7. Troubleshooting Guide
Defaults
Possible Causes
Remedies
Uneven paint flow
Presence of air in the paint circuit
Dump the paint circuit
Paint flow rate too slow
Increase pressure at the pump or pres-
surised tank.
Impurities in the circuit
Verify the filters, then dump the circuit.
Lack of paint in the
paint tank
Refill paint tank
Paint too viscous
Verify the paint viscosity
The paint is not flowing or
only barely flowing upon
exiting the gun.
Nozzle clogged
Clean the nozzle
The nozzle needle does not retract
Verify the nozzle needle line
Clogged filters
Clean the filters
No pump pressure
Verify the pump
Paint too viscous
Verify the paint viscosity
Obstructed paint hose

ing.
Foreign body preventing the nozzle

The paint exits by the head
air holes.
Damaged cartridge
Change the cartridge
Damaged paint joint
Change the seal
Poor spray
Nozzle partially clogged
Clean the nozzle
Insufficient paint pressure
Increase the paint flow rate
Excessive viscosity
Dilute the paint
Lack of air in the spray
Increase the air pressure
Excessive paint flow rate
Decrease the paint flow rate
Nozzle damaged or worn
Change the nozzle
Orange peel effect
Evaporation of solvents too fast
Use heavier solvents
Paint droplets too large
Increase the spraying distance
Dilute the paint
Increase the paint pressure
Reduce the nozzle size
Increase the electrostatic effect
