Break-off point adjustment
Tools:
Safety glasses and gloves; magnifying glass (eyepiece); 2.5 mm screwdriver
Preparation:
□ Place the head on its maintenance stand.
□ Turn on the jet(s) for at least 30 minutes.
□ Remove the head cover.
Note: each jet on a multijet head has its own potentiometer (right jet - right
potentiometer, etc.).
Adjustment:
To adjust the break-off point, look at the jet opposite the charge electrode (stroboscopic
LED) through the eyepiece (see Figure 2)
□ Start by turning the potentiometer to the left until it stops. The jet is not modulated.
□ Slowly turn to the right until the jet break-off point is in the center of the charge
electrode. The shape should be similar to the one illustrated in Figure 2 (Correct
adjustment).
□ Figure 1 shows how a properly adjusted break-off point should appear. Look only at
the shape of the drops just under the break-off point.
