Clean the gun only with cleaning solutions recommended by the manufacturer of the
spraying material, which do not contain any of the following constituents:
•
halogenated hydrocarbons (e.g. 1,1,1, trichloroethane; methylene chloride, etc.)
•
acids and acidiferous cleaning solutions
•
regenerated solvents (so-called cleaning dilutions)
•
paint removers
The above constituents cause chemical reactions with electroplated components
resulting in corrosion damage. WALTHER Spritz-und Lackiersysteme GmbH is not
responsible for damages resulting from this kind of treatment.
Caution
Never immerse the spray gun in solvent or any other cleaning solution as such
measure is very likely to affect the functional reliability and efficiency of the gun.
Do not use any hard, pointed or sharp-edged objects when cleaning the spray gun,
as the precision-made parts can be easily damaged and are likely to affect your
spraying results.
1. Dismantle the gun as described in section 6 Retooling / Repairs.
2. Clean the air cap and nozzle with a brush dipped in the recommended cleaning
solution. Air cap and nozzle should always be cleaned properly to make sure
they fit well together. Material residue, which might impair the airflow, is thus
avoided.
3. Clean, if necessary, the material duct.
4. Clean the gun body and all remaining parts with a soft cloth and the recommen-
ded cleaning solution.
5. Apply a thin layer of grease to the following parts:
•
Piston spring
•
O-ring of the piston
•
Material needle.
Use non-acidic, non-resinogenic grease and a brush. The spray gun is then
re-assembled in reverse order.

Disposal of Cleaning / Servicing Substances
Disposal of any such substances must be in accordance with all applicable local and
national regulations, directives and laws.
Warning
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.
