Replacing air cap and material nozzle
1.
Unscrew the fluted retaining ring (Pos. 1) from the front body section (Pos. 7).
2.
Pull the air cap (item 2) from the front body section.
3.
Unscrew the material nozzle (Pos. 3) from the front section.
4.
Screw in the desired material nozzle (if necessary replace the sealing washer)
and mount the desired air cap to the front body section.
5.
Screw the retaining ring on the front body.
Changing the material needle
1.
Unscrew the drawbar (Pos. 27).
2.
Unscrew the cap (Pos. 26) from the piston casing (Pos. 19).
3.
Screw the drawbar into the material needle (Pos. 21) and pull the material need-
le out of the piston casing.
Assembly takes place in reverse order.

Conversion of adapter plate from radial to circulation method
1.
Loosen the two cylinder head screws (Pos. 38) and take the spray gun off the
adapter plate.
2.
Remove the sealing pin (Pos. 37) with O-ring (Pos. 36) from the gun. (See 4.1
radial or circulation method)
3.
Screw the plug (Pos. 10) into the front section.
4.
Insert the second material connection (V 00 101 01 003 for adapter plate alumi-
nium nickel coated at rear or V 21 900 20 003 for adapter plate stainless steel
lateral material connection) into the plate.

Cleaning
6.1
Safety Warnings
•
Prior to any servicing and repair work: Make sure that the spray gun is in unpres-
surized condition, i.e. all air and material inputs must be shut off - if not, immi-
nent risk of injury.
•
No open fires, naked light and smoking allowed in the work area. When spraying
readily flammable media such as cleaning solutions, there is an increased risk
of fire and explosion.
•
Observe the safety warnings issued by the manufacturer. Aggressive and corro-
sive media represents risks and hazards to personal health.
6.2
Cleaning - Complete
The spray gun must be regularly cleaned and lubricated with WALTHER PILOT
spray gun grease (V 00 000 00 001) in order to enhance its service life and ensure
the functionality of the spray gun.
Clean the gun only with cleaning solutions recommended by the manufacturer of the
spraying material used at the time. It is important to make sure that cleaning soluti-
44
ons 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 the electroplated components
resulting in corrosion damage.
WALTHER Spritz- und Lackiersysteme is not responsible for any damages resulting
from such treatment.
Clean the spray gun
•
prior to each change of the spraying medium.
•
at least once a week.
•
as often as may be required by the spraying medium handled and the resultant
degree of fouling.
Caution
Never immerse the spray gun in solvent or any other cleaning solution. The functio-
nal reliability and efficiency of the gun can otherwise not be guaranteed.
Caution
Do not use any hard, pointed or sharp-edged objects when cleaning the spray gun.
Any damage of the precision-made parts are likely to affect your spraying results.
1.
Dismantle the spray gun in accordance with 5.5 Retooling the Spray Gun.
2.
Use a soft brush together with a compatible cleaning sulotion to clean the air cap
and nozzle.
3.
Clean the remaining parts and the spray gun body with a suitable cloth and
cleaning solution.
4.
Apply a thin film of the appropriate grease to the:
•
sealing collar of the piston
•
O-ring of the piston
•
material control needle
•
needle spring
Use WALTHER PILOT gun grease and a brush for this purpose.
The spray gun is then reassembled in reverse order.
