properly
Spraying capacity too low Turn the thumbwheel 4 towards setting 5
Clearance to target area too large Reduce spray distance
Not enough spray material on target area,
too few spray paths sprayed over target area
Apply more spray paths over target area
Spray material too viscous Dilute the spray material again and carry out
a test-spray run
Spray material runs off after
coating
Too much spray material applied Turn the thumbwheel 4 towards setting 1
Clearance to target area too close Increase spray distance
Viscosity of spray material too low Add original spray material
Spray material applied too often over same
spot
Remove spray material; reduce number of
spray paths over same spot
