Adjust the tire pressure as needed.
IMPORTANT:
Check the maximum inflation rating on the tire
’
s sidewall. Do
NOT
inflate the tire beyond the maximum pressure
specification.
Tightening Drive Wheel Nuts
The wheel nuts must be tightened in a specific pattern to prevent damage to the drive wheels.
Whenever a wheel is installed, retorque the drive wheel nuts after one hour of operation. Retorque the installed wheel
every hour until two consecutive checks demonstrate that the wheel nut torque is unchanged.
IMPORTANT:
•
To avoid damage to the wheel rims and studs, tighten the wheel nuts by hand. Do
NOT
use an impact wrench. Do
NOT
apply lubricant or anti-seize compound to the threads of the wheel studs. Do
NOT
overtighten the wheel nuts.
•
Ensure that only the manufacturer-specified wheel nuts are used to secure the drive wheel.

Nut Tightening Sequence
1.
Tighten drive wheel nuts (A). Ensure that the nuts and studs
are dry. Do
NOT
apply lubricant or anti-seize compound to
the threads of the wheel studs. Torque each nut to 510 Nm
(375 lbf·ft) using the tightening sequence shown at right.
2.
Repeat the tightening sequence twice more.
3.
Retorque the installed wheel every hour until two
consecutive checks demonstrate that the wheel nut torque
is unchanged.
Checking Wheel Drive Lubricant Level
Check the wheel drive lubricant level according to the interval specified in the maintenance schedule. Ensure that the
wheel drive lubricant level is correct to maximize the service life of the components.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator
’
s seat for any reason.
CAUTION
Park on a level surface with the ground speed lever (GSL) in the N-DETENT position and the steering wheel in the
locked (centered) position. Wait for the cab display module (CDM) to beep and display an
“
In Park
”
message to confirm
that the parking brake is engaged.
1.
Park the windrower on level ground.
