Attention
Do not use any hard or pointed objects for cleaning. Otherwise, precision parts of the
spray gun can be damaged and spraying results degraded.
Use only those cleaning materials for cleaning the spray gun which have been
prescribed by the manufacturer of the spraying material and which do not contain the
following components:
• halogenated hydrocarbons (e.g. 1,1,1, trichloroethane, methylene chloride, etc.)
• Acids or acidic cleaning agents
• Solvents or cleaning thinners
• Varnish removers.
The constituents named above cause chemical reactions on galvanised components
and lead to corrosion damage.
WALTHER Spritz- und Lackiersysteme GmbH will not honour warranty claims for
damages resulting from such treatment.
Clean the spray gun
• before each material change
• at least once a week
• several times a week, depending on the material and the degree of contamination.
In this manner, the safe functioning of the spray gun is maintained.
1. Dismantle the gun as described in 5.1/ 5.2 Replacing the material nozzle and
needle.
2. Clean the air head and the material nozzle with a brush and the cleaning agent.
3. Clean all other components and the gun body with a cloth and the cleaning
agent.
4. Apply a thin layer of grease to the following parts:
• Material needle
• Needle spring
• All sliding parts and bearing points
• Grease the movable inside parts at least once a week.
• The springs should always be coated with a thin grease film.
Use WALTHER PILOT gun grease and a brush for this purpose. The spray gun must
subsequently be reassembled in reverse order.
