Lower the dump body, stop the engine and apply the parking brake. Warning Tag Starting the engine or operating the controls while others are performing maintenance on the truck can lead to serious injury and/or death. If the engine must be operated during service, such as when cleaning the radiator, always move the transmission control lever to the NEUTRAL position and apply the parking brake. Always perform this work with two people.
One person must sit in the operator's seat to stop the engine, if necessary. Never move any controls, not related to the task at hand, during these situations. When servicing the machine, DO NOT touch any moving parts. Never wear loose clothing or jewelry. Always attach the warning tag to the steering wheel in the operator's cab to alert others that you are working on the machine. Attach additional warning tags around the machine, if necessary. Put wheel blocks under the wheels to prevent machine movement. Tags are available from your Komatsu distributor. When performing service with the dump body raised, always place the dump lever in the HOLD position.

Using damaged, low quality, faulty, or makeshift tools can cause personal injury. Any time personnel are required to perform main- tenance on the vehicle with the dump body in the raised position, the body-up retention cable must be installed. The Komatsu body-up retention cable can only be used with a Komatsu body. Non-OEM dump bodies may not accommodate the Komatsu body-up retention cable. The end user must ensure that a proper cable/sling is used. 1. To hold the dump body in the raised position, raise the body to it's maximum height.
