LIQUID LEVEL SENSOR SYSTEM
The liquid level sensor system is an electrically controlled water level sensor which provides
water pump protection when the water level in the water tank becomes depleted. The sensor
turns off the water pump and illuminates a low water light on the control console located
inside the truck cab. The liquid level sensor circuit is controlled by an electronic module and
two relays located at the console. The liquid level sensor probe is usually located at the water
tank suction/drain assembly.
SPRAY NOZZLES
One high volume nozzle is located in the right side wall of the hopper. There are spray mist
nozzles mounted just forward of and above each gutter broom and on each side of the pick-
up head. The nozzles are located in these positions to minimize airborne dust. The switches
and indicator light for the water system are located on the operator console in the cab and
are designated:
LEFT GUTTER BROOM WATER - controls LH gutter broom nozzles
HOPPER WATER - controls hopper nozzle
RIGHT GUTTER BROOM WATER - controls RH gutter broom nozzles
YELLOW LOW WATER WARNING LIGHT - illuminates upon water depletion
DUST CONTROL WATER SYSTEM OPERATION
1. Fill water tank.
2. Start auxiliary engine, lower pick-up head and set desired RPM for sweeping.
3. Turn WATER SYSTEM switch on.
4. Turn on selector switches for desired water distribution.
WASHDOWN SYSTEM OPERATION
The optional Hi / Lo Pressure Wash Down System feature allows a hose and high pressure
wash down wand to be attached for cleaning. The water tank should be full when using the
wash down system.
HI/Lo Washdown without Hose Reel
To use the wash down system:
1. Turn the exterior water pump control switch, located on the suction side of the sweeper,
to the off position.
2. Detach the water manifold hose from the quick coupler hose connector, also located
on the suction side of the sweeper, and then attach the wash hose to the quick coupler.
3. Start the auxiliary engine, and turn on the water system.
4. With the wash-down wand in hand, turn the exterior water pump control switch to the
on position.
The wash-down system is now ready for use; simply pull the trigger and you’re ready to go.
Remember to keep safety in mind. This is not a toy.
