OM2025.2 Safety - Section 2 Warnings and Cautions Page 2-23 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 en- gine 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 both 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. These DANGER plates are mounted on the outside of each frame rail to alert technicians to read the warning labels attached to the side of each of the accumulators (see below) prior to releasing internal nitrogen pres- sure or disconnecting any hydraulic lines or hardware. There are similar decals mounted on top of each of the accumulators (both steering and brake) with the same DANGER message.
These WARNING decals are mounted on the side of each of the accumulators (both steering and brake) to alert technicians to discharge all gas and hydraulic pressure, and to read the maintenance/service manual prior to performing any service.
