WARNING
If tire has been run flat, or is over- or underinflated
when tire pressure is measured and operating terrain is
compared to Table 3-4, or if wheel/tire assembly has
obvious or suspected damage, it is not safe to adjust tire
pressure. Completely deflate tire according to para 3-9,
and remove the tire from the axle. Failure to follow
these procedures may result in serious personal injury
or death.
