PROVEN PERFORMANCE

TO PREVENT ACCIDENTS The majority of accidents and injuries which occur in industry, at home or on the road, are caused by the failure of some individual to follow simple and fundamental safety rules or precautions. For this reason MOST ACCIDENTS CAN BE PREVENTED by recognizing the real cause and taking the necessary precautions, before the accident occurs.

Regardless of the care used in design and construction of any type of equipment, there may be conditions that cannot be completely safeguarded against, without interfering with reasonable accessibility and efficient operation.

A careful operator and / or technician is the best insurance against accidents. The complete observance of one simple rule would prevent many thousands of serious injuries each year.

This rule is: never attempt to clean, lubricate or adjust a machine while it is in motion.

Sď€ ď€ WARNING Before carrying out any maintenance operation, adjustment and or repair on machines equipped with attachments, controlled hydraulically or mechanically, make sure that the attachment is lowered and safely set on the ground. If it is necessary to have the equipment partially or fully raised to gain access to certain items, be sure the equipment is suitably supported by means other than the hydraulic lift cylinders, cable and /or

SECTION 01 - SAFETY PRECAUTIONS

GENERAL SAFETY INSTRUCTIONS

Carefully read this Manual before proceeding with maintenance, repairs, refuelling or other machine operations.

Repairs have to be carried out only by authorized and instructed staff; specific precautions have to be taken when grinding, welding or when using mallets or heavy hammers.

Not authorized persons are not allowed to repair or carry out maintenance on this machine. Do not carry out any work on the equipment without prior authorization.

Ask your employer about the safety instructions in force and safety equipment.

Nobody is allowed to seat on the operator’s place during machine maintenance unless he is a qualified operator helping with the maintenance work.

If it is necessary to move the equipment to carry out repairs or maintenance, do not lift or lower the equipment from any other position than the operator’s seat.

Never carry out any operation on the machine when the engine is running, except when specifically indicated.

Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves, etc.

All repair and maintenance operations should be carried out with the greatest care and attention.

Service stairs and platforms used in a workshop or in the field should be built in compliance with the safety rules in force.

Any functional disorders, especially those affecting the safety of the machine, should therefore be rectified immediately.

SECTION 01 - SAFETY PRECAUTIONS 1.1

EMERGENCY

Be prepared for emergencies. Always keep at disposal on the machine a first aid kit and a fire extinguisher. Make sure that the fire extinguisher is serviced in accordance with the manufacturer’s instructions.

1.2

EQUIPMENT

Wear close fitting clothing and safety equipment appropriate for the job: Z safety helmet; Z safety shoes; Z heavy gloves; Z reflective clothing; Z wet weather clothing.

If environment condition require it following personal safety equipment should be at hand: Z respirators (or dustproof masks); Z ear plugs or acoustic ears protections; Z goggles with lateral shield or masks for eyes protection.

Do not wear rings, wristwatches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open jackets or shirts with open zips which could get caught into moving parts.

SECTION 01 - SAFETY PRECAUTIONS ENGINE - RADIATOR

Never leave the engine run in closed spaces without ventilation and not able to evacuate toxic exhaust gases. Keep the exhaust manifold and tube free from combustion materials.

Do not refuel with the engine running, especially if hot, as this increases fire hazard in case of fuel spillage.

Never attempt to check or adjust the fan belts when the engine is running.

Never lubricate the machine with the engine running.

Pay attention to rotary pieces and do not allow to anyone to approach to avoid becoming entangled.

If hands, clothes or tools get caught in the fan blades or in the transmission belt, this can cause amputations, violent tears and generate condition of serious danger; for this reason avoid touching or to come close to all rotary or moving parts.

A violent jet of the coolant from the radiator can cause damages and scalds.

If you are to check the coolant level, you have to shut off the engine previously and to let cool down the radiator and its pipes. Slowly unscrew the cap to release the inside pressure.

If necessary, remove the cap with hot engine, wear safety clothes and equipment, then loosen the cap slowly to relieve the pressure gradually.

When checking the fuel, oil and coolant levels, use exclusively explosion proof classified lamps. If this kind of lamps are not used fires or explosions may occur.

SECTION 01 - SAFETY PRECAUTIONS 1.4

HYDRAULIC SYSTEMS

Splashes of fluids under pressure can penetrate the skin causing serious injuries.

Avoid this hazard by relieving pressure before disconnecting hydraulic or other lines.

Relieve the residual pressure by moving the hydraulic control levers several times.

Tighten all connections before applying pressure.

To protect the eyes wear a facial shield or safety goggles.

Protect your hands and body from possible splashes of fluids under pressure.

Swallowing hydraulic oil is a severe health hazard.

When hydraulic oil has been swallowed, avoid vomiting, but consult a doctor or go to a hospital.

If an accident occurs, see a doctor familiar with this type of injury immediately.

Any fluid penetrating the skin must be removed within few hours to avoid serious infections.

Flammable splashes may originate because of the heat near pipes with fluids under pressure, with the result of serious scalds for the persons hit. Do not weld or use torches near pipes containing fluids or other flammable materials.

Pipes under pressure can accidentally be pierced when the heat expands beyond the area immediately heated.

Arrange for fire resistant temporary shields to protect hoses or other components during welding.

Have any visible leakage repaired immediately.

Escaping oil pollutes the environment. Soak up any oil that has escaped with a proper binding agent.

Sweep up binding agent and dispose of it separately from other waste.

Never search for leakages with the fingers, but use a piece of cardboard and always wear goggles.

Never repair damaged piping; always replace it. Replace hydraulic hoses immediately on detecting any damage or moist areas.

Always store hydraulic oil in the original containers.

SECTION 01 - SAFETY PRECAUTIONS

HOSES AND TUBES Always replace hoses and tubes if the cone end or the end connections on the hose are damaged.

When installing a new hose, loosely connect each end and make sure the hose takes up the correct position before tightening the connections. Clamps should be tightened sufficiently to hold the hose without crushing and to prevent chafing.

After hose replacement to a moving component, check that the hose does not foul by moving the component through the complete range of travel.

Be sure any hose which has been installed is not kinked or twisted.

Hose connections which are damaged, dented, crushed or leaking, restrict oil flow and the productivity of the components being served. Connectors which show signs of movement from the original position have failed and will ultimately separate completely.

A hose with a frayed outer sheath will allow the water penetration. Concealed corrosion of the wire reinforcement will subsequently occur along the hose length with resultant hose failure.

Ballooning of the hose indicates an internal leakage due to structural failure. This condition rapidly deteriorates and total hose failure soon occurs.

Kinked, crushed, stretched or deformed hoses generally suffer internal structural damage which can result in oil restriction, a reduction in the speed of operation and ultimate hose failure.

Free-moving, unsupported hoses must never be allowed to touch each other or related working surfaces. This causes chafing which reduces hose life.

O-RINGS Replace O-rings, seal rings and gaskets whenever they are disassembled.

Never mix new and old seals or O-rings, regardless of condition. Always lubricate new seal rings and Orings with hydraulic oil before installation to relevant seats.

This will prevent the O-rings from rolling over and twisting during mounting which will jeopardize sealing.

SECTION 01 - SAFETY PRECAUTIONS 1.5

BATTERY

Batteries give off explosive gases.

Never handle naked flames and unshielded light sources near batteries, never smoke.

To prevent any risk of explosion, observe the following instructions: Z when disconnecting the battery cables, always disconnect the negative (-) cable first; Z to reconnect the battery cables, always connect the negative (-) cable last; Z never short-circuit the battery terminals with metal objects; Z do not weld, grind or smoke near a battery.

Battery electrolyte causes severe burns. The battery contains sulphuric acid. Avoid any contact with the skin, eyes or clothing.

Antidote: Z EXTERNAL: rinse well with water, removing any soiled clothing.

Z INTERNAL: avoid vomiting. Drink water to rinse your mouth. Consult a doctor.

Z EYES: rinse abundantly with water for 15 minutes and consult a doctor.

Z When the electrolyte of a battery is frozen, it can explode if you attempt to charge the battery or if you try to start the engine using a booster battery.

Always keep the battery charged to prevent the electrolyte freezing.

Provide good ventilation when changing a battery or using a battery in an enclosed space. Always protect your eyes when working near a battery.

Never set tools down on the battery. They may induce a short circuit, causing irreparable damage to the battery and injuring persons.

Never wear metal necklaces, bracelets or watchstraps when working on the battery. The metal parts may induce a short circuit resulting in burns.

Dispose of used batteries separately from other waste in the interests of environmental protection.

8 1.6

SECTION 01 - SAFETY PRECAUTIONS FLAMMABLE LIQUIDS

When handling flammable liquids: Z do not smoke; Z keep away from unshielded light sources and naked flames.

Fuels often have a low flash point and are readily ignited.

Never attempt to extinguish burning liquids with water. Use: Z dry powder; Z with carbon dioxide; Z with foam.

Water used for extinguishing purposes would vaporize instantaneously on contact with burning substances and spread burning oil, for example, over a wide area. Water generates short circuits in the electrical system, possibly producing new hazards.

Stay away from open flames during refilling of hydraulic oil or fuel.

Fuel or oil splashes can cause slipping and therefore accidents; clean immediately and accurately the areas eventually smeared.

Always tighten the safety plugs of fuel tank and hydraulic oil tank firmly.

Never use fuel to clean the machine parts eventually smeared with oil or dust.

Use a non-inflammable product for cleaning parts.

Always perform fuel or oil refilling in well aired and ventilated areas.

During refuelling hold the pistol firmly and keep it always in contact with the filler neck until the end of the refuelling, to avoid sparkles due to static electricity.

Do not overfill the tank but leave a space for fuel expansion.

Never re-fuel when the engine is running.

Take all the necessary safety measures when welding, grinding or when working near a naked flame.

SECTION 01 - SAFETY PRECAUTIONS 1.7

TYRES

Before inflating the tyres, always check the condition of rims and the outer condition of tyres to find out the presence of dents, cuts, tears of reinforcement plies or other faults. Before inflating a tyre, make sure that there are no nearby persons, then position yourself at tread side.

Make sure that the inflating pressure of tyres is the same prescribed by manufacturer and that the pressure of the right tyre corresponds to the pressure of the left tyre.

Never use reconditioned rims because possible welds, heat treatments or brazings not performed correctly can weaken the wheels and cause following damages or failures. Deflate the tyres before their disassembly.

Before taking out possible jammed objects from the rims, it is necessary to deflate the tyres. Inflate tyres by means of a pistol complete with extension and pressure switch of control.

1.8

CLEANING

Clean the exterior of all components before carrying out any form of repair. Dirt and dust can reduce the efficient working life of a component and lead to costly replacement.

Solvents should be checked that they are suitable for the cleaning of components and also that they do not risk the personal safety of the user.

Dirt from oil or grease and scattered tools or faulty pieces are dangerous for persons, because they can generate slipping or falls.

For the machine cleaning, use a jet of warm water or steam under pressure and commercial detergents.

Never use fuel, petroleum or solvents, because the first ones leave an oily layer that favours the sticking of dust, while solvents (even if weak) damage the paint and favour the formation of rust.

Never use water jets or steam on sensors, connectors or other electric components.

Prevent that the water jet penetrates inside the cab.

SECTION 01 - SAFETY PRECAUTIONS WASTE DISPOSAL

Improperly disposing of waste can threaten the environment.

Each country has its own Regulations on this subject. It is therefore advisable to prepare suitable containers to collect and store momentarily all solid and fluid materials that must not be scattered in the environment to avoid pollution.

At preset intervals these products will be delivered to disposal stations legally recognized and present in this Country.

Hereunder are listed some products of the machine requiring disposal: Z lubricating oil; Z brakes system oil; Z coolant mixture, condensation rests and pure antifreeze; Z fuel; Z filter elements, oil and fuel filters; Z filter elements, air filters; Z battery.

Also polluting rags, paper, sawdust and gloves must be disposed in compliance with the same procedures.

Do not use food or beverage containers that may mislead someone into drinking from them. Do not pour waste onto the ground, down a drain, or into any water source. Air conditioning refrigerants escaping into the air can damage the Earth’s atmosphere. Government regulations may require a certified air conditioning service centre to recover and recycle used air conditioning refrigerants. Obtain information on the proper way to recycle or dispose of waste from your local environmental or recycling centre, or from your Dealer.

SECTION 04 - UPPER STRUCTURE

SLEWING BEARING

The slewing bearing consists of an external ring integral to the upper structure, an internal ring integral to the undercarriage and a single (MH 5.6) or double (MH City - MH Plus) series of balls.

The pinion of the rotation gearbox, controlled by the rotation motor by means of the gears of the gearbox itself, rotates around its own axis and makes a revolution around the centre of the internal ring of the slewing bearing, thus enabling the upper structure to rotate independently from the undercarriage.

SECTION 04 - UPPER STRUCTURE

DISASSEMBLY Park the machine on a level and firm surface.

Lower the attachment to the ground.

Lower the blade and the stabilizers to the ground.

Engage the parking brake.

Lock the upper structure.

Stop the engine.

Place some wedges under the wheels so as to prevent the machine from moving.

Move both hydraulic control levers in all directions, to release possible residual pressure inside the hydraulic system.

For slewing bearing disassembly, it is necessary to remove the upper structure.

Disconnect all hydraulic hoses and electric harnesses from the rotary control valve and from the rotor.

Close all openings on pipes and rotary control valve with plugs in order to prevent dirt from entering.

By using chains or ropes (with a carrying capacity of 20000 kg (44000 lb)), sling the upper structure in its front and rear part.

Hook these ropes to two cranes (with a lifting capacity of ~ 20000 kg (44000 lb) each) and slowly tension them without lifting the upper structure.

Please remember that the internal ring (1) of the slewing bearing is fastened to the undercarriage and that the external ring (2) is fastened to the upper structure.

Loosen and remove the screws (3) from the slewing bearing’s external ring (2). Keep the spacers (5) because they will be reused.

Now the upper structure is detached from the undercarriage.

Carefully lift the upper structure, until the pinion of the rotation gearbox is freed. Turn the upper structure away from the undercarriage.

Using a hoist, hook the slewing bearing (7).

For this operation, insert 3 threaded eyebolts (8), staggered by 120°, into the holes, fastening them with the nuts (9).

Loosen and remove the screws (4) and keep the spacers (6) as they will be reused.

Lift the slewing bearing (7) and remove it from the undercarriage.

SECTION 04 - UPPER STRUCTURE ASSEMBLY When the slewing bearing is new, eliminate the anticorrosive protection coat.

Carefully clean all supporting surfaces of the undercarriage and the upper structure. The metal of the supporting surfaces must be bright, clean and degreased. Eliminate projections and burrs.

Clean the holes of the undercarriage. Carefully clean the threaded holes of the upper structure and check the threads. If damaged, pass them again with the screw tap.

Apply the adhesive to the supporting surface of the undercarriage. For this operation, use a painting roller, a hard brush or a plastic spatula.

Do not let the adhesive enter the holes. Adhesive on threads causes higher friction and, therefore, an alteration of the tightening torque.

Hook the new slewing bearing to the hoist.

Rotate the internal and the external ring so that the mark (S) on the external ring is at 90° to the travel direction, and the mark (S) on the internal ring is on the opposite side.

SECTION 04 - UPPER STRUCTURE

Rotate the slewing bearing on the undercarriage and leave it hanging above the supporting surface, without resting it. As a guide, screw in at least three new screws (4) with relevant spacers (6).

Carefully rest the slewing bearing and disconnect the hoist from the slewing bearing.

Screw in all remaining new screws with the relevant spacers and cross-tighten them using a torque wrench.

Tightening torque: MH City = 270 Nm (199.14 lbf路ft) MH Plus - MH 5.6 = 280 Nm (206.52 lbf路ft) Mark the screws (4) already tightened.

Apply the adhesive, as described, also to the supporting surface of the upper structure.

Apply grease in a level coat to the teeth of the slewing bearing, so that the gaps between the teeth are completely filled.

Rotate the upper structure on the undercarriage and leave it hanging above the slewing bearing without resting it.

Carefully continue lowering the upper structure, inserting the pinion between the teeth.

As a guide, screw in at least three new screws (3) with relevant spacers (5).

Carefully release the upper structure.

Screw in all remaining new screws (3) with the relevant spacers (5) and cross-tighten them using a torque wrench.

Tightening torque: MH City = 270 Nm (199.14 lbf路ft) MH Plus - MH 5.6 = 280 Nm (206.52 lbf路ft) Mark the screws (3) already tightened.

Connect all hydraulic hoses and electric harnesses again to the rotary control valve and to the rotor.

Remove the ropes from the upper structure.

Fill and bleed air from the hydraulic system. Operate the machine and check all hydraulic hoses for tightness.

The adhesive between the slewing bearing and the upper structure and between the slewing bearing and the undercarriage increases the load capacity of the screwed connection and contemporarily serves as a seal between the gaps.

The adhesive hardens when exposed to air.

A definitive rigidity is obtained after ca. six hours.

Fully load the machine only after this time has elapsed.

ROTATION GEARMOTOR

The rotation device consists of an hydraulic motor (1) and a gearbox (2). The hydraulic motor consists of an axial-piston motor. The gearbox is used to rotate the upper structure by means of the coupling of the relevant pinion (3) with the internal teeth of the slewing bearing. The rotation device is installed on the main frame of the upper structure.
