General Hazard Information
Attach a Do Not Operate, SEHS7332, or similar warning tag to start switch or controls before servicing or repairing the machine. This tag is available from your Caterpillar dealer.Know the width of your attachments so proper clearance can be maintained when operating near fences, boundary obstacles, etc.Wear a hard hat, protective glasses and other protective equipment as required by job conditions.Do not wear loose clothing or jewelry that can catch on controls or other parts of the machine.Make certain all protective guards and covers are secured in place on the machine.Keep the machine, especially the deck, walkways and steps, free of foreign material, such as debris, oil, tools and other items which are not part of the machine.Secure all loose items such as lunch boxes, tools and other items which are not part of the machine.Know the appropriate work-site hand signals and who gives them. Accept signals from one person only.Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death. Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.Never put maintenance fluids into glass containers. Use all cleaning solutions with care.Report all needed repairs.Do not allow unauthorized personnel on the machine.Dual controls are always active (several functions may be controlled at both sides of the control panel).Perform all maintenance unless otherwise specified as follows: * Park the machine on level ground.* Move the rotor switch to the OFF position and reduce engine speed.* Raise the mainframe to the full UP position and install all four leg supports. See, Installing Leg Supports, in the Machine Service section.* Apply the parking brake. Stop the engine.* Turn engine start switch key off and remove the key.* Turn the disconnect switch key off and remove the key.Pressure Air
Pressure air can cause personal injury. When using pressure air for cleaning, wear a protective face shield, protective clothing and protective shoes.The maximum air pressure must be below 205 kPa (30 psi) for cleaning purposes.Fluid Penetration
Always use a board or cardboard when checking for a leak. Escaping fluid under pressure, even a pin-hole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin, it must be treated by a doctor familiar with this type of injury immediately.Asbestos Information
This Caterpillar machine and replacement parts shipped from the factory are asbestos free. Caterpillar recommends the use of only genuine Caterpillar replacement parts. If any replacement parts containing asbestos are used, the following guidelines should be used in handling these parts and asbestos debris. Caterpillar products and genuine Caterpillar replacement parts do not contain asbestos.Caution should be used to avoid breathing dust that might be generated when handling components containing asbestos fibers. If this dust is inhaled, it can be hazardous to your health. Components that could be installed in Caterpillar products that might contain asbestos fibers are brake pads, brake band and lining assemblies, clutch plates and some gaskets. The asbestos used in these components is usually bound in a resin or sealed in some way. Normal handling is not hazardous as long as airborne dust which contains asbestos is not generated. If dust which can contain asbestos is present, there are several common sense guidelines that should be followed.* Never use compressed air for cleaning. Avoid brushing or grinding of asbestos containing materials.* For clean up, use wet methods or a vacuum equipped with a high efficiency particulate air (HEPA) filter.* Use exhaust ventilation on permanent machining jobs.* Wear an approved respirator if there is no other way to control the dust.* Comply with applicable rules and regulations for the work place (for example in the U.S.A., OSHA requirements as set forth in 29 CFR 1910.1001).* Follow environmental rules and regulations for disposal of asbestos. Avoid areas where asbestos particles might be in the air.Crushing or Cutting Prevention
Support equipment and attachments properly when working beneath them. Do not depend on hydraulic cylinders to hold them up. An attachment can fall if a control is moved, or if a hydraulic line breaks.Do not ship this machine without using the conveyor shipping supports. Failure to support the conveyor during shipping will result in structural damage (or failure) of the conveyor mounting support system.The following practices will also prevent structural damage (failure) to the conveyor mounting support system.* When raising or lowering the machine, keep the machine as level as possible to prevent the conveyor from coming in contact with the ground.* When loading trucks, every precaution should be made to prevent the trucks from hitting the conveyor.Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified.Where there are attachment linkages, the clearance in the linkage area will increase or decrease with movement of the attachment.Stay clear of all rotating and moving parts.Keep objects away from moving fan blades. They will throw or cut any object or tool that falls or is pushed into them.Do not use a kinked or frayed wire rope cable. Wear gloves when handling wire rope cable.Retainer pins, when struck with force, can fly out and injure nearby persons. Make sure the area is clear of people when driving retainer pins.Wear protective glasses when striking a retainer pin to avoid injury to your eyes.Chips or other debris can fly off objects when struck. Make sure no one can be injured by flying debris before striking any object.Wear protective glasses during removal and installation of rotor bits due to metal chipping to avoid injury to your eyes.Burn Prevention
Coolant
At operating temperature, the engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Steam can cause personal injury.Check the coolant level only after the engine has been stopped and the fill cap is cool enough to remove with your bare hand.Remove the cooling system filler cap slowly to
