SERVICE PROCEDURE
CHECK OF INFLATION PRESSURE OF TIRES AND INFLATION OF THEM
WARNING
When inflating a tire, check that any person will not enter the working
area and 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. Accordingly, 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 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 inflation pressure of the tires just after high-speed
travel or heavy-load 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.

, 81.7 PSI}
18.00R33
aa
(if equipped)
0.69MPa {7.00kg/cm

NOTICE
If the tires are used when the inflation pressure is less than the value given in the table above, the rim may be damaged.
Always keep the tire inflation pressure within +0 to +0.03 MPa {0.3 kg/cm
2
, 4.3 PSI} of the value in the table above.
