Maintenance/Cleaning
Changing of the etching agent
The etching agent is discharged over a ball valve, which is under the machine body. As described
above, you have access to the etching chamber when you remove the cover. This makes it easy to
remove any sediments manually. If you use ferric-III-chloride and consider the following proposal,
you can change the etching agent without large cleaning expenditure: With increasing saturation fer-
ric-III-chloride tends to deposit surplus cuprous salts as mud. The solution changes its colour from a
initially transparent to a milky green-brown. At this time usually the etching time doubles in compar-
ison to the beginning. If you change the etching agent at this time, then the mud formation can be
stopped and mud already set off will be brought back into solution.
Dismantling
For cleaning and repair works, it may be necessary to dismantle the inner parts of the spray cham -
ber. To do this, follow these steps:
1. Remove the lid frame
4. Dismount the sieve
2. Remove the board
holder from its hinge
5. Discharge the
etching or developing
liquid
3. Lift the lid of the spray
chamber
6. Now you have ac-
cess to e.g. the etch-
ing nozzles adjust-
ment
