  • FWD:The inverter is co-rotating work.
  • REV:The inverter is work reversely.

2) Monitor operation specification

When the converter is operating, press “DATA” button, “▲” button or “▼” button to observe current or running frequency.

3) Simple operation

Observe specification: set “F039” to 0, “F040” to 25.00. Under this condition, potentiometer works.

  • Flow adjusting button
  • Knob jam nut
  • Spray head jam nut
  • Cone angle adjusting spray gun head
  • Atomization adjusting button
  • Jam nut
  • Liquid blasting inlet
  • Coating liquid inlet
  • Shoot fire inlet
  • How to use the spray gun
  • Flow control: Loose (4) knob jam nut at clockwise and adjust (3) flow adjustment button at counterclockwise to increase flow. After adjusting, lock (4) knob jam nut.

Use distilled water or ethanol to clean spray gun, liquid barrel and pipe.

If coating liquid isn’t sprayed, please check: A. The liquid switch of the electric control cabinet; B. Whether the compressed air is purified (it is better to install cleaner in the air pump outlet); C. Whether the coating liquid is mixed evenly; D. Whether the spray gun is locked when adjusting atomization cone angle.

If crevasse occurs, please disassemble the following accessories: flow adjustment button→ spring→ tag pin→ spray head jam nut→ cone angle adjusting spray gun head. Use fine needle to clean spray head hole or use compressed air to blow-back.
