Changing The Spray Pattern; Converting / Repairing The Spray Gun; Replacing The Material Nozzle And Air Cap; Replacing The Material Needle (Component A) - WALTHER PILOT PILOT 2K Betriebsanleitung

Note
The gun must be flushed with a suitable solvent before initial commissioning to pre-
vent contamination of the spraying material.
4.1 Spray Pattern Test
A spray pattern test should always be generated when:
• the spray gun is used for the first time
• the spray material has been replaced
• the gun has been disassembled for maintenance or repair
The spray pattern can be applied to a sample work piece, sheet metal, cardboard or
paper.
1. Start operation of the spray gun to generate a spray pattern test (see 4
Connecting supply lines and
Operation
2. Check the spraying pattern trial and change the settings on the spray gun, as
necessary (see 4.2 Changing the spray pattern).
4.2

Changing the spray pattern

You can change the spray pattern on the PILOT BOND 2 K by making the following
settings:
Adjusting the material flow volume
The material volume can be regulated by turning the adjusting
screw (item 10) in or out. The material volume is increased by
turning it to the left (unscrewing) and reduced by turning it to the
right (screwing down).
Regulating the material pressure
You can adjust the material pressure only on the pump or the
pressure tank. Please follow the directions and safety instruc-
tions of the manufacturer.

Converting / repairing the spray gun

The air cap / material nozzle / needle combination matching the spraying material
represents an interactively tuned unit - the nozzle set. Always replace the entire
nozzle insert to maintain the desired spray pattern quality.
Note
All movable and sliding parts must be greased with WALTHER PILOT gun grease
before installation in the gun body (Art. No.: V 00 000 00 001).
