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.

AL

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

TE RN

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.

IN

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)

CO US N F E ID O E F N TS TI M AL GL : F O OR BA T L H Electrolyte level is low

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.

Blade Operation Caution for blade operation

The following are characteristics of the machine excavator and not problems.

Blade is for light duty work such as pushing soft dirt or mud only.

AL

● Do not push down hard on the blade or it may cause damage to the blade and foot.

● To avoid damage to the blade, do not side load

● When the arm or bucket is operated in the air, it

IN

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.

Operating Instructions (Procedures) 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.

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.

For a wide trench, first dig both sides, then dig the center last.

Operating Instructions (Procedures) Shovel Operation

After digging, fill back and level the ground by moving the bucket horizontally back and forth.

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.

To release hydraulic pressure

IN

Self-initiated periodical inspections

1. Lower the attachment to the ground.

You must also have the hydraulic shovel adjusted thoroughly because this optimizes its functionality as well as stretching its life.

E

2. Turn the starter switch to the "OFF" position and stop the engine.

CO US N F E ID O E F N TS TI M AL GL : F O OR BA T L H

3. Turn the starter switch to the "ON" position.

4. Gate lock lever must be released (to the operating position).

Inspection and maintenance schedule

Monitor the hour meter readings in the cab to guide you in keeping the regular service intervals. The recommended intervals are determined under normal working conditions. When you overload your machine, operate in severe weather, or operate under demanding conditions, you need to inspect the machine more frequently. Inspect when your machine has operated for the number of hours recommended for inspection, or the number of months recommended for inspection, whichever comes first.

5. Move the right and left operational levers back and forth, and left to right, for approximately ten times.

6. Turn the starter switch to the "OFF" position.

7. Release the pressure from the hydraulic oil tank.

(To release pressure, push in the tip 1 of breather rubber cap at the top of hydraulic oil tank.)

Ԙ

General cautions when performing inspections

For crucial inspections and maintenance (i.e. adjusting/servicing hydraulic components or electronic components), your machine must go in a service shop.

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.

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

Recommendation

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 Pre-filter

○

Main filter

AL

Every 250 hour of use Every 500 hour of use

TE RN

○

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

CO US N F E ID O E F N TS TI M AL GL : F O OR BA T L H

E

IN

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.

Wide shoes are designed for use in work on the soft ground or flat places.

If a wide shoe is used in the rocky place, the shoe will be deformed or damaged. Do not use wide shoes for work in the rocky or rough surface ground.

Cleaning Crawler • As necessary ● After finishing work on wet surface ground, remove the earth and mud attached between shoe and travel unit (sprocket). If left with earth attached, the earth gets solid and may cause damage to shoe and the travel performance will be affected. ● After finishing work on the beach or other salt covered places, wash off all salt completely. If washing off is not enough, the crawler will get rusty and cause early wearing and operational faults.

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.

Crusher 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.

Optional Components No jacking up is allowed

Crusher Change each valve (stop valve, three way valve) tovalves for use with the crusher

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.

• When transporting the hydraulic shovel (main body), remove the crusher.

• The crusher is heavier than the bucket. To prevent damage to the attachment due to the impacts while transporting, the crusher must be removed.

• When changing the attachments very often, hydraulic oil contamination tends to progress quickly. Carry out regular sampling of the hydraulic oil contamination.

• Be careful of falling objects when working at high places. Attach guards as necessary.

• When carrying out building wreckage work inside the building, check the strength of the floor before starting the operation.
