OPERATION
4.3.2 Break-In Period
The windrower is ready for normal operation. However there are several items to check and watch out for during
the first 150 hours.
In addition to the following, perform the items specified in Break-In Inspections, page 383 .
DANGER
Before investigating an unusual sound or attempting to correct a problem, place ground speed lever (GSL)
in N-DETENT, shut off engine, and remove key.
IMPORTANT:
Until you become familiar with the sound and feel of your new windrower, be extra alert and
attentive.
• Operate engine at moderate load and avoid extremely heavy or light loading for longer than 5 minutes.
• Avoid unnecessary idling. If engine will be idling longer than 5 minutes after reaching operating temperature, turn
key OFF to stop engine.
• Check engine oil level frequently. Watch for any signs of leakage. If oil must be added, refer to Checking Engine
Oil Level, page 293 .
NOTE: During the break-in period, a higher than usual oil consumption should be considered normal.
NOTE: If windrower must be driven in cold weather (below freezing), let engine idle for 3 minutes, and then
operate at moderate speed until oil has warmed up.
• Watch coolant gauge in cab for temperature rising beyond normal operating range. Check that coolant level at
reserve tank (mounted next to radiator) stays between HOT and COLD marks on tank.
Refer to
Engine Cooling System, page 310 . If over-heating problems occur, check for coolant leaks.
