019 0558046 Original operating manual ProSpray 3.
GB Warning! Attention: Danger of injury by injection! Airless units develop extremely high spraying pressures. 1 Never put your fingers, hands or any other parts of the body into the spray jet! Never point the spray gun at yourself, other persons or animals. Never use the spray gun without safety guard. Do not treat a spraying injury as a harmless cut. In case of injury to the skin through coating materials or solvents, consult a doctor immediately for quick and expert treatment.

Safety Regulations 1. Safety regulations for Airless spraying 1.1 Explanation of symbols used GB • This manual contains information that must be read and understood before using the equipment. When you come to an area that has one of the following symbols, pay particular attention and make certain to heed the safeguard. HAZARD: High Pressure Hose The paint hose can develop leaks from wear, kinking and abuse. A leak can inject material into the skin. Inspect the hose before each use.
GB • • • Safety regulations 1.2 Follow material and solvent manufacturer’s warnings and instructions. Be familiar with the coating material’s MSDS sheet and technical information to ensure safe use. Use lowest possible pressure to flush equipment. When cleaning the unit with solvents, the solvent should never be sprayed or pumped back into a container with a small opening (bunghole). An explosive gas/air mixture can arise. The container must be earthed.

GB Solid Green When the pressure indicator is solid green, the sprayer is operating between 12 MPa (120 bar) and 23 MPa (230 bar). A solid green pressure indicator means: • The sprayer is at the proper pressure setting for spraying oilbased and latex house paints • The sprayer is operating at peak performance at a high pressure setting • If the pressure indicator goes to solid yellow when the pressure is set so that it starts at solid green, it indicates one of the following: a.
GB Starting operation 4.5 Spraying technique 5. Cleaning preserving agent when starting-up of operation initially Immerse the suction tube (Fig. 6, Item 1) and return hose (2) into a container with a suitable cleaning agent. 2. Turn the pressure control knob counterclockwise (3) to minimum pressure. 3. Open the relief valve (4), valve position PRIME (k circulation). 4. Switch the unit (5) ON. 5. Wait until the cleaning agent exudes from the return hose. 6.
Handling the high-pressure hose 6. GB Handling the high-pressure hose 8. The unit is equipped with a high-pressure hose specially suited for piston pumps. The high-pressure hose is to be handled with care. Avoid sharp bends and folds: the smallest bending radius is about 20 cm. Do not drive over the high-pressure hose. Protect against sharp objects and edges. Never pull on the high-pressure hose to move the device. Make sure that the high-pressure hose cannot twist.
GB Cleaning the unit (shutting down) 8.2 i Suction filter 8.4 1. 2. A clean suction filter always guarantees maximum feed quantity, constant spraying pressure and problem-free functioning of the unit. 3. Cleaning Airless spray gun Rinse Airless spray gun with an appropriate cleaning agent. Clean tip thoroughly with appropriate cleaning agent so that no coating material residue remains. Thoroughly clean the outside of the Airless spray gun. Intake filter in Airless spray gun Disassembly (Fig. 9) 1.
GB 9. Remedy in case of faults Remedy in case of faults Type of malfunction A. B. C. D. E. F. G. Unit does not start Possible cause Measures for eliminating the malfunction 1. No voltage applied. 1. Check voltage supply. 2. Pressure setting too low. 2. Turn up pressure control knob. 3. ON/OFF switch defective. 3. Replace. 1. Relief valve is set to SPRAY (p spray). 1. Set relief valve to PRIME (k circulation). 2. Filter projects over the fluid level and sucks air. 2.
GB Servicing 10. Servicing 10.1 General servicing 11.2 1. 2. Servicing of the unit should be carried out once annually by the WAGNER service. 1. Check high-pressure hoses, device connecting line and plug for damage. 2. Check the inlet valve, outlet valve and filter for wear. 10.2 11. 1. 2. 3. 4. 5. 6. 7. Remove the four screws in the front cover and then remove the front cover. Switch the unit ON and then OFF so that the piston rod is positioned in the lower stroke position. 3.

It is not necessary to remove the outlet valve. Unscrew both cylinder head screws (Fig. 13, Item 1) from the pump manifold (2) with a 3/8 inch hexagon socket head wrench. Slide the pump manifold (2) and piston (3) forward until the piston is out of the T-slot (9) on the slider assembly (4).

Position the pump manifold (2) underneath the gear unit housing and push up until it rests against the gear unit housing. Attach pump manifold (2) to the gear unit housing. Screw pump manifold (2) tightly to gear unit housing. Lubricate O-ring (Fig. 11, Item 6) between pump manifold (2) and inlet valve housing with machine grease.
GB 12. Appendix 12.1 Selection of tip Appendix To achieve faultless and rational working, the selection of the tip is of the greatest importance. In many cases the correct tip can only be determined by means of a spraying test. Some rules for this: The spray jet must be even. If streaks appear in the spray jet the spraying pressure is either too low or the viscosity of the coating material to high. Remedy: Increase pressure or dilute coating material.
