Retooling and repairs

Warning
Prior to any repairs or replacements: Make sure that the spray gun is in depressu-
rized condition, i.e. all air and material inputs must be shut off - if not, imminent
Risk of Injury.
Note
In order to perform the following procedures, please refer to the exploded diagram
at the beginning of these operating instructions.

Replacement of the material nozzle and the air cap

1. Unscrew the air cap (item 2) from the material nozzle (item 4).
2. Unscrew the material nozzle (item 4) with a wrench (7 mm) from the
support plate.
The installation of the new nozzle insert assembly and of the remaining parts in
reverse order.
Note
All sliding and moveable parts must be lubricated with a non-acidic, non-resinoge-
nic grease prior to installation.

Cleaning

Warning
Do not use any hard, sharp or pointed objects when cleaning the spray gun.
Never immerse the spray gun in solvent or any other cleaning solution. The func-
tional reliability and efficiency of the gun can otherwise not be guaranteed.
WALTHER PILOT is not responsible for any damage resulting from improper clea-
ning.
The gun does not need to be dismantled for cleaning.
1. Fill the cleaned material container with a cleaning fluid compatible with the
sprayed material.
2. Operate the spray gun.
3. Do not stop the spray gun until clear cleaning fluid emerges from the nozzle.
The entire system should then be depressurised until the gun is used again.
Clean the spray gun only with cleaning agents which have been recommended by
the manufacturer of the sprayed material and which do not contain the following
constituents:
• halogenated hydrocarbons (e.g. 1,1,1-triclorethan, methylene cloride, etc.)
• acids and acidic cleaning fluids
• regenerated solvents (so-called cleaning thinners)
• paint removers
The above-mentioned constituents cause chemical reactions on electroplated
components, resulting in corrosion damage.
Clean the spray gun
• before each change of spraying material
• at least once a week or
• several times a week if required by the spraying medium and depending on the
degree of fouling.
Detailed
Cleaning
1. Disassemble the spray gun
2. Clean the air cap (Pos. 2) and the material nozzle (Pos. 4) with a soft brush
and cleaning fluid.
3. Clean all other components and the gun body with a soft cloth and cleaning
fluid.
4. Coat the following parts with a thin layer of grease:
• needle spring (Pos. 28)
• all sliding parts and bearing points.
The moving internal parts must be greased at least once a week.
The springs should always be coated with a thin layer of grease. For this, always
use a non-acidic, non-resinogenic grease and a soft brush. Assemble the gun
again in reverse order.
