• Do not stand over tire. Use a clip-on

chuck and extension hose.

• Never increase air pressure beyond

pressure specified on tire side wall to seat the bead on the rim.

• Replace the tire if it has a defect.

• Replace a wheel rim that has cracks, wear

or severe rust.

• Never weld a wheel rim.

• Never use force on an inflated or partially

inflated tire.

• Make sure the tire is correctly seated

before inflating to operating pressure.

• If the tire is not in correct position on the

rim, or is too full of air, the tire bead can loosen on one side, causing air to leak at high speed and with great force. An air leak of this nature can thrust the tire in any direction, endangering anyone in the area.

• Make sure all the air is removed from a

tire before removing the tire from a rim.

• Do not remove, install or make repairs to

a tire on a rim unless you have the proper equipment and experience to perform the job.

• Take the tire and rim to a qualified tire

repair shop.
