OM2034 10/04 General Safety - Section 20 Page 20-11 PRECAUTIONS FOR MAINTENANCE BEFORE PERFORMING MAINTENANCE Warning Tag If others start the engine or operate the controls while you are performing service or lubrication, you could suffer serious injury or death. ALWAYS attach the WARNING TAG to the control lever in the operator's cab to alert others that you are working on the machine. Attach additional warning tags around the machine, if necessary. These tags are available from your Komatsu distributor. (Part No. 09963-03000) Proper Tools Use only tools suited to the task. Using damaged, low quality, faulty, or makeshift tools could cause personal injury.
Stopping The Engine Before Service When carrying out inspection or maintenance, always stop the machine on firm flat ground, lower the dump body, then stop the engine. If the engine must be run during service, such as when cleaning the radiator, always move the shift control lever to the Neutral (N) position and set the parking brake lever to the PARKING position. Always carry out the work with two people. One person should sit on the operator's seat to stop the engine if necessary. NEVER move any controls not needed to operate. When servicing the machine, be careful not to touch any moving part or get clothing caught. Put blocks under the wheels.
When carrying out service with the dump body raised, always place the dump lever at the HOLD position, and apply the lock (if equipped). Install the body-up safety pins (or cable) securely. Securing The Dump Body Any time personnel are required to perform mainte- nance on the vehicle with the dump body in the raised position, the body-up retention cable MUST be installed. 1. To hold the dump body in the up position, raise the body to it's maximum height. 2. Remove cable (3) from its stored position on the body, and install between rear body ear (1) and axle housing ear (4). 3. Secure the cable clevis pins with cotter pins. 4.
Return the cable to stored position (2) after mainte- nance is complete.
