Checking the Tire Pressure

Service Interval: Every 50 hours/Monthly (whichever
comes first)
Maintain the air pressure in the rear tires at 13 psi (90 kPa).
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.
