Hoses wear out over time, even if they do not show any symptom of wear. • Regardless of the replacement schedule, replace im- mediately if a symptom of wear is found. Explosionproof lighting To prevent an ignition or explosion, use explosion-proof lights when inspecting fuel, oil, coolant or battery fluid. Prohibit access by unauthorized persons Do not allow unauthorized personnel in the work area while working. Take particular care that no unauthorized person is present when grinding, welding or using a hammer. Prepare the work area • Select a level and firm ground on which to perform maintenance work. Make sure that the work area is light enough and well ventilated. • Straighten any obstacle or dangerous object, remove any spill of oil or grease and clean the work area. When the canopy is tilted up • If the canopy is raised or lowered while the engine is moving, the machine may accidentally start moving, resulting in severe injury to the maintenance person- nel. Make sure that the working equipment has been lowered to the ground and the engine has been turned off before raising/lowering the canopy. • When the canopy is tilted up, firmly secure the canopy with a stopper to prevent it from falling. Keep the machine clean • Clean the machine before performing maintenance and try to keep it clean. • Before washing, cover the electrical parts with vinyl to prevent water from entering, as this could cause a short-circuit or malfunction. Do not use water or steam to wash the battery, sensors, connectors or the opera- tor’s seat area. Stop the engine before performing maintenance Make sure the engine is stopped before starting inspec- tion or maintenance. If maintenance must be performed with the engine running, always work as a 2-person team, communicating with each other. • One of them must sit at the operator’s seat and stop the engine whenever necessary. He/she must take care not to touch the lever or pedal unless necessary. • The one who performs maintenance must make sure to keep his/her body or clothing away from the moving part of the machine. 1BAA04Z 1BAA05Z 1BAA06Z

- 8. SAFETY SAFETY PRECAUTIONS 1-6 1 Caution when filling with fuel or oil • Keep away from heat, sparks and flame while filling with fuel or oil. • Never remove the fuel cap or try to fuel when the en- gine is running or still hot. • Maintain control of the fuel filler nozzle when filling the tank. • Refill with fuel or oil outdoors or in a well ventilated place, with the engine turned off. • Clean up spilled fuel or oil immediately. • Do not overfill the tank. • Firmly tighten the fuel cap or oil cap. If the fuel cap is lost, replace it only with the original manufacturer’s ap- proved cap. Use of a non-approved cap without prop- er venting may result in pressurization of the tank. • Never use fuel for cleaning. • Use the correct grade of fuel for the operating season. Handling of hoses Oil leak or fuel leak can cause a fire. • Do not twist, bend or hit the hoses. • Never use twisted, bent or cracked pipes, tubes or hoses; otherwise, they may burst. • Retighten loose connections. Be careful with hot and pressurized components Before performing inspection and maintenance, stop the engine and allow the machine to cool down. • The engine, muffler, radiator, hydraulic lines, sliding parts and many other parts of the machine are hot im- mediately after the engine is stopped. Wait until it cools before making any inspection or adjustments. • The engine coolant, hydraulic oil and other oils are also hot and under high pressure. Touching these liq- uids will cause burns. Handling of radiator Do not remove the radiator cap when the coolant is hot. Wait until it cools down, and then remove the radiator cap by loosening it slowly to release the internal pressure. 1BAA11Z 1BAA12Z 1BAA13Z
- 9. SAFETY SAFETY PRECAUTIONS 1-7 1 Be careful with oils under pressure Pressure is maintained in the hydraulic circuit long after the engine has been shut down. • Do not fill with, dispose of fuel/oil, or perform the in- spection and maintenance until the internal pressure is completely released. • The hydraulic oil escaping from a small hole can be hazardous if contacted. It is under high enough pres- sure to penetrate the skin or eyes and cause serious injury. If leak is suspected, protect your eyes and skin by wearing protective glasses and thick gloves to search for a leak. Also use a paperboard or plywood to keep your skin from oil spurting. If oil penetrates the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury. Release internal pressure before working on the hydraulic system Oil may spurt out if caps or filters are removed or pipes are disconnected before releasing the pressure in the hydraulic system. • Gradually loosen the vent plug to release the internal pressure of the hydraulic oil tank. • Move all the control levers and pedals several times in all directions to release the pressure from the circuit of the working equipment (for link type controls). • When removing plugs or screws, or when disconnect- ing hoses, stand to the side and loosen them slowly to gradually release the internal pressure before remov- ing. Be careful with grease under pressure In the track adjuster, the grease has been injected under high pressure. If the tension is adjusted without following the prescribed procedure, the grease discharge valve may fly off, resulting in injury. • Loosen the grease discharge valve slowly. • Do not put your face, arms, legs or body in front of the grease discharge valve. Handling of the accumulator Be sure to handle the high-pressure nitrogen gas en- closed in the accumulator with care according to proce- dure. If handled incorrectly, it could explode and cause serious injury. Strictly observe the following precautions: • Do not disassemble. • Do not allow flame near it or throw it into a fire. • Do not drill, weld or fuse. • Do not subject it to physical shock such as hitting, roll- ing or dropping. • Before disposing of the unit, the sealed gas must be drained. Contact your sales or service dealer for help with this. Disconnect the battery Disconnect the wiring from the both terminals (+ and -) on the battery before working on the electrical system or doing electric welding. Otherwise, short-circuit and ex- plosion of the battery can result. 1BAA14Z 1BAA15Z 1BAA16Z
- 10. SAFETY SAFETY PRECAUTIONS 1-8 1 Use caution when handling batteries • Batteries contain sulfuric acid which will damage eyes or skin if contacted. • If eye contact occurs, flush immediately with clean water and get prompt medical attention. • If accidentally swallowed, drink large quantities of water or milk and call a physician immediately. • If acid contacts skin or clothing, wash off immedi- ately with a lot of water. • Wear protective glasses and gloves when working with batteries. • Batteries generate flammable hydrogen gas which may explode. Keep away from flame and sparks. • Do not use or charge the battery when the electrolyte level is lower than the lower limit: otherwise, it could cause an explosion. • Be sure to stop the engine by turning off the starter switch before inspecting or handling the battery. • Be careful not to let metal tools (or any metal objects) such as a hammer or spanner come into contact with the battery terminals. • When disconnecting the battery wiring, always discon- nect it from the earth side (-). When connecting, con- nect the earth side last. • Loose battery terminals may result in sparks. Be sure to fasten terminals tightly. • Make sure the battery caps are tightened securely. • Do not charge a battery or jump-start the engine if the battery is frozen; otherwise it may explode. Warm the frozen battery to 15°C (59°F) before use. Have a service agent repair welding cracks or other damage Ask a service agent to make any repairs that require welding. If the agent is unavailable, make sure the weld- ing is done by a qualified person in a properly equipped workplace. Checks after maintenance • Gradually raise the engine speed from low idle to max- imum and check that no oil or water is leaking from the parts serviced. • Move the controls and check that the machine is oper- ating properly. Disposing of wastes • Always collect oil that is drained from the machine in containers. Improperly disposed waste oil can cause environmental harm. • Follow appropriate laws and regulations when dispos- ing of harmful objects such as oil, fuel, coolant, sol- vent, filters and batteries. 1BAA17Z 1BAA18Z
- 11. SAFETY CAUTIONS WHEN WORKING 1-9 1 A0AZ00 CAUTIONS WHEN WORKING When disassembling or assembling • Clean the machine before disassembly. • Check the following items and record the results: a. Model, machine serial number, hour meter. b. Reason for repair, repair history. c. Are the filters dirty? d. The conditions of the fuel and oil. e. Any damage or looseness to any part? • Where necessary, draw alignment indicators to avoid assembly errors. To avoid misconnection, place indi- cators such as reference tags on pipes. • Clean all disassembled parts and new parts, arrange them neatly, and place indicators as necessary. • Be sure to replace all seals and cotter pins with new ones. • Keep those parts that should not come in contact with water or oil away from those with oil on the surface. • When installing bearings, bushings and oil seals, a press tool should be used. If a hammer is used, use a cushioning material to avoid damage. • Wipe all joining surfaces clean until there is no dirt or dust adhering to them. • Wrap the thread tight with seal tape starting 1 or 2 threads away from the thread end. The tape should be overlapped by about 10 mm (0.39 in). When removing/installing the hydraulic unit • Make sure that the temperature of the hydraulic oil has dropped and is cool enough to work with. • To prevent the hydraulic oil from escaping under pres- sure, release the residual pressure in the piping. • Be sure to install caps or plugs on all openings in the hydraulic unit to prevent dirt from getting into the unit through them. • The hydraulic oil adhering to the unit is often mistaken for an oil leak, so wipe off the unit thoroughly. • Be sure that no damage is caused to the plating on the rod in the hydraulic cylinder. • Removal and installation of the hydraulic cylinder should be done with the rod fully retracted. • Be sure to bleed the air after installing the hydraulic cylinder. ( “4. Disassembly and assembly: Cylin- der”) • Always bleed the air when hydraulic oil is changed or a hydraulic device is replaced.( “4. Disassembly and assembly: Drive system”)
- 12. SAFETY CAUTIONS WHEN WORKING 1-10 1 A0AZ00 When connecting/disconnecting the hoses or pipes • When hydraulic hoses or pipes are connected, tighten them once to the prescribed torque, then loosen them slightly and retighten them to the prescribed torque. a. Tighten the fittings after the installation surfaces fit snugly together. b. The above procedures do not apply to fittings with seal tape. • Use two spanners, one to tighten/loosen and the other to secure the mating hose/pipe to ensure that the hose is not twisted. • After connecting the hydraulic hoses or pipes, apply the maximum working pressure five or six times to check for leakage. • If high pressure, vibration or shock is applied to a twist- ed hose, oil leak, hose breakage or damage to the hose fitting can result. • Be sure that the hydraulic hoses are not contacting sharp objects or each other. This could cause surface flaws on the hoses, resulting in breakage. Handling of seals • Clean the grooves for O-rings and remove any burrs. • Be careful not to twist the O-rings. If twisted, remove it with your fingertips. • When inserting, be careful not to damage the seal. • Handling of the floating seal a. After removal, wipe all oil off the O-ring and housing of the floating seal. b. When assembling, apply a thin coating of gear oil to the contact surface of the housing, c. After assembly, turn the seal two or three times to get it to fit snugly. • Apply grease to the lip of the oil seal. a. This is to prevent wear from occurring upon first start up after assembly. Pressure adjustment for hydraulic devices • The pressure for hydraulic devices is adjusted by Takeuchi Mfg. to optimal conditions before product- sare shipped for delivery to the customer. The pres- surewill not need to be adjusted again except in prod- ucts that undergo disassembly and assembly procedures. 1CAA03Z 1CAA04Z
