Checking the Tire Pressure
Service Interval: Every 40 hours
Maintain the air pressure in the rear tires at 103 kPa
(15 psi). Uneven tire pressure can cause uneven cut.
Check the tires when they are cold, to get the most
accurate pressure reading.
Note:
The front tires are semi-pneumatic tires and
does not require air pressure maintenance.
