MAINTENANCE AND CLEANING

1. 

Pressure air free of water, oil and mechanical impurities must be 

used for the gun control.

2. 

Do not let the NH dry-up in the gun and/or surface. Removal of 

the dry-up HN is difficult and it can result in damage of smooth 

surface of the part and thus more difficult next cleaning (NH is 

easy collected on the damaged surface). Cleaning must be done 

by washing with proper solvent, not by immersion into the gun, 

as it can adversely affect function and operation life of the gun.

3. 

When the high-pressure nozzle hole is clogged, do not clean it 

by any metal objects, such as wires, pins, use instead special 

cleaning wires, or clean the device acc. to instructions specified 

in section „Operation“, point 4.

4. 

When the NH with rough pigments is sprayed, it is necessary to 

check the sealing of the closing needle at least once in the shift; 

the leak results in discharge of the NH from the hole between 

front  and  back  section  of  the  gun  body.  When  the  NH  leaks 

from the hole, the gun must be disassembled and the sealing 

module, resp. worn needle must be replaced. 

 

»

The replacing is performed as follows: Unscrew the body with 

carbide  seat  (15).  Unscrew  the  stop  nut  (10)  from  the  back 

section  and  remove  the  spring  (7).  With  the  supplied  key 

unscrew the closing needle (14), secure the opening needle (6) 

by  the  key  in  the  back  section.  Remove  the  opening  needle 

with the piston backward. Disassemble the 4 screws (11) and 

separate the front section from the back one. Press the sealing 

module (12) out by means of the supplied key. Upon cleaning of 

the sealing module area the disassembly is completed. Visually 

check the needle for damage in the contact area with the sealing 

elements of the sealing modules, resp. replace the needle for 

the  new  one.  Assembly  of  the  new  sealing  modules  requires 

skills  and  care  to  prevent  cutting  of  both  sealing  O-rings  of 

the modules. Apply the machine oil to the module and press it 

carefully completely into the gun body. Apply the machine oil 

onto  the  needle  with  piston,  insert  it  carefully  from  the  back 

side to both sealing modules - do not apply force. Assemble the 

other parts in reverse order specified in the previous section.

5. 

Disassembly of the individual gun parts, even if it is easy, shall 

not be performed often and needlessly. The assembly works can 

be done with common maintenance tools and supplied special 

key.  Replacing  of  spare  parts  of  the  gun  must  be  assigned 

exclusively to the qualified maintenance staff.

6. 

Keep the gun and other accessory in perfect cleanness, as it is 

crucial for fault-free operation.
