8. PRECAUTIONS FOR MAINTENANCE ¤ WARNING: For reasons of safety, always follow these safety precautions. 8.1 BEFORE CARRYING OUT MAINTENANCE NOTIFICATION OF FAILURE Carrying out maintenance not described in the Komatsu operation and maintenance manual may lead to unexpected failures. Please contact your Komatsu distributor for repairs. 1-20 WARNING TAG ‡ ALWAYS attach the “DO NOT OPERATE” warning tag to the blade 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.
‡ If others start the engine, or touch or operate the blade control lever while you are performing service or maintenance, you could suffer serious injury or death. Warning tag Part No. 09963-03000 DO NOT operate When this plate is not being used keep it in the storage compartment. 09963-03000 CLEAN BEFORE INSPECTION AND MAINTENANCE ‡ Clean the machine before carrying out inspection and maintenance. This will ensure that dirt does not get into the machine and will also ensure that maintenance can be carried out safely.
‡ If inspection and maintenance are carried out with the machine still dirty, it will be difficult to find the location of problems, and there is also the danger that you will get dirty or mud in your eyes, and that you will slip and injure yourself. ‡ When washing the machine, always do as follows. • Wear non-slip shoes to prevent yourself from slipping on the wet surface. • When using high-pressure steam to wash the machine, always wear protective clothing. This will protect you from being hit by high-pressure water, and cutting your skin or getting mud or dust into your eyes. • Do not spray water directly on to the electrical system (sensors, connectors) 1.
If water gets into the electrical system, there is danger that it will cause defective operation and malfunction. A0055150
