  • Page 52 DUST SUPRESSION SYSTEM (IF EQUIPPED) The dust suppression system keeps surface dust to a minimum by misting water along the sweeping path. Each system has 7 or 8 nozzles, a water pump, strainer, drain and tank. The tank holds approximately 100 gallons There are five nozzles located along the front bumper of the truck, two nozzles mounted near the head on each side of the unit, and one nozzle mounted near the broom, if equipped.
  • Page 53 LUBRICATION - FAN BEARINGS Do not attempt to lubricate or adjust the blower fan while the fan is turning. The fan spins at a high RPM and is dangerous. The fan bearings only require minimal lubrication to keep them spinning quiet and effective.

  • Page 54: Repairs & Troubleshooting

    O-ring. The hydraulic system on your NiteHawk Sweeper is vented so it is not uncommon to have a mist of fluid on top of your reservoir; this can sometimes be mistaken for a leak. If a leak does occur call the NiteHawk Service Line at 1-800-448-9364. MANUAL OVERRIDES All models are equipped with manual override buttons on each directional valve.
