Warnings & Cautions - Section 22 OM2204 Page 22-6 Warning and Danger plates are located inside the door of the brake system cabinet behind the cab. This DANGER plate alerts technicians to read the warning labels attached to the side of each of the accumulators prior to releasing internal nitrogen pressure or disconnecting any hydraulic lines or hardware. This WARNING plate alerts the technician to stop the engine, turn off the key switch, and open the drain valves on all three accumulators to bleed the hydrau- lic system pressure before disconnecting a brake line.
This WARNING plate, attached to the automatic lube system grease reservoir warns the technician not to remove the reservoir cover. The grease reservoir should be filled through the grease filter to prevent contamination of the grease supply. This Danger plate is attached to all four suspensions and the steering accumulator. The plate contains instructions for releasing internal pressure before disconnecting any hydraulic lines or hardware. Serious injury can occur if these directions are not followed.
