Drive System Maintenance
Checking the Tire Air Pressure
Service Interval:
Before each use or daily
Important:
Maintain the recommended pressure in
all tires to ensure a good quality of cut and proper
machine performance. Do not underinflate the tires.
1.
Prepare the machine for maintenance; refer to
Preparing for Maintenance (page 52)
.
2.
Measure the tire air pressure.
Note:

could result in personal injury.
Maintain the proper torque on the wheel nuts.
1.
Prepare the machine for maintenance; refer to
Preparing for Maintenance (page 52)
.
2.
Torque the wheel nuts to 94 to 122 N∙m (70 to 90 ft-lb).
