OM2017.2 Safety - Section 2 Warnings and Cautions Page 2-23 The dump procedure for a disabled truck is located on the left side of the torque tube near the hoist valve. This decal pro- vides the operator or technician with the proper hook-up procedure for dumping a loaded disabled truck. A WARNING plate is attached to the hydraulic tank to alert technicians that hydraulic oil becomes heated during operation and care must be taken to avoid burns when it is necessary to open the hydraulic system. There is always a chance of residual pressure being present. Open fittings slowly to allow any pressure to bleed off before removing any connections.
Any operating fluid, such as hydraulic oil or brake fluid escaping under pressure, can have sufficient force to enter a person’s body by penetrating the skin. Serious injury and possibly death may result if proper medical treatment by a physician familiar with this injury is not received immediately. Warning plates are attached to both the hydraulic and fuel tank to alert technicians not to work on the truck with the body in the raised position unless body-up safety devices are in position. DUMP PROCEDURE FOR DISABLED TRUCK 1. HOOK UP QUICK DISCONNECTS: ONE LINE FROM LARGE HOIST CROSS TUBE ON DISABLED TRUCK TO SMALL HOIST CROSS TUBE ON GOOD TRUCK.
