Illustration 1 g00104545Attach a "Do Not Operate" warning tag or a similar warning tag to the start switch or to the controls before you service or repair the equipment. These warning tags (Special Instruction, SEHS7332) are available from your Cat dealer.Know the width of your equipment to maintain proper clearance when you operate the equipment near fences or near boundary obstacles.Be aware of high-voltage power lines and power cables that are buried. If the machine comes in contact with these hazards, serious injury or death may occur from electrocution.
Illustration 2 g00702020Wear a hard hat, protective glasses, and other protective equipment, as required.Do not wear loose clothing or jewelry that can snag on controls or on other parts of the equipment.Make sure that all protective guards and all covers are secured in place on the equipment.Keep the equipment free from foreign material. Remove debris, oil, tools, and other items from the deck, from walkways, and from steps.Secure all loose items such as lunch boxes, tools, and other items that are not a part of the equipment.Know the appropriate work site hand signals and the personnel that are authorized to give the hand signals. Accept hand signals from one person only.Never put maintenance fluids into glass containers. Drain all liquids into a suitable container.Obey all local regulations for the disposal of liquids.Use all cleaning solutions with care. Report all necessary repairs.Do not allow unauthorized personnel on the equipment.Pressurized Air and Water
Pressurized air and/or water can cause debris and/or hot water to be blown out which could result in personal injury.When pressurized air and/or pressurized water is used for cleaning, wear protective clothing, protective shoes, and eye protection. Eye protection includes goggles or a protective face shield.The maximum air pressure for cleaning purposes must be reduced to 205 kPa (30 psi).The aforementioned air pressure should be used when the nozzle is deadheaded and the nozzle is used with an effective chip deflector and personal protective equipment. The maximum water pressure for cleaning purposes must be below 275 kPa (40 psi).Trapped Pressure
Pressure can be trapped in a hydraulic system. Releasing trapped pressure can cause sudden machine movement or attachment movement. Use caution if you disconnect hydraulic lines or fittings. High-pressure oil that is released can cause a hose to whip. High-pressure oil that is released can cause oil to spray. Fluid penetration can cause serious injury and possible death.Fluid Penetration
Pressure can be trapped in the hydraulic circuit long after the engine has been stopped. The pressure can cause hydraulic fluid or items such as pipe plugs to escape rapidly if the pressure is not relieved correctly.Do not remove any hydraulic components or parts until pressure has been relieved or personal injury may occur. Do not disassemble any hydraulic components or parts until pressure has been relieved or personal injury may occur. Refer to this System Pressure Release section of this manual for any procedures that are required to relieve the hydraulic pressure.
