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.
Check the tires when they are cold to get the most
accurate pressure reading.
Note:
The front tires are semi-pneumatic tires and do
not require air pressure maintenance.
