Checking the Tire Pressure
Service Interval: Every 50 hours/Monthly (whichever
comes first)
Maintain the air pressure in the rear tires at 90 kPa
(13 psi). Uneven tire pressure can cause uneven cut.
To get the most accurate pressure reading, check the
tires when they are cold.
Note:
The front tires are semi-pneumatic tires and do
not require air pressure maintenance.
