Safety - Section 20 08/11 OM2036 Page 20-10 PRECAUTIONS FOR MAINTENANCE Securing The Dump Body BEFORE PERFORMING MAINTENANCE Stopping The Engine Before Service Before performing inspections or maintenance, stop the machine on firm, flat ground. Lower the dump body, shut the engine off, and apply the parking brake. Install wheel chocks. To avoid serious personal injury or death, the body retention cable must be installed whenever personnel are required to perform maintenance on the truck while the dump body is in the raised position. If the engine must be operated during service, move the selector switch to the NEUTRAL position, and apply the parking brake. Perform this work with two people.
One person must sit in the operator's seat to stop the engine, if necessary. DO NOT move any controls during these situations unless necessary for service. The Komatsu body-up safety cable can only be used with a Komatsu body. Non-OEM body may not accommodate the Komatsu body-up safety cable. The end user must ensure that a proper cable is used. When servicing the machine, DO NOT touch any moving parts. DO NOT wear loose clothing. When servicing the truck with the dump body raised, place the dump lever in the HOLD position. Install the body-up retention cable securely. Warning Tag DO NOT start the engine or operate the controls while a person is performing maintenance on the truck.
Serious injury or death may result. FIGURE 2-1. Body-Up Cable 1. Rear Body Ear 2. Cable Stored Position 3. Cable 4.
