GENERAL PRECAUTIONS FOR CAB

• Before entering the cab, thoroughly remove all dirt and/ or oil from the soles of your work boots. If any controls such as a pedal is operated while with dirt and/or oil on the soles of the operator’s work boots the operator’s foot may slip off the pedal, possibly resulting in a personal accident.

• Do not leave parts and/or tools lying around the operator’s seat. Store them in their specified locations.

• Avoid storing transparent bottles in the cab. Do not attach any transparent type window decorations on the windowpanes as they may focus sunlight, possibly starting a fire.

• Refrain from listening to the radio, or using music headphones or mobile telephones in the cab while operating the machine.

• Keep all flammable objects and/or explosives away from the machine.

• After using the ashtray, always cover it to extinguish the match and/or tobacco.

• Do not leave cigarette lighters in the cab. When the temperature in the cab increases, the lighter may explode.

SAFETY

USE HANDHOLDS AND STEPS

• Falling is one of the major causes of personal injury.

• When you get on and off the machine, always face the machine and maintain a three-point contact with the steps and handrails.

• Do not use any controls as hand-holds.

• Never jump on or off the machine. Never mount or dismount a moving machine.

• Be careful of slippery conditions on platforms, steps, and handrails when leaving the machine.

008-E01A-0439

ADJUST THE OPERATOR'S SEAT

• A poorly adjusted seat for either the operator or for the work at hand may quickly fatigue the operator leading to misoperations.

• The seat should be adjusted whenever changing the operator for the machine.

• The operator should be able to fully depress the pedals and to correctly operate the control levers with his back against the seat back.

• If not, move the seat forward or backward, and check again.

• Adjust the rear view mirror position so that the best rear visibility is obtained from the operator’s seat. If the mirror is broken, immediately replace it with a new one.

009-E01A-0462

ENSURE SAFETY BEFORE RISING FROM OR LEAV-

SAFETY

BEWARE OF ASBESTOS DUST

• Take care not to inhale dust produced in the work site. Inhalation of asbestos fibers may be the cause of lung cancer.

• Depending on the wok site conditions, the risk of inhaling asbestos fiber may exist. Spray water to prevent asbestos from becoming airborne. Don’t use compressed air.

• When operating the machine in a work site where asbestos might be present, be sure to operate the machine from the upwind side and wear a mask rated to prevent the inhalation of asbestos.

• Keep bystanders out of the work site during operation.

• Asbestos might be present in imitation parts. Use only genuine Hitachi Parts.

PREVENT BATTERY EXPLOSIONS

• Battery gas can explode.

• Keep sparks, lighted matches, and flame away from the top of battery.

• Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer.

• Do not charge a frozen battery; it may explode. Warm the battery to 16˚C ( 60˚ F ) first.

• Do not continue to use or charge the battery when electrolyte level is lower than specified. Explosion of the battery may result.

• Loose terminals may produce sparks. Securely tighten all terminals.

• Battery electrolyte is poisonous. If the battery should explode, battery electrolyte may be splashed into eyes, possibly resulting in blindness.

• Be sure to wear eye protection when checking electrolyte specific gravity.

512-E01B-0032

SERVICE AIR CONDITIONING SYSTEM SAFELY

• If spilled onto skin, refrigerant may cause a cold contact burn.

• Refer to the instructions discribed on the container for proper use when handling the refrigerant.

• Use a recovery and recycling system to avoid leaking refrigerant into the atmosphere.

• Never touch the refrigerant.

SAFETY

HANDLE CHEMICAL PRODUCTS SAFELY

• Direct exposure to hazardous chemicals can cause serious injury. Potentially hazardous chemicals used with your machine include such items as lubricants, coolants, paints, and adhesives.

• A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques.

• Check the MSDS before you start any job using a hazardous chemical. That way you will know exactly what the risks are and how to do the job safely. Then follow procedures and use recommended equipment.

• See your authorized dealer for MSDS’s (available only in

English) on chemical products used with your machine.

515-E01A-0309

DISPOSE OF WASTE PROPERLY

• Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used with

HITACHI equipment includes such items as oil, fuel, coolant, brake fluid, filters, and batteries.

• Use leakproof containers when draining fluids. 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 center to recover and recycle used air conditioning refrigerants.

• Inquire on the proper way to recycle or dispose of waste from your local environmental or recycling center, or from your authorized dealer.

TIPS FOR OPTIMAL AIR CONDITIONER USAGE

For Rapid Cooling

Temperature in the cab may rise over 80°C (176°F) when the machine is exposed to sun light in the summer.

In this case, ventilate air in the cab first by opening the windows for rapid cooling. After starting the engine, press

AUTO switch (9). Set temperature to 「18.0」 on LCD (7) using temperature control switch (11). Turn circulation mode switch (12) ON.

When Windows Become Clouded

If the insides of the windows become clouded during rainy weather or on humid days, operate the air conditioner to aid in keeping the windows clear. When the atmosphere is very damp, and if the air conditioner has run excessively, the outside of the windows may become clouded. If this happens, turn off the air conditioner to adjust the temperature in the cab.

Off-Season Air Conditioner Maintenance

To protect each part of the compressor from a lack of lubricant, operate the air conditioner at least once a month for several minutes with the engine running at a slow speed during off-season. When the cab temperature is lower than

15°C (59°F), the air conditioner may not operate. If this happens, warm the cab using the heater first.

IMPORTANT:

•

Do not suddenly increase the engine speed.

•

Refer to the item “Check Air Conditioner

Filter” in the Maintenance Section for maintenance of the air conditioner filters.

•

Always clean the auto air conditioner sensor for effective air conditioner performance. Avoid placing any obstructions around the sensor.

Warming-up the Motor and the Cylinders

IMPORTANT: • In cold weather, be sure to thoroughly warm-up the motors and cylinders.

• If the hydraulic circuit is continuously relieved for a certain amount of time, the temperature in the control valve would rise excessively. Never operate to stroke end more than 15 seconds. After relieving any function, up to 15 seconds, be sure to have a 5–10 second intermission.

1. Check that the needle of coolant temperature gauge (2) starts moving so that engine coolant warm-up operation is complete.

2. Turn engine control dial (1) to the medium position.

3. Operate the boom, arm and bucket cylinders slowly to each stroke end several times.

4. Operate travel and swing functions slowly, initially moving only short distances.

5. Continue to repeat steps 3 and 4 until bucket cycle time is normal.

AUTO-IDLE

With auto-idle selector (3) turned to the A/I ON position, approximately 4 seconds after all control levers are returned to neutral, the engine speed decreases to the auto-idle setting to save fuel consumption. The engine speed will immediately increase to the speed set by engine control dial (2) when any control lever is operated.

IMPORTANT: • Always check if auto-idle indicator (1) is turned on or off before starting operation.

If the indicator is on, the auto-idle function will be activated.

• Always be aware of engine control dial setting when auto-idle selector (1) turned to the A/I ON position. If the engine speed is set high with engine control dial (2), and if the operator is not aware of the high engine speed setting, the engine speed will unexpectedly increase when any control lever is operated, causing unexpected machine movement, thus possibly resulting in serious personal injury.

WARNING: Prevent the machine from unexpected movement. Be sure to turn off auto-idle selector (3) when unexpected machine movement is undesirable, especially when loading/unloading the machine for transportation.

Note that auto-idle function can be turned on or off only when the key switch is in ON position. Always check if the auto-idle function is turned on or off with auto-idle indicator (1).

Auto-Idle Function ON :

Auto-Idle Function OFF :

POWER MODE

One of three engine speed modes, E, P or H/P mode, can be selected using power mode switch (1).

• E (Economy) Mode

Even if the engine speed is reduced in the E mode, digging force remains unchanged from that in the P mode. Although production is reduced slightly more than in the P mode, the fuel consumption and noise levels are reduced, allowing the machine to operate most efficiently.

• P Mode

Operate the machine in this mode when performing normal work.

• H/P (High Power) Mode

WARNING: In the H/P mode, the engine speed will change quickly. To ensure safety, be sure to turn power mode switch (1) to the P or E mode position before starting such works as loading the machine on or off a trailer or lifting a load with the front attachment, which may result in personal accidents if the engine speed is suddenly changed.

When rolling in the arm while digging deep trenches for example, more power may be required. In such cases, use the H/P mode. The maximum power of the machine can be utilized in this mode, increasing work efficiency when more power is required than in the P mode.

The H/P mode is activated and the engine speed is increased when the boom raise or the arm rolled-in operation is made with the engine fast idle speed set at faster than approx. 1650 min

OPERATING BACKHOE

1. Place the bucket teeth on the ground with the bottom of the bucket at a 45 degree angle to the ground.

2. Pull the bucket toward the machine using the arm as the main digging force.

3. When soil sticks to the bucket, remove it by moving the arm and/or bucket rapidly back and forth.

4. When trenching a straight line, position the tracks parallel to the trench. After digging to the desired depth, move the machine as required to continue the trench.

IMPORTANT: When lowering the boom, avoid sudden stops that may cause shock load damage to the machine.

When operating the arm, avoid bottoming the cylinder to prevent cylinder damage.

When digging at an angle, avoid striking the tracks with the bucket teeth.

When digging a deep excavation, avoid striking the boom or bucket cylinder hoses against the ground.

GRADING OPERATION

IMPORTANT: Do not pull or push dirt with the bucket when traveling.

Select grading mode when finishing work is required.

Position the arm slightly forward of the vertical position with bucket rolled back, as shown.

Operate arm roll-in function while slowly raising the boom.

Once the arm moves past, the vertical position slowly lower the boom to allow the bucket to maintain a smooth surface.

Grading operation can be more precisely done by operating the boom, arm and bucket simultaneously.

OPERATING TIPS

Do not hit the track with the bucket when digging.

Whenever possible, position your machine on a level surface.

Do not use the bucket as a hammer or pile driver. Do not attempt to shift rocks and break walls using swing motion.

IMPORTANT: To avoid damaging cylinders, do not strike the ground with the bucket nor use the bucket for tamping with the bucket cylinder fully extended (the bucket completely curled under).

Adjust the length and depth of each cut to produce a full bucket with every pass.

Full loads on every pass is more productive than a faster cycle with a partially filled bucket.

Full load should be the first objective, followed by speed, to increase productivity.

IMPORTANT: Do not attempt to break ledge rock by extending the arm to maximum reach and dropping the front of the bucket on the bucket teeth for penetration. Serious damage to the machine can result.

Once the trench is open, ledge rock can be broken by pulling the bucket up under the layers. The top layers are pulled out first, with one or two layers being lifted at a time.

Do not side load the bucket. For example, do not swing the bucket to level material or do not strike objects from the side with the bucket.

SELECT CORRECT TRACK SHOES

IMPORTANT: Using wide track shoes on rough ground may result in shoe bending and/or loosening, and may damage other undercarriage components.

Never use wide track shoes on rough ground such as rocks, sand or gravel. Wide track shoes are designed for soft ground.

Track shoe bolts should be checked periodically for tightness.

HYDRAULIC BREAKER AND HYDRAULIC CRUSHER

Select a breaker or crusher that is the correct size and weight for your machine. See your authorized dealer for correct breaker information.

Carefully study the operation manuals of the machine, breaker and crusher, and perform the required checks and/or inspection before connecting the breaker or the crusher to the arm.

IMPORTANT: Precautions for connecting breaker or crusher piping.

• Do not allow impurities to enter into the system when

switching the breaker or the crusher with the bucket.

• When the breaker or crusher is not used, apply the

cover to the pipe opening on the arm top and install the plug into the hose end of the breaker or the crusher to prevent impurities from entering the system.

Be sure to provide spare covers and plugs in the tool box so that they will be available when needed.

• After connecting, check the connecting seal fitting for

oil leakage, and pipe clamp bolts for looseness.

SECONDARY RELIEF PRESSURE ADJUSTMENT

When attaching the breaker other than the NPK, it is necessary to install the secondary relief valve in line. For this purpose, the boom piping for the attachment is provided with a part to which the secondary relief valve is connected.

Pressure is set to A when shipped from HITACHI.

Model

ZX270 Class

ZX330 Class

Set Pressure A

17.6MPa (180 kgf/cm)

19.6MPa (200 kgf/cm)

After completing piping, reset this pressure to the specified level of each breaker.

Two methods are available to measure the pressure.

Measure the pressure as follows.

1. Measuring the pressure at the relief valve :

(1) Attach a pressure gauge to the pressure gauge connection port (see the figure below)

(2) Close the stop valves at the arm end. Depress the attachment pedal to pressure the line.

(3) Adjust the pressure to 1 to 1.5MPa (10 to 15 kgf/cm

2

) higher the setting pressure.

Adjust the pressure as follows :

1. Attach the pressure gauge to the pressure gauge port.

2. Loosen the lock nut, then gradually turn the pressureadjust screw clockwise to increase the pressure, or counterclockwise to reduce the pressure.

One turn of the screw changes about 4.9MPa (50 kgf/ cm2) in pressure.

3. After adjusting the pressure, make sure to tighten the lock nut.

PRECAUTIONS FOR BREAKER OPERATION

WARNING: Machine stability is reduced as the breaker is much heavier than the bucket.

When using a breaker, the machine is more apt to tip over. Also, flying objects may hit the cab or other part of the machine. Observe the following precautions and take any other precautions necessary to prevent accidents and machine damage from occurring.

• Avoid hitting objects with breaker.

The breaker is heavier than the bucket, causing the breaker to lower faster.

Take care not to hit any objects with breaker. Doing so will result in damage to the breaker, the front attachment, and/or the upperstructure. Always move (lower) the breaker slowly to position the tip of the chisel on the object to be broken before starting breaker operation.

• Do not use the breaker and/or the swing function to move objects. Damage to the boom, arm, and/or breaker may result.

• Do not operate the breaker continuously longer than one minute. Excessive chisel wear will result. If an object could not be broken within one minute, apply the chisel to other locations, less than one minute for each location.

• Raising the front part of the undercarriage by pressing down the breaker may cause damage to the front attachment. Although raising the front edge of the undercarriage up to 150 mm (6 in) is tolerable, do not practice this method more than necessary. Never raise the front edge of the undercarriage higher than 150 mm (6 in) by pressing the breaker down.

BREAKER MAINTENANCE

Change Hydraulic Oil and Replace Hydraulic Oil Tank Filter

Hydraulic breaker operation subjects the hydraulic system to become contaminated faster and to quickly deteriorate the hydraulic oil. For this reason, hydraulic oil must be changed and the hydraulic oil tank filter must be replaced more often than the machine equipped with a bucket. Failure to do so may result in damage to the breaker, hydraulic oil pump, and other related hydraulic system components. Recommended changing intervals are shown below. (For filter replacement and oil changing intervals are shown below.(For filter replacement and oil changing procedures, refer to the

PRECAUTIONS FOR CRUSHER OPERATION

Prevent machine tipping over and damage to the front attachment. Observe the following precautions for crusher operation.

WARNING: Machine stability is reduced as crusher is much heavier than bucket.

When operating with a crusher, the machine is more apt to tip over. Also, falling or flying objects may hit the cab or other part of the machine. Observe the following precautions and take any other precautions necessary to prevent accidents and machine damage from occurring.

• Do not allow the machine’s weight to be supported by the crusher or bucket cylinder with the bucket cylinder fully extended or retracted. Doing so may damage the front attachment. In particular, avoid doing so with the bucket cylinder fully extended, as the front attachment will be easily damaged.

Take care to prevent this from happening when dismantling foundation structures using the crusher.

• Using the front attachment, don’t raise the base machine off the ground with the arm cylinder fully extended. Failure to do so may result in damage to the arm cylinder.

• When a heavyweight attachment such as a crusher is installed, avoid quickly starting or stopping the front attachment. Failure to do so may result in damage to the front attachment.

• Do not attempt to perform crushing on either side of the machine. Always perform crushing operations to the fore or rear, parallel with the tracks. Otherwise, tipping over may occur.

• Operate the hydraulic excavator carefully to avoid hitting the boom, and cab.

5-21


When operating the crusher up high with the boom fully raised, be careful of falling objects.

WRONG

• When operating the crusher on a floor in a building, first confirm that the floor has sufficient strength to support the load caused by crushing, in addition to the machine weight.

• Always operate the crusher on a stable, level surface, not on a slope or on crushed scraps.

• Do not use the crusher to haul or load crushed scraps.

• If a multiple number of attachments, such as crusher and bucket, or crusher and breaker, are used, replacing them with each other at intervals, impurities are more apt to enter the hydraulic system and the hydraulic oil deteriorates quickly. For this reason, replace the hydraulic oil tank filter and change the hydraulic oil at the intervals specified in the breaker time sharing diagram in the previous section.

Read the breaker time sharing diagram supposing that time sharing percentage of attachment (s) other than the crusher is that of the breaker.

• Always remove the crusher from the excavator before transporting the machine. Do not fully extend the bucket cylinder when transporting, as this may damage the front attachment, when vibrations arise during transportation.

ATTACHMENT

Allowable Weight Limits of Installed Attachment

• When an attachment other than the standard bucket is installed on the machine, the machine stability will be different. If a heavy attachment is used, not only will controllability be affected but also machine stability will be reduced, possibly causing safety hazard.

• Before installing attachments such as hydraulic breaker, crusher (concrete crusher), or pulverizer, take machine controllability into account when selecting the weight of the attachment by referring to the table below.

• Breaker operation speed is faster than crusher operation so that the recommended breaker max. weights are reduced more than those of the crushers.

• The weight is not the only factor to be considered when selecting a breaker. Select proper manufacturers’ breaker models while referring to the table on the next page.

• Avoid installing an attachment with a long overall length.

Damage to the front attachment may result.

• When an attachment of the max. weight is installed, always operate the attachment over the front or rear side of the machine. In addition, avoid operating the attachment at the maximum reach.

• Crushers are heavier than breakers. Slowly move the control lever when operating a crusher.

5-24


Attachments

Example commercial attachment models (breakers and crushers) for excavators are shown in the following table. Among the crusher models, some models are heavier than the recommended weight on the previous page. Before installing them, sufficiently coordinate with the attachment manufacture.

Always contact your nearest HITACHI dealer before installing attachments shown with this mark *.

When the machine is operated with an attachment other than bucket, generally heavier loads are applied to the base machine comparing with bucket only operation. Therefore, unless the machine is properly operated, damage not only the attachment but to the base machine may result. Thoroughly read and understand the base machine operator’s manual and the attachment manual to prevent accidents.

D. HYDRAULIC SYSTEM

INSPECTION AND MAINTENANCE OF HYDRAULIC

EQUIPMENT

CAUTION: During operation, the parts of the hydraulic system become very hot.

Allow the machine to cool down before beginning inspection or maintenance.

1. Be sure that the machine is parked on a level, firm surface before servicing hydraulic equipment.

2. Lower the bucket to the ground and stop the engine.

3. Begin servicing hydraulic components only after components, hydraulic oil and lubricants are completely cooled, and after releasing residual pressure.

3.1 Bleed air from the hydraulic oil tank to release internal pressure.

3.2 Allow the machine to cool down.

Note that servicing heated and pressurized hydraulic components may cause hot parts and/or oil to fly off or escape suddenly, possibly resulting in personal injury.

3.3 Keep body parts and face away from plugs or screws when removing them.

Hydraulic components may be pressurized even when cooled.

3.4 Never attempt to service or inspect the travel and swing motor circuits on slopes. They are highly pressurized due to self-weight.

4. When connecting hydraulic hoses and pipes, take special care to keep seal surfaces free from dirt and to avoid damaging them. Keep these precautions in mind:

4.1 Wash hoses, pipes, and the tank interior with a washing liquid and thoroughly wipe it out before reconnecting them.

4.2 Only use O-rings that are free of damage or defects. Be careful not to damage them during reassembly.

4.3 Do not allow high pressure hoses to twist when connecting them. The life of twisted hoses will be shortened considerably.

4.4 Carefully tighten low pressure hose clamps.

Do not overtighten them.

7-25

MAINTENANCE

5. When adding hydraulic oil, always use the same brand of oil; do not mix brands of oil. As the machine is filled with

Super EX 46HN when it is shipped from the factory, use it as a general rule. When selecting to use another brand of oil listed in the table “Brand names of recommended hydraulic oil”, be sure to completely replace the oil in the system.

6. Do not use hydraulic oils other than those listed in the table “Brand names of recommended hydraulic oil”.

7. Never run the engine without oil in the hydraulic oil tank.

7-26

MAINTENANCE

BREAKER MAINTENANCE

Change Hydraulic Oil and Replace Hydraulic Oil Tank Filter

Hydraulic breaker operation subjects the hydraulic system to become contaminated faster and to quickly deteriorate the hydraulic oil. For this reason, hydraulic oil must be changed and the hydraulic oil tank filter must be replaced more often than the machine equipped with a bucket. Failure to do so may result in damage to the breaker, hydraulic oil pump, and other related hydraulic system components. Recommended changing intervals are shown below. (For filter replacement and oil changing intervals are shown below.(For filter replacement and oil changing procedures, refer to the

“Hydraulic System” in the “MAINTENANCE” Section.)

IMPORTANT: Improper radio communication equipment and associated parts, and/or improper installation of radio communication equipment effects the machine's electronic parts, causing involuntary movement of the machine.

Also, improper installation of electrical equipment’s may cause machine failure and/ or a fire on the machine.

Be sure to consult your authorized dealer when installing a radio communication equipment or additional electrical parts, or when replacing electrical parts.

Never attempt to disassemble or modify the electrical/electronic components. If replacement or modification of such components is required, contact your authorized dealer.

Batteries

CAUTION: Battery gas can explode. Keep sparks and flames away from batteries. Use a flashlight to check the battery electrolyte level.

Do not continue to use or charge the battery when electrolyte level is lower than specified. Explosion of the battery may result.

Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into the eyes.

Avoid hazard by:

1. Filling batteries in a well-ventilated area.

2. Wearing eye protection and rubber gloves.

3. Avoiding breathing fumes when electrolyte is added.

4. Avoiding spilling or dripping electrolyte.

5. Using proper booster battery starting procedures.

If you spill acid on yourself:

1. Flush your skin with water.

2. Apply baking soda or lime to help neutralize the acid.

3. If splashed in eyes, flush with water for 10 to 15 minutes. Get medical attention immediately.

MAINTENANCE

Electrolyte Level Check --- every one month

1. Check the electrolyte level at least once a month.

2. Park the machine on level ground and stop the engine.

3. Check the electrolyte level.

3.1 When checking the level from the battery side:

Clean around the level check lines with a wet towel.

Don’t use a dry towel. Static electricity may be developed, causing the battery gas to explode. Check if the electrolyte level is between U.L (Upper Level) and L.L

(Lower Level). In case the electrolyte level is lower than the middle level between the U.L and L.L, immediately refill distilled water or commercial battery fluid. Be sure to refill with distilled water before recharging (operating the machine). After refilling, securely tighten the filler plug.

3.2 When impossible to check the level from the battery side or no level check mark is indicated on the side:

After removing the filler plug from the top of the battery. Check the electrolyte level by viewing through the filler port. It is difficult to judge the accurate electrolyte level in this case. Therefore, when the electrolyte level is flush with the U.L, the level is judged to be proper. Then, referring to the right illustrations, check the level. When the electrolyte level is lower than the bottom end of the sleeve, refill with distilled water or commercial battery fluid up to the bottom end of the sleeve. Be sure to refill with distilled water before recharging (operating the machine). After refilling, securely tighten the filler plug.

3.3 When an indicator is available to check the level, follow its check result.

4. Always keep around the battery terminals clean to prevent battery discharge. Check terminals for loose and/or rust. Coat terminals with grease or petroleum jelly to prevent corrosion build up.

Loosen the Track

CAUTION: Do not loosen valve (1) quickly or loosen it too much as high-pressure grease in the adjusting cylinder may spout out. Loosen carefully, keeping body parts and face away from valve (1).

Never loosen grease fitting (2).

IMPORTANT: When gravel or mud is packed between sprockets and track links, remove it before loosening.

1. To loosen the track, slowly turn valve (1) counterclockwise using long socket 24; grease will escape from the grease outlet.

2. Between 1 to 1.5 turns of valve (1) is sufficient to loosen the track.

3. If grease does not drain smoothly, slowly rotate the raised track.

4. When proper track sag is obtained, turn valve (1) clockwise and tighten to 90 N•m (9.2 kgf•m, 67 lbf•ft).

4. Dry the filters.

Rear Side of Cab

Installation

When installing the cleaned recirculation and/or ventilation filter or new filters, follow the reverse order of the Removing

Filter procedures described on the front page.

• Ventilation Filter

Use attention when installing the filter so that the notch faces the back of the cab and the stamped arrows face the air conditioner unit. After installing the filter, install the upper cover while aligning it with the duct.

• Recirculation Filter

While contacting the attached filter plate onto the duct, install the filter so that the clips align with the duct mounting holes.

MAINTENANCE

10 Check the Air Conditioner --- daily

1. Check pipe connections for refrigerant gas leakage.

If oil seepage is found around pipe connections, as illustrated, it indicates possible gas leakage.

2. Check refrigerant quantity.

After running the engine at 1500 min

–1

(rpm) for 2 to 3 minutes, check refrigerant quantity through the sight glass (2) on the receiver tank (1).

3. Check the condenser.

If the condenser fins become clogged with dirt or insects, the cooling effect will be decreased. Be sure to keep it clean at all times.(Refer to “Clean Radiator Core” in Maintenance Section.)

4. Check the compressor

After operating the air conditioner for 5 to 10 minutes, touch the high-pressure side and low-pressure side pipes with your hand. If normal, the high-pressure side pipe will be hot, and the low-pressure side cold.

5. Check mounting bolts for looseness.

Confirm that the compressor mounting bolts and other mounting/fastening bolts are securely tightened.

6. Inspect belt, check and adjust tension.

Visually check the compressor and fan belts for wear.

Check and adjust belt tension, referring to the illustration

(right).

If any abnormalities are found in air conditioner operation, see your authorized dealer for inspection.

MAINTENANCE

Adjust Compressor Belt Tension

Visually check the belt for wear. Replace if necessary. Check compressor belt tension by depressing the midpoint between compressor pulley and crank pulley with the thumb. Deflection must be 9 to 12 mm (0.35 to 0.47 in) with a depressing force of approximately 98 N (10 kgf, 22 lbf).

If tension is not within specifications, loosen bolt (1). Move the tension pulley by bolt (2) until tension is correct. Tighten bolt

(1).

NOTE: When a new belt is installed, be sure to re-adjust the tension after operating the engine for 3 to 5 minutes at slow idle speed to be sure that the new belt is seated correctly.

11 Clean Cab Floor --- as necessary

IMPORTANT: When cleaning the cab floor with tap water, spray the floor only. Take care not to splash the surrounding area. Don’t increase water spray speed by restricting the hose end, and don’t use high pressure steam for cleaning.

Be sure to completely remove any moisture from the surrounding area.

1. Park the machine on solid and level surface. Lower the bucket to the ground. Before cleaning, stop the engine.

2. Sweep the cab floor clean using a brush, and brush dust from the cab floor while spraying water.

3. When cleaning the floor mat, sweep dust (water) along the grooves on the floor mat.

4. When cleaning after removing the floor mat, sweep dust

(water) through two cleaning holes.

CAUTION: If fixing bolts for counterweight are loosened, consult your nearest authorized dealer.

IMPORTANT: Make sure bolt and nut threads are clean before installing.

Apply lubricant (e. g. white zinc B solved into spindle oil) to bolts and nuts to stabilize their friction coefficient.

NOTE: Tightening torque required is shown in N•m.

For example, when tightening a bolt or nut with a wrench of 1 m length, turning the end of it with a force of 120 N, the torque produced will be:

1 m ×120 N = 120 N•m

To produce the same torque with a wrench of 0.25 m:

0.25 m × N = 120 N•m

Necessary force will be:

120 N•m ÷ 0.25 m = 480 N

LIFTING HOOK

Handling suspended loads

This machine was specifically designed for excavation/loading application. Handling suspended loads, as a completion of excavation/loading application, is admitted on condition that the machine is equipped with the specific device supplied by

HITACHI Construction Machinery on request. For handling suspended loads strictly follow the national laws on this subject, the rules indicated below.

WARNING: Load holding and lowering pilot operated valves located on cylinders, overload warning device, the lifting capacity chart in the cabin and hook on the

“A” link are SAFTY DEVICES being part of the version for suspended load handling. If one of these devices is missing or damaged, the machine cannot be used for handling suspended loads.

WARNING: Before handling suspended loads, check that valves are not damaged or unusually noisy. If any defect is discovered, contact your dealer and do not use the machine for handling suspended loads. Lifting devices (hooks, chains, etc) must be undamaged and not worn. Check before use. Follow the current laws to check these devices. (they are not supplied with the machine)

WARNING: To avoid any possible accident, do not exceed the machine’s rated lifting capacity. If the machine is not on level ground, lifting capacity is reduced. Set the engine power suitable for the required hydraulic power. Estimate (if not known) the weight of the object to handle and compare with the data on the lifting chart in the cabin. Do not lift loads whose weight exceeds the maximum load on the chart. Before starting lifting operations, press switch (1) to engage the overload warning device sensor. When reaching the limit load the sensor activates an acoustic device. Fix the load by the special hook (2) on the

“A” link , by using coupling devices and chains suitable for the load to lift.

WARNING: Lifting devices (hooks, chains, etc) must be undamaged and not worn: check them. Follow the current laws to check these devices (they are not supplied with machine). Do not lift objects fixed to the ground. Do not use this device to tow, uproot or tear out. In order to limit load oscillations, do not use too long ropes and/or chains to sling it. Check the working area and be sure there are no obstacles on the load run. To avoid sudden load oscillations, lift the load slowly and avoid any sharp movement. Keep the load close to the machine to improve stability and operate preferably on its longitudinal axis rather than its transversal axis. Lift the load to the bare minimum.

WARNING: Lifted loads can oscillate or rotate in any direction: it is possible that they hit persons or the machine’s cabin. Keep everybody away from the machine range and handle the load slowly in order to avoid danger. If the load starts oscillating or rotating, slacken and stop, place it carefully on firm ground and correct the way it was hooked up.

13-16


LIFTING CAPACITIES

NOTE: 1. Lifting capacity of the ZX series does not exceed

75% of tipping load with the machine on firm, level ground or 87 % of full hydraulic capacity. (ISO

10567)

2. * Indicates load limited by hydraulic capacity.
