Warning tag part number : 09963-03000 The Komatsu body-up safety sling can only be used with a Komatsu body. Non-OEM body may not accommodate the Komatsu body-up safety sling. The end user must ensure that a proper cable/sling is used. 1. Raise the body to its maximum height. 2. Install two shackles (2, Figure 20-1) and body retention sling (3) between rear body ear (1) and axle housing. Stopping The Engine Before Service Before performing inspections or maintenance, stop the machine on firm, flat ground.
Lower the dump body, place the directional control lever to the PARK position (this will apply the parking brake), and turn the key switch to the OFF position and wait for the engine to stop. 3. Secure the shackle pins with cotter pins. 4. After service work is completed, reverse the installation steps to remove the sling. Wait two minutes after the engine has stopped, and if no warning lights illuminate, then turn the battery disconnect switches to the OFF position. Verify that the disconnects are functioning. Place wheel chocks around the wheels to prevent the truck from rolling.
If the engine must be operated during maintenance, always move the directional control lever to the PARK position (this will apply the parking brake). Always perform this work with two people. One person must be 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. Apply the propel lockout lever to prevent the truck from moving if the engine must operate during maintenance. When servicing the machine, use care not to touch any moving parts. Never wear loose clothing. When performing service with the dump body raised, always place the dump lever in the HOLD position, and apply the lock (if equipped).
