Apply needle regulator with counter nut 15 for quantity of fluid flow. Turning needle regulator right: less fluid flow. Turning needle regulator left: more fluid flow. • Pull trigger at the valve body 4. Spray operation starts. You will notice that you receive so called “pre-air” prior to opening fluid flow when pulling the trigger. When releasing trigger you still have “purging-air” after needle has closed, nozzle and fluid flow Has stopped. This prevents that the fluid forms drops instead of the desired atomization. 4.3 Shutdown • Hold up the finespray applicator. • Depressurize the pressure pot. The mold release agent flows back into the pressure pot. 4.4 Return to Operation • Pressurize the pressure pot. • Pull trigger at the valve body 4. Spray operation starts. The feedline will be filled. 8 5 Care and Maintenance 5.1 Care A Pay attention to the safety instructions in section 1.4 “For your Safety” Before servicing the spray applicator - Disconnect it from the material supply and - Release air pressure. Otherwise ejected elements can cause danger. To clean the applicator, spray solvent until pure solvent leaves nozzle. Do not submerge entire applicator in solvent. At longer working interruptions it is advisable to clean air cap and nozzle by putting these parts only into solvent. If necessary, use soft brush. To clean small drill holes, use our special nozzle cleaning needles (Sealing and Repair Kit 97730). Moving parts and threads should always be greased slightly. 5.2 Changing Nozzle A nozzle set includes needle 7, nozzle 3 and air cap 2. If nozzle size is to be changed, always change all three parts. Change the complete set also if only one of the parts is defect. * • Remove screw 14. • Pull out valve spring 11. • Pull out needle/valve cartridge. • Unscrew the protection ring 1, remove air cap 2. • Unscrew nozzle 3. • Re-assemble in reverse order. 5.3 Disassembling Valve-Needle • Remove screw 14. • Pull out valve spring 11. • Pull out needle/valve cartridge. • Unscrew valve lock 13. • Pull out needle spring 12. • Pull out needle 7. • Re-assemble in reserve order. Needle nuts 8 must be counter-screwed in such a position where “pre-“ and “purging-air” work. The correct position of needle nuts 8 on needle or extension needle is 8.8 - 9.0 mm from the end of the needle and both nuts are countered against each other firmly. That applies also if extensions are built-in additionally. 9 6 Troubleshooting Type of malfunction Possible causes Correction Drops form on the trigger - The needle gasket 5 is worn respectively loose and must slightly be retightened. • For that purpose remove needle/valve cartridge, see section 4.3. Then unscrew screw at the valve body 4 and take out needle driver (squared bolt). Using a small screw driver turn stuffing box 6 gently clockwise and try if needle is sliding smoothly again within the tightened gasket. Drops form on the nozzle - Either needle or nozzle is worn. - Needle is not closed properly e.g. because of particle residues within nozzle. • Replace needle or nozzle. • Clean the needle/valve cartridge with solvent, see section 5. There is an uneven and not steady spray jet - Dirt residue within air cap. - Nozzle is not correctly screwed in. • Clean air cap with solvent. • Make sure that nozzle is screwed in tight. Air blowing constantly although trigger is released. - O-ring 9 and/or washer 10 worn. - Needle nuts are not counter-screwed in correct position, see section 5.3. • Change O-ring and/or washer. Drops form on the extension at the applicator and/or the spray head. - O-rings are worn. • Change O-rings, see section 7.2. 10 7 Annex 7.1 Spare Parts Finespray Applicator 97715/97725 HS^ For the table below see illustration on page 6.
