The air speed and angling must always be adjusted individually for each spray job and the given weather conditions.
The switches on the TWIN spray box controls the following:
1. Power ON/OFF
9. Fan speed
10. TWIN angling
For function of other switches see relevant part in “LookAhead liquid
system”.
By turning the knob (10) the air slot and nozzle assembly can be
angled in steps zero to 4 backwards and from zero to 6 forwards,
which is corresponding to approx. 30° backwards and 40º forwards
compared to vertical position. Regarding adjustments - see section
on “Air technique”.
By turning the knob (9) air speed can be adjusted in steps from zero
to 10. The blower revolutions can be viewed in the controller display.
The max. revolutions for the fan is 3100 r.p.m., which will give full air
speed of approx. 40 m/sec (90 mph). When booms are half-folded,
reduce r.p.m. or pressure with 25% to obtain the same performance
(air speed at nozzles).
