2 - SAFETY INFORMATION

Vibration levels The vibration level transmitted to the operator depends mainly upon the conditions of the ground on which operations take place, the mode of operation of the machine and its equipment. The exposure to vibrations can be considerably reduced when the following recommendation are complied with: • use equipment compatible with the machine and the type of work do be done; • adjust and lock the seat in the correct position; also inspect regularly the suspensions of the seat, if provided, and perform the adjustments and repairs as required; • perform regularly the current maintenance operations of the machine at the prescribed intervals;

• when travelling, avoid, as far as possible, particularly rough terrain or the impact against possible obstacles.

The exposure is dependant on machine operating techniques and can be controlled by following the instructions described in this manual.

• The weighted average quadratic acceleration value to which the operator’s arms are subjected does not exceed 2.5 m/s².

• The weighted average quadratic acceleration value to which the operator’s body is subjected does not exceed 0.5 m/s². These results were obtained using an acceleration gauge during the excavation works.

• operate the equipment in a uniform manner, preventing, as far as possible, sharp movements or extreme shocks; NOTE: the Whole-Body exposure value is determined under particular operating and terrain conditions and therefore may not be representative for all the possible operating conditions within the intended use of the machine. Consequently this single Whole-Body vibration emission value is not intended to determine the Whole-Body vibration exposure as required by European Directive 2002/44/EC. For this purpose it is recommended to conduct working conditions measurement. If this is not feasible use of information provided in the table below from ISO/TR 25398:2006 (*).

Parking the machine after an emergency stop of engine Avoid emergency stops of the engine as much as possible.

It should be kept in mind that the engine is to be operated for around 5 min with no load, before stopping the engine.

NOTICE: If the engine stops immediately after an high speed operation, the engine temperature increases remarkably. As a consequence, the engine oil is overheated and the joints jam, etc.

Even if the engine is not running, keep the safety lock lever in the LOCKED position.

When an emergency stop is made and there is no time to lower the bucket to the ground, support it with wood wedges (1) to lock the crawlers.

When the emergency stop is activated on a slope, block both crawlers at their lower sides.

While you are waiting to restart the engine and the machine, free the working area from people and possible obstacles. Set limits around the machine, taking the appropriate measures so that nobody penetrates this area.

Travel on flat and firm ground and in straight lines (or large angles) as much as possible. When turning the machine, move forward and backward alternately as much as possible instead of making a sharp turn.

Check the strength of bridges and road shoulders. Reinforce them if necessary.

Make sure to keep a sufficient distance from bridges and electrical power lines. Prior to digging, check existence and location of electrical lines, gas ducts, water pipes or other public utilities installations. If in doubt, contact local authorities and/or the distributing companies (electric power, gas, telephone, water, telecommunications, etc).

Always travel at slow speed.

When travelling, lift the bucket up to 30 - 40 cm (11.8 15.7 in) from the ground in the travelling direction. Do not travel down a slope in reverse run.

When the machine slips, immediately lower the bucket to the ground and operate the brakes.

Never attempt to rotate the upper structure downhill: the machine could tip over. If this operation is unavoidable, create on the slope a flat working area.

Never attempt to travel up or down a slope with a gradeability of 30 ° ( 58 %) or more.

When the engine stops on a slope, immediately lower the bucket to the ground and move all control levers to the NEUTRAL position, then start the engine again.

If it is difficult to climb a slope with the travel motor due to skidding crawlers, etc., the power of the arm can be utilized to pull up the machine with the bucket engaged on the ground.

When the machine is parked on a slope, even for a short time, lower the bucket (1) and the dozer (2) to the ground, return all control levers to the NEUTRAL position, set the safety lever to the LOCK position and block both crawlers by means of wedges (3).

NOTE: When the hydraulic oil is not sufficiently warm, the machine may not be able to develop its full performance.

Before travelling on a steep slope, preheat machine completely.

6 - WORKING OPERATIONS

Machine operation in water/on soft grounds NOTE: The slewing bearing of the upper structure, the pinion of the rotation motor and the rotary control valve should never operate in water or mud.

If the machine is operated in water or mud, the slewing bearing and the other components may wear excessively.

Immediate replacement of grease or overhaul of the slewing bearing, etc. is required.

Where the river bottom is flat and water flow is slow, the machine may be operated in water, provided that water is not higher than the guide plates of the crawlers (1).

When operating under such condition, use the machine carefully and check condition of river bed. Never enter deeper waters.

TUIL12E2B0023AB

On soft ground, the machine body sinks in some cases gradually. Therefore, pay full attention to the machine at all times during operation.

After travelling in sea water, thoroughly wash up the machine to remove salt.

Make sure to lubricate bucket pins and bushing every 4 h if working with materials in wet conditions, supply grease with a grease gun until grease oozes out.

Both crawlers caught in mud When both crawlers get caught in mud and the machine does not move because it skids, provide logs and boards, as described in the previous step and anchor the bucket firmly to the ground so that you can help the machine to come out from mud.

If the machine is unable to travel because the crawlers are stuck in mud, sand or gravel, raise each crawler side alternately by pushing the bucket against the ground and scraping off mud, sand or gravel. Gravel and mud may be cleared off by rotating the raised crawler back and forth.

NOTICE: Operate the machine from operator’s seat only.

Do not allow any person to come near the machine.

Swing control Rotation of the upper structure • When you work on slopes the machine becomes unstable and unbalanced.

• Make sure the rotation area is clear of persons and obstacles before operating the engine.

• Work up and down inclines or slopes, never across.

• Never slew or turn machine around on slopes.

• Operate control levers carefully to prevent sudden movements that may cause the machine to slip or tip over.

• Prepare a level area for the machine to operate.

• Use a flagman to guide the operator.

LELI11E0227AB

The turret swings when the left control lever is moved rightward or leftward. The swinging speed is determined by the stroke of the lever.

• When moving the left control lever leftward, the turret swings leftward.

• When moving the left control lever rightward, the turret swings rightward.

• When returning the left control lever centrally (neutral position) the turret stops moving.

6 - WORKING OPERATIONS

Practices to improve efficiency • Slewing the upper structure on a slope may cause the machine’s overturning. On a slope, it is very dangerous to slew the upper structure downhill with full bucket.

Prepare a level area for the machine to operate safely.

• Make sure the rotation area is clear of persons and obstacles before operating the engine.

NOTE: The optional attachments offer a wider range of application other than the showed ones.

Digging instructions Use mainly the mere arm force for digging. Use the full bucket rotation travel to fill it completely. Setting the bucket too deep will decrease the machine’s efficiency.

Maximum digging force position The attachment will provide maximum digging force when arm and boom are positioned at 90 - 110 ° from each other.

Operate slowly to get maximum digging force.

Bucket teeth direction LELI11E0228AB

Direct bucket teeth parallel to digging direction. The bucket must be used for shallow diggings, so as to reduce the resistance and avoid damaging the teeth.

Operate boom carefully Activate boom operation by moving the control levers carefully. Do not perform sudden starts and stops of the boom as this creates unnecessary stress on the machine and its components.

Clean sand and soil from bucket Place the arm in horizontal position and bring the bucket to the dumping position. If sand and soil do not fall out, move the bucket lever right and left a few times to remove soil stuck to the bucket.

Operating the dozer The dozer is used to push the soil back into an excavated ditch or for ground levelling.

To distribute the earth heaped up on the ground using the dozer, start from the top or from the sides of the heap. If necessary, adjust the height of the dozer by means of the relevant control lever, to prevent overloading the engine.

Offset digging NOTICE: When the slewing range of the boom is wider, pay attention to the conditions of the surrounding area.

By pressing the left and right side of the slewing pedal (1) alternately, the boom (2) slews in left and right direction, thus enabling offset digging in narrow spaces.

By pressing the left side of the slewing pedal, the boom slews leftwards, and by pressing the right side, the boom slews rightwards.

The advantage of this function is that it enables offset digging work as shown in the figure.

Caution while using rubber crawlers Proper usage

Rubber belt

The rubber crawlers offers excellent features which steel crawlers do not possess.

However, if they are used the same way as the steel crawlers, then their advantages cannot be fully exploited.

Operation of the machine varies upon working site and conditions.

Although the rubber crawler offers many advantages thanks to the properties of its material, it also has disadvantages in terms of strength. As a consequence, it is necessary to be familiar with the characteristics of this kind of crawler.

Less vibration Smooth operation Low noise Harmless for paved road Easy handling Resistant Large traction force : Excellent : Good

: Normal

Rubber crawler warranty The warranty does not cover such damages to the rubber crawlers resulting from improper working or if their tension is inaccurate.

Forbidden operations Do not carry out the following operations: Do not travel nor work on following surfaces: gravelmixed land, rugged and solid rock bed, reinforced concrete, steel plate edges.

LELI11E0259AA

LELI11E0260AA

2

Do not operate and/or travel in such places as river beds where there are lots of stones of different sizes. Rocks may get caught into the grooves of the rubber crawlers, thus damaging the crawler or causing it to come off. The life of rubber crawler is shorter, if it skids or rubs against the soil.

6-14

6 - WORKING OPERATIONS

Do not let oil, fuel, solvents, etc., come in contact with rubber shoes. If this happens, wipe off crawlers with a cloth immediately.

Do not enter such hot places as an open-air fire, steel plate left in the open sun.

Do not work in asphalt levelling.

When storing the machine for a long period (more than three months), keep it in a closed room where it will not be exposed to direct sunshine or rain.

When the machine travels only on one side of the crawler, and keeps the other side floating, the crawler may come off of the rollers or get damaged.

Precautions for use Use care of the following when working.

Rubber crawlers slip easily on icy surfaces.

Take the necessary safety precautions.

Avoid making a spin turn on concrete surfaces.

Avoid abrupt changes of direction as this will cause an early wear or damage of the rubber crawlers.

6-15

6 - WORKING OPERATIONS

Use care so that the bucket does not damage the rubber crawler while working.

Do not move the machine pressing the bucket against a concrete surface or walls.

Lower the machine slowly, if it had previously been lifted by means of the attachment.

If the machine is operated in salty corrosive places, the core metal can detach easily. Do not use the rubber crawler under such circumstances. If the rubber crawlers come in contact with these substances wash them with water.

The rubber crawlers have to be used with a temperature range between -25 °C (-13 °F) and +55 °C (131 °F).

NOTE: Use the rubber crawlers under proper tension, to prevent them from coming off the rollers. Operate the rubber crawler carefully even when tensioning is proper.

Avoid changing direction of the machine on places with different level (about 20 cm (7.87 in)). To overcome the gap, place the machine perpendicular to the obstacle.

When climbing on a slope in reverse, avoid changing the machine direction while climbing between the level ground and the slope.

Machine operation in adverse weather conditions Operation in extreme cold

low dirt and debris to accumulate in the radiator fins, oil cooler fins or debris screen.

• Follow procedures on page (Starting the engine in cold conditions) as starting engine may be difficult due to extremely cold temperatures.

• Use an engine oil, hydraulic oil and diesel fuel designed for use in cold climates.

• Keep batteries fully charged.

• During the engine WARM-UP phase do not increase the engine rpm to prevent premature wear or damage to pumps, motors and other components.

NOTICE: in extremely frigid climates, covering the radiator is a method to aid the machine warm-up. If necessary to maintain operating temperatures, cover the outer edges of the radiator, leaving an opening in the center part of the cover - thus avoiding fan overloading. Keep a close watch on the instrument cluster for warning icons during operation. It may be necessary to use a coolant heater, fuel heater, engine heater jacket, and/or additional battery power to aid engine starting.

• Keep batteries terminals free of ice and snow. Ice and snow could cause the terminals to short circuit and cause extensive damage to the machine systems.

Check the batteries electrolyte (acid) level frequently and fill as necessary with distilled water. If the machine will be left outside overnight, it is recommended to remove the batteries and store in a warm area.

• Make certain that the engine coolant mixture is sufficient to keep the machine safe. Take into consideration wind chill factors when mixing coolant ratios.

NOTICE: mix coolant to a protection temperature of 5 °C lower than the machine will experience during operation, storage or transport.

Mud and water adhering to the machine may freeze interfering with proper machine operation. Use the following general guidelines as reference to prevent malfunctions:

• Keep all belts properly tensioned.

• Make certain that the engine coolant mixture is sufficient to keep the machine safe.

• If the machine becomes overheated, idle the machine to help cool the engine, turn the engine off and check coolant level. After filling to proper level the machine continues to over heat, stop engine, allow to cool, drain and flush entire cooling system and refill with the proper mixture of fresh, clean coolant.

• Check the batteries electrolyte (acid) level frequently and fill as necessary with distilled water.

• Keep a close watch on the instrument cluster for warning icons during operation. Avoid unnecessary low speed running of the engine during operation. During slow, or no work periods, place throttle control lever to LO position.

Operation in high altitudes • Due to low atmospheric pressure at high altitudes, a decrease in engine power will be experienced. Be aware of this fact when placing machine under heavy load in high altitude climates.

• Keep close watch on the coolant temperature meter to avoid overheating of the engine.

Operation in sandy and dusty areas Air filter • Check the engine air filter element frequently in sandy or dusty conditions. Clean or replace the filter element at the corresponding intervals Radiator • Clean the radiator regularly to prevent the radiator core from becoming clogged with dust.

• Remove water and mud from the machine. Remove water adhering to the travel system thoroughly and park on dry ground to prevent the travel system from freezing.

• Retract the hydraulic cylinder rods as much as possible to reduce the exposed areas of the rods. This will prevent mud or water on the rod faces from damaging the seal.

Operation in extreme heat

Fuel • Be careful not to let contamination in the fuel when refuelling. Inspect the elements and filters at the corresponding interval.

Electrical equipment • Clean the starter and generator especially, at the corresponding interval, to prevent dust from accumulating.

Fitting with O-ring The O-ring (2), allows to insulate the oil pressure inside of hose (1) and to avoids oil spillages.

The tightening torque of the joint of each hydraulic hose (1) is determined by the diameter of the hose fitting thread.

If you notice a fault of operation, repair hose connection or replace it.

When connecting worn parts, pay particular attention to keep sealing surfaces clean from dirt and try not to damage them.

O-ring If the fitting is loose and oil leaks may occur, do not tighten it. It is necessary to install a new O-ring and to check again for tightness.

Never install a damaged and deteriorated O-ring even if it is new one. The use of an O-ring other the specified one, causes oil leakage and short life of hydraulic equipment.

Joint Be careful not to damage hoses, pipes or seal faces, this can impair the tightness.

Keep seal surfaces free from dirt.

Fitting with foreign matter inside causes oil leakage.

Hose Avoid high pressure hoses to twist during connection. Life of twisted hoses is drastically reduced.

Wash pipes and hoses, both inside and outside, with washing fluid and accurately dry them before reconnection.

Use of biodegradable oils When you use biodegradable oil, please refer to following: • There are two types of biodegradable oil available: vegetable-based and synthetic-based. We recommend using synthetic oils, because vegetable ones have a maximum operating temperature of 80 °C (176 °F). For this reason, the degradation of vegetable-based oil occurs more rapidly, and they have a reduced service life.

• Do not mix bio-oil with original factory-filled mineral oil; in case it is necessary to use bio-oil, flush the hydraulic system that was filled with bio-oil three times.

• If you use bio-oil, the performance of the rotation brake and that of the parking/travel brake will be reduced, because of the lower friction factor of bio-oil compared to that of mineral oil.

• For further information about the type of biodegradable lubricant and the relevant specifications for use and maintenance, please refer to chapter ACCESSORIES.

Use of coolant • There are two types of coolant depending on the corrosion inhibitors base: ORGANIC-base and INORGANIC base.

• Mini excavators is ORGANIC-base type factory filled.

• Both type can be used, BUT THEY CANNOT BE MIXED. Flush the cooling system before change coolant type.

STORAGE

Precautions when storing the machine for a long period When storing the machine for more than one month, observe the following points to prevent the machine function from deteriorating.

Clean the machine •

Wash the machine thoroughly.

•

Check the travel system for any malfunctions and service as required.

•

Lubricate every required part.

Lubrication •

Check the lubrication oil to make sure it is at the proper level and for contamination.

•

If necessary, add oil to the motor. If engine oil is contaminated, discharge it.

•

Lubricating oil deteriorates even when the machine is not used.

•

Check the oil before operating the machine again.

Battery •

Remove the battery and store it in a dry protected place.

•

If the battery is not removed, disconnect its negative terminal.

Coolant •

If there is a possibility that the coolant may freeze, add antifreeze in the coolant suitable for the outside temperature.

•

Normally, long life coolant is mixed in, so it is not necessary to change the coolant.

Dust and humidity prevention Store the machine in a dry and protected place.

Should the machine has to be left outside, position it on a wooden table and cover it with a waterproof sheet, placed so as to allow ventilation.

•

Retract as far as possible all cylinders rods.

Otherwise, coat the exposed cylinder rods with grease.

•

Lower the bucket to the ground and place wedges under the crawlers.

•

Lubricate all greasing points.

•

Paint parts needing it to prevent rust formation.

7-73

7 - MAINTENANCE

Care during storage Periodical lubrication during storage If the applied oil layer is insufficient, irregular wear may occur during the machine use.

Start the engine, operate the machine and the attachment, etc. once a month to lubricate all of the parts.

•

Before starting the engine, check the engine oil and coolant level. Top up, if necessary.

•

Remove rust preventing agent covering cylinders and rods.

•

Apply rust inhibitors to cylinder rods.

•

After starting the engine, warm up the machine completely. Operate the travel, rotation and digging functions 2 or 3 times to lubricate the sliding surfaces.

•

Ensure proper ventilation during warm-up operations.

Removal from storage Using the machine after prolonged storage Before placing the machine back into operation, proceed as follows before starting up: •

Fully wiped off the rust inhibitors from the cylinders and piston rods.

•

Refill fluids to proper levels and lubricate as required.

•

Thoroughly check all systems prior to operating the machine at full load.

•

Check condition of all hoses and connections.

•

Replace engine oil and fuel filters and top up engine oil.

Precautions • When parked in the sun heat When parked in the sun heat for long time, the temperature in the cab is greatly raised. In such case, open window fully and get the heat out, and then start operating the cooler. Close window after the inside of cab is cooled and control it to favourite temperature.

• Moderate cooling temperature The cooler refreshes by cooling down the temperature.

It is said that the temperature in which you feel slightly cool (The difference of temperature about 5 - 6 °C (41 43 °F) lower than atmospheric temperature) is good for health.

Too much cooling will give bad effect for health and therefore be careful for cooling temperature when controlling temperature.

• When glass is fogged up The glass is easily fogged up in rainy day and the visibility will be poor.

In this case, the fog is removed by operating cooler.

• When eyes are irritated When smoking in the closed cab eyes are irritated sometime. This is caused by dry air which weakens resistance of eyes.

In this case open window and get smoke out.

NOTE: If the cooler fail, stop the cooler and contact our service shop for checking. High pressure gas could spout out by loosening pipe connections and compressor section. Do not repair the cooler by yourself, contact our service shop.

The R134A refrigerant gas in use is a refrigerant with safety characteristics.

This means that this refrigerant is non-flammable, nonexplosive, nontoxic, non-irritating, tasteless and colorless.

Nevertheless, it is necessary to take some precautions.

Avoid any contact with the refrigerant. In case of skin contact with the refrigerant, immediately treat the skin.

Wear the safety glasses to protect your eyes. If although these measures the coolant comes in contact with your eyes, rinse them immediately with cold and clean water and then obtain medical attention immediately.

Empty the system before carrying out repairs on it. Do not let the refrigerant release in the surrounding areas.

To suck it, only use duly approved aspirators.

Regardless of the system being full of refrigerant or empty, heat determines a remarkable overpressure, which could not only damage the system, but also cause explosions.

Never expose the air conditioning components to a flame or a too hot heat source, to prevent fire or explosion hazard, with following emission of toxic gas.

Empty refrigerant cylinders must not be discarded. When full, refrigerant cylinders must not be exposed to sun rays or other heat sources for a long time. The maximum allowed temperature for a full refrigerant cylinder must not exceed 45 °C (113 °F).
