*GENERAL OPERATION*
Grill Brush Operation
Brush rotation starts and stops with a signal from the Customer supplied Controller
system to the Customer's hydraulic power pack which drives the hydraulic motors on
the brushes. This Controller Start-Stop signal should also control soap solution
delivery to the spray bar on each brush.
BE CERTAIN THAT THE BRUSHES ROTATE AGAINST VEHICLE TRAVEL
With the brushes rotating (against the direction of vehicle travel and at proper RPM)
the vehicle front grill contacts the washers at the center of the grill and travels across
the grill of the vehicle maintaining steady contact while cleaning the front of the
vehicle.
After passing beyond the front of the vehicle the brush will travel down the side of the
vehicle continuing to clean the vehicle as a side brush.
Proper cloth penetration on flat vehicle surfaces should be 3 to 4 inches. As the
wraparounds gear around corners, such as fenders, cloth penetration may be greater,
but not deeper than half the distance to the aluminum brush core.
Optional Retract Operation
When selected by the Operator's remote Programmer push button station the
wraparound brushes will retract from the center of the wash tunnel toward the tunnel
outer walls. This can be done individually if one solenoid is used for each arm.
This is accomplished, when the push button is pressed, by completing an electrical
circuit through the equipment Programmer to pass single phase power at the preset
pulse count of the Programmer to the retract air solenoid valve. The air solenoid valve
now opens and allows compressed air to pass through to the rod end port of each air
cylinder causing the brush hangers to retract.
