Safe distances (32) Minimum of 500 m (1500 ft) (33) Minimum of 15 m (50 ft)Do not go near any tire on the machine if there is evidence that the brakes have overheated. A fire in a brake is an example and burning rubber is an example. The heat can have an effect on all other tires on the machine, even though the visual indication is only at one tire.If there is an indication of a fire in a brake or the smell of burning rubber, do not go near the machine. Extinguish any fire from a remote location. Do not use a hand fire extinguisher. Stay away from the machine until the tires cool. Allow a minimum of eight hours for the tires to cool before approaching the machine.Current Recommendation for Inflation
Use dry nitrogen gas (N2 ) for all pneumatic tires. Nitrogen will not burn inside the tire.
Correct nitrogen inflation (charging) equipment and training for its use are needed to prevent too much pressure in a tire. A tire blowout or rim failure can result from equipment that is not correct or is not correctly used.
The use of nitrogen instead of air in the tires decreases the amount of tire deterioration. This is especially important for tires that have an expected long service life (four or more years). The use of nitrogen also decreases the corrosion of rim components, which decreases problems with disassembly.The pressure of a fully charged nitrogen cylinder is approximately 15000 kPa (2200 psi). This high pressure can cause a tire blowout and/or rim failure if the charging equipment is not used correctly. See Operation and Maintenance Manual, SEBU6963, "Tire Inflation with Nitrogen" for more information.Tire Inflation with Nitrogen
Servicing and changing tires and rims can be dangerous. This work must be done only by trained personnel with correct tools and procedures. If correct procedures are not followed while servicing tires and rims, the assemblies can burst with explosive force and cause serious physical injury or death. Follow carefully the specification information provided by your tire servicing person or dealer.
When the tires are inflated, clean all parts of the rim. If necessary, paint the components in order to prevent corrosion. Any sand blasting is recommended for the removal of rust. Check all components carefully and replace any of the following parts: cracked, badly worn, damaged, severely rusted and corroded. If you are in doubt, replace the parts with new parts. Never do any of the following procedures to the components of a rim: rework, weld, heat and braze .Nitrogen should be used for pressure adjustments in a tire. See your tire dealer for the correct tire pressures for job conditions and for any questions on nitrogen inflation.
Personal injury or death could result with improper tire inflation techniques.Use a self-attaching inflation chuck and stand behind the tread when inflating a tire.
Set the tire inflation equipment regulator at no more than 140 kPa (20 psi) over the recommended tire pressure.
