(1) Understanding operating procedure Read OPERATION & MAINTENANCE MANUAL carefully to understand the operating procedure. (5) Choose a hard, level and safe place, and place the attachment on the ground securely. (2) Cleaning machines Remove soil, mud, and dust from the machine be- fore carrying it into the service shop to prevent loss of work efficiency, damage of parts, and difficulty in rust prevention and dust protection while reassem- bling. (6) Use a lifter such as a crane to remove heavy parts (20 kg [45 lbs] or more) from the machine. (7) Use proper tools, and replace or repair defective tools. (8) Support the machine and attachment with supports or blocks if the work is performed in the lifted condi- tion. (3) Inspecting machines Identify the parts to be disassembled before start- ing work, determine the disassembling procedure by yourself considering the workshop situations etc., and request procurement of necessary parts in advance. 1.1.3 DISASSEMBLING AND ASSEMBLING HY- DRAULIC EQUIPMENT (4) Recording Record the following items for communication and prevention of recurring malfunction. (1) Removing hydraulic equipment 1) Before disconnecting pipes, release the hy- draulic pressure of the system, or open the re- turn side cover and take out the filter. 1) Inspection date and place. 2) Model name, applicable machine number, and hour meter read. 2) Carefully drain oil of the removed pipes into a containers without spilling on the floor. 3) Trouble condition, place and cause. 3) Apply plugs or caps on the pipe ends to avoid oil spillage and dust intrusion. 4) Visible oil leakage, water leakage and damage. 5) Clogging of filters, oil level, oil quality, oil con- tamination and loosening of connections. 4) Clean off the external surface of the equipment before disassembling, and drain hydraulic and gear oil before placing it on the workbench. 6) Result of consideration if any problem exists based on the operation rate per month calculat- ed from hour meter indication after the last in- spection date. (2) Disassembling hydraulic equipment 1) Do not disassemble, reassemble or modify the hydraulic equipment without the permission of the manufacturer, who is not responsible for the performance and function of the product after modification. (5) Arrangement and cleaning in service shop 1) Tools required for repair work. 2) Prepare space to place the disassembled parts. 3) Prepare oil containers for draining oil etc. 2) When disassembling and reassembling for un- avoidable reason, refer the work to qualified personnel who have the specific knowledge or completed the parts service training. 1.1.2 SAFETY IN DISASSEMBLING AND AS- SEMBLING 3) Provide matching marks to facilitate reassem- bling work. (1) Wear appropriate clothes with long sleeves, safety shoes, safety helmet and protective glasses. 4) Before starting the work, read the manual of disassembling procedure, if it is provided, and decide whether the work can be performed by yourself. 1-3

  6. 1. OUTLINE 5) Use the special jig and tools without fail if they are specified. SWARNING Operation of the hydraulic equipment with- out filling hydraulic oil or lubricant or with- out performing air bleeding will result in damage to the equipment. 6) If it is hard to remove a part according to the procedure, do not try it by force but investigate the cause. 7) Place the removed parts in order and attach tags to facilitate the reassembling. 3) Perform air bleeding of the hydraulic pump and slewing motor after loosening the upper drain plug, starting the engine and keep it in low idle condition. Complete the air bleeding when seeping of hy- draulic oil is recognized, and tightly plug. 8) Note the location and quantity of parts com- monly applied to multiple locations. (3) Inspecting parts 1) Ensure that the disassembled parts are free from seizure, interference and uneven contact. 2) Measure and record wear condition of parts and clearance. 4) Perform air bleeding of the travel motor and the hydraulic cylinders by running the engine for more than 5 minutes at low speed without load. 3) If the problem is found in a part, repair or re- place it with a new one. SWARNING Do not allow the hydraulic cylinder to bot- tom on the stroke end just after the mainte- nance. (4) Reassembling hydraulic equipment 1) Turn ON the ventilation fan or open windows to maintain good ventilation prior to starting the cleaning of parts. 2) Perform rough and finish cleaning before as- sembling. 5) Perform air bleeding of pilot line by performing a series of digging, slewing and travel. 3) Remove washing oil by air and apply clean hy- draulic or gear oil for assembling. 6) Check hydraulic oil level after placing the at- tachment to the oil check position, and replen- ish oil if necessary. 4) Always replace the removed O-rings, backup rings and oil seals with new ones by applying grease in advance. 1.1.4 ELECTRICAL EQUIPMENT 5) Remove dirt and moisture from and perform de- greasing on the surface where liquid gasket to be applied. (1) Do not disassemble electrical equipment. 6) Remove rust preventive agent from the new parts before use. (2) Handle it carefully not to drop and give a shock. 7) Fit bearings, bushings and oil seals using spe- cial jigs. (3) Turn the key OFF prior to connecting and discon- necting work. 8) Assemble the parts utilizing matching marks. (4) Disconnect the connector by holding it and press- ing the lock. Do not pull the wire to apply force to the caulking portion. 9) Ensure all the parts are completely assembled after the work. (5) Connect the connector and ensure it is completely locked. (5) Installing hydraulic equipment 1) Ensure hydraulic oil and lubricant are properly supplied. (6) Turn the key OFF prior to touching the terminal of starter or generator. 2) Perform air bleeding when: (7) Remove the ground (earth) terminal of battery when handling tools around the battery or its relay. 1. Hydraulic oil changed 2. Parts of suction side piping replaced (8) Do not splash water on the electrical equipment and connectors during machine washing. 3. Hydraulic pump installed 4.

  7. 1. OUTLINE If moisture adhesion is found, dry it completely be- fore the connection. 1.1.6 WELDING REPAIR (1) Refer repair welding to qualified personnel accord- ing to the appropriate procedure. SWARNING Battery electrolyte is hazardous. Battery electrolyte is dilute sulfuric acid. Exposure of skin or eyes to this liquid will cause burning or loss of eyesight. If the exposure occurs, take the following emergen- cy measures and seek the advice of a medical spe- cialist. (2) Disconnect the ground (earth) cable of the battery before starting the repair. Failure to do so will cause damage to the electrical equipment. (3) Move away the articles in advance that may cause fire if exposed to sparks. (4) Before starting the repair of the attachment, do not fail to cover the plated surface of the piston rod with flameproof sheet to prevent it from being exposed to sparks. • When skin exposed: Wash with water and soap sufficiently. • When eyes exposed: Immediately wash away with city water continu- ously for more than 10 minutes. 1.1.7 ENVIRONMENTAL MEASURE (1) Run the engine at the place that is sufficiently ven- tilated. • When a large amount of the liquid flows out: Neutralize with sodium bicarbonate or wash away with city water. (2) Industrial waste disposal Dispose of the following parts according to the rel- evant regulations: Waste oil and waste container Battery • When swallowed: Drink a large amount of milk or water. • When clothes exposed: Immediately undress and wash. (3) Precautions for handling hydraulic oil Exposure of eyes to hydraulic oil will cause inflam- mation. Wear protective glasses before handling to avoid an accident. If an eye is exposed to the oil, take the following emergency measures: 1.1.5 HYDRAULIC PARTS • When an eye exposed: Immediately wash away with city water suffi- ciently till stimulative feeling vanishes. (1) O-ring • Ensure O-rings have elasticity and are not dam- aged before use. • When swallowed: Do not let vomit, and receive medical treatment immediately. • Use the appropriate O-rings. O-rings are made of various kinds of materials having different hardness to apply to a variety of parts, such as the part for moving or fixed portion, subjected to high pressure, and exposed to corrosive fluid, even if the size is same. • When skin exposed: Wash with water and soap sufficiently. (4) Others Use replacement parts and lubricants authorized as the genuine parts. • Fit the O-rings without distortion and bend. • Always handle floating seals as a pair. (2) Flexible hose (F hose) • Use the appropriate parts. Different parts are used depending on the working pressure even the size of fitting and the total length of the hose is same. • Tighten the fitting at the specified torque. Ensure no kink, tension, interference nor oil leakage is recognized. 1-5
