Adjusting the Height of the Nozzle Tips
The MacDon sprayer is equipped with a sub-boom
that allows the nozzles to be in a straight line. The
sub-boom will fold up when the booms are folded
for transport which prevents dirt from plugging the
nozzle tip when the sprayer is being transported. It
can be used with different nozzle spacing for
different applications and it can be used with a wet
or dry boom.
If the tip of nozzle is below the main boom, the sub
boom can be raised to prevent damage to the
unprotected nozzle tip:
1. Lift the sub-boom by hand and support the
boom.
2. Insert a cotter pin through the hole A of the
sub-boom mounting bracket. Secure the
cotter pin by bending the ends of the cotter
pin.
3. Release the sub-boom and allow it to rest on
the cotter.
Install a cotter pin through each bracket to maintain
a consistent height for each independent sub-
boom.
The nozzle tips can be pointed forward as
recommended by some chemical manufacturers.
1. Loosen the nuts securing the tube to each sub-
boom mounting bracket.
2. Adjust the nozzle tips to the desired angle and
secure the tube by tightening the U-shaped
clamps.
