What to do if my Graco Construction Equipment shows no dots or poor dots with ghosting?
- C
  Chad HamiltonSep 23, 2025
  If your Graco Construction Equipment shows no dots, the solenoid cartridge bar is too far away from aerosol marking can spray tip. If there are poor dots or dots with ghosting, the solenoid cartridge bar is too close to the aerosol marking can spray tip. In both cases, do Auto-Layout Can Actuator Adjustment. Also, the engine speed must be greater than 2600 rpm. Check that the aerosol can sprays, and replace it if not. Finally, replace the solenoid module if it is malfunctioning.

  The clutch on your Graco Construction Equipment may squeak when it engages because the clutch surfaces are new and not yet matched to each other. This noise should dissipate after a day of run time as the surfaces wear into each other.
