5.1  Care 

 

 

 

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.
