cesses, the nozzle tip and the gap in the air cap should be cleaned after the marking
process (as a function of the spraying material used). For this automatic cleaning
cycle, the marking device must be equipped with the V 2036900100 scouring device.
1.
Start the round jet air of the spray gun.
2.
Set at the scouring device;
• the spraying air for the couring agent of approx. 1.5 - 2 bar (it has adjusted
minimum 0.5 bar higher than the round jet air of the spray gun.
• the material pressure of the couring agent approx. 0.8 - 1.0 bar (depends
upon the material).
3.
An air/scouring agent mixture generated in the spray gun is fed through a scou-
ring channel (integrated in the individual gun and the block system) for some
seconds. (The time depends upon the spraying material used).
4.
After this, compressed air (approx. 2 -2.5 bar) is sent through for some seconds
(approx. 10 - 15 sec.), with the result that the residue of the scouring agent is
blown out. The precise actuation of the scouring and drying times must be done
on the customer's system control unit.
5.
Close the round jet air of the spray gun.
All pressures should then be removed from the complete spraying system until the
next operation.

Troubleshooting and Corrective Action
Warning
Prior to any servicing and repair work: Make sure that the spray gun is in unpressu-
rized condition, i.e. all air and material inputs must be shut off - if not, imminent Risk
of Injury.
Fault
Material nozzle or needle is dama-
ged
Material nozzle or needle is soiled
Gun is dripping
Piston spring (item 13) is broken
Packing Screw (item 3) too tight
Material leaks behind
Needle seal (item 4 ) damaged
the needle seal
Spray jet pulsating
Level in material tank too low
Spray jet is one-side
Air cap (item 1) is dirty

Pay special attention to all processing specifications and warnings issued by the
manufacturer of spraying and cleaning media. The improper disposal of any toxic
waste material represents a serious thread to to environment, i.e. to the health of
mankind and animal life.
