Mounting/demounting and inflation is dangerous and number of operators are killed or injured every year.
So every step must be taken with caution.

* Only specially trained persons should mount tires. Follow the RMA wall chart.
* ALWAYS match rim diameter with tire diameter.
* NEVER mount tire on a cracked, bent, rusted or otherwise damaged rim or a rim which has been repaired.
* NEVER put a flammable substance into a tire.
* ALWAYS clean and lubricate rim and tire beads.
* ALWAYS use an extension air hose with gauge and clip-on air chuck.
* ALWAYS lock wheel on tire mounting machine or place in safety cage when inflating.
* ALWAYS stand clear, and NEVER lean or reach over the tire/rim assembly when inflating.
* NEVER inflate over 40psi (275 kPa) to seat beads.
* ALWAYS adjust tire pressure to vehicle manufacturer's recommendations after beads are fully seated.
