OM2026.2 Safety - Section 2 Warnings and Cautions Page 2-21 A warning plate is mounted on top of the radiator surge tank cover near the radiator cap. The engine cooling system is pressurized. Always turn the key switch off and allow the engine to cool before removing radiator cap. Unless the pressure is first released, removing the radiator cap after the engine has been running for a time will result in the hot coolant being expelled from the radiator. Serious scalding and burning can result. Warning plates are mounted on the frame in front of, and to the rear, of the front tires. All personnel are warned that the clearances change when the truck is steered and could cause serious injury.
Warning plates are attached to both the hydraulic tank and fuel tank to alert technicians not to work on the truck with the body in the raised position unless body-up retention device (pins or cable) is in position. This Danger plate is attached to each suspension and steering accumula- tor(s). The plate contains instructions for releasing internal pressure before disconnecting any hydraulic lines or hardware.
