DUST CONTROL SYSTEM
The dust control system is designed to control the dust created by the operation of the sweeper
under normal sweeping conditions. The dust control system (often referred to as the water sys-
tem) is only effective when the sweeper is operating properly. Problems such as damaged or
worn door seals, worn pick-up head curtains, holes in the suction/pressure hoses can cause
extremely dusty conditions that cannot be controlled by a properly functioning dust control
system.
A. OPERATION
The following procedure is recommended for operation of the TYMCO Model 600 dust
control system:
1. Fill water tank. A 220 gallon water tank is standard and is located just below the
auxiliary engine. The filler port is located on the top front of the tank. The 2-1/2" fire
hose provided with the sweeper attaches to the filler port and is stored in a bin
provided on the right side of the sweeper. In the end of the fire hose which attaches
to the hydrant is a cone shaped strainer.
Always purge the fire hydrant before attaching the fire hose to fill the tank. The tank
is full when water is observed to spill from around the suction manifold on top of the
tank. The TYMCO tank filling system is an anti-siphon system as water is put into
the tank from the filler neck on top of the tank. At end of shift, open drain valve to
flush tank.
2. Controls for the dust control system are located in the cab on the control console
panel. To activate system, start sweeper engine, then turn on main water toggle
switch which activates the water pump. If the tank contains water, select the desired
water distribution switches and water will continue to spray until sweeper engine is
shut off, water toggle switch is turned off or water tank is emptied. If water tank is
emptied, low water light will come on, indicating that the water system has shut off
automatically.
B. SERVICE
There are essentially four service areas for the water system:
1. Water Tank
2. Pre-Filter
3. Water Pump
4. Spray Nozzles
Service these areas routinely according to the following directions:
1. Water Tank - The water tank should be flushed at the end of each shift to remove
contaminants. Fill tank and then allow to drain.
2. Pre-Filter - A pre-filter is located between tank and water pump to remove any
contaminants before they reach the pump. The pre-filter has a removable cleanout
bowl which should be removed and cleaned once a day.
