Also, do not drill holes in the ROPS in order to mount the fire extinguisher on the ROPS. i01557411 Tire Information SMCS Code: 7000 Explosions of air inflated tires have resulted from heat-induced gas combustion inside the tires. Explosions can be caused by heat that is generated by welding, by heating rim components, by external fire, or by excessive use of brakes. A tire explosion is much more violent than a blowout. The explosion can propel the tire, the rim components, and the axle components as far as 500 m (1500 ft) or more from the machine. Both the force of the explosion and the flying debris can cause property damage, personal injury, or death. To avoid overinflation, proper nitrogen inflation equipment and training in the usage of the equipment are necessary. A tire blowout or a rim failure can result from improper equipment or from misused equipment. When you inflate a tire, stand behind the tread and use a self-attaching chuck. Servicing tires and rims can be dangerous. Only trained personnel that use proper tools and proper procedures should perform this maintenance. If correct procedures are not used for servicing tires and rims, the assemblies could burst with explosive force. This explosive force can cause serious personal injury or death. Carefully obey the specific instructions from your tire dealer. i01122596 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. i03140043 Illustration 27 g00337832 (A) At least 15 m (50 ft) (B) At least 500 m (1500 ft) Do not approach a warm tire. Maintain a minimum distance, as shown. Stay outside the shaded area in Illustration 27. Do not use water or calcium as a ballast for the tires. Dry nitrogen gas is recommended for inflation of tires. If the tires were originally inflated with air, nitrogen is still preferred for adjusting the pressure. Nitrogen mixes properly with air. Nitrogen inflated tires reduce the potential of a tire explosion because nitrogen does not aid combustion. Nitrogen helps to prevent oxidation of the rubber, deterioration of rubber, and corrosion of rim components. Before Starting Engine SMCS Code: 1000; 7000 Start the engine only from the operator's compartment. Never short across the starter terminals or across the batteries. Shorting could bypass the engine neutral start system. Shorting could also damage the electrical system. 26 Safety Section Engine Starting SEBU7858-03 i03565626 Engine Starting SMCS Code: 1000; 7000 If a warning tag is attached to the engine start switch or to the machine controls, do not start the engine.

SEBU7858-03 27 Safety Section Visibility Information i03162317 i03641204 Visibility Information Restricted Visibility SMCS Code: 7000 SMCS Code: 7000 Before you start the machine, perform a walk-around inspection in order to ensure that there are no hazards around the machine. The size and the configuration of this machine may result in areas that can not be seen when the operator is seated. Illustration 30 provides an approximate visual indication of areas of significant restricted visibility. Illustration 30 indicates restricted visibility areas at ground level inside a radius of 12.00 m (40 ft) from the operator on a machine without the use of optional visual aids. This illustration does not provide areas of restricted visibility for distances outside a radius of 12.00 m (40 ft). While the machine is in operation, constantly survey the area around the machine in order to identify potential hazards as hazards become visible around the machine. Your machine may be equipped with visual aids. Some examples of visual aids are Closed Circuit Television (CCTV) and mirrors. Before operating the machine, ensure that the visual aids are in proper working condition and that the visual aids are clean. Adjust the visual aids using the procedures that are located in this Operation and Maintenance Manual. If equipped, the Work Area Vision System shall be adjusted according to Operation and Maintenance Manual, SEBU8157, “Work Area Vision System”. It may not be possible to provide direct visibility on large machines to all areas around the machine. Appropriate job site organization is required in order to minimize hazards that are caused by restricted visibility. Job site organization is a collection of rules and procedures that coordinates machines and people that work together in the same area. Examples of job site organization include the following: This machine may be equipped with optional visual aids that may provide visibility to some of the restricted visibility areas. Refer to this Operation and Maintenance Manual, “Mirror” for more information on additional visibility. If your machine is equipped with cameras, refer to this Operation and Maintenance Manual, “Camera” for more information on additional visibility.

Special configurations for different ambient temperatures may be available. Consult your Caterpillar dealer for additional information on special configurations of your machine. Machine Operation Only operate the machine while you are in a seat. The seat belt must be fastened while you operate the machine. Only operate the controls while the engine is running. While you operate the machine slowly in an open area, check for proper operation of all controls and all protective devices. Before you move the machine, you must make sure that no one will be endangered. Do not allow riders on the machine unless the machine has the following equipment: • additional seat • additional seat belt • Rollover Protective Structure (ROPS) Never use the work tool for a work platform. Note any needed repairs during machine operation. Report any needed repairs. Do not operate the machine on ground conditions that could result in the seat suspension travel stops being contacted and do not operate the machine at travel speeds that could result in the seat suspension travel stops being contacted. Operating this machine in very rough ground conditions or at travels speeds not suitable for the ground conditions may result in excessive seat vertical travel with impact of the suspension against the travel stops, which may cause injury. In order to minimize impact loading on the operator, properly adjust the seat controls for the operator weight and height. Refer to Operation and Maintenance Manual, “Seat” for more information. Carry attachments approximately 40 cm (15 inches) above ground level. Do not go close to the edge of a cliff, an excavation, or an overhang. If the machine begins to sideslip downward on a grade, immediately remove the load and turn the machine downhill. Avoid any conditions that can lead to tipping the machine. The machine can tip when you work on hills, on banks and on slopes. Also, the machine can tip when you cross ditches, ridges or other unexpected obstructions. Avoid operating the machine across the slope. When possible, operate the machine up the slopes and down the slopes. Maintain control of the machine. Do not overload the machine beyond the machine capacity. Never straddle a wire cable. Never allow other personnel to straddle a wire cable. Before you maneuver the machine, make sure that no personnel are between the machine and attachments. Know the maximum dimensions of your machine. Always keep the Rollover Protective Structure (ROPS) installed during machine operation. i02624835 Engine Stopping SMCS Code: 1000; 7000 Do not stop the engine immediately after the machine has been operated under load. This can cause overheating and accelerated wear of engine components. SEBU7858-03 29 Safety Section Parking After the machine is parked and the parking brake is engaged, allow the engine to run for two minutes before shutdown. This allows hot areas of the engine to cool gradually. i03370980 Parking A well trained operator that follows the instructions in the Operation and Maintenance Manual has the greatest impact on stability. Operator training provides a person with the following abilities: observation of working and environmental conditions, feel for the machine, identification of potential hazards, and operating the machine safely by making appropriate decisions. SMCS Code: 7000 When you work on side hills and when you work on slopes, consider the following important points: Park the machine on a level surface. If you must park on a grade, chock the machine's wheels with suitable chocks. Take into account the following: Speed of travel – At higher speeds, forces of inertia tend to make the machine less stable. • tire size Roughness of terrain or surface – The machine may be less stable with uneven terrain. • machine weight • ground conditions Apply the service brake in order to stop the machine. Move the transmission control (lever) to the NEUTRAL position. Move the throttle control to the LOW IDLE position. Engage the parking brake. Lower all equipment to the ground. Activate any control locks. Stop the engine. Turn the engine start switch to the OFF position and remove the engine start switch key. Turn the battery disconnect switch to the OFF position. Remove the disconnect switch key if you do not operate the machine for an extended period of time. This will prevent drainage of the battery. A battery short circuit, any current draw from certain components, and vandalism can cause drainage of the battery. Direction of travel – Avoid operating the machine across the slope. When possible, operate the machine up the slopes and operate the machine down the slopes. Place the heaviest end of the machine uphill when you are working on an incline. Mounted equipment – Balance of the machine may be impeded by the following components: equipment that is mounted on the machine, machine configuration, weights, and counterweights. Nature of surface – Ground that has been newly filled with earth may collapse from the weight of the machine. Surface material – Rocks and moisture of the surface material may drastically affect the machine's traction and machine's stability. Rocky surfaces may promote side slipping of the machine. Slippage due to excessive loads – This may cause downhill tracks or downhill tires to dig into the ground, which will increase the angle of the machine. Width of tracks or tires – Narrower tracks or narrower tires further increase the digging into the ground which causes the machine to be less stable. i02780235 Slope Operation SMCS Code: 7000 Machines that are operating safely in various applications depend on these criteria: the machine model, configuration, machine maintenance, operating speed of the machine, conditions of the terrain, fluid levels, and tire inflation pressures. The most important criteria are the skill and judgment of the operator. Implements attached to the drawbar – This may decrease the weight on the uphill tracks. This may also decrease the weight on the uphill tires. The decreased weight will cause the machine to be less stable. Height of the working load of the machine – When the working loads are in higher positions, the stability of the machine is reduced. Operated equipment – Be aware of performance features of the equipment in operation and the effects on machine stability. 30 Safety Section Equipment Lowering with Engine Stopped SEBU7858-03 Operating techniques – Keep all attachments or pulled loads low to the ground for optimum stability. Machine systems have limitations on slopes – Slopes can affect the proper function and operation of the various machine systems. These machine systems are needed for machine control on slopes. Hearing protection may be needed when the machine is operated with an open operator station for extended periods or in a noisy environment. Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors and windows are open for extended periods or in a noisy environment. Note: Safe operation on steep slopes may require special machine maintenance. Excellent skill of the operator and proper equipment for specific applications are also required. Consult the Operation and Maintenance Manual sections for the proper fluid level requirements and intended machine use. The average exterior sound pressure level is 86 dB(A) when the “SAE J88Feb06 - Constant Speed Moving Test” procedure is used to measure the value for the standard machine. The measurement was conducted under the following conditions: distance of 15 m (49.2 ft) and “the machine moving forward in an intermediate gear ratio”. i01329161 The exterior sound power level is 115 dB(A) when the value is measured according to the static pressure test procedures and the conditions that are specified in “ISO 6393:2008”. Equipment Lowering with Engine Stopped SMCS Code: 7000 Before lowering any equipment with the engine stopped, clear the area around the equipment of all personnel. The procedure to use will vary with the type of equipment to be lowered. Keep in mind most systems use a high pressure fluid or air to raise or lower equipment. The procedure will cause high pressure air, hydraulic, or some other media to be released in order to lower the equipment. Wear appropriate personal protective equipment and follow the established procedure in the Operation and Maintenance Manual, “Equipment Lowering with Engine Stopped” in the Operation Section of the manual. i03596373 Sound Information and Vibration Information SMCS Code: 7000 S/N: DBD1-Up Sound Level Information The operator Equivalent Sound Pressure Level (Leq) is 81 dB(A) when “ANSI/SAE J1166 OCT 98” is used to measure the value for an enclosed cab. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed. Sound Level Information for Machines in European Union Countries and in Countries that Adopt the “European Union Directives” The static operator sound pressure level is 79 dB(A) when “ISO 6394:2008” is used to measure the value for an enclosed cab.

Information Concerning Whole Body Vibration Level This section provides vibration data and a method for estimating the vibration level for wheel scrapers. Note: Vibration levels are influenced by many different parameters. Many items are listed below. • Operator training, behavior, mode, and stress SEBU7858-03 31 Safety Section Sound Information and Vibration Information • Job site organization, preparation, environment, weather, and material • Machine type, quality of the seat, quality of the suspension system, attachments, and condition of the equipment It is not possible to get precise vibration levels for this machine. The expected vibration levels can be estimated with the information in Table 1 in order to calculate the daily vibration exposure. A simple evaluation of the machine application can be used. Estimate the vibration levels for the three vibration directions. For typical operating conditions, use the average vibration levels as the estimated level. With an experienced operator and smooth terrain, subtract the Scenario Factors from the average vibration level in order to obtain the estimated vibration level. For aggressive operations and severe terrain, add the Scenario Factors to the average vibration level in order to obtain the estimated vibration level. Note: All vibration levels are in meter per second squared.

Consult your local Caterpillar dealer for more information about machine features that minimize vibration levels. Consult your local Caterpillar dealer about safe machine operation. Use the following web site in order to find your local dealer: Caterpillar, Inc. www.cat.com SEBU7858-03 33 Safety Section Operator Station i03634321 Operator Station SMCS Code: 7000 S/N: DBD1-Up Any modifications to the inside of the operator station should not project into the operator space or into the space for the companion seat (if equipped). The addition of a radio, fire extinguisher, and other equipment must be installed so that the defined operator space and the space for the companion seat (if equipped) is maintained. Any item that is brought into the cab should not project into the defined operator space or the space for the companion seat (if equipped). A lunch box or other loose items must be secured. Objects must not pose an impact hazard in rough terrain or in the event of a rollover. i01992325 Guards (Operator Protection) SMCS Code: 7000 There are different types of guards that are used to protect the operator. The machine and the machine application determines the type of guard that should be used. A daily inspection of the guards is required in order to check for structures that are bent, cracked or loose. Never operate a machine with a damaged structure. The operator becomes exposed to a hazardous situation if the machine is used improperly or if poor operating techniques are used. This situation can occur even though a machine is equipped with an appropriate protective guard. Follow the established operating procedures that are recommended for your machine. Rollover Protective Structure (ROPS), Falling Object Protective Structure (FOPS) or Tip Over Protection Structure (TOPS) The ROPS/FOPS Structure (if equipped) on your machine is specifically designed, tested and certified for that machine. Excavators are not equipped with ROPS structures. Any alteration or any modification to the ROPS/FOPS Structure could weaken the structure. This places the operator into an unprotected environment. Modifications or attachments that cause the machine to exceed the weight that is stamped on the certification plate also place the operator into an unprotected environment. Excessive weight may inhibit the brake performance, the steering performance and the ROPS. The protection that is offered by the ROPS/FOPS Structure will be impaired if the ROPS/FOPS Structure has structural damage. Damage to the structure can be caused by an overturn, a falling object, a collision, etc. Do not mount items (fire extinguishers, first aid kits, work lights, etc) by welding brackets to the ROPS/FOPS Structure or by drilling holes in the ROPS/FOPS Structure. Welding brackets or drilling holes in the ROPS/FOPS Structures can weaken the structures. Consult your Caterpillar dealer for mounting guidelines. The Tip Over Protection Structure (TOPS) is another type of guard that is used on mini hydraulic excavators. This structure protects the operator in the event of a tipover. The same guidelines for the inspection, the maintenance and the modification of the ROPS/FOPS Structure are required for the Tip Over Protection Structure. Other Guards (If Equipped) Protection from flying objects and/or falling objects is required for special applications. Logging applications and demolition applications are two examples that require special protection. A front guard needs to be installed when a work tool that creates flying objects is used. Mesh front guards that are approved by Caterpillar or polycarbonate front guards that are approved by Caterpillar are available for machines with a cab or an open canopy. On machines that are equipped with cabs, the windshield should also be closed. Safety glasses are recommended when flying hazards exist for machines with cabs and machines with open canopies. If the work material extends above the cab, top guards and front guards should be used. Typical examples of this type of application are listed below: 34 Safety Section Guards • Demolition applications • Rock quarries • Forestry products Additional guards may be required for specific applications or work tools. The Operation and Maintenance Manual for your machine or your work tool will provide specific requirements for the guards. Consult your Caterpillar dealer for additional information. SEBU7858-03
