Adjust the DustGuard Spray Nozzles
The Spray Nozzles should be approximately 10 to
20 degrees from vertical as shown in order to spray
the water evenly top to bottom in front of the side
brooms. (Note that the hopper has been raised
slightly in the adjacent photo.) The spray pattern
should wet the oor across the whole width of the
side broom. If the spray pattern is not correct:
1. Carefully rotate the Plastic Nozzle Adapter with
a 7/8” Wrench to orient the Spray Nozzle.
2. After you rotate the Plastic Nozzle Adapter,
make sure the Brass Nozzle Adapter is holding
Plastic Nozzle Adapter securely in the Nozzle
Bracket. Tighten the Brass Nozzle Adapter to
the Plastic Nozzle Adapter as necessary.
