For Safe Driving IMPORTANT: Remove the protective (rust preventative) aluminum cover wrapped around the cylinder rods immediately after receiving the machine. If the machine is left with the covers on, water can collect on the inside of the cover, which will be the cause for rust to develop on the cylinder rod.

In the case of transportation by sea, sea water salt adheres to the machine making rust easier to develop. Immediately follow the measures below after receiving a machine that has been transported by sea. If the measures are not taken, the machine will develop rust easily.

1. Confirm that there are no salt deposits on the machine exterior. When salt deposits are suspected, wash the entire machine with water.

3. If Storage Is To Be Continued [Storage procedures for rust prevention.]

1 Grease up each part of the attachment.

CAUTION Do not use high pressure cleaning water directly on the alternator, battery and other electrical parts or wiring.

Explanation of device 3. Check the battery regularly.

WARNING

a) When you use the battery which requires added solution, check the solution level and always fill it up if the level is low. b) Check the terminals and fixtures. c) Checking voltage using a tester is also recommended.

When using or charging the battery which requires added solution at the electrolyte level below the “LOWER Level” indicated at the side of battery, it may cause damage (exposition) to the battery.

IMPORTANT

The battery which requires added solution

If the battery which requires added solution is continued to be used with the electrolyte level below the “LOWER Level” indicated at the side of battery, it may deteriorate the battery quicker.

1. The battery requires added solution.

However it is unnecessary to add solution at the new machine because it equips it with the maintenance free battery.

After being used for a given period, the solution inside the battery (dilute sulfuric acid) will decrease.

If the solution level is close to the LOWER level, add distilled water or regular battery solution up to the UPPER level. (if the label indication is not attached, verify it by using an indicator)

The solution level is too low and the polar plates are exposed.

The filled hydrogen gas gets short circuited

Explosion!

Electrolyte level is low

1-0038E

Do not add the solution above the UPPER level line.

1-0037E

2. Explosion Accident Example a) If the battery which requires added solution is left with the solution level low, hydrogen gas tends to be generated and fill the inside of the battery. b) If the cells are exposed and deteriorated, the plus (+) polar plate and negative (-) polar plate easily get short-circuited. c) When the sparks caused by the short circuit ignite the inner gas, the battery may explode.

Characteristics of Hydraulic Excavator

1. Listen for unusual noise from the engine, hydraulic equipment, reduction gear, travel unit and front attachment area. a) Creaking from any parts b) Wearing noise c) Vibration noise d) Striking noise at constant intervals e) Irregular noise of hydraulic devices

The following are characteristics of the machine excavator and not problems. ● When the arm or bucket is operated in the air, it may stop suddenly. This is because the pump discharge can not keep up with the movement of the cylinder caused by the attachment weight. ● During swing or travel, or when starting or stopping, some sound may be heard in the hydraulic circuit. This sound comes from the brake valve. ● The reason the swing does not stop immediately after returning the swing lever to neutral is that the machine is being protected from shock and operator fatigue is being reduced. ● When lowering the boom, the sound heard is that of the oil flowing inside the valve.

2. If the H lights on the hydraulic oil and water thermometer gauge light up, slow down the engine speed and stop operations for the unit to cool.

Check coolant water and radiator.

3. If water or oil leakage is found or any problem with the meters, monitor or operation levers is found, stop and check and make repairs.

WARNING If an abnormality is detected in the machine, immediately stop the operation.

When you find something is wrong with the machine while operating, immediately stop the operation, check and repair the problem.

Digging Operations

Dumping

For digging work, position the bucket at the target spot with the boom and arm and use the arm for digging.

Operate the bucket so that it scoops up the dirt as fast as possible.

Digging is done mainly with the arm.

The arm is most efficiently used for digging in the range from 90° forward to 30-45° toward the cab.

For digging, align the bucket teeth in the digging direction and run the bucket at full stroke.

After digging, raise the boom and when swinging is necessary, swing after the boom is raised. Just before returning the swing lever into neutral, raise the arm. Half of the time required for dumping is used in swinging.

Work can be done most efficiently if the swing angle is kept at a minimum, depending on the terrain.

2-0052

2-0050

When dumping dirt into a truck, do not dump the load from a position which is higher than necessary.

Position the truck at such a position that the swing angle and reach are minimized for dumping.

Position the machine lengthwise with the truck and load dirt from the front of the truck. Such operations can speed up the work.

When dumping, make sure that the load is evenly spread to prevent excess burden on the truck’s rear tires.

When the dirt does not fall easily, move the bucket lever 2-3 times to dump the dirt.

(Do not use the shock of the bucket end to dump the dirt.)

Operating Instructions (Operating Procedures).

For trenching, align the machine travelling direction with that of the trench, and gradually travel the machine backward as digging progresses.

When levelling toward the machine, slowly pull the arm toward the machine and slightly raise the boom.

If the arm passes the vertical position, slowly lower the boom and maneuver so the bucket can move horizontally.

Bucket movement can also be added.

Shovel operation procedures (when the bucket is reversed) differ from that for back hoe digging.

Because the bucket is reversed, bucket operations are opposite.

Digging is done mainly with the arm cylinder.

Be careful of interference with the cab.

Digging power is slightly reduced compared to back hoe digging.

Operating in Cold Climates Anti-freeze mixing

When the temperature drops, the engine may become hard to start or the coolant may freeze. Take the following precautions in cold weather.

Anti-freeze is used to prevent the engine coolant from freezing during the winter or in cold areas. Mix it with water according to the lowest expected temperature.

Fuel and lubricants

Anti-freeze Mixing Ratio

Replace the lubricants for each device with that of lower viscosity. For the designated viscosity, refer to the section on “Fuel and Lubricants According to Ambient Temperature.”

As for fuel, use fuel with fluid point of 41°F (5°C) lower than the ambient temperature.

ࠑ F Lower Temp.(͠) Mixing Ratio (%)

Anti-freeze mixing ratio The machine has long-life coolant (LBX Company LLC genuine coolant - Clean Coolant) when it is shipped from the factory.

When the temperature is below 14°F (-10°C), refer to the anti-freeze mixture percentage chart and adjust the concentration.

WARNING Battery produces flammable gases, always keep flames away.

The battery liquid is dangerous. Prevent it from getting into the eyes or on the skin. If you spill it on your skin or get it into your eyes, wash it off with lots of water and see a doctor for treatment.

● It is recommended that the mixture ratio be controlled by coolant concentration gauge.

CAUTION When the temperature lowers, the battery charge also lowers. If the battery charging rate is low, the battery solution may freeze.

Keep the charging rate close to 100% to prevent freezing.

Use of anti-freeze ● The concentration of the anti-freeze should be in the range of 30-60%. If the concentration is weak, the rust-proof performance is adversely affected. ● When water is reduced naturally, fill with 50% diluted water. ● Use always coolant with ASTM D3306 or equivalent, and do not mix with other kinds. ● Anti-freeze is flammable. Do not have open flames near it. ● Always use soft water for coolant.

The maintenance free battery ● Check the hydrometer of battery. (Refer to the section “Maintenance”)

The battery which requires added solution ● Measure the specific gravity and calculate the charging rate using the table below.

Fuel WARNING ● Sufficient care is necessary during inspection and maintenance. ● Be especially careful about fire. (Do not smoke while working.) ● Wipe off any diesel fuel that is spilled during refilling, inspection or maintenance, because it may cause a fire.

● Fuel leaking from the fuel hose, injection pump, fuel filter or joint may result in a fire. If any fuel leakage is found, repair the area immediately. ● Do not use any substitute fuel because it may cause poor performance or even a fire.

Engine fuel and maintenance of fuel filters

2. Applicable standards for diesel fuel

In order to meet the emission control regulation of 3rd-stage, the engine components have been made precisely and they are to be used under high-pressure conditions. Therefore, the specified fuel must be used for the engine.

As a matter of course, not only the guarantee will not be given for the use of a fuel other than the specified but also it may invite a serious breakdown. In addition, since suitable specifications for the fuel filter elements have been established for this engine, use of the genuine filter is essential. The following describes the specifications and the requirements of the fuel to be applied, and maintenance of the fuel and the fuel elements.

Recommendation

ASTM (AMERICAN SOCIETY TESTING AND MATERIALS)

D 975

JIS (JAPANESE INDUSTRIAL STANDARD)

NO.2

DIN (DEUTSCHE INDUSTRIE NORMEN)

DIN 51601

SAE (SOCIETY OF AUTOMOTIVE ENGINEERS) Based on SAE-J-313C

NO.2-D

BS (BRITISH STANDARD) Based on BS/2869-197

Class A-1

If a standard applied to the fuel for the diesel engine is stipulated in your country, check the standard for details.

3. Requirements for diesel fuel Although conditions required for the diesel fuel are illustrated above, there are other requirements exerting a big influence on its service durability and service life.

Be sure to observe the following requirements for selecting fuel.

Fuel to be applied 1. Selection of fuel Following conditions must be met for the diesel engines, that is the one; (1) In which no dust even fine one is mixed, (2) With proper viscosity, (3) With high cetane rating, (4) With good flow properties in lower temperature, (5) With not much sulfur content, and (6) With less content of carbon residue.

E1330

Applicable Standard

Sulfur content

2500 ppm or less

HFRR*

460 μm or less

Water content

0.05 wt% or less

* HFRR (High-Frequency Reciprocating Rig.): An index showing lubricating properties of the fuel.

Sulfur content reacts to moisture to change into sulfuric acid after combustion. Use of a fuel containing much sulfur content allows it to accelerate internal corrosion and wear. In addition, much sulfur content quickens deterioration of engine oil allowing its cleaning dispersive property to be worse which results in acceleration of wear of sliding portions.

HFRR is an index that indicates lubricating property of a fuel. Large value of the index means poor lubrication so that seizure of the machine components may result if such a fuel is used.

3-15

Maintenance

Fuel System 2. Two kinds of fuel filter, the pre-filter and the main filter, are mounted on the machine.

Be sure to use the genuine fuel filters and replace them at a periodic intervals.

Since a fuel with high HFRR value also has lower viscosity, it can easily be leaked out. If the fuel is mixed with the engine oil, the oil is diluted to deteriorate its lubricating property resulting in acceleration of wear. Water content allows inside of the fuel tank to rust which in turn blocking the fuel line and the fuel filter. This may also cause wear and seizure of the machine components. If atmospheric temperature goes below the freezing point, moisture content in the fuel forms fine particle of ice allowing the fuel line to be clogged. Obtain table of analysis for the fuel you are using from the fuel supplier to confirm that it meets the criteria described above.

Replacement criteria Every 250 hour of use Every 500 hour of use Pre-filter Main filter

○ ○

Since the pre-filter and main filter also has a function of water separation, discharge water and sediment when the float reaches lower part of the filter elements.

3. Time to replace filters may be advanced according to properties of the fuel being supplied.

Running the engine with the fuel filter blocked may cause the engine to be stopped due to establishment of engine error code.

If much foreign objects are found in the fuel, carry out earlier inspection and regular replacement of the filters.

IMPORTANT If a fuel which does not meet the specifications and the requirements for the diesel engine, function and performance of the engine will not be delivered. In addition, never use such a fuel because a breakdown of the engine or an accident may be invited.

Guarantee will not be given to a breakdown caused by the use of a improper fuel. Some fuels are used with engine oil or additives mixed together with diesel engine fuel. In this case, do not use these fuels because damage to the engine may result as the fuel has been contaminated. It is natural that the emission control regulation of 3rd-stage will not be cleared in case where a fuel that does not meet the specifications and the requirements is used. Use the specified fuel for compliance of the exhaust gas control.

4. If dust or water get mixed with the fuel, It may cause the engine trouble and an accident.

Therefore, take measures to prevent dust and/ or water from being entered in the fuel tank when supplying fuel.

When supplying fuel directly from a fuel drum can, leave the drum as it stands for a long period of time to supply clean fuel standing above a precipitate.

If it is hard to leave the drum for a long period of time, install a fuel strainer and a water separator before the fuel tank of the machine to supply clean fuel.

Maintenance of fuel filters 1. Be sure to use the genuine fuel filters.

The fuel injection system is precisely constructed and the genuine filter employs finer mesh than conventional filters to improve protection of machine equipment.

If a filter with coarse mesh is used, foreign object passing through the filter enters into the engine so that machine equipment can wear out in a short period of time.

5. Water drain cock is provided on the bottom side of the fuel tank.

Drain water before starting the engine every morning.

In addition, remove the cover under the tank once a year to clean up inside of the tank.

6. Do not pour a moisuture elimination agent (water draining agent) available on the market into the fuel tank.

Pouring it in the tank may cause the engine to be damaged.

IMPORTANT If a fuel filter other than the genuine filter is used, guarantee will not be applied to a fault caused by the use of a wrong filter.

Adjusting Method a) Loosen the hexagonal socket head bolt 1 to remove the plate 2. b) Remove the shim plates 3 (as required) the amount corresponding to the backlash amount of the joining area (wear amount). c) Install the plate 2 and tighten the hexagonal head socket bolt 1. d) As the hexagonal socket bolt 1 is tightened, the plate 2 will be pressed against the steel bushing to reduce the clearance.

Clearance amount of about 0.05 in (1.2 mm) is preferable.

7. Apply grease as necessary.

WARNING Stop the engine before adjusting the bucket backlash.

Bucket Backlash Adjustment The machine is provided with a bucket adjustment mechanism which eliminates the backlash of the bucket-to-arm joining area caused by wear.

Due to this mechanism, the sealing condition of the O-rings is kept stable and the wear is delayed. The service life of the bushings and pins thereby increases.

IMPORTANT Too small amount of clearance may cause scuffing or seizure. Always check the clearance.

Cleaning fresh air intake filter Cleaning interval: every weeks

Inspecting the air conditioner before use will lengthen its service life and function.

1. Open the house door at the rear of the operator's cab to open the filter cover 3 of the cab.

2. Handling during off-season Whether it is summer or winter, leave the air conditioner installed because it has refrigerant inside it.

2. Remove the fresh air intake filter 2 to clean it.

3. After cleaning, attach the filter and close the filter cover 3.

IMPORTANT Leave the compressor drive belt as it is regardless of the season.

3. When not using for a long time Operate the air conditioner 1-2 times every 2-3 weeks.

This care prevents oil loss in the components and helps improve the compressor's service life and performance.

Routine Inspection Chart To enjoy lasting and comfortable use of the air conditioner, it is necessary to inspect it routinely. It leads to unnecessarily expensive repair costs to repair the air conditioner after problems occur.

It is highly recommended that preventive maintenance is carried out according to the chart below.

If the air conditioner should break down, turn the switch to OFF and ask for necessary repair.

WARNING ● The air conditioner circuit is filled with high pressure gas and if the lines or compressor parts are loosened, gas will spray out, which is very dangerous. ● Special tools and gauges are needed for the refilling or refrigerant and other maintenance. Always have the air conditioner serviced at a properly equipped service shop. Use R134a as a refrigerant (gas).

Inspecting Refrigerant Amount

Inspections and refilling should be conducted in our Service Shop. (Inspection method) Operate the air conditioner, increase the engine speed slightly (1,400-1,600 rpm) and compared with bubbles observed through the sight glass with the chart.

WARNING ● With excess refrigerant, overcharge occurs and cooling is deficient. Also, the pressure inside the circuit becomes abnormally high and is dangerous. Operate the system with proper level of refrigerant. ● Operating the air conditioner with no refrigerant (gas) adversely affects the compressor. ● The indication of the sight glass is a guide.

Depending on the outside air conditions, it is difficult to determine situations based on the sight glass indication. Check highpressure changes while carrying out inspection (a sudden pressure increase occurs when being overcharged).

Importance of Hydraulic oil Control Construction machinery uses a large volume of oil in the hydraulic system for power transmission, equipment lubrication, rust prevention, and sealing.

According to a survey conducted by a pump manufacturer, seventy percent of the cause for the problems in hydraulic equipment was attributable to inadequate hydraulic oil control.

Therefore, proper control of hydraulic oil helps prevent hydraulic equipment problems and greatly improves safety and reliability. Furthermore, it extends the life of hydraulic oil if it is maintained properly.

Inadequate maintenance 10% Mechanical problems 10%

Other 5% Inadequate hydraulic oil control (Incorrect application of hydraulic oil) 70%

(1) Effects of contamination

Overload operation exceeding ratings 5%

Causes of Problems in Hydraulic Equipment

Once inside the hydraulic circuits, contaminants greatly affect the performance and life of hydraulic equipment.

For example, contaminants in a hydraulic pump develop internal wear to cause increased internal leakage and lower discharge.

Table 1. Routes of Infiltration of Contaminants Classification Particle con- Solid taminant particle

Contaminants Sand dust & fiber particles

Infiltration route During assembly and operation

During manuWelding scales, chips burr, molding facture sands, sealing materials, fibers rubber powder

Furthermore, wear particles generated will circulate in hydraulic oil to deteriorate the performance of others equipment.

Contaminants also enter principal sliding sections of the equipment and cause temporary malfunction, scuffing, and sticking, which can lead to major problems.

Nonparticle contaminants

(2) Causes of contamination Contaminants that deteriorate hydraulic oil quality are mainly classified as follows and by the route of contamination as outlined in Table 1.

Tables 2 and 3 outline the size of contaminants and the contaminants in atmosphere.

(3) Contamination control standard indicated by the weight or size and number of solid particle contaminant (hereinafter called “particles”) contained in 100 ml. For construction machinery, National Aerospace Standard (NAS) (counting method) is popularly applied.

Particle contamination of new hydraulic oil is normally approximately NAS, Class 7. As its operating time becomes longer, oil is contaminated by contaminates or contaminants are generated within, to degrade its class.

NOTE: NAS 1638 for particle contamination (counting method) counts the number of particles in 100 ml of sample fluid according to the size and classify them in twelve classes as outlined in Table 4.

Control Standard........ Within NAS Class 10 It is desirable that the class of hydraulic oil be maintained within the above mentioned standard. Oil beyond Class 12 must be replaced.

Particle contamination of hydraulic fluid is normally

Cleaning Operation The purpose of cleaning oil is to remove the contaminants and sludge by filtering hydraulic oil through a cleaning device.

Normally, the hydraulic system of a construction machine is installed with various filters, and if they are maintained properly, most of the contaminants and sludge is exhausted out of the circuits. However, fine particles (approximately 10 micron or smaller) that cannot be collected by the filters continues to circulate through the circuits.

An oil cleaning device is extremely effective for extending the life of hydraulic oil since it can collect fine particles (approx. 5 micron) that passes freely through the filters installed inside the hydraulic system.

2. When using the crusher Read the instruction manual thoroughly for the crusher. Use extreme care and operate the machine safely by avoiding damage to the machine and tipping over.

Otherwise, it may cause the cylinder and/or the shovel body to be damaged.

Do not operate the machine at the stroke end of the cylinder but operate it by taking a margin to some extent.

In case where the arm is brought down with the cylinder put at its stroke end in addition, the arm cylinder may be damaged by the shock.

Operate it so that each cylinder will not come at its stroke end.

Do not use it for anything but its specified purpose Work suitable for the crusher is wrecking work and cracking rocks and boulders.

Do not use crusher to move or load the broken pieces.

Work in front or in back of the track shoes Before starting work, make sure the main body is level and the footing is stable.

Work at the side of the shoe is not safe and can cause tipping over.

Crusher

Operation at the stroke end of the cylinder is prohibited

Prying operation with crusher is prohibited

When breaking a steel frame with the crusher pulling the steel frame to this side using the bucket cylinder may allow the frame to be broken suddenly, by which the cylinder may come to its stroke end.

In this case also, an excessive shock is to be applied.

Check the cylinder stroke while operating the machine so that it will not be brought to its stroke end even if the load is set free.

If prying operation using the crusher is carried out, an excessive force is applied to the crusher itself and to the arm/boom/cylinder by which may invite an accident and may cause damage to the crusher.

Therefore, prying operation with crusher is strictly prohibited.

Cautions when using super-long arm hydraulic shovel

When the arm is brought down, the arm cylinder may be damaged by the shock at its stroke end.

In addition, since an excessive force is to be applied to the arm cylinder when carrying out jacking-up with the cylinder put at its stroke end, do not operate the machine with the arm at its stroke end.

When operating the super-long arm hydraulic shovel with the crusher being installed, there is a risk causing the crawler of hydraulic shovel to be raised or the hydraulic shovel itself to be overturned when the boom is lowered or the arm is extended horizontally because it becomes unstable as a heavier load is shifted toward the top part.

Observe the restriction to the safe working radius for the hydraulic shovel and the allowable weight of load to operate it within a sufficiently safe working radius.

Crusher

No jacking up is allowed If jacking up or turning of the hydraulic shovel with the crusher pushed against the ground is carrying out, not only an excessive force is applied to the crusher, but also unreasonable twist is applied to the arm and to the boom of the hydraulic shovel which in turn may invite a breakdown or an accident.

Therefore, jacking up of the hydraulic shovel is strictly prohibited.

Special Attachment Selector switch for crusher

CAUTION

When using the crusher in the machine equipped with a compatible circuit, selection of the switch allows the open-close cycle of the crusher to be faster so that operation efficiency can be increased.

The 1st and 2nd speed can be selected by the switch illustrated below.

When using the breaker of the machine equipped with both breaker and crusher, be sure to turn OFF the switch illustrated below.

● When attaching hydraulic breaker and crusher, etc., it is necessary to select models which are compatible with the excavator. When selecting special attachments, consult with our dealers or business offices in your area. ● When using special attachments, please read carefully the instructions for the special attachment and operate the machine safely preventing the possible damage to the excavator and the special attachments. ● Since a special attachment is heavier than a standard bucket, do not operate the machine at the stroke end of the hydraulic cylinder. Extended time of operation at the stroke end may cause the boom to be lowered unexpectedly.
