METHOD FOR CHECKING AND INFLATING TIRE
WARNING
• When inflating the tire, check that no one can enter the area around the tire, and always use an air
chuck with a clip that can be fixed to the air valve.
• To prevent the tire inflation pressure from becoming too high, measure the pressure from time to
time with an air gauge while pumping up the tire.
• When it is inflated, the rim parts may fly out, if they are not fitted properly.
Put a fence around the tire for protection. The worker must not stand in front of the rim but must
stand on the tread side during work.
• Abnormal drop of inflation pressure and abnormal fitting of the rim indicate a trouble in the tire or
rim. In this case, be sure to ask a tire repair shop for repair.
• Be sure to observe the specified inflation pressure.
• Do not adjust the tire inflation pressure immediately after traveling at high speed or operating under
heavy load.
Check the tire inflation pressure before starting work while the tires are cold.
When inflating a tire, use an air chuck which can be fixed to the
air valve of the tire as shown in the figure.
Do not work in front of the rim but work on the tread side of the
tire.
