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 (*).

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).

LELI11E0216AA

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 or upper roller (2).

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

6 - WORKING OPERATIONS

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.

6-10

6 - WORKING OPERATIONS

Load The working efficiency can increase, if the dump truck collecting the removed earth is parked so that the rotation angle of the arm is minimal. At the same time the operator sight remains the best.

It is recommended that loading be started from the front side of the dump truck body. This will make loading easier and more soil can be loaded than by loading from the side.

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

1

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.

LELI11E0261AA

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.

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.

The hydraulic system of the machine can be set up to provide bidirectional power supply to attachments like nibbler or augers, and to provide unidirectional power supply to a breaker: see dedicated sections for proper system set up and operation.

10-1

10 - ACCESSORIES

Selection of hydraulic attachment Before fitting of the hydraulic attachment on the excavator, it is necessary to choose a model satisfying the required features as to stability, hydraulic pressure, and oil quantity of the hydraulic system. In order to choose the most suitable hydraulic attachment for the machine specifications, contact your Dealer.

NOTE: Max operating flow of hydraulic PTO is 40.7 l/min (10.8 US gpm). Max operating pressure of hydraulic PTO is 230 bar (3335 psi).

Before operating hydraulic attachment Contact your Dealer for pipings, for the installation of the hydraulic attachment and for the replacement of the hydraulic oil return filter, according to the maintenance schedule enclosed. Thoroughly read the hydraulic attachment operation manual and the safety instructions described in this manual to prevent damaging the machine or the hydraulic attachment during operation.

Prevention of hydraulic oil contamination Blanking plugs are provided on PTO connecting points for attachment hoses. When hydraulic PTO is not used, apply blanking plugs on machine connecting points and on attachment connecting points, to prevent the penetration of foreign bodies. Before starting operation, check the fixing clamps for looseness, and the tubes and hoses fittings for leakage.

AUX lines unload Hydraulic PTO is a high pressure hydraulic circuit. AUX have to be unloaded before connecting and disconnecting hydraulic attachment.

WARNING Escaping fluid!

Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or performing work on the hydraulic system. Before applying pressure, make sure all connections are tight and all components are in good condition. Never use your hand to check for suspected leaks under pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your doctor immediately.

Failure to comply could result in death or serious injury.

W0178A

To unload AUX lines, proceed as follows: 1. Park the machine on a level surface and rest the attachment to the ground.

2. Set engine speed to MIN and lock controls.

3. Open the hydraulic compartment; use an Allen wrench (2) to loosen and remove the screw (3).

Allen wrench: 5 mm 4. Use a wrench (4) to set the selector valve to proper position.

Load handling WARNING Improper operation or service of this machine can result in an accident.

When lifting a load the machine must be equipped with: - safety valves, - an overload indicator, - a load fixing point, - a load handling chart corresponding to the type of machine and to its attachment.

Failure to comply could result in death or serious injury.

W1168A

NOTICE: The machine has been specially designed for digging/loading operations. The moving of hanging loads to complete the working cycle digging and/or loading, is always allowed, only if the machine is equipped with specified optional equipment.

NOTICE: Carry out the handling of hanging loads by strictly following the national law concerning the prescribed safety rules, the national safety rules, the rules listed here below and those described on chapter safety rules.

For the handling of hanging loads, observe following: NOTICE: Before starting to work check the valves for any remarkable damage or abnormal noise. If troubles are noticed, refer to your dealer and, in the meantime, do not use the machine for handling hanging loads. To avoid injuries, do not exceed the machine load rated capacity.

If the machine is not set on a level ground, load capacities are reduced. Anyway, always operate with care.

Lower the dozer to the ground to increase machine stability.

Pre-arrange the engine RPM according to the hydraulic effort required.

Evaluate (if unknown) the weight of the object to be handled and compare it with the data of the table located in the cab and shown in this chapter. Do not lift loads exceeding the maximum values shown on the table.
