CHECKING TIRE PRESSURE
Mounting Screws
Figure 29. Chute Direction Control Rod Gear Adjustments
The air pressure in each tire (Figure 30) should be 20 psi (136 kPa) and should be equal for both tires for best per- formance. Be sure to keep caps on valves to prevent entry of debris into the valve stem when tires are filled.
