When releasing or tightening a nozzle on an SG-44 spray gun, secure 
it with an SW17 wrench to prevent any strain on the hose. 

 

 

CAUTION! 

Allow the Loctite 243 to harden for at least six hours to achieve an 
optimal  result.  Not  observing  the  hardening  period  can  lead  to  the 
adhesive being washed off by the water jet. 

 

 

Maintenance 

Maintenance  and  repair  work  may  be  performed  only  by  persons  who  have  been 
trained to do repairs on high-pressure systems. Use only accessories and spare parts 
that  have  been  approved  by  enz®  technik  ag.  Use  only  high-pressure  components 
(hoses, couplings, etc.) that are permitted for the respective pressure and temperature 
range. 

 

Inspections  

Inspect  the  valve  parts  (seal  seat,  o-rings,  support  rings,  ball,  piston  rod,  pressure 
piece) after 1,000 operating hours or one year or, if using hot water (over 90 °C) or 
chemicals, after 500 operating hours or six months for damage and replace parts as 
necessary from the repair set (see 8.2).
