Check inflation pressure of tires
WARNING
When inflating a tire, check that no one will enter the working
area. Use an air chuck which has a clip and which can be fixed
to the air valve.
While inflating the tire, check the inflation pressure occasionally
so that it will not rise too high.
If the rim is not fitted normally, it may be broken and scattered
while the tire is inflated. To ensure safety, place a guard around
the tire and do not work in front of the rim but work on the tread
side of the tire.
Abnormal drop of inflation pressure and abnormal fitting of the
rim indicate trouble in the tire or rim. In this case, be sure to ask
a tire repair shop to carry out repairs.
Be sure to observe the specified inflation pressure.
Do not adjust the inflation pressure of the tires just after high-
speed travel or heavy-duty work.
Check
Measure the inflation pressure with a tire pressure gauge while
the tires are cool before starting work.
Inflation of tires
Adjust the inflation pressure properly.
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.
The proper inflation pressure is shown below.
NOTE
The optimum inflation pressure differs according to the type of
work. For details, see "Handling the tires (3-157)".
