Return the machine to its location. Examine
whether the glow bare is intact (do not switch on,
only visual check.) If necessary remove the elec-
tric case and pull back the rubber seal of the
glow bare to check for any penetrated liquid. In
this case you have to exchange the glow bare. Fill
the machine with water to make a test-run and
then replace the water with fresh FeCl3 according
to the description above.
The hydrochloric acid can be used later, in order
to dissolve Sludge sediments in etching agent.
Give HCl in portions of approx. 0.5l to the dirtily
brown etching agent and let the machine run
briefly. Do this so long, until the solution is to a
large extent clear again. But: NEVER give Hydro-
chloric acid to fresh iron-III-chloride! Dispose pos-
sible surplus of HCl with used etching agent.
This guidance represents only the fundamental
procedure in standard situations. Mistake and
change reserved. Handling the chemicals takes
at one`s own risk. Regard safety regulations!
Against FeCl3 marks on clothes, smooth and por-
ous surfaces we supply a highly effective stain re-
mover on organic basis.
Drain the dirty rinse water from floor drain of the
rinsing zone. The waste laws demand economical
handling of rinse water. We advise to collect the
water from the first rinse a) to compensate evap-
oration losses and b) for new FeCl3 solution!
After discharging the water sediment remains in
the basins. Take up mechanically and give these
to the used up etching agent. Dispose surplus
rinse water together with the used up etching
agent.
Motor:
we recommend to check the shaft sealing ring in
the PVC flange regularly or to exchange this shaft
regularly every two years. On request we send an
instruction on how to change this shaft ring.
9. Guarantee
All machines are submitted before distribution to
examination on tightness, function and continu-
ous operation firmness. On the machine we grant
a work warranty of 12 months to our customers
starting from purchase date on accuracy in ma-
terial and processing. We warrant at our choice
by exchange of incorrect parts or by repair of the
machine in our house. Old parts change into our
possession.
10. Disclaimer of Warranty
All parts subjected to wear and the heater ele-
ment are excluded from this warranty. Any direct
or indirect damage resulting from over-heat or
chemical reaction shall void all warranty claims.
This also applies to defects to the machine
caused by non-observance of this manual or of
parts of it.
We cannot accept subsequent claims from dam-
age or destruction of workpieces worked on in the
machine, because we have no knowledge or con-
trol over the operating conditions at your site. This
is valid in a general manner also for requirements
from damage to articles, buildings and persons
as well as the environment.
We do not warrant that the function of the ma-
chine will meet the customer's requirements or
that the operation of the machine will to this re-
gard be error free.
In no event will we be liable to the customer for
any incidental, consequential, or indirect dam-
ages of any kind, including loss of profit and pro-
secution for environmental pollution, even if we
could have been aware of the possibility of such
damages.
All information was arranged with great care. We
reserve ourselves however mistake and technical
changes without previous announcement.
