Material Disposal
Contaminated diluting agent, remnants of spray material
and, if applicable, remnants of diluting agent must be dis-

ner. Observe the manufacturer's disposal information and
the local regulations for disposal of hazardous waste.
Chemicals harmful to the environment may not be disposed
of into soil, groundwater or bodies of water. Never pour
Troubleshooting
Problem Cause
Spray material does not Spraying capacity too low
cover properly
Clearance to target area too large
Not enough spray material on target area, too
few spray paths sprayed over target area
Spray material too viscous
Spray material runs off after Too much spray material applied
coating
Clearance to target area too close
Viscosity of spray material too low
Spray material applied too often over same
spot
Atomisation too coarse Spraying capacity too high
Air flow too low
White nozzle cap (10) mounted (nozzle dia-
meter too large)
Nozzle needle (15) contaminated
Spray material too viscous
Air filter (30) heavily contaminated
Excessive paint mist Too much spray material applied
Air flow too high
Clearance to target area too large
Spray jet pulsates Not enough spray material in container
Ventilation hole (18) on suction tube (17)
clogged
Suction tube (17) loose
Container seal (16) not positioned or not cor-
rectly positioned in groove of suction tube (17)
Nozzle cap (10)/(11)/(12) loose
Air filter (30) heavily contaminated
Spray material too viscous
Spray material dripping at Deposit of spray material on the nozzle

Storage
– Before putting the fine-spray system into storage, thor-
oughly clean the fine-spray system and allow all parts to
dry completely before assembling them.
Corrective measure
Turn the thumbwheel (4) towards setting 5
Reduce spray distance
Apply more spray paths over target area
Dilute the spray material again and carry out a
test-spray run
Turn the thumbwheel (4) towards setting 1
Increase spray distance
Add original spray material
Remove spray material; reduce number of
spray paths over same spot
Turn the thumbwheel (4) towards setting 1
Turn the air flow control (25) to the right
Mount the grey nozzle cap (11) or the black
nozzle cap (12)
Clean nozzle needle
Dilute the spray material again and carry out a
test-spray run
Change air filter
Turn the thumbwheel (4) towards setting 1
Turn the air flow control (25) to the left
Reduce spray distance
Refill spray material
Clean the suction tube and the ventilation hole
Slide the suction tube all the way onto the paint
channel (19)
Mount the container seal precisely all around in
the suction tube groove
Tighten the nozzle cap
Change air filter
Dilute the spray material again and carry out a
test-spray run
Clean the nozzle cap, nozzle needle and air cap
Tighten the nozzle cap
