3 - CONTROLS AND INSTRUMENTS
4. Charge pressure warning
The charge pressure warning lamp will illuminate, and an audible warning will sound if there is no or
low oil pressure in the transmission. Do not operate the machine if this warning occurs. Stop the
machine immediately. The lamp will also illuminate if the engine is stopped and the key is on.
5. Hydrostatic drive temperature
The hydrostatic drive oil lamp will illuminate, and an audible warning will sound if the transmission
operating temperature is too high. Monitor the transmission operating temperature with the
hydrostatic drive temperature gauge. The transmission operating temperature is normal when the
gauge needle is in the green area of the gauge.
6. Caution master indicator
This caution master indicator illuminates yellow to indicate there is a non-critical warning. Change
the machine operating method. If the caution master indicator continues to illuminate, a scheduled
shutdown for maintenance may be required. Contact your authorized dealer if the condition persists.
7. Stop master indicator
Bring the machine safely to a stop, and turn the machine OFF immediately if the stop master
indicator lamp illuminates. This is a critical warning indicator. The multi-function display screen will
indicate the critical warning message.
NOTICE: Failure to do so may result in damage to the machine.
8. Oil pressure indicator
The low engine oil pressure warning lamp illuminates red and an audible warning will occur if there is
no or low oil pressure in the engine when the machine is operating. Bring the machine safely to a
stop and turn the machine OFF immediately. Do not run the engine if the warning lamp illuminates
while operating.
9. Park brake indicator
The parking brake lamp illuminates red when the parking brake is ON. Turn the parking brake ON or
OFF with the parking brake switch.
10. Voltage
The voltage lamp will illuminate when the battery has low voltage. The lamp illuminates with the key
switch in the ON position momentarily, and then goes out after a few seconds. If the lamp stays
illuminated, check the voltage gauge.
11. Hydraulic filter
The hydraulic filter lamp illuminates if there is a problem with the hydraulic filter. If the hydraulic filter
lamp illuminates during normal operation with the hydraulic oil at operating temperature and the
engine at full throttle, stop the engine and replace the hydraulic filter.
