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.
