Safety - Section 22 OM2216 Page 22-6 Warnings and Cautions This plate warns the technician to stop the engine, before loosening or disconnecting a brake line. Turn the key switch off, and open the drain valves on all three accumulators to bleed the hydraulic pressure. A decal plate is located on top of the center cross tube. The decal provides the operator or technician with the hook-up procedure for dumping a loaded, disabled truck, by using a functional truck for hydrau- lic power. Refer to the service manual for additional instructions for using this procedure. Warning and danger plates are located inside the door of the brake system cabinet behind the cab.
This plate is placed near the four jacking points on the truck. Two are placed at the front of the truck next to the right and left frame upright supports. Two are placed at the rear of the truck under the right and left suspension supports. This plate alerts technicians to read the warning labels attached to the accumulators prior to releasing internal nitrogen pressure, or disconnecting any hydraulic lines or hardware.
