The proper and safe lubrication and maintenance for this machine, recommended by Manufacturer, are outlined in the OPERATOR’S MANUAL for the machine. Improper performance of lubrication or maintenance procedures are dangerous and could result in injury or death. Read and understand the MANUAL before performing any lubrication or maintenance.

Do not operate this machine unless you have read and understand the instructions in the OPERATOR’S MANUAL. Improper machine operation is dangerous and could result in injury or death. (6) Relieve all pressure in air, oil or water systems before any lines, fittings or related items are disconnected or removed. Always make sure all raised components are blocked correctly and be alert for possible pressure when disconnecting any device from a system that utilizes pressure.

The serviceman or mechanic may be unfamiliar with many of the systems on this machine. This makes it important to use caution when performing service work. A knowledge of the system and or components is important before the removal or disassembly of any component.

(7) Lower the bucket, dozer, or other attachments to the ground before performing any work on the machine. If this cannot be done, make sure the bucket, dozer, ripper or other attachment is blocked correctly to prevent it from dropping unexpectedly.

Because of the size of some of the machine components, the serviceman or mechanic should check the weights noted in this manual. Use proper lifting procedures when removing any components. Weight of components table is shown in the section ; SPECIFICATIONS.

(8) Use steps and grab handles when mounting or dismounting a machine. Clean any mud or debris from steps, walkways or work platforms before using. Always face to the machine when using steps, ladders and walkways. When it is not possible to use the designed access system, provide ladders, scaffolds, or work platforms to perform safe repair operations.

The following is a list of basic precautions that must always be observed. (1) Read and understand all Warning plates and decal on the machine before Operating, Maintaining or Repairing this machine.

(9) To avoid back injury, use a hoist when lifting components which weigh 20kg (45lbs) or more. Make sure all chains, hooks, slings, etc., are in good condition and are the correct capacity. Be sure hooks are positioned correctly. Lifting eyes are not to be side loaded during a lifting operation.

(2) Always wear protective glasses and protective shoes when working around machines. In particular, wear protective glasses when using hammers, punches or drifts on any part of the machine or attachments. Use welders gloves, hood/goggles, apron and the protective clothing appropriate to the welding job being performed. Do not wear loose fitting or torn clothing. Remove all rings from fingers, loose jewelry, confine long hair and loose clothing before working on this machinery.

(10)To avoid burns, be alert for hot parts on machines which have just been stopped and hot fluids in lines, tubes and compartments. (11)Be careful when removing cover plates. Gradually back off the last two capscrews or nuts located at opposite ends of the cover or device and carefully pry cover loose to relieve any spring or other pressure, before removing the last two capscrews or nuts completely.

(3) Disconnect the battery and hang a "Do Not Operate" tag in the Operators Compartment. Remove ignition keys. (4) If possible, make all repairs with the machine parked on a firm level surface. Block the machine so it does not roll while working on or under the machine. Hang a "Do Not Operate" tag in the Operators Compartment.

(12)Be careful when removing filler caps, breathers and plugs on the machine. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure. The danger is even greater if the machine has just been stopped because fluids can be hot.

(5) Do not work on any machine that is supported only by lift, jacks or a hoist. Always use blocks or jack

0-3


(21)Do not operate a machine if any rotating part is damaged or contacts any other part during operation. Any high speed rotating component that has been damaged or altered should be checked for balance before reusing.

(13)Always use the proper tools that are in good condition and that are suited for the job at hand. Be sure you understand how to use them before performing any service work. (14)Reinstall all fasteners with the same part number. Do not use a lesser quality fastener if replacements are necessary.

(22)Be careful when servicing or separating the tracks (crawlers). Chips can fly when removing or installing a track (crawlers) pin. Wear safety glasses and long sleeve protective clothing. Tracks (crawlers) can unroll very quickly when separated. Keep away from front and rear of machine. The machine can move unexpectedly when both tracks (crawlers) are disengaged from the sprockets. Block the machine to prevent it from moving.

(15)Repairs which require welding should be performed only with the benefit of the appropriate reference information and by personnel adequately trained and knowledgeable in welding procedures. Determine type of metal being welded and select correct welding procedure and electrodes, rods or wire to provide a weld metal strength equivalent at least to that of the parent metal. Make sure to disconnect battery before any welding procedures are attempted. (16)Do not damage wiring during removal operations. Reinstall the wiring so it is not damaged nor will be damaged in operation of the machine by contacting sharp corners, or by rubbing against some object or hot surface. Do not connect wiring to a line containing fluid. (17)Be sure all protective devices including guards and shields are properly installed and functioning correctly before starting a repair. If a guard or shield must be removed to perform the repair work, use extra caution and replace the guard or shield after repair is completed. (18)The maintenance and repair work while holding the bucket raised is dangerous due to the possibility of a falling attachment. Don’t fail to lower the attachment and place the bucket to the ground before starting the work. (19)Loose or damaged fuel, lubricant and hydraulic lines, tubes and hoses can cause fires. Do not bend or strike high pressure lines or install ones which have been bent or damaged. Inspect lines, tubes and hoses carefully. Do not check for leaks with your hands. Very small (pinhole) leaks can result in a high velocity oil stream that will be invisible close to the hose. This oil can penetrate the skin and cause personal injury. Use card-board or paper to locate pinhole leaks. (20)Tighten connections to the correct torque. Make sure that all heat shields, clamps and guards are installed correctly to avoid excessive heat, vibration or rubbing against other parts during operation. Shields that protect against oil spray onto hot exhaust components in event of a line, tube or seal failure must be installed correctly.

TRANSPORTATION

(1) LOADING MACHINE ON A TRAILER 1. Keep trailer bed clean. Put chocks against truck wheels. 2. Use a ramp or loading deck. Ramps must be strong enough, have a low angle, and correct height. Load and unload machine on a level surface. 3. Travel machine onto ramps slowly. Center the machine over the trailer. 4. Lower all attachment. 5. Stop engine. Remove key from switch.

Do not put chains over or against hydraulic lines or hoses. 6. Fasten machine to trailer with chains or cables. During transportation, the bucket or attachments may hit the canopy or the cab. Therefore, set the machine in the transporting position by observing following points: a. Extend the bucket cylinder fully. b. Extend the arm cylinder fully. c. Lower the boom. d. If machine cannot be transported with arm cylinder fully extended, remove bucket or attachment and extend arm cylinder. (2) TRANSPORTATION DIMENSION AND WEIGHT OF ATTACHMENT 1.

TORQUE SPECIFICATIONS FOR CAPSCREWS & NUTS

The following Torque Specifications are provided for use when actual torque value of a fastener is not known. Check the capscrews and nuts for their looseness and dropping off before the start of daily work and at the periodical maintenance. Retighten the loosened ones, and install new ones for the dropped off. For the new machine, the check and retightening of them must be carried out at first 50 hours operation. For the replacement of them, make sure to use the same size of manufacturer's genuine parts. Refer to the table below for the tightening and retightening of capscrews. • The table below is not applicable for the capscrews to fix the cover, etc., made of plastic. For the tightening torque for such capscrews, consult with an authorized our distributor. Over-tightening may cause damages on the parts to be fixed. • In case that the tightening torque is specified in the manual, use such torque values regardless to the table below. • Numerical indication on the capscrew head shows the classification for strength (e.g., 7 = 7 T). No indication is provided for smaller size of capscrews, M 5 or less. Make certain to tighten all capscrews and nuts to proper torque values.

13. MAINTENANCE STANDARD AND TEST PROCEDURE

13.1

HOW TO USE MAINTENANCE STANDARDS AND PRECAUTIONS

(1) Application 1. For New Machine; This manual is to be used to compare actual performance and functions of the machine with performance standards. 2. At Specific Self-Inspection (as per LOCAL RULES); The maintenance standards are criteria to determine time needed for reconditioning, adjustment and replacement. 3. At Deterioration of Performance; This manual provides the criteria for safe and economical judgment on whether the deterioriation of performance on the machine is caused by a fault or normal 4. For Replacement of Major Components; This manual is the standard to determine the time for replacement to maintain the performance of major components such as pump, etc (2) Terminology 1. Standard Values : These are the standard values to assemble and regulate a new machine. Where special notes are not given, these values are based on the machine with standard structure (machine with standard attachments and shoes). 2. Standard Values for Repair : These are of the values at which the reconditioning is required. In order to ensure the performance and safety, it is strictly prohibited to use the machine with the parts and components over the standard values. 3. Serviceability Limit : This is of the service limit for each part and component at which reconditioning is impossible and the part must be replaced with a new one. All the parts and components which are estimated to exceed the serviceability limit up to the next periodic inspection and maintenance, should be also be replaced. Operating the machine with parts and components that have exceeded the serviceability limit is unsafe and could result in equipment failuer and down time. (3) Precautions for Judgment : 1. Evaluation for Measured Data : Some variation on the measured data is inevitable, due to differences between old and new versions of the machine and measurement conditions. Measured data should be judged comprehensively, taking into consideration the level and extent of measurement, rather than merely compared with standard values. 2. Determination for Reconditioning, Adjustment or Replacement : There are two kinds of deterioration of machine performance; one is due to normal wear over time, and the other is recoverable to the standard values with the adjustment for presssure, etc. Therefore, the determination for reconditioning, adjustment or replacement should be conducted taking various factors into consideration such as operating hours, working conditions and maintenance conditions of the machine, so that the machine is able to be operated at the optimum performance level.

13. MAINTENANCE STANDARD AND TEST PROCEDURE (4) Other Precautions 1. Parts with Aging Effect : The rubber products such as hydraulic hoses, O-rings, oil seals, etc. will deteriorate with age. It is necessary to replace them to new ones at periodic intervals or at every overhaul. 2. Parts required Periodical Replacement : It is recommended to designate the important hoses critical for safety as Very Important Parts (V.I.P.), and periodically replace them with new ones. 3. Inspection & Replacement of Lubricants : The machine operator should become familiar with the procedures and precautions for safe handling and maintenance of the machine, including procedures for inspection and lubrication. Refer to the OPERATOR'S MANUAL.

MEASURING ENGINE SPEED

13.3.1 ENGINE SPEED MEASUREMENT (1) Measuring Instruments 1. Diesel Speedometer (Measuring engine speed by means of applying a pick-up to one of injection pipes) 2. Surface Thermometer (Measuring the surface temperature getting contact of the probe with the surface of hydraulic oil tank and radiator)

Engine Speed measurement (The above figure shows concept) (2) Engine Warming up Operation Start up the engine, and make the coolant temperature within the range of 60 to 90C degrees (140 to 194F degrees). Check the coolant temperature with the coolant thermometer on the monitor panel. The white color zone shows approx. 67 to 105°C (153 to 221°F degrees) of temperature range. Therefore, when the indicator is located at around center of the white zone, it is suitable for the engine operation. (3) Engine Speed Measurement 1. Apply the pick up of speedometer to one of convenient injection pipes. (Refer to Fig. "Engine Speed measurement") 2. Measure the engine speed at idling with no load, and compare it to the figure in the STANDARD VALUE TABLE.

13. MAINTENANCE STANDARD AND TEST PROCEDURE (4) Speed Adjustment 1. Low / High Idling Speed is low ; The proper engine speed is obtained with the length of accelerator wire as shown in the right sketch. When the engine speed is lower than the standard speed, adjust the length of wire with loosening the capscrew (9) of throttle lever side.

13. MAINTENANCE STANDARD AND TEST PROCEDURE (2) Pressure Measuring Procedures 1. After releasing pressure in the hydraulic oil tank, and setting a 49 MPa (7100 psi) pressure gauge to either of pressure detecting ports (G1, G2 or G3, PF1/4 with plug), operate the circuit to be measured to measure the relief pressure. 2. When the main relief pressure is being within the standard range, the measurement for the overload relief pressure may be omitted. 3. If the main relief pressure is lower than the standard range, tighten up the main relief valve by half turn [pressure increase by 12.2 MPa (1770 psi)], then measure the pressure at overload relief valve. 4. After adjustment for the overload relief pressure, return back the main relief pressure within the standard range.
