SECTION 2 SAFETY PRECAUTIONS Page 8 GENERAL MAINTENANCE PRECAUTIONS Refer to the parts catalog for this machine. Tighten fasteners to the proper torque. When cutting, grinding, pounding, prying, or whenever material could fly or fall, wear proper protective equipment (such as goggles, hard hat, safety shoes, and heavy gloves). During servicing do not allow anyone in the operator's compartment who is not trained and assisting in the servicing. When it is necessary to make any checks or adjustments with the engine running, use two people. A trained operator must be at the controls to safeguard the mechanic making the checks or adjustments.
Be sure the transmission shift lever is locked in neutral (N), the parking brake is applied and the frame halves are locked together. Never stand near the bucket or tires while the engine is running. If compressed air or water under pressure is used for cleaning the parts, wear safety goggles. Limit air pressure to 200 kPa and water pressure to 270 kPa. Never run the engine when cleaning or lubricating the machine because serious injury could result from contacting moving parts. Use a nontoxic, nonflammable commercial solvent for cleaning parts unless otherwise specified. Avoid use of gasoline, diesel fuel, kerosene or other flammable solvents for cleaning parts.
Never place these solvents in an open pan. Use gloves and safety goggles when draining hot fluids. For your safety lower the bucket before servicing the machine. Be sure no one is standing near the bucket when it is being lowered. Do not service the air conditioning system (if equipped) unless you are completely familiar with air conditioning and the safety precautions for handling liquid refrigerant which can cause severe frostbite. Contact the Authorized Distributor of Construction Equipment Before working on the engine or electrical system turn off the master switch and take the ignition key out. Tag the cables and controls to warn against starting.
Keep the engine exhaust manifold(s) and exhaust system clear of combustible material to reduce the chance of fire. Never remove any guards or shields with the engine running because of the danger of contacting rotating parts. Before working on the hydraulic system, be sure the system pressure is relieved. To do so lower the bucket on the ground, move boom control lever in float position and switch off the engine. Do not use hands to search for hydraulic leaks. Hydraulic oil escaping under pressure from a very small hole can be almost invisible yet have sufficient force to penetrate the skin. Use a piece of cardboard or wood to search for suspected leaks.
If injured by escaping oil, see a doctor immediately because of the possibility of infection or reaction to the oil. Never work or walk under a raised bucket without proper blocking. OM560C99/1E DRESSTA
