3.7 Troubleshooting Operation When engine cannot be used When towing a machine with the engine stopped, use the follow- ing procedure. 1. The transfer oil does not lubricate the system, so remove the front and rear drive shafts. If necessary, block the tires to prevent the machine from moving. 2. The steering cannot be operated, so remove the steering cylinder. Even if the brakes are in good condition, the brakes can only be used a limited number of times. There is no change in the operating force for the brake pedal, but the braking force is reduced each time the pedal is depressed. 3. Connect the towing equipment securely.
When carrying out towing operations, use two machines of at least the same class as the machine being towed. Connect one machine each to the front and rear of the machine being towed, then remove the blocks from the tires and tow the machine. Emergency travel operation The normal gear shifting operation is carried out by electric sig- nals. If there should be a failure in the electrical system and the machine does not move, please contact your Komatsu distribu- tor to have the machine moved. NOTE Always request your Komatsu distributor to carry out the emergency travel operation. 3-112 WA150-5H – VEAM934100
