(1) non-conductive solvents are also called non polar solvents; conductive solvents are also called
polar solvents.
Before switching ON the electrostatic effect :
- Install the air cap assembly over the needle seat or tip and secure in position with retaining ring
onto the gun.
- After applying solvent onto the gun and hoses check they are completely dried.
- Check the cleaning solvent vapors due to the cleaning operation are totally evacuated.
Procedure
Turn the ON / OFF switch on the power supply and gun to OFF "O" (All indicator lights switch off).
Turn off the atomizing air shut off valve (E).
Fully screw clockwise the needle stop at the rear of the gun.
Trigger the gun until the atomizing air stops flowing from the front of the gun.
Empty all material from the container, then fill the material container with a solvent compatible with
the material just emptied.
Remove the air cap and tip from the gun.
Fully unscrew counterclockwise the needle stop at the rear of the gun (fluid passage open).
Decrease the air pressure on the pump air motor.
Trigger the gun to dispense solvent into a grounded waste container until the solvent is clean. If
necessary, increase the fluid pump air pressure.
When clear solvent flows from the gun, turn down the air pressure regulator (F).
Remove the fluid pump suction hose from the solvent. Go on to triggering the gun until the fluid
pump starts to overspeed denoting that all solvent has cleared the pump. Release the gun trigger.
Blow up the fluid hose with compressed air and reassemble the air cap and tip onto the spray gun.
GUN CLEANING METHOD RECOMMENDED
Never immerse the gun in solvent.
Do not use metal tools to clean the gun or the air cap holes, as they scratch them and create a
distorsion of the spray pattern.
Only use soft cloth or bristle brush.
Clean the front of the gun and the fluid nozzle with the gun pointed down, to prevent dirty solvent
from flowing back into the air passages.
AIR CAP CLEANING METHOD RECOMMENDED
Make sure that the fluid pressure has been released in fluid hose.
Remove the air cap ring and air cap from the spray gun.
Clean them with a soft brush and some solvent (do not leave these items immersed in solvent).
Blow up the air cap and air cap ring with compressed air.
After cleaning, store the air cap, tip, nozzle and needle seat or reinstall them onto the gun.
On KMX 3 Ex and KMC 3 Ex, check the electrode wire :
the wire is bent : straighten it.
the wire is broken or damaged : replace it.
Never start up a gun whose electrode wire is damaged or broken.
