WARNING BANK (See Figure 15)
The Warning Bank is located on the instrument panel and provides the operator with seven fault/status indicators
for engine and sweeper systems. The operator should monitor the indicators while sweeping. It is very impor-
tant that the operator be familiar with the meaning of each indicator.
ENGINE TEMPERATURE LIGHT
The engine temperature light illuminates to indicate an engine cooling system fault. When this
occurs the operator must turn off the sweeper immediately and have the cooling system serviced
by a qualified service technician.
ENGINE OIL PRESSURE LIGHT
When the oil pressure drops below approximately 5 PSI an automatic protection circuit shuts down
the engine and illuminates the light to indicate low engine oil pressure. When this occurs, have the
machine serviced by a qualified service technician.
CLOGGED FILTER LIGHT (Option)
The clogged filter light illuminates to indicate that the dust control filter is clogged. When this
occurs, stop the machine and use the filter shaker to clear the dirt and debris from the filter. After
using the filter shaker, continue sweeping.
HOPPER TEMPERATURE LIGHT (Option)
When the temperature of the air moving through the hopper dust control system exceeds 140° F,
an automatic protection feature shuts down the dust control fan and illuminates the hopper tem-
perature light. When this occurs, shut down the machine and carefully investigate for a possible fire
in the hopper, then manually reset the switch.
SOLUTION LOW LIGHT
The solution low warning light will illuminate when the solution tank is empty, indicating the end of
the scrubbing cycle.
RECOVERY HIGH LIGHT
The recovery high warning light will illuminate approximately 5 minutes before the recovery tank is
full, giving ample time to complete the scrubbing cycle, before the mechanical float shuts off the
vacuum to the recovery tank.
