OPERATING INSTRUCTIONS EW 220

Organizational measures The operating instructions must always be at hand at the place of use of the machine, e.g. by stowing them in the tool compartment or tool-box provided for such purpose.

In addition to the operating instructions, observe and instruct the user in all other generally applicable legal and other mandatory regulations relevant to accident prevention and environmental protection.

These compulsory regulations may also deal with the handling of hazardous substances, issuing and/or wearing of personal protective equipment or traffic regulations.

The operating instructions must be supplemented by instructions covering the duties involved in supervising and notifying special organizational features, such as job organization, working sequences or the personnel entrusted with the work.

Personnel entrusted with work on the machine must have read the operating instructions and in particular the chapter on safety before beginning work. Reading the instructions after work has begun is too late. This applies especially to persons working only occasionally on the machine, e.g. during setting up or maintenance.

Check - at least from time to time - whether the personnel is carrying out the work in compliance with the operating instructions and paying attention to risks and safety factors.

For reasons of security, long hair must be tied back or otherwise secured, garments must be close-fitting and no jewellery, such as rings, may be worn. Injury may result from being caught up in the machinery or from rings catching on moving parts.

Hydraulic system All working and travel movements are executed hydraulically. The working commands are triggered manually and transmitted via control circuits. The oil flow from the superstructure to the undercarriage passes through the rotor. The hydraulic system is protected against overloading by pressure relief valves.

Steering The machine is equipped with a hydrostatic power steering system enabling the machine to be steered manually by applying increased force if the engine is stationary or in case of hydraulic steering pump failure.

Service brake The machine is braked by hydraulically operated multiple-disk brakes on all four pairs of wheels.

The service brake can be blocked in braked position.

Parking brake The parking brake is formed by spring-pressureblocked disk assemblies.

The parking brake is integrated into the travel gearbox and therefore acts on all wheels.

Floating axle The steering axle is of the fully floating type. This axle can be blocked hydraulically by means of two cylinders during excavator operation.

Electrical system Undercarriage The undercarriage of the hydraulic excavator serves as a stable base when the excavator is stationary and for travelling.

The undercarriage also carries the components used for stabilizing and supporting of the machine during working operations such as the levelling blade or the stabilizers.

The undercarriage is hydraulically driven with oil motor and transmission.

Undercarriage and superstructure are linked by a swing ring.

The electrical system operates on 24 volts.

An electronic voltage regulator moreover supplies a voltage of 12 V. Electronic modules (Power Control System) ensure that the available engine power is converted in an optimal way into hydraulic power.

Working equipment The working equipment comprises the monoblock boom, the stick, the toggle lever with toggle link and the backhoe bucket (multi-position-boom with lower and upper section is optional equipment). Further excavating or working tools can be attached.

Superstructure The drive motor and part of the hydraulic and electrical systems are housed in the superstructure.

OPERATING INSTRUCTIONS EW 220 Cab interior lamp - switching on and2800862 off The interior lamp is switched on and off with the switch (Fig. 17).

Important: The lamp can be switched on even if the keyswitch for the electrical system is in OFF position and the key is withdrawn.

If the light is left on inadvertently for a longer period (e.g. a weekend), the batteries may be discharged.

So always check that the interior lamp is switched off before leaving the machine.

Fig. 17

Socket outlet in cab 2904422

A socket outlet is installed in the panelling on the left behind the operator’s seat (Fig. 18).

This provides the output voltage of the voltage transformer (12V) for connection of the cool-box (option). Other electrical consumers can also be connected as long as the maximum output of the voltage transformer is not exceeded.

Important: The voltage transformer installed at the factory is designed so as to supply not only a cassette radio but also the cool-box (option); the maximum output is 90 W. In the event of overloading, the temperature of the transformer increases and causes the built-in overload protection to switch off leaving the connected appliance without current. In this case, pull the plug out of the socket (Fig. 18). After 5 10 minutes, the overload protection has cooled down and switches the transformer back into the circuit. If the overload condition persists, the thermal overload shut-off does not work anymore and the fuse in the electrical supply cable blows. To replace it, the panelling below the radio must be removed.

The socket is still live when the key-switch for the electrical system is in OFF position and the key is withdrawn.

If a connected consumer is left on inadvertently for a longer period (e.g. a weekend), the batteries may be discharged.

So always check that the connected consumer is switched off before leaving the machine.

OPERATING INSTRUCTIONS EW 220 MONITORING-, WARNING- AND CONTROL ELEMENTS The tables on the following pages inform you about the functions of - the control panel, - the supplementary control panel and - all control elements.

More information on the different functions can be found in other chapters of these operating instructions.

If you want to find information on a specific subject please refer to the table of contents and the index.

2801386

At low winter temperatures (approx. below -20oC / -4oF), the multi-functional display (A, Fig. 1) may be difficult to read or not readable at all. This is not a malfunction but rather a phenomenon due to the liquid crystal technique used.

After a short time of operation, the display can again be read in full contrast.

The control panel layout is identical for excavators of the EC and EW series. For this reason, functions and elements required for wheel-mounted ecxavators are not used for crawler-trackmounted machines such as, for instance, the steering pressure warning lamp (no. 7).

The control panel is subdivided into four functional groups of elements:

Some of the keyboard functions are options. They can only be used if the machine is equipped correspondingly and if the function has been validated on the PCS electronic unit board, e.g.:

- the multi-functional display (A, Fig. 1),

- hydraulic hammer (key 19),

- indicator and warning lamps (B),

- overload warning system (key 29).

- the keyboard (C) and

Not all of the functions indicated on the control panel are available for each type of machine. If you have questions, please contact your nearest NEW HOLLAND CONSTRUCTION dealer-service.

Description of control panel

- the supplementary control panel (D, Fig. 2).

The whole control panel is automatically illuminated as soon as the key-switch is turned to position 1 (ignition ON).

73179376

OPERATING INSTRUCTIONS EW 220 Control panel operating instructions The keyboard is a membrane-type keyboard with symbols printed on the membrane describing the function of the key below.

2801562

Example (Fig. 3): Key (15), fan

The keys are depressed to activate or de-activate the corresponding functions. The keys are shortstroke tactile touch types telling the operator by a click that the key has been successfully depressed.

Light-emitting diodes (LEDs) are located above the keys under transparent sections of the keyboard membrane to indicate the control state of the key. Depressing the key repeatedly permits to select all possible control states sequentially (see example opposite).

Fig. 3

The keyboard membrane may be damaged by pointed objects.

Use your fingers only to depress the keys.

Never use ball-point pens, pencils, nails or similar pointed objects.

Possible control states: - none of the LEDs lit = fan OFF. - key (15) depressed once: = fan in range 1, LED above 1 on.

- key (15) depressed twice: = fan in range 2, LED above 2 on.

After shutting off the machine (ignition OFF), the last switching state of the keys "Fan" (15), "Hydraulic Hammer" (19), "PCS-range (20), "AutoIdle" (22), "Swing mode" (26), "Gearshift" (27), "Blocking the service brake" (key 81) and "Overload warning system" (29) remain stored and are being displayed when the machine is started next time.

All other activated functions are reset to zero.

The following rule applies to the rocker switches on supplementary control panel (D, Fig. 2): A function is activated when the switch face bearing the function symbol / the description is depressed.

- key (15) depressed three times: = fan in range 3, LED above 3 on.

- Depress key (15) four times: = fan in stage 2, LED above 2 lit up.

- Depress key (15) five times: = fan in stage 1, LED above 1 lit up.

- If the key is depressed again: = fan OFF, LED extinguished.

It is not possible to pass directly into the OFF position from a selected range. This means that if the operator wants to switch off the fan running in range 1 he has to depress the key five times.

The other keys are operated the same way.

The key-switch (46, Fig. 2) is used to switch the following functions: 0 = All electrical consumers except the interior light, turn signals, outlet in cab, hazard warning system, refuelling system and illuminating systems are without voltage, engine off.

I = Electrical system ON. If the immobilizer is active, the system now requests entering of the code (see: "Immobilizer, entering the code").

If the immobilizer is not active, the electronics will perform a self-test.

All monitoring and warning lamps will light up for a few seconds and the buzzer sounds briefly.

Then, warning lamps (7, 9, 36, 40, 42, Fig. 3) will light up and the buzzer will sound again.

All indicators will be shown at the display.

The pre-glow timing device is activated.

The electronic unit now switches the following functions: - The PCS is switched to the mode that was active during the preceding engine shut-off, - Superstructure holding brake in AUTOMATIC mode.

OPERATING INSTRUCTIONS EW 220 Immobilizer, entering the code This machine is equipped with an electronic immobilizer system preventing the machine from being put into operation by unauthorized persons.

The immobilizer function is not enabled when the machine is delivered ex factory. On request of the customer, it can, however, be activated by the service mechanic when the machine is handed over.

When the electrical system is switched on by turning the key-operated switch, the electronic central unit requests entering of a code (Fig. 4).

The engine can be started up only after the code has been entered correctly.

During the work, the immobilizer can be deactivated (see also: "Immobilizer, deactivating / activating").

2904030

Fig. 4

Entering the code (f. ex. "5"): • Turn keyswitch to I. • Depress key (24, Fig. 5) five times: the display (A) moves on by one unit after each depression of the key.

• Depress key (25) five times: the display (A) moves back by one unit after each depression of the key.

The start inhibit function is now cancelled. The machine can be put into operation.

• After an incorrect entry, the procedure can be interrupted and restarted by setting the keyswitch to "0" and by repeating the procedure from the beginning. (cf. "Immobilizer, deactivating / activating").

Fig. 5

N.B.: The code preset at the factory can be changed.

This requires, however, a specially equipped tester.

Contact your NEW HOLLAND CONSTRUCTION dealer if you want to have the code changed.

The new code must be entered as described above.

Make sure the information on the new codes is not accessible to unauthorized persons.

You can thus be sure that your machine can only be put into operation by duly authorized persons.

Allow no other persons to accompany you on the machine during driving.

Do not drive with the working equipment stretched out. The machine may loose its stability. Retract the working equipment as far as possible towards the machine.

Do not pull trailers The machine is not suited for the towing of trailers or other vehicles over greater distances. Towing over greater distances would result in damage to axles and gearboxes. The coupling is intended for recovering or towing the machine out of the hazard range after an accident or for attaching the fixing ropes on transport vehicles. See "Recovering and towing the machine".

During reversing the acoustic Travel Alarm is automatically switched on.

Parking the machine Machines parked on sloping terrain may move inadvertently.

The machine must therefore be parked on level and horizontal ground.

Contact with overhead power lines Raise the working equipment only in so far as required to pass under such lines without any risk.

If a power line has been contacted, drive the machine out of the hazard range or lower the working equipment.

If this is not possible: - Do not leave the driver’s cab.

- Inform persons outside the hazard zone to keep away from the machine and to take the necessary steps to have the power line shut off.

OPERATING INSTRUCTIONS EW 220 Blocking the swing axle

2796514

The steering axle is suspended on the undercarriage in such a way that it can swing transversely to the longitudinal axle of the machine (swing axle). This is advantageous when driving over uneven terrain. When working however, this swinging motion has to be prevented by disabling the oil exchange between two hydraulic cylinders which are supported on the axle. This blocks the swing axle so that the stability of the machine is substantially increased.

Before travelling again with the machine, the swing axle must be released again (exception: see "Driving with a load on the hook").

Blocking the swing axle

Fig. 13

• Switch rocker switch (52, Fig. 13) downwards; the surface with the symbol is pressed down.

Releasing the swing axle • Switch rocker switch (52) upwards; the surface with no symbol is pressed down.

Important: If the swing axle is released (rocker switch (52) surface without symbol pressed down), the swing axle is automatically blocked when the parking brake is applied or when the service brake is blocked.

The swing axle is automatically released again when the parking brake or the service brake is released.

Second stage: The engine is set to idling speed if the working equipment is not used for more than 4 seconds.

This reduces fuel consumption as well as noise and exhaust emissions.

(This period, which is set at the factory, can be changed. However, this requires a specially equipped test unit.

So consult your NEW HOLLAND CONSTRUCTION dealer-service if the period is to be changed).

If the operator activates a hydraulic function, the engine is brought back to the previously set speed.

The switch position of the Auto Idle function (ON / OFF) is stored when the engine is shut off.

73179376

OPERATING INSTRUCTIONS EW 220 Braking the superstructure The swing movement of the superstructure is braked when the swing control lever (78, Fig. 12) returns to position 0.

Adjustable swing brake valves determine the delay in braking. The period from the releasing of the swing control lever until the superstructure is stationary can thus be adapted to meet individual requirements.

Consult your NEW HOLLAND CONSTRUCTION dealer-service.

The braking action is reinforced by countering (i.e. by pressing the swing control lever in the opposite direction).

Swinging - changing the mode of operation

2800880

The swinging drive can be switched between two different modes of operation with key (26, Fig. 13).

Changing the mode has an effect on the "boom lift" function.

- LED I above key (26) on = normal hydraulic power for swinging movements.

At the same time, more hydraulic power is available for the "boom lift" function.

This mode of operation should be selected whenever there is only a small amount of swinging to be performed during the work.

- LED I above key (26) off = increased hydraulic power available for swing movements. There is no influence on working equipment functions.

OPERATING INSTRUCTIONS EW 220 Superstructure retaining brake function

2800866

A multi-disc brake is fitted in the swing gear. It is applied by spring pressure and released by hydraulic pilot control pressure.

The retaining brake is not applied until the swing control lever is in 0 position and the swing motion of the superstructure is terminated. Therefore it cannot be used to brake the swing movement.

With the keyswitch in the OFF position, the engine stationary or in case of machine voltage failure, the superstructure holding brake is applied. and the superstructure is braked.

Applying the superstructure retaining 2732896 brake The superstructure retaining brake can be used in three modes of operation: • Key (28, Fig. 15) not depressed, LEDs extinguished: holding brake released, superstructure free to swing.

• Key (28) depressed once, LED I lit up: holding brake applied, superstructure braked.

The pilot lamp (41, Fig. 16) lights up.

• Key (28, Fig. 15) depressed twice, LED A lit up: automatic mode, the holding brake is being applied automatically when the superstructure is stationary and released when a swing movement is initiated. This mode is activated automatically when the engine is started.

The pilot lamp (41, Fig. 16) lights up if the superstructure holding brake is applied for more than 10 seconds.

73179376

OPERATING INSTRUCTIONS EW 220 Releasing the superstructure retaining brake • Depress key (28, Fig. 15) until the LEDs above the key are extinguished. The holding brake is released and the superstructure is free to swing.

In the "Automatic" mode of operation with LED A lit up, the holding brake is released as soon as the swing control lever is deflected.

This mode is activated automatically when the engine is started.

Superstructure holding brake emergency operation

2904409

The superstructure may be swung freely if the superstructure holding brake is released using emergency operation!

Then the superstructure is not braked automatically after a swing movement.

When working on a slope or if the machine is in a sloping position the superstructure can continue swing independently if the swing movement is not countered.

To avoid dangerous situations, emergency operation should only be used in exceptional circumstances.

Rectify superstructure holding brake malfunctions immediately (or have them rectified).

The pilot control pressure to release the superstructure holding brake is controlled by a solenoid valve.

If a malfunction occurs at the solenoid valve the superstructure holding brake can be released using emergency operation.

The solenoid valve is attached in the frame behind the driver’s cab (Fig. 17).

• Turn grub screw (Fig. 17) fully down using an Allan key size SW 3. The superstructure holding brake is released, the superstructure swings freely.

• Rectify solenoid valve malfunctions immediately (or have them rectified).

• Turn grub screw completely back out when the fault has been rectified.

OPERATING INSTRUCTIONS EW 220 Operating methods

2801516

Read and observe the section: "Working operation - Safety instructions".

• Use arm pull action often. When digging, use the arm pulling force and operate the bucket using shallow teeth cuts.

Deep teeth cuts will decrease efficiency (Fig. 1).

• Point the bucket teeth in the direction of digging. This will decrease digging resistance and possible damage to the teeth (Fig. 3).

Fig. 1

Fig. 3

• Operate boom smoothly. When moving the boom up and down, begin and end the operation very slowly and smoothly. When the boom is stopped suddenly, strong shocks are exerted upon the machine body, causing excessive wear and possible damage (Fig. 2).

• Maximum digging force is obtained with 90˚ ~110˚ angles. When maximum digging force is needed, dig earth slowly having the boom and the arm at nearly 90˚ ~110˚ (Fig. 4).

Fig. 2

Fig. 4

73179376

OPERATING INSTRUCTIONS EW 220 • How to shake off sand and soil on the bucket.

Push the arm to near level position and bring the bucket to a dumping position. If sand and soil do not fall out, move the bucket lever back and forth a few times. Avoid shaking out soil using shocks at the end of the bucket cylinder stroke (Fig. 5).

Fig. 7

• Land leveling work. For back filling and leveling work after digging, move the bucket back and forth horizontally (Fig. 7).

Fig. 5

• Stop swing motion early. To stop swing action, release the swing lever before you get to your final point of digging or dumping (Fig. 6). (cf.: "Swinging and braking the superstructure")

Do not push and pull earth by the bucket like a bulldozer, while the machine is leveling earth, off. Use the levelling blade.

In leveling ground toward yourself, pull the arm gently, lift the boom a little and when the arm has passed the vertical point, lower the boom gently and manipulate the machine so the bucket moves horizontally.

For leveling ground away from yourself, reverse the steps described above.

In the above operation, bucket motion may be used together. By controlling the action of the boom work lever, you can dig a slope like slope facing operation.

Never travel with attachment touching the ground. Severe structural damage could occur.

OPERATING INSTRUCTIONS EW 220 Corrosion protection for pins and bearings (bushings and hubs)

2801355

Application of Voler A.C. Use Voler A.C. anti-corrosive agent only.

Other agents are not approved by NEW HOLLAND CONSTRUCTION. All pins and bearings (bushings and hubs) of the working equipment or in equipment components must be treated with Voler A.C. anti-corrosive agent before fitting.

Voler A.C.: • permits easy fitting and dismantling • protects against rust, oxidation and similar wear • prevents seizing and fretting corrosion in nonmoving parts of bearings.

This is achieved by aluminium and copper particles forming a protective layer on the metal. This layer removes surface irregularities and does not sweat, seize or harden.

Part nos. for Voler A.C. P/N 73171461 - 0,5 l spray can (CFC-free)

• Clean off grease, oil, dirt and corrosion protection agents from pins and bearings using white spirit or diesel fuel.

Rust patches must be thoroughly removed, if any.

All parts must present a dry, bright metal surface.

• Apply a thin layer of Voler A.C. on pins and all bearings using a brush or a spray can. Pin shafts and bearings must be completely covered by the protective layer.

If the protective layer of a pin already treated with Voler A.C. is damaged, these areas must be touched up before fitting the part.

OPERATING INSTRUCTIONS EW 220 LIFTING-GEAR OPERATION Lifting-gear operation - safety instructions

Never use the machine for lifting-gear operation unless it is equipped and approved for this purpose.

The machine must be equipped with an overload warning system and pipe-fracture safety devices.

Read the sections "Fundamental safety instructions" and "Operation, safety instructions" with care and observe the instructions contained in them.

Switch the overload safety device on before starting work.

Room for slingers Slingers must approach the working gear from the side when the load is slung.

2413662

Sling the load in such a way as to prevent it from slipping or falling while being lifted or transported.

Transporting the load Never move the load above persons. Keep the load as close as possible to the ground.

Prevent the load from swinging.

The machine must never be driven with a slung load unless the road surface is even and the roadway is clearly visible.

Roadway visibility can be improved by adjusting the boom and swinging the superstructure to the right.

Use only tested and efficient lifting gear with an adequate load capacity.

The built-in overload warning device cannot totally exclude accidents due to incorrect operation. This applies in particular to: - inadequate hooking of the load or the load-carrying device, - excessive deceleration or acceleration forces (hard braking or strong swinging with the load to be moved), - loads dropping into the cable, - oblique pull, - driving the excavator into an area with steeply sloping ground, - exposure to strong wind.

Hoist the load only from the hooks provided for that purpose.

Avoid these risks by handling the machine carefully and with discretion.

During the lifting and transporting of loads, slingers or other assistant personnel must stand in a safe position or go beside the machine to ensure that they are outside the hazard zone.

Ensure that slingers and other assistant personnel are always in sight.

Slinging loads

Never use the teeth of backhoe dippers, buckets or grippers.

Cable lugs, thimbles or U-bolts may slip from the teeth, putting the load out of control.

Register the weight of the load. Sling only those loads not exceeding the load capacity of the lifting gear and of the machine (cf. "Technical data").

116

73179376

OPERATING INSTRUCTIONS EW 220 Loading hooks on backhoe buckets and couplers

2732886

(optional equipment) To enable hydraulic excavators to be used for lifting purposes too, backhoe buckets and couplers are available with welded loading hooks (Fig. 1 and 2) (option).

Before attaching loads: Read and observe: "Lifting gear operation - Safety instructions".

Switch on the overload warning system before starting work.

Loading hook capacity The maximum capacity of the loading hook is marked on the hook (Fig. 1 and 2).

Excavator load capacity The admissible load capacity depending on working equipment and working radius is given in the "Load capacities" table, cf. "Technical Data".

Attach the load only to the load hook provided for this purpose.

Extra important for load hook on linking element: If a different working attachment (e.g. a grab) is mounted instead of the backhoe, the linking element and toggle lever must be joined with a locking pin.

In this case the load hook must not be used for lifting loads.

The locking pin is not designed for such loads and may bend or suddenly break. In this case the linking element and attached load suddenly start to swing.

Fig. 1

The swinging load may get out of control, resulting in injury or damage. In extreme cases, the stability of the machine may be at risk.

So: Never attach loads to the load hook of a locked linking element.

Always use the load hooks/lugs on the attachment (e.g. grab). If the attachment is not equipped with a load hook but a load has to be moved, the locking pin can be removed from the linking element and toggle lever as long as the load hook on the linking element has to be used.

OPERATING INSTRUCTIONS EW 220 Overload warning system

2461493

(optional equipment)

Function of overload warning system

Activating the overload warning system 2461494 The overload warning system can be operated in two modes:

The overload warning system gives only warning signals; it does not prevent overturning.

When the warning signal sounds: - let down load immediately, - reduce working radius or weight of load.

Hydraulic excavators used as lifting devices or for the transport of loads must be equipped with an overload warning system and an pipe-fracture safety system for the lifting cylinders of the working hydraulics.

• Depress key (29, Fig. 4) once, LED 1 lights up = if the machine is used without additional stabilizers for lifting operations.

• Depress key (29) twice, LED 2 lights up = if the machine is used with additional stabilizers (levelling blade/stabilizer feet) for lifting operations.

The overload warning system must be on when such works are carried out.

If the admissible load moment is exceeded, warning lamp (11, Fig. 3) lights up and the buzzer sounds.

Fig. 4

Before the machine is being used for lifting operations, the overload warning system must be activated: • Switch the overload warning system with key (29) into the required mode of operation.

The LED above the key lights up.

Fig. 3

• Checking the overload warning system (cf.

"Checking the overload warning system").

The overload warning system is now ready for operation.

The admissible load moment is exceeded when too heavy a load is being lifted at a great working radius of the working equipment (lifting capacity cf. section "Technical data").

118

73179376

OPERATING INSTRUCTIONS EW 220 Testing the overload warning system 2801523

Check correct function of the overload warning system: - daily before starting operation and

Putting the overload warning system 2461496 out of operation If the machine is used exclusively for excavating operations, the overload warning system can be put out of operation:

- before each lifting-gear application.

Fig. 6 Fig. 5

• Activate overload warning system (cf. "Activating overload warning system".

• Depress key (29, Fig. 6) until the LEDs are no longer lit up.

The overload warning system is now out of operation.

• Raise boom to highest position limit stop.

• The warning light (11, Fig. 5) indicates and the buzzer sounds).

If an error occurs have the overload warning system tested and repaired immediately by NEW HOLLAND CONSTRUCTION. The adjustment or inspection is confirmed by a certificate.

Never carry out setting of or repairs to the overload warning system yourself.

Correct function of the overload warning system could be impaired or it could fail completely.

OPERATING INSTRUCTIONS EW 220 Pipe-fracture safety system, function (Option) The pipe-fracture safety system prevents the working equipment from being lowered if a hydraulic line to the boom cylinder piston side fractures.

The hydraulic connection at the piston side of the boom cylinder is blocked. hydraulic oil can only flow out here when the "lower boom" function is operated.

With machines with multi-position boom, additionally to the boom cylinders, the adjusting cylinder of the boom upper section is also equipped with a pipe-fracture safety device at the rod side.

2413657

If a hydraulic line is fractured: • Operate the control lever for the "lower boom" function to 0 position.

• Warn people in the vicinity using the horn.

• Secure the range of the working equipment and suspended load, so that persons cannot remain under the working equipment and load or in the vicinity of the fractured hydraulic line.

When the working equipment and the load are lowered to the ground, oil flows out of the hydraulic line at the fracture.

• Carefully lower working equipment and load to the ground.

• Replace fractured hydraulic line (or have it replaced).

Only then resume operation.

• Collect escaped hydraulic oil. Dispose of oilsoaked rags, oil-binding agent, etc. in an environmentally responsible manner.

Operating manual

Securing working equipment

No inspection and servicing work may be carried out until the operating manual has been read and understood.

Pay special attention to the:

Stand working equipment on the ground in such a way that no movements can be made if mechanical or hydraulic connections become detached.

"Fundamental Safety Instructions" and all warnings and safety instructions attached to the machine.

When working in jointed areas, block off the joints. Remove the blocks on finishing work.

The operating manual lists all jobs to be done. The descriptions of job sequences, however, provide only experienced personnel with the necessary instructions.

Secure any equipment or component which is to be mounted or dismantled, or whose position is to be changed, with hoists or appropriate slinging/supporting devices to prevent them from moving, slipping or falling inadvertently.

The operating manual must be kept with the machine at all times.

Inspection and servicing personnel Inspection and servicing personnel must have the necessary know-how on the inspection and servicing of this or comparable machines.

Securing the machine Carry out servicing work only if the machine is secured as described in the section "Securing the Machine".

Climbing onto and off the machine Personal protective equipment and working clothing Wear closely fitting working clothing when working on the machine. Loose, wide garments may catch on machine parts and result in injury.

Wear a safety helmet, safety goggles, safety footwear, gloves and, in the event of high noise levels, ear protectors.

Use only the steps, platforms and handrails provided when climbing onto or off the machine.

Always keep steps, platforms, handles and handrails in a non-slip, safe state and remove any oil, grease, soil, clay, snow, ice and other foreign matter immediately.

Always face the machine when climbing on and off.

Check state of tools Use only fully functional, reliable tools.

Select the right tool for the job.

Wrenches of the wrong size, for example, may slip and cause injury.

OPERATING INSTRUCTIONS EW 220

Cleaning jobs

Fastening and securing elements

Clean the units within the working range before starting work.

Select the cleaning agent according to the material constituting the parts to be cleaned.

Check fastening and securing elements, e.g. bolts, nuts, washers, before using them again.

Replace any damaged parts.

Example: Never clean rubber or electrical parts with solvents or steam jets.

Use lint-free cleaning rags when working on the hydraulic system or the engine.

Cleaning agents and solvents may give off harmful, readily flammable vapours.

Never work with such agents except on well ventilated premises; never inhale the vapours and never smoke.

Prevent solvents and cleaning agents from coming into contact with the skin.

Wear gloves.

Observe the instructions on the packaging.

Handling flammable liquids When handling flammable liquids: - never smoke, - keep away from unshielded light sources and naked flames.

Fuel and other consumables often have low flash points and are readily ignited.

Never attempt to extinguish burning liquids with water. Use - dry powder, - carbon dioxide or - foam extinguishers.

Handling oils and greases Hot lubricant or hydraulic oil emerging uncontrolled from the system may result in severe burns.

Never set foot within reach of the emerging oil jet.

Avoid contact with the skin. Wear gloves and firm protective clothing.

Used oil may be harmful to the skin.

Clean soiled skin thoroughly with warm soapy water and apply a barrier cream.

Never use fuels or solvents for cleaning the skin.

If you have swallowed any oil, avoid vomiting but consult a doctor immediately.

Visible loss of oil Have any visible leakage repaired immediately.

Escaping oil is an environmental hazard.

Soak up any oil that has escaped with a binding agent. Sweep up binding agent and dispose of it separately from other waste.

Water used for extinguishing purposes would vapourize 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.

Notify the fire brigade.

73179376

OPERATING INSTRUCTIONS EW 220

Relieving residual pressure in the hydraulic system

Environmentally compatible disposal

Only unpressurized hydraulic systems may be opened. Even when a machine is parked on a horizontal surface with its attachments supported on the ground and its driving motor switched off, there may still be substantial residual pressure in parts of the hydraulic system, e.g. primary pressure from the last hydraulic movements prior to stopping the machine.

Oils, greases, brake fluids, cleaning agents, solvents and oily components, e.g. filters, cleaning rags, replaced wear parts and unserviceable machine parts, must be disposed of separately in the interests of environmental protection.

Residual pressure is reduced only gradually. If an intervention into the hydraulic system is to be undertaken immediately after stopping, depressurize the system as described in the section "Depressurizing the Hydraulic Plant".

Screwed connections, piping, hydraulic hoses Repair any leakages in the piping and hose system immediately.

A fine, highly pressurized jet of hydraulic oil can penetrate the skin.

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

If oil has penetrated into the skin, consult a doctor immediately.

Never repair damaged piping; always replace it.

Replace hydraulic hoses immediately on detecting any damage or moist areas.

Tighten leaking screw plugs only when the system is depressurized.

Never dispose of such substances with standard household refuse.

Empty substances into the containers provided for this purpose.

Even biodegradable, "environmentally friendly" hydraulic oil has to be disposed of separately like any other oil.

Never allow oils and oily waste to get into the soil or into water: environmental hazard!

Sealing faces Individual spares may contain asbestos.

Such spares or their packaging are marked with: Never process spares containing asbestos mechanically. Inhaling asbestos dust is a health hazard.

Clean sealing faces prior to assembly.

Exhaust gases Exhaust gases are a health hazard: never inhale them.

When working on enclosed premises, draw off exhaust gases with a suction plant and ventilate the premises well.

Escaping oil is an environmental hazard.

73179376

OPERATING INSTRUCTIONS EW 220

Handling batteries

Selecting oils and greases

Batteries give off explosive gases.

Use the recommended qualitities only, matching viscosities with the temperature level.

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

Battery acid is toxic and corrosive.

Avoid any contact with the skin, mouth, eyes and clothing. Avoid spilling battery acid or inhaling the vapours.

Wear gloves, firm protective clothing and goggles when handling batteries.

If the skin is splashed with acid, rinse thoroughly with water and consult a doctor.

If the eyes are splashed with acid, rinse thoroughly with running water and consult a doctor immediately.

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 watch-straps 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.

Prior to work on the electrical system Prior to any work on the electrical system involving tools, spares etc. coming into contact with electric cables or contacts, disconnect the battery.

Filters Replace all filter elements or filter cartridges within the specified periods if cleaning is not explicity authorized.

All filters are coordinated carefully with the equipment. Original NEW HOLLAND CONSTRUCTION parts must be used to ensure smooth running and a long service life of the engine and the hydraulic units

Sealing elements When dismantling parts, watch for sealing elements.

Check sealing elements prior to installation and replace any that are even slightly damaged.

When assembling, ensure a perfect fit.

Oil-level check and oil change Position the machine horizontally.

Change the oil when the machine is at operating temperature.

Warm oil flows better and carries suspended particles (carbon or abraded matter) better.

Lubricating Clean the lubricating nipple, then lubricate as scheduled.

Disconnect first the negative pole, then the positive pole.

After work:

After servicing

Connect first the positive pole, then the negative pole.

To prevent corrosion, coat all bright metal parts with a grease film.

On completing work, reinstall all protective devices.

Never start up the drive motor while work is being done on the machine.

Carry out a performance test with the machine.

If you are not trained to carry out such work have the work performed for you by your NEW HOLLAND CONSTRUCTION dealer.

The braking system of this machine has two braking circuits. One of the circuits controls the wheels of the steered axle and the other the wheels of the rigid axle.

After performing works on the braking system during which air may have penetrated into the system (e.g. replacing a line), the braking circuit concerned must be bled after these works.

• Protect the machine against inadvertent movements.

• Connect a hose to the minimess port of a multiple-disk brake. The minimess ports are located directly beside the screwed connections of the brake pressure lines on top of the axle housing (Fig. 1).

• Stick the other end of the hose into a recipient filled with the hydraulic oil or fluid of the machine.

• Start the engine.

• Depress the brake pedal (61) until the hydraulic fluid flowing out of the minimess hose is free from bubbles.

• Repeat this procedure on the second multipledisk brake of this axle.

Tyre inflation pressure - Safety instructions

Bursting tyres and parts splintering away from the rims or from the tyre itself may cause severe injury.

Therefore, the following instructions must be observed: - Before inflating the tyre, check the tyres, rims and rim parts for damage, penetrated foreign objects and proper fitting.

- Have all damage detected repaired by a qualified workshop.

- Check the tyre inflation pressure only when the tyres are cold. After warming up, the pressures indicated are higher than usual.

- Use filling equipment with long filling hose, self-fixing nozzle and pressure gauge.

- Inflate the tyres only with compressed ambient air. Never use inflammable gases: risk of explosion.

- During tyre inflation, do not stand near the tyre and always in the plane of the tyre tread.

- Watch the tyre and the pressure gauge of the filling equipment permanently during the inflation and never exceed the prescribed tyre pressures.

- If available, place a safety cage around the wheel.

- Make sure that nobody is standing near the tyre when it is being inflated.

73179376

In case of twin-tyres: - Pay particular attention to the inner tyre flanks in case of twin-tyres. This is the place where damage may occur due to undetected foreign objects if the tyres had been fitted without intermediate rings.

- If the inner tyre of a twin-wheel was used with insufficient inflation pressure, there is the risk that parts of a multi-rim (e.g. the closing ring) are no longer in their correct positions.

In this case, check the condition of wheel and tyre particularly thoroughly before inflating the tyre. If in doubt, contact an expert.

OPERATING INSTRUCTIONS EW 220 Tyres and wheels - safety instructions

Bursting tyres and ejected parts of tyres and rims may cause severe injury.

Do not carry out works on tyres and wheels unless you have received a special training for such work.

Replace tyres with broken or worn-off treads or damaged flanks in time (or have them replaced).

Have damaged rims or rim parts repaired immediately.

2461469

When driving on public roads observe the maximum tread wear values and the correct tyre pressure.

Mount only tyres of the same size and degree of wear on both axles.

Different tyre diameters may cause damage to the differential gears.

To avoid excessive wear of tyres: - do not set off or brake abruptly, - do not take corners too fast.

Never carry out mechanical, welding or flame-cutting work on rims or rim parts of inflated tyres.

If in doubt about the safe condition of tyres, rims and rim parts, have the complete wheel checked in a qualified workshop.

Changing of tyres, rims or rim parts requires special tools and procedures. Have these works performed in a qualified workshop that is specially equipped for such work.

Always inflate tyres with the prescribed pressure: - Excessive tyre pressure leads to bad driving performance in off-road conditions and may result in tyre bursts.

- Insufficient tyre pressure results in premature wear and bad stability of the machine.

Tighten wheel nuts with a torque wrench.

After several operating hours, check with a torque wrench for tightness.

• Fit new wheels: - Inflate both tyres with a pressure of abt.

1 bar (14.5 psi).

Observe the following fitting sequence: - Inner wheel (rim with high-offset dish) - Intermediate ring (optional equipment) - Outer wheel (rim with low-offset dish). It is absolutely necessary to observe the fitting sequence, as an incorrect mounting of the wheels results in the admissible total width of the machine being exceeded.

- Observe the chapter on "Tread pattern arrangement of wheels".

- Avoid damaging the threads of wheels studs.

- Center the intermediate ring.

- Take care that there are no foreign bodies between tyre and intermediate ring.

• Tighten the wheel nuts by hand.

• Remove the support from under the lifted axle and lower the axle.

OPERATING INSTRUCTIONS EW 220 Accumulators, safety instructions 2801536

Never remove lead seals Never change rated pressure of pressure relief valves without the explicit authorization of NEW HOLLAND CONSTRUCTION. Never remove lead seals from pressure relief valves and accumulators.

After the repair work To prevent corrosion, coat all bright metal machine parts with a grease film.

On completing the work, reassemble all protective devices, covers, and soundand vibration-insulation material.

Never start up the driving motor while work is being done on the machine.

Check the repaired components and all machine functions with a trial run.

Never release the machine for recommissioning until it is fully functioning.

214

Accumulators are installed in the hydraulic system. These accumulators contain nitrogen under high initial pressure.

Wear safety goggles.

Even when the hydraulic pressure in the system is reduced, the nitrogen remains in the accumulator.

The accumulators are completely safe in operation. If incorrectly handled, however, there is a risk of explosion!

The accumulators installed in this machine should not be repaired. Defective accumulators have to be changed.

Never handle accumulator mechanically, never weld or solder it.

Prior to change the accumulator, always wear goggles and working gloves, depressurize the hydraulic part of the system.

Use only genuine NEW HOLLAND CONSTRUCTION-spare parts. In case of questions ask your NEW HOLLAND CONSTRUCTION-dealer.

Never remove or paint over warning and information plates, rating plates or type identification markings. Replace illegible or damaged plates immediately.

73179376

OPERATING INSTRUCTIONS EW 220 ENGINE

2801537

Engine, repair instructions

Read and observe: "Repair, safety instructions" and operating instructions for engine before working on engine.

Risk of injury from rotating or hot engine parts!

Switch off engine and leave to cool down.

Do repair work only if machine is secured as described in section "Securing the machine" of these operating instructions.

Assisted starting (with jump-leads) - Safety instructions

2904638

Explosion hazard Keep any potential ignition sources such as unshielded lights or burning cigarettes away from the batteries. The battery vapours are highly flammable.

Wear safety goggles.

Do not lean over the batteries when starting the machine from another vehicle.

Check and change V-belts only when engine is stationary.

Risk of injury from acid splashes and battery gases.

Repair work on the engine demands extensive know-how and special tools.

Never use assisted starting when the batteries are defective or frozen.

In case of doubt ask your NEW HOLLAND CONSTRUCTION dealer to carry out such work.

Never connect batteries (battery assemblies) unless they have the same voltage.

Use only tested jump-leads with insulated terminal clips and an adequate lead diameter.

Ensure that the bodies of the supplying and receiving machines are not in contact. Otherwise a current flow could result from connecting the positive poles. Risk of short-circuiting.

Do not assist in starting up other vehicles by supplying over-voltage e.g. from three or four batteries connected in series or from auxiliary units producing voltages higher than 24 V. Never use welding generators or welding transformers as a source of current.

Position the jump-leads in such a way that they cannot be caught by rotating engine components.

Read and observe: "Inspection and servicing, safety instructions", paying particular attention to the section "Handling batteries".

73179376

215

OPERATING INSTRUCTIONS EW 220 Assisted starting (with jump-leads)

2904639

Prior to assisted starting

Read and observe the section: "Assisted starting, safety instructions".

• Switch off all consumers at the receiving machine (empty batteries) and switch the keyoperated switch to 0.

• Switch off all consumers at the supplying machine (charged batteries) and switch off the engine.

Explosion hazard When the negative terminal is connected to ground, a strong current flows through the jumper cable. The sparks produced in the contact area can ignite the gases emanating from the discharged battery.

The negative terminal must therefore be connected to ground at a place as far away from the discharged batteries as possible.

Connecting the jumper cables Starting up the engines • Start up the engine of the supplying machine and run it at high speed.

• Start up the engine of the receiving machine. If the engine fails to start up after 15 seconds, wait for one minute and then start up again.

• After starting the engine proceed as follows:

Fig. 1

• Connect the red jumper cable to the positive pole of the empty battery (1), then to the positive pole of the charged battery (2).

• Connect the black jumper cable first to the negative terminal of the booster battery (3) and then to a bare-metal part of the machine (4).

- switch on some high-current consumers such as the complete lighting system, the fan in stage 3 and possibly also the air conditioner to prevent voltage spikes which are caused by disconnecting the jump-leads from the battery and which may damage electronic components of the vehicle.

- Observe the following working sequence for disconnecting the jump-leads: - Negative pole at receiving machine (4) - Negative pole at supplying machine (3) - Positive pole at supplying machine (2) - Positive pole at receiving machine (1) - switch the high-current consumers off again.

- Work for about half an hour mit medium engine speeds to charge up the batteries partially.

Have the electrical system of the machine checked to find out why the batteries were discharged.

OPERATING INSTRUCTIONS EW 220 Clamshell, Wear Limits

2732229

To enable the wear status to be checked, new clamshells are marked at the factory (Fig. 5): Wearing parts of the clamshell are made of high-grade alloyed steels.

When repairs are done by welding on new parts, special procedures must be observed.

- with prick-punching on the guide rail (1), - and with a chisel mark on the cylinder guide (2).

Repairs should therefore be carried out only by trained personnel with appropriate equipment.

If the natural wear on clamshell cutters and stops exceeds an admissible limit, the clamshell cylinder may be damaged. The admissible stroke of the clamshell cylinder is then exceeded, and there is an impact between piston and cylinder tube in the limit positions.

Fig. 5

The clamshell must be repaired before the marking on the cylinder guide (2) is at the same level as one of the markings on the guide rail (1).

The lower marking (1) indicates the wear on the clamshell cutters, and the top marking the wear on the clamshell stops.

OPERATING INSTRUCTIONS EW 220 TROUBLESHOOTING Instructions on troubleshooting Faults are often due to the machine not being correctly operated or serviced.

For this reason, it is vital to read through the relevant section of the operating manual once again before rectifying any faults.

If you are unable to detect the cause of the fault or rectify it, apply to the NEW HOLLAND CONSTRUCTION dealer after-sales service.

Describe the fault and all accompanying circumstances as precisely as possible. Exact data allow for fast troubleshooting.

Never do any jobs for which you are not qualified.

This fault table lists all faults which have been reported to date and outlines their possible causes and rectifying measures. In exceptional cases, a described fault may also have a different cause.

2801369

Layout of the fault table Fault The fault is described here as the outcome of an observation or a previous activity.

Therefore make careful observations.

Study the problem carefully, First think, then act.

Ask yourself the following questions: - Which warning signals preceded the fault?

- What repair and servicing work was carried out previously?

- Has this defect already occurred?

- Is it one or several simultaneously occurring faults?

Possible causes The possible causes of the observed fault are outlined in this group. They are arranged in order of probability, i.e. the possible cause occurring in most cases heads the list.

Measure This describes the troubleshooting procedure.

Section This specifies where information on troubleshooting is given in the operating manual. If there is no entry, the NEW HOLLAND CONSTRUCTION after-sales service should be consulted.

OPERATING INSTRUCTIONS EW 220 Table of fault codes The part of the electrical system used for controlling and monitoring the engine and the hydraulic system is permanently monitored by the central electronic control unit.

If a fault occurs, the working hours display (5, Fig. 1) shows a fault code and the word ERROR. The fault code is displayed alternately with the total number of hours run.

In individual cases, several faults may occur at the same time.

The corresponding fault codes are then displayed alternately with the total number of hours run (e.g: 2345 OPR. HOUR 02 ERROR 2345 OPR. HOUR 2345 100 ERROR 2345 OPR. HOUR 2345 ...).

You cannot rectify these faults yourself, as they require special testing equipment and expert knowledge.

Therefore, note the fault code and inform your nearest NEW HOLLAND CONSTRUCTION dealer.

Besides the fault code, the following information must be given to the NEW HOLLAND CONSTRUCTION specialist: - in which working situation did the fault occur?

- did the machine show a different behaviour?

- which indicator and warning lamps have lit up?

- was there any other information shown on the display?

- which were the external influences acting on the machine (such as great heat/cold, dust, permanent load over a longer period)?
