Checking the Tire Pressure
Service Interval:
Every 50 hours/Monthly (whichever
comes first)
Maintain the air pressure in the rear tires at 12-14 psi
(83-97 kPa). Uneven tire pressure can cause an uneven
cut.
Note:
The front tires are semi-pneumatic tires and do
not require air pressure maintenance.
