- · Remember that nearly all the fluids on the machine are flammable, including coolant and oils. Additionally, plastics, rubbers, fabrics, and resins in fiberglass panels are also flammable. i06688803 ## Fire Extinguisher Location SMCS Code: 7000; 7419 Illustration 54 <!-- image --> Make sure that a fire extinguisher is available. Be familiar with the operation of the fire extinguisher. Inspect the fire extinguisher and service the fire extinguisher regularly. Obey the recommendations on the instruction plate. The recommended location for mounting the fire extinguisher is on top of the machine. i01329108 ## Track Information SMCS Code: 4170; 7000 Track adjusting systems use either grease or oil under high pressure to keep the track under tension. Grease or oil under high pressure coming out of the relief valve can penetrate the body causing injury or death. Do not watch the relief valve to see if grease or oil is escaping. Watch the track or track adjustment cylinder to see if the track is being loosened. The pins and bushings in a dry track pin joint can become very hot. It is possible to burn the fingers if there is more than brief contact with these components. ## Electrical Storm Injury Prevention SMCS Code: 7000 When lightning is striking in the vicinity of the machine, the operator should never attempt the following procedures: - · Mount the machine. - · Dismount the machine. If you are in the operator's station during an electrical storm, stay in the operator's station. If you are on the ground during an electrical storm, stay away from the vicinity of the machine. i00771840 ## Before Starting Engine SMCS Code: 1000; 7000 Start the engine only from the operator compartment. Never short across the starter terminals or across the batteries. Shorting could damage the electrical system by bypassing the engine neutral start system. Inspect the condition of the seat belt and of the mounting hardware. Replace any parts that are worn or da…

## 1.11 ENSURING VISIBILITY This machine is equipped with mirror and so on to ensure sufficient visibility, but there are areas where are outside the field of vision from the operator. Pay special attention to the invisible area and operate the machine. When traveling and working in poor visibility area, there is a possibility of injuries and accidents resulting in death because it is hard for operator to see the conditions of obstructions and the work area around the machine. Follow the followings when traveling and working in poor visibility area. - ・ When right visibility is poor due to attachment, raise the attachment to ensure visibility. - ・ Clean and adjust mirror at the pre-start inspection to ensure the visibility. - ・ When rearward visibility monitoring camera (option) is equipped with, clean the lens for clear vision. - ・ When the visibility can not be ensured sufficiently, provide a flagman in the working areas. Follow the instructions of flagman and pay attention to the signal. - ・ The signal shall be given by one flagman. - ・ When working in dark places, turn on the work light. And if required, provide additional lighting facilities to ensure good visibility. - ・ Stop working when it is impossible to ensure the visual field due to fog, snow or rain. <!-- image --> -Be sure to clean mirror before starting operation to ensure good visibility around machine. If the visibility around machine is not secured sufficiently, it may cause collisions and accidents resulting in injury and death. -To avoid the damage or break, do not install the mirror and so on to the handrail of cab entrance. If the mirror and so on is installed to the hand rail, the attaching part of handrail is stressed excessively. <!-- image --> -Do not attach the mirrors except the genuine mirrors (A, B, C and D). １
