Tire Information
Explosions of air inflated tires have resulted from heat-induced gas combustion inside the tires. The heat, generated by welding or heating rim components, external fire, or excessive use of brakes can cause gaseous combustion.A tire explosion is much more violent than a blowout. The explosion can propel the tire, rim and axle components as far as 500 m (1500 ft) or more from the machine. Both the force of the explosion and the flying debris can cause personal injury or death, and property damage. Do not approach a warm tire closer than the outside of the area represented by the shaded area in the illustration.Dry nitrogen (N2) gas is recommended for inflation of tires. If the tires were originally inflated with air, nitrogen is still preferred for adjusting the pressure. Nitrogen mixes properly with air.Nitrogen inflated tires reduce the potential of a tire explosion, because nitrogen does not support combustion. Also, nitrogen helps prevent oxidation and the resulting deterioration of rubber and corrosion of rim components.Proper nitrogen inflation equipment and training in its use are necessary to avoid overinflation. A tire blowout or rim failure can result from improper or misused equipment.Stand behind the tread and use a self-attaching chuck when inflating a tire.Servicing and changing tires and rims can be dangerous and should be done only by trained personnel using proper tools and procedures. If correct procedures are not followed while servicing tires and rims, the assemblies could burst with explosive force and cause serious personal injury or death. Follow carefully the specific information provided by your tire or rim servicing personnel or dealer.Mounting and Dismounting
* Mount and dismount the machine only where steps and/or handholds are provided.* Inspect, and when necessary, clean and have repairs made to steps and handholds before mounting and dismounting. * Face the machine when mounting and dismounting.* Maintain a three-point contact (two feet and one hand or one foot and two hands contact) with the steps and handholds.* Never get on or off a moving machine.* Never jump off the machine.* Do not try to climb on or off the machine when carrying tools or supplies. Use a hand line to pull equipment up onto the platform.* Do not use any controls as handholds when entering or leaving the operator's station. * When machine is equipped with roading fenders, the following instructions must be followed before climbing on the battery boxes to perform maintenance or opening the engine access doors. 1. Move the lever (1) to unlock the roading fender (2). 2. Open roading fender (2) completely before climbing on machine.3. Mount the battery box using a three-point contact (two feet and one hand or one foot and two hands contact) with the steps and handholds. 4. After climbing off the battery box, close and lock the roading fender in the operating position.Alternate Exit
Machines equipped with cabs are equipped with alternate exits. For additional alternate exit information, refer to topic Alternate Exit in the Monitoring Systems and Cab Features
