Protective equipment:
The selection of the protective equipment depends on the maintenance conditions on site and the
medium utilized by the system owner. The applicable country-specific safety, accident prevention,
occupational safety, and environmental protection regulations must adhered to for the proper
selection of the protective equipment and the information given by the spray media manufacturer
on the safety data sheet must be taken into consideration.

General maintenance information
Check wear parts such as fluid nozzle, valve seat screw, threaded needle, seals, and cup collars
as well as springs in adequate intervals and replace the parts if necessary, for example if the
threaded needle does not close properly or if coating material leaks uncontrollably.
NOTICE!
Other than for repair and maintenance purposes, the hand-held spray gun will not be com-
pletely disassembled. For cleaning as well as for material changes, you thoroughly flush it
with a cleaning agent as recommended or stipulated by the supplier of the coating material
until the discharged cleaning product is clean.
Never fully immerse the hand-held spray gun in a cleaning product! There is a risk that seals
will be damaged and lubricants will be washed out.
Do not clean fluid nozzles or the valve seat screw with hard, sharp-hedged objects. A special
flat brush as well as various nozzle cleaning needles made by Krautzberger GmbH are rec-
ommended for cleaning purposes.
In case of prolonged operational interruptions, allow the hand-held spray gun to air-dry after
flushing it with cleaning product and store it at a suitable location until it will be used again.
A cloth soaked in cleaning product is recommended for exterior cleaning.
