Checking the Tire Pressure
Service Interval:
Every 50 hours
Check the tire pressure every 50 hours (Figure 131).
Maintain the air pressure in the tires at 35 psi . Uneven
tire pressure can cause lose of traction. If a lose of
traction occurs, tire pressure may be increased to 50 psi
to increase track tension. Check the tires when they are
cold to get the most accurate pressure reading.
