Troubleshooting

Observe the safety instructions and maintenance instructions!
Problem
A The paint spray is
interrupted or
pulses
B Spray pattern is
incomplete
C Irregular paint
application with drip
formation
D Uneven material
accumulation
Cause
Hold the gun at an incline
Material cap is loose or dam-
aged
Viscosity is too high
Ventilation in cover or drip
guard (item 09 or 14) is
clogged
Air cap (item 11) dirty or dam-
aged
Paint sticks to the nozzle or
parts are damaged
Nozzle needle is damaged
Nozzle dirty or damaged
Working pressure (flow pres-
sure) too low
Viscosity is too high
Air cap (item 11) dirty
Working pressure (flow pres-
sure) too high
Slotted nozzle is loose or dam-
aged
Air cap and nozzle are clogged
with paint
Viscosity is too low
Compressor output too small
Spray width too great
Remedy
X
Guide the gun such that the ves-
sel is vertical
X
Screw the material cap tight or
replace the entire nozzle set
(item 10, 11, 12 or 13) (see Fig-
ure 3a-c)
X Decrease viscosity, use nozzle
set with larger diameter, correct
viscosity
X Clean (see Chapter 4, 5)
X
Clean (see Chapter 4, 5) or re-
place complete nozzle set (see
Figure 3a-c)
X
Clean (see Chapter 4, 5) or re-
place entire nozzle set (see

X Replace the complete nozzle set
(item 10, 11, 12 or 13)
X Clean (see Chapter 4, 5) or re-
place complete
(item 10, 11, 12
Figure 3a-c)
X Increase working pressure (flow
pressure) Observe
working pressure
X
Decrease viscosity or increase
material pressure (item 18)
X
Cleaning
X Decrease working pressure
X
Screw slotted nozzle (item 13)
on tightly or replace nozzle set
X
Clean (see Chapter 4, 5) or re-
place complete
(item 10, 11, 12
Figure 3a-c)
X
Increase viscosity, use nozzle set
with smaller diameter
X Use different output

rating
X
Reduce spray width (item 4)
