To clean the extrusion gun cleaning solutions that are specified by the manufacturer
of the extrusion material and do not contain the following ingredients:
•
halogenated hydrocarbons
(eg 1,1,1, trichloroethane, methylene chloride, etc.)
•
Acids and acidic detergents
•
regenerated solvents (so-called cleaning dilutions)
•
Paint stripper.
The above-mentioned Constituents cause electroplated components, chemical
reactions and lead to corrosion damage.
For damages resulting from such treatment, WALTHER PILOT makes no warranty.
Clean the extrusion gun
•
before any material change
•
at least once a week
•
depending on material and depending on the degree several times a week.
This will give you the safe function of the extrusion gun.

Turn off the extrusion pressure before cleaning the system (see 5.2 Starting and
shutting down).
1.
Disassemble the pistol as described in 5.5
extrusion gun retooling.
2.
Clean the fluid tip with a brush and cleaning agent.
3.
Clean all remaining parts and the gun body with a cloth and detergent.
4.
Lubricate the following parts with a thin film of grease:
