6.3.2 ALARM SCREENS _________________________________________________________
There are six alarm screen displays to tell the operator or technician of a problem that must be corrected.
When the engine oil pressure is less than 7 psi (0.48 BAR), the Low Oil Pressure screen is
shown on the LDU. The horn will activate, the reels will stop and lift to full up position and the
engine oil-pressure light illuminates. Immediately stop the engine. Inspect the oil level in the
engine.
When the hydraulic oil filters need to be replaced, the Hydraulic Oil Filter screen is shown on
the LDU. The reels will stop and lift to full up position. Return the mower to the service area and
replace the filters.
When the coolant temperature is greater than 230° F (110° C), the High Engine Temperature
screen is shown on the LDU. The horn will activate, the reels will stop and lift to full up position
and the coolant-temperature light illuminates. Immediately stop the engine. Remove leaves
and grass clippings that can decrease the air flow through the rear screen and the radiator.
When the system voltage is less than 12 Volts DC, the Low Battery Voltage screen is shown
on the LDU. If the screen does not turn off when the engine starts or the battery light is
illuminated, check the alternator and the battery.
When the hydraulic fluid level in tank is low, the Low Hydraulic Fluid Level screen is shown
on the LDU. The horn will activate, the reels will stop and lift to full up position and the hydraulic
fluid level light illuminates. Visually inspect the mower for indications of leaks around
connections, hoses and hydraulic components.
When the traction pedal is pressed in the forward or reverse direction with the parking brake
switch engaged, the Pedal and Brake On screen is shown on the LDU. The horn will activate.
Return the traction pedal to the Neutral position and disengage the parking brake switch before
you drive the mower.
