Operating Instructions
Note:
The position numbers refer to the figure 1, see chapter 6.2 Structure of the
METACAP Spray Gun D/A, page 6-11.
—
Mix, condition and filter the coating material to be sprayed according to
the instructions of the manufacturer.
—
Fill the material container with the coating material taking into account
the maximum filling height indicated by the manufacturer.
The maximum filling height for the bottom cups is approx. 10 mm below
the cup shoulder.

Default Settings
1. Turn the knurled screw (1/38) carefully clockwise to the limit stop to
close the paint supply. Please be careful, if you use too much force, you
may damage the AKKORD needle (1/12) and the nozzle (1/4).
2. Tighten the nozzle cap (1/2) by means of the nozzle cap adjusting ring
(1/1) and then loosen the connection by a half up to a full turn.
The horns of the nozzle cap should be in a horizontal position.
3. Set the compressed air and material hose pipes under pressure. Closely
watch all pipes and connections and pay attention to potential leaks.
Attention!
When using cup sets, it is not required to set the material supply under
pressure. This will be effected automatically by starting the spraying process
by means of the spraying pressure let off by the spray gun. When the spray
process is finished, the cup will de-aerate automatically via the air supply
hose pipes.
The material pressure streams out of spray gun and is also de-aerated here,
so hold the spray gun in a vertical and steady position. In cases where this
is not possible, hold the trigger handle (1/33) at action point to ensure a
continuous initial air input.
The air supply pipes are under pressure and a material return flow into the
spray gun is therefore not possible.
Do not put down, knock over or shake spray guns with filled cups, otherwise
coating materials or solvents may be transported into the spray gun via the
air supply hose pipes.
4. Now, carry out a trial spray operation. Take a piece of cardboard, of
sheet metal or the like.
—
Keep the spray gun in a vertical position with a distance of approx. 20
cm to the work piece surface and pull the trigger handle (1/33) until
the limit stop. In this state, there should not be any visible coating
material since the AKKORD needle is still not able to lift off the
nozzle due to the tightened knurled screw (1/38). Now, turn the
knurled screw counterclockwise in a careful and gradual manner and
thus open the material supply.
