SAFETY SUPPORT MAINTENANCE PROPERLY Explosive separation of a tire and rim parts can cause serious injury or death. Do not attempt to mount a tire unless you have the proper equipment and experience to perform the job. Have it done by your authorized dealer or a qualified repair service. Always maintain the correct tire pressure. DO NOT inflate tire above the recommended pres- sure. When inflating tires, use a chip-on chuck and ex- tension hose long enough to allow you to stand to one side and not in front of or over the tire as- sembly. Use a safety cage it available. Inspect tires and wheels daily. Do not operate with low pressure, cuts bubbles, damaged rims, or missing lug bolts and nuts.

Never cut or weld on an inflated tire or rim as- sembly. Heat from welding could cause an in- crease in pressure and may result in tire explo- sion.
