OPERATION
IMPORTANT:
Before stopping engine, run at low idle for approximately fi ve minutes to cool hot engine parts (and allow
turbocharger to slow down while engine oil pressure is available).
1. Lower header.
2. Place ground speed lever (GSL ) (B) into N-DETENT.
3. Lock steering wheel.
4. Turn ignition key (A) counterclockwise to the OFF

Engine Temperature
The engine temperature gauge (A) is displayed in the lower
left corner of the Harvest Performance Tracker (HPT)
display.
Normal engine operating temperature is indicated when the
needle is in the green range of the gauge.
If the engine temperature exceeds 105°C (221°F), the
needle will move to the red range of the gauge. Depending
on the temperature, the engine will trigger a fault code and
an amber caution or red stop light will illuminate on the
HPT display.
When the engine temperature is below 5°C (40°F), the
engine will cycle through a period where it appears to labor
until the engine warms up. Do
NOT operate engine above
1500 rpm until the HPT engine temperature gauge is above
the blue range.

Temperature Gauge
Engine Oil Pressure
The nominal engine oil pressure is 69 kPa (10 psi) at low idle and 380 kPa (55.1 psi) at maximum rated speed.
If the oil pressure drops below the preset level of 52 kPa (7.5 psi), the Harvest Performance Tracker (HPT) displays
an engine telltale fault code to identify the issue.
If the red STOP ENGINE light illuminates, stop the engine IMMEDIATELY and investigate.
If the amber CAUTION light illuminates, stopping immediately is optional. You may continue operations and
investigate later, but you are
STRONGLY advised to monitor the situation carefully.
