OPERATION

1. Commission spray device (see spray device operating
manual).
2. Set material pressure on the pump to approx. 3 MPa
(30 bar).
3. Release trigger guard. Pull trigger guard and adjust the
pressure on the pump, until the desired spray pattern is
obtained.
4. Open the compressed air supply and adjust the
pressure to give an optimal spray pattern. The shaping
air can be adjusted for the desired spray jet width with
the air controller.
IMPORTANT: Do not use pliers to turn the shaping air
controller. Over-tightening can cause damage to the
spray gun.

Adjusting the spray pattern (fig. 6)

The spray pattern can be adjusted to suit the object being
sprayed using the fan air regulator. The illustration below
shows the influence of the shaping air regulator on the
spraying pattern.
Other nozzle sizes can be used to obtain larger or smaller
spraying patterns.
