Console Maintenance
General Care
The Console is a completely sealed instrument designed
to withstand exposure to outdoor environments. Pressure
washing of the console face is acceptable when water
spray pressure does not exceed 2000 psi while using a
30 degree or greater nozzle tip (fan spray) at a distance
no closer than 12". Oil, gasoline, chemicals and deter-
gents spilled on the console should be wiped off immedi-
ately with a clean dry cloth.
Never use abrasive or corrosive cleaning products on the
console.
Bypassed or Failed Safety Interlock Switch
Detection
While monitoring the safety interlocks, the console iden-
tifies interlock switches that have failed, closed, or have
been bypassed closed. When the console detects a
failed or bypassed switch, it slowly flashes the correspon-
ding indicator LED and flashes "SEAT"/"BRAKE"/"DRIVE"
"INTLK" "FAULT" on the LCD.
The console allows the equipment to continue operating
normally for a short time after detecting a potentially
faulty switch to allow the equipment to return to a service
area, locking out engine operation after this time is ex-
hausted.
To clear this error, replace or repair the faulty interlock
switch and open the switch while the console is unlocked
by entering your Key Code.
Service Alerts
Service alerts remind the operator to perform specific
maintenance tasks based on equipment run time. While
the console is unlocked by entering your Key Code, click
key code button 1 (12) once to enter service alert display,
and again as needed to select the desired alert to display.
The display returns to engine hour meter after 30 sec-
onds of inactivity.
