Tire Changing Equipment and Tools Tire changing procedures vary with individual operators. Certain tools, however, are essential. 1) Heavy equipment jack. 2) Tire tools and irons. These include: • Several irons with dished or spoon shaped ends. • Crowbar. • Heavy duty rubber or wood mallet or lead or babbit hammer. 3) Wheel chucks. 4) Jack stands 5) Air compressor. 25 6) Service truck. In larger operations, a fully equipped truck can minimize down time. The truck should be equipped with: • A mounted hoist. The hoist should be strong enough to handle the largest tires. • An air compressor with a regulator. Models are available which operate off the truck engine or are self powered. • Large bore/super large bore inflating equipment. This minimizes inflation time. • Clip-on chucks with remote controls. These allow inflation from a safe distance.
Before performing any service on Off-The-Road tires, read and understand all safety precautions. Do not mount or demount tires without proper training. GENERAL SAFETY INSTRUCTIONS The following section of this Manual contains important safety information, including steps necessary to avoid accidents that may result in death, serious injury or property damage. Follow all procedures and safety instructions exactly. Wear proper personal protective equipment (PPE). PRECAUTION Before removing anyy rim or wheel compponent (i.e., nuts or rim cclamps): • Exhhausstt all airr frrom a single tire. • Exhhaustt all airr frrom botth tiress of a dual assemblly. Remove valve core compleetely. This will assure all air is exhausted from tire. • Remove both cores from dual asseemmbly. •• RRunn aa piecce of wwiire tthrrouggh stem ttoo be sure it’’s not plugged. DEMOUNTING 26 REASON FOR PRECAUTION A broken rim part under pressure can blow apart and cause fatal injury. If you remove lugs while tire is under pressure, the assembly may fly apart. Foreign material may clog the valve stem during deflation. Ice may form as the air leaves the tire. This can clog the valve stem. Allways staannd clear during deflation. If the assembly bursts, the operator should be far away from the explosive force. Usse appproved eye protecction. Protect eyes from dust and dirt when exhausting air from tires.
