will the unloader have the pressure preset?

 

Unloader - VRT3



ZWD4040 Comet Pump Triplex 4 GPM 4000 PSI
- includes an unloader, thermal relief valve, quick connect, chemical injector siphon hose, and garden hose inlet with stainless steel filter - 1 inch hollow shaft and universal fits Honda, Kohler and Lifan engines.


Question; When I receive my pump will the unloader have the pressure preset?

  • The unloader is not set exactly. 
  • The factory uses a default setting that is close to the performance of the 4000psi pump.
  • It is not a dependable default setting. 
  • Please always check the oil level and start the unloader in the counter-clockwise setting until you can test the system. 
  • You can increase the pressure by manually turning the adjustment knob clockwise until you reach the desired load on the engine. 
  • Do not exceed 4200psi.
