    Tire InformationSMCS Code: 7000

    Explosions of air inflated tires have resulted fromheat-induced gas combustion inside the tires.Explosions can be caused by heat that is generatedby welding, by heating rim components, by externalfire, or by excessive use of brakes.

    A tire explosion is much more violent than ablowout. The explosion can propel the tire, the rimcomponents, and the axle components as far as500 m (1500 ft) or more from the machine. Both theforce of the explosion and the flying debris can causeproperty damage, personal injury, or death.

    g00337832Illustration 20

    (A) At least 15 m (50 ft)(B) At least 500 m (1500 ft)

    Do not approach a warm tire. Maintain a minimumdistance, as shown. Stay outside the shaded area inIllustration 20.

    Do not use water or calcium as a ballast for the tires.Dry nitrogen gas is recommended for inflation of tires.If the tires were originally inflated with air, nitrogenis still preferred for adjusting the pressure. Nitrogenmixes properly with air.

    Nitrogen inflated tires reduce the potential ofa tire explosion because nitrogen does not aidcombustion. Nitrogen helps to prevent oxidation ofthe rubber, deterioration of rubber, and corrosion ofrim components.

    To avoid overinflation, proper nitrogen inflationequipment and training in the usage of the equipmentare necessary. A tire blowout or a rim failure canresult from improper equipment or from misusedequipment.

    When you inflate a tire, stand behind the tread anduse a self-attaching chuck.

    Servicing tires and rims can be dangerous. Onlytrained personnel that use proper tools and properprocedures should perform this maintenance. Ifcorrect procedures are not used for servicing tiresand rims, the assemblies could burst with explosiveforce. This explosive force can cause seriouspersonal injury or death. Carefully obey the specificinstructions from your tire dealer.

    Guards

    Rollover Protective Structure(ROPS), Falling Object ProtectiveStructure (FOPS) or Tip OverProtection Structure (TOPS)The ROPS/FOPS Structure (if equipped) on yourmachine is specifically designed, tested andcertified for that machine. Any alteration or anymodification to the ROPS/FOPS Structure couldweaken the structure. This places the operatorinto an unprotected environment. Modifications orattachments that cause the machine to exceed theweight that is stamped on the certification plate alsoplace the operator into an unprotected environment.Excessive weight may inhibit the brake performance,the steering performance and the ROPS. Theprotection that is offered by the ROPS/FOPSStructure will be impaired if the ROPS/FOPSStructure has structural damage. Damage to thestructure can be caused by an overturn, a fallingobject, a collision, etc.

    Do not mount items (fire extinguishers, first aidkits, work lights, etc) by welding brackets to theROPS/FOPS Structure or by drilling holes in theROPS/FOPS Structure. Welding brackets or drillingholes in the ROPS/FOPS Structures can weakenthe structures. Consult your Caterpillar dealer formounting guidelines.

    The Tip Over Protection Structure (TOPS) isanother type of guard that is used on mini hydraulicexcavators. This structure protects the operator inthe event of a tipover. The same guidelines for theinspection, the maintenance and the modification ofthe ROPS/FOPS Structure are required for the TipOver Protection Structure.

    Other Guards (If Equipped)Protection from flying objects and/or falling objects isrequired for special applications. Logging applicationsand demolition applications are two examples thatrequire special protection.

    A front guard needs to be installed when a work toolthat creates flying objects is used. Mesh front guardsthat are approved by Caterpillar or polycarbonatefront guards that are approved by Caterpillar areavailable for machines with a cab or an open canopy.On machines that are equipped with cabs, thewindows should also be closed. Safety glasses arerecommended when flying hazards exist for machineswith cabs and machines with open canopies.

    If the work material extends above the cab, topguards and front guards should be used. Typicalexamples of this type of application are listed below:

    Demolition applications

    Rock quarries

    Forestry products

    Additional guards may be required for specificapplications or work tools. The Operation andMaintenance Manual for your machine or yourwork tool will provide specific requirements for theguards. Consult your Caterpillar dealer for additionalinformation.
