Do you have a question about the JS-HH15A and is the answer not in the manual?
Questions and answers
I have setup as per direction s however it is not spraying
The JS-HH15A spray gun may not be spraying due to several possible reasons:
1. Incorrect Suction Tube Position – Ensure the suction tube is properly aligned. If spraying overhead, turn the tube rearwards; if spraying on a flat surface, turn it forwards.
2. Thick Paint or Clogged Nozzle – If the material is too thick, dilute it by 5-10% step-by-step until the flow rate meets requirements.
3. Low Convey Capacity – If the spray output is too low, gradually add dilution to improve flow.
4. Power Supply Issue – Ensure the mains supply voltage matches the rating plate (230-240V).
5. Blocked or Dirty Components – Clean the spray nozzle and suction tube to remove any obstructions.
Checking these factors should help resolve the spraying issue.
