Crushing or Cutting Prevention

Performance of Maintenance Unless otherwise specified, maintenance should be performed with the machine parked on level ground, the blade resting on the ground, the transmission control lever in NEUTRAL, the parking brake engaged, the engine stopped, and the electrical disconnect switch in the OFF position. 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 immediately by a doctor familiar with this type of injury. Crushing or Cutting Prevention Support equipment and attachments properly when working beneath them. Do not depend on hydraulic cylinders to hold them up. Any attachment can fall if a control is moved, or if a hydraulic line breaks. 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 the 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. Rollover Protective Structure (ROPS) or Falling Objects Protective Structure (FOPS) ROPS or FOPS are guards located above the operator's compartment and secured to the machine. To avoid any possible weakening of the ROPS or FOPS, consult TACOM or any Caterpillar dealer before altering, adding weight to, welding on, or cutting or drilling holes into the structure. Any alteration not specifically authorized by Caterpillar invalidates Caterpillar's ROPS and FOPS certification. The protection offered by the ROPS/FOPS will be impaired if it has been subjected to structural damage. Structural damage can be caused by an overturn accident, by falling objects, etc. 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 fill cap slowly to relieve pressure. Cooling system additive contains alkali that can cause personal injury. Avoid contact with the skin, eyes, and mouth. Allow cooling system components to cool before draining. Oils Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin. At operating temperature, the hydraulic tank is hot and can be under pressure. 10 Safety Section Safety TM5-2430-200-10
