OPERATION IN EXTREME COLD

5. If the machine becomes overheated, idle the machine to help cool the engine, turn engine OFF and check coolant level. If after filling to proper level the machine continues to overheat, stop engine, allow to cool, drain and flush entire cooling system and refill with the proper mixture of fresh, clean coolant.

1. Follow procedures at the beginning of this chapter as starting the engine may be difficult due to extremely cold temperature.

2. Use an engine oil, hydraulic oil, and diesel fuel d e s i g n e d fo r u s e i n c o l d c l i m a t e s . S e e Maintenance Section for reference. Keep batteries fully charged.

3. Make certain to perform machine warm-up procedures as described at the beginning of this chapter to prevent premature wear or damage to pumps, motors, and other components.

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

WARNING Do not drain the cooling system when the engine is hot. Allow time to cool all engine parts. Failure to comply could result in death or serious injury B121

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

7. Keep a close watch on the gauges for warning icons during operation. Avoid unnecessary low speed running of the engine during operation.

OPERATION IN HIGH ALTITUDES

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

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

NOTICE: Mix coolant to a protection temperature of 5°C (9°F) lower than the machine may experience during operation, storage or transport.

2. Keep close watch on the engine temperature gauge to avoid overheating of the engine.

5. Keep battery terminals free of ice and snow. Ice and snow could cause the terminals to short circuit and cause extensive damage to the machine system. Check the battery electrolyte (acid) level frequently and fill as necessary with distilled water. If the machine will be left outside overnight, removing the batteries and storing in a warm area is recommended.

OPERATION IN EXTREME HEAT

OPERATION IN SANDY AND DUSTY AREAS 1. Check the engine air cleaner elements frequently in sandy or dusty conditions.

2. When air cleaner restriction lamp illuminates, change filters immediately regardless of time intervals.

3. Service fuel filter, water separator, engine oil and filters, and all hydraulic filters frequently.

4. Keep the radiator, oil cooler, inter-cooler, and air conditioning condenser clean.

1. Use an engine oil, hydraulic oil and fuel designed for use in hot climates. See Maintenance Section for reference. Also keep batteries fully charged.

2. Operate the A/C with the cab doors and windows closed.

LONGER UNDERCARRIAGE LIFE

BUCKET SELECTION GUIDE Bucke t se lection is extremely impo r tant to a machine’s productivity, durability, and stability.

Choosing an excessively large bucket can reduce productivity due to slower than normal cycle times.

Using an oversized or overly wide bucket in severe conditions such as mining, will lead to durability problems for both the machine and bucket involved.

Undercarriage life varies upon the operation method.

Use the following guides to increase the life of the machine’s undercarriage.

Stability will be adversely affected using a bucket that is unnecessarily large.

1. Select the track shoe that best suits the machine’s application. If in doubt, consult with your dealer when selecting track shoes.

If the buckets used locally var y in weight from recommended buckets, it will be necessary to adjust the bucket capacity accordingly. A heavier bucket must correspond to a reduced capacity.

2. Do not allow the tracks to slip during operation. If this occurs, reduce load until slipping stops.

3. Avoid sudden starts, accelerations, abrupt speed changes, high speeds on rough terrains, sharp turns, and sudden stops.

4. Always operate machine in straight lines whenever possible. Avoid short radius when turning. Make turns with the largest possible radius.

5. Prior to operation, clear boulders and obstacles to prevent damage to track shoes.

6. Always operate machine parallel to the incline of the slope. Operating machine across the incline of the slope will not only shorten the machine’s undercarr iage life, but the machine could unexpectedly slide down hill, and/or roll over.

If the material density (weight) exceeds guidelines specifications then the bucket capacity must be reduced.

If the machine is to continuously dig rock, wasted shale, river cobble or other severe applications the narrowest bucket possible should be utilized. This will allow the greatest possible penetration and minimal twisting of the attachment (boom and arm). Bucket capacity is not to be the prime consideration for severe applications.

If a machine is used in a spoil pile operation, which causes a large radius dump cycle, applicable loads may have to be adjusted down by 5% from the Lift Chart Values.

USE OF OPTIONAL ATTACHMENTS

8. It is very important that inspections and maintenance schedules be followed as indicated in the Maintenance Section. Work conditions may require these scheduled times to be significantly shorter.

If a machine is equipped with optional attachments, applicable bucket sizes and suspended loads must be reduced in direct proportion to the weight or combined weight of these attachments. Failure to consider the added weight of such attachments will cause stability problems. Additionally the weights of such attachments must be considered when the Lift Chart is referred to before lifting a load.

9. DO NOT OPERATE machine with loose track shoes, and maintain proper track tension adjustment at all times during operation.

NOTICE: The operator must consider the weight of any device utilized for lifting to properly calculate the total lifting capacity of the machine.

7. Do not force the machine to carry out work that exceeds its working capability.

CHAPTER 4 - OPERATING INSTRUCTIONS GETTING THE MOST OUT OF YOUR BREAKER

WARNING Do not attempt to operate or service this machine unless you have first read and perfectly understood the safety messages and instructions appearing in this manual. Failure to comply could result in death or serious injury.

M1087

A. BREAKER PROPER POSITIONING

DC03M065

Figure 53

Always position the breaker perpendicular to the material you intend to break. The breaker can be vertical, horizontal, or anywhere in between, as long as the tool is perpendicular to the surface and the pressure applied is in the same direction of the tool.

B. APPLIED PRESSURE ON BREAKER The breaker must have sufficient pressure between the tool and the surface of the material intended to break in order to allow the shock wave to flow through the tool and to the material being broken.

The applied pressure has to be constantly adjusted by combining the boom, arm, and bucket functions so that the breaker follows the tool at all times during breaker operation.

4-30

When the excavator boom is lowered, it normally follows a curved path, which changes the original perpendicular position of the breaker. It is very important to keep adjusting the operator’s controls to maintain constant perpendicularity between the breaker and the surface of the material being broken.

In addition, the applied pressure should be sufficient to avoid the breaker tool from bouncing on the rock rather than transmitting the shock wave into it. The applied pressure should not lift the machine high off the ground, since the excavator can drop suddenly, as the breaker breaks through the material, and harmful shock loads will be transmitted through the entire machine.

CHAPTER 4 - OPERATING INSTRUCTIONS E. EXCAVATING AND TRENCHING

C. BREAKING OVERSIZE ROCKS

DC03M068 DC03M066

Figure 54

Do not attempt breaking oversize boulders from the center. It is much more efficient to break these type of rocks from the edges. Also, do not break into smaller pieces than necessary. There is a direct relationship between the size of the boulders and the size of the breaker. It is inefficient to break large rocks with small breakers and vice versa.

D. SURFACE ROCK DEMOLITION

Figure 56

Lay back side walls a bit at the time so that they do not interfere with the breaker housing. To lessen the opportunity for side loading, approach each wall from the opposite side by positioning the excavator perpendicular to the trench.

F. RULES TO REMEMBER Use the following rules for correct breaker operation: 1. Make sure to adjust the proper hydraulic flow according to the breaker specifications.

2. Place tool against material to be broken at 90° angle to work surface.

3. Use the boom, arm, and bucket controls to press firmly against surface, keeping perpendicularity while operating the breaker.

4. As material breaks, stop breaker quickly to prevent idle strokes.

5. Reposition breaker if material does not break after 15 seconds of operation.

DC03M067

Figure 55

Use the breaker just as if it were a hand held breaker, or a plain hammer and chisel. Adjust the breaker’s position according to the work to be done, and take small bites at a time. The only difference between a hand held breaker and the hydraulic excavator breaker is the size of the rocks that can be broken.

Do not try to break too much at one time.

6. Do not bend or pry with the breaker tool while operating.

7. DO NOT OPERATE breaker with attachment cylinders at full extension.

8. DO NOT OPERATE breaker submerged in water.

9. DO NOT OPERATE breaker for more than a minute at a time.

10. Lubricate breaker every 30 minutes. Keep tool lubricated at all times.

CHAPTER 5 - LUBRICATION, FILTERS, AND FLUIDS BIODIESEL FUEL Fatty Acid Methyl Ester Biodiesel (Biodiesel Fuel) consists of a family of fuels derived from vegetable oils treated with methyl esters.

NOTICE: Biodiesel fuel blends are approved for your engine only if they comply with Specification Standards EN 14214 or ASTM D6751. Do not use biodiesel unless it is approved for your engine.

Check with your authorized dealer for information.

It is imperative that you check which blend is approved for your engine with your local dealer.

Beware that the use of Biodiesel fuel that does not comply with the Standards EN14214 or ASTM D6751 could lead to severe damage to the engine and fuel system of your machine. The use of fuels that are not approved may void warranty coverage.

Biodiesel Fuel Usage Conditions NOTICE: The Biodiesel Fuel must meet the fuel specification mentioned above.

Biodiesel fuel must be purchased from a trusted supplier that understands the product and maintains good fuel quality. Biodiesel fuel must be pre-blended by the supplier. Mixing Biodiesel fuels on site can result in an incorrect mixture which can lead to problems with both engine and fuel system.

Engine perfor mance is effected by the use of biodiesel fuel. There may be up to 12 percent reduction in power or torque depending on the blend used.

NOTICE: DO NOT modify the engine and/or fuel injection pump settings to recover reduced performance.

The reduced power must be accepted if using any biodiesel fuel blend.

Some modification may be required to allow the engine to use biodiesel fuel. Consult your dealer for c o m p l e t e i n fo r m a t i o n r e g a r d i n g a p p r o v e d modifications.

Biodiesel has a higher cloud point than diesel fuel.

NOTICE: The use of high biodiesel fuel blends is not recommended in cold weather conditions.

With biodiesel fuels, it may be necessary to change engine oil, engine oil filters and fuel filter elements more frequently then with diesel fuel. Biodiesel can remove rust and other particles that adhere to the inside of the fuel tank. These particles are then trapped by the vehicle filters and may cause shortened filter life and/or filter blockages. In cold weather, this is more likely to occur. Consult your dealer for information on cold weather operation and proper maintenance inter vals when using any biodiesel fuel blend.

5-6

When handling biodiesel fuel, care must be taken not to allow water into the fuel supply. Biodiesel fuel will actually attract moisture from the atmosphere. Fuel tanks must be kept as full as possible to limit the amount of air and water vapors in them. It may be necessary to drain the fuel filter water tap more frequently.

Potential oxidation and stability could be a problem with the fuel store in the machine.

Biodiesel fuel may degrade natural rubber gaskets and hoses, as it is more solvent than petro-diesel.

Check hoses and other engine components more frequently when using a biodiesel fuel.

DO NOT allow water to collect in the fuel or storage tanks. Keep fuel tanks and storage tanks as full as possible to limit the amount of air and water vapors. It may be necessary to drain the machine fuel filter more frequently. Potential oxidation and stability could create a problem with fuel stored in the machine.

BIODIESEL STORAGE NOTICE: DO NOT store machines for more than three months with biodiesel blends in the fuel system. DO NOT store biodiesel fuel in on-site storage tanks for more than three months.

If long periods of storage are required, run the machine for 20 hours using regular diesel fuel in order to flush the biodiesel fuel from the engine fuel system.

NOTICE: Biodiesel fuel must not be stored in on-site storage tanks for more than 3 months.

Any spillage of biodiesel fuel must be cleaned up immediately before it can cause damage to the environment and/or the paint finish of the machine.

Before using biodiesel fuel blends, you should consult with your dealer to receive full information about the approved blend for your machine and any detailed conditions of its usage.

Be aware that not fulfilling the requirements and conditions of biodiesel fuel usage will void your machine’s warranty.

CHAPTER 5 - LUBRICATION, FILTERS, AND FLUIDS

USE OF BIO-DEGRADABLE OILS When you use Bio-degradable Oil (BIO OIL), refer to the following information: 1. There are two types of BIO OIL available; vegetable based and synthetic based. Synthetic based type is recommended, as the vegetable based oil has a maximum usage temperature of 80°C (176°F). The degradation of vegetable based oil occurs more rapidly and causes reduced service life.

2. Do not mix either type of BIO OIL with the original factory filled mineral oil. If BIO OIL is used, it is required to flush the hydraulic system that was filled with mineral oil twice, before adding bio oil.

3. If you use BIO OIL, swing and propel parking brake performance will be reduced, because of the lower friction of BIO OIL compared to that mineral oil.

4. For further information about recommended Bio-degradable oil, please contact local dealer.

CHAPTER 6 - MAINTENANCE AND ADJUSTMENTS GUIDELINES TO REPLACE GROUND TOOLS

GUIDELINES FOR ATTACHMENT LUBRICATION

It is very important to keep bucket teeth and side cutters properly tightened. Loose or missing bolts will increase loads and eventually cause tool failure.

Extended operation with loose hardware can cause the bolts to stretch and wear on the support mounting holes. Heating of hardware and support mounting holes will cause the same effect. Follow these general guidelines to insure proper tightness of hardware on bucket teeth and side cutters.

Lubricate attachment pins according to the intervals indicated in the Maintenance Chart. Use extreme pressure multipur pose grease No. 2 EP type.

Lubr icate all points until grease purges. The lubrication intervals are based on an average duty cycle. Average duty cycle is defined as Most typical digging application, road construction in natural bed clay, digging 50% - 60% of the daily work schedule

• When installing new cutting edges, end bits, side cutters, and bucket teeth, make sure that all supporting surfaces are free of dirt, paint, debris, rust, scale or weld splatter. All mating surfaces must be clean and flat to insure that maximum clamping force is obtained.

• Make sure that all bolts and nut threads are clean and dry. DO NOT APPLY ANY TYPE OF LUBRICANT.

• When installing end bits, start at the center and work toward the outside edges.

• Always torque bolts according to specifications.

• For best results, strike all head bolts with a heavy hammer to seat them properly before final torque.

WARNING Avoid eye injury when using a drill, hammer, saw, or other tools that may cause chips to fly. Always wear safety glasses when working. Failure to comply could result in death or serious injury.

M428B

• When new parts are used, the mating surfaces will seat more uniformly and the bolts torque will be less than the standard value after a short period of operation. Make sure to check all bolts for proper tightness on new parts after eight (8) hours of operation.

• Lower maintenance costs by replacing, turning, or rotating cutting edges before they reach their wear limits.

• When finding loose bolts, check bolts for elongation and support mount holes for wear.

Replace bolts and repair any wear on support mounting hole if needed. Torque bolts according to specifications.

6-8

New pins and bushings, including new machines and repairs require special break-in procedures. While both pin and bushing have a special ground finish, they still have to be mated to each other to eliminate the machining high points.

Because of these high spots, it is recommended that the front attachment or the repaired area be lubricated a minimum of once every eight (8) hours for the first 50 hours for a standard machine working in an average duty cycle. This lubrication procedure will reduce the possibility of a premature pin or bushing failure during the break-in period.

While grease grooves in the bushings allow grease to move around the bushing, it does not insure that grease gets on all of the bushing surfaces. Any load on the joint will prevent the grease from getting to the wear surfaces in the loaded area. Due to the fact that a hand operated grease dispenser does not provide the volume of grease that a power system does, there is a greater possibility of bushing galling, unless the standard lubr ication procedure is modified. No matter how much grease is pumped into the pin bushing cavity with a hand grease gun, the grease will tend to escape to the outside before filling the grease cavity. Therefore, to avoid this situation, the front attachment has to be repositioned during the lubrication process, to move the load area and allow the grease to cover the entire grease cavity between the pin and bushing.

CHAPTER 8 - SPECIFICATIONS

LIFTING CAPACITIES 1. Do not attempt to lift any load that exceeds the rated values at their specified load radius and height.

2. Lifting capacities assume a machine standing on a level, firm, and uniform supporting surface.

Operator must make allowance for job conditions such as soft or uneven ground, out of level conditions, side loads, sudden stopping of loads, hazardous conditions, inexperienced personnel, weight of various other buckets, lifting slings, attachment, etc.

3. Rating at bucket lift hook.

4. The rated loads are in compliance with SAE Hydraulic Excavator Lift Capacity Standard J1097. They do not exceed 87% of hydraulic lifting capacity or 75% of tipping load. Rated loads marked with asterisk (*) are limited by hydraulic capacity rather than tipping load.

8-10

5. Capacities apply to the machine as originally manufactured and normally equipped by the manufacturer.

NOTICE: The operator must consider the weight of any device utilized for lifting to properly calculate the total lifting capacity of the machine. Example: 1. If the excavator uses the same bucket size indicated in the Lifting Chart, and a lifting cable, etc. weighing 100 kg (220 lbs) is used for lifting, then you have to subtract this additional 100 kg (220 lbs) from every value indicated in the Lifting Chart accordingly.

2. If a bucket is changed for a larger bucket, which weight is more than the bucket indicated in the Lifting Chart, then you have to subtract this additional weight from every value indicated in the Lifting Chart accordingly.

3. If a bucket is changed for a smaller bucket, which weight is less than the bucket indicated in the Lifting Chart, then you can add this additional weight to every value indicated in the Lifting Chart accordingly.
