Never use the hydraulic breaker to sweep the ground to spread rubble, to push objects or carry out lifting operations.

6.

Do not operate the hydraulic breaker with the attachment cylinders up to the end of their stroke (extended or retracted).

7.

Do not operate the hydraulic breaker if the tool is in contact with some part of the machine.

8.

Place the tool against the object at a 90 degree angle. Avoid small irregularities on the object which will break easily and cause either idle strokes or an incorrect working angle.

3-6

9.

When demolishing vertical structures (e.g brick walls), place the tool against the wall at a 90 degree angle.

10. Use a safety screen to protect yourself from flying debris. Keep the cab windows closed during operation.

11. Listen to the noise the hydraulic breaker makes while you are using it. If the pitch of the noise rises and, at the same time, the force of impact diminishes, this means that the tool is not properly aligned with the material and/or that there is not enough downward force on the tool. Realign the tool and press it firmly against the material.

12. Do not strike in one spot for more than 15 seconds at a time. If the object does not break, or if the tool does not penetrate, stop the breaker and change the position of the tool.

13. For the hydraulic breaker to be most effective when breaking boulders work progressively in small steps from the outer edge towards the middle.

14. When breaking hard or frozen ground, use the benching method. Start by clearing a small area working from the edge. Then continue by breaking material towards the open area.

15. Do not operate the hydraulic breaker in the air, with nothing to hit. Frequent idle strokes have a deteriorating effect on the hydraulic breaker.

16. When breaking concrete, hard or frozen ground, never strike and pry with the tool at the same time.

The tool may snap off. Bending may be caused by stones inside hard or frozen ground. Be careful and stop striking if you encounter sudden resistance under the tool.

17. Keep the tool at a 90 degree angle at all times. If the object moves or if its surface breaks, correct the angle immediately. Keep the hydraulic force and tool aligned.

18. The tool shank should be kept well greased during operation. Regular visual checks should be made during operation.

CS99C626

37

5-21

SECTION 5 - OPERATING INSTRUCTIONS HYDRAULIC BREAKER OPERATION To increase the hydraulic breaker’s working life, pay particular attention to correct working methods and to the correct choice of tool for the job. There are essentially two ways of breaking with a hydraulic breaker.

BREAKING BY PENETRATION (or cutting) In this form of breaking a moil point or chisel tool is forced inside the material. This method is most effective in soft, layered or plastic, low abrasive material.

The high impact rate of the small breakers makes them ideal for penetrative breaking.

BREAKING BY IMPACT With impact breaking, the material is broken by transferring very strong mechanical stress waves from the tool into the material. The best possible energy transfer between the tool and the object is achieved with a blunt tool.

Impact breaking is most effective in hard, brittle and very abrasive materials. The use of a chisel tool in hard material will cause the sharp edge to wear very quickly. The high impact energy of the big breakers makes them ideal for impact breaking.

CHOICE OF HYDRAULIC BREAKER TOOLS A selection of standard and special tools to suit each application are available. The correct type of tool must be selected to get the best possible working results and longest life time for the tool. Choosing the best tool type for an application may require some testing. See your CASE Dealer.

CHISEL AND MOIL -

-

For sedimentary (e.g. sandstone) and weak metamorphic rock into which the tool penetrates.

Concrete.

Trenching and benching.

SPADE TOOL -

Frozen or compact ground Asphalt.

COMPACTING PLATE -

Ground compacting.

It is important to choose a tool which is suitable for your breaker and for the intended application. The choice of tool depends on the hydraulic breaker model. See "Tools" in the "Specifications" Section.

SPECIAL CONDITIONS OF HYDRAULIC BREAKER USE If the breaker is to be used in conditions that differ from normal breaking or demolition work conditions, such as: -

-

Tunnelling; Foundry cleaning; Underwater operations; Operations in extremely low or high temperatures; Use of special hydraulic fluids; Breaker operations with special attachment (extra long boom etc.)

Other special conditions,

that may require modifications to attachment, special operating techniques, increased maintenance or special wear items.

In case of special conditions of use, please consult your CASE Dealer.

When performing maintenance on the machine, place a "Do not start up" label on the instrument panel. Never leave the operator’s compartment when the engine is running.

Any modification to this machine without prior authorization could cause serious injury. Do not make any modifications without authorization. Consult your CASE Dealer.

IMPORTANT: If you use your machine in particularly harsh conditions (dusty or corrosive atmosphere, etc.), the servicing intervals should be reduced accordingly.

IMPORTANT: Take particular care to replace all filters regularly. Clean filters mean longer engine running life.

IMPORTANT: Oil and fluid should not be thrown on the ground. They must be stored and removed by a company which is responsible for their recycling or their disposal.

!

The attachment is raised or if the machine moves without an operator, serious injury can result.

Before performing any maintenance, the following steps must be carried out: 1. Park the machine on flat, horizontal ground.

2. Lower the attachment until it is resting on the ground.

3. Lower the dozer blade until it is resting on the ground.

4. Stop the engine and remove the starter switch key.

5. Lock the tracks to prevent any machine movement.

SECTION 7 - SERVICING INTERVALS HYDRAULIC BREAKER SERVICING INSTRUCTIONS Every 2 hours

Every 600 hours or once a year

Grease the tool shank and the tool bushing.

Have the hydraulic hammer thoroughly checked by your CASE Dealer.

Tighten any loose connections (where necessary).

Check the impact efficiency and evenness of operation.

Every 10 hours or at least once a week Remove the tool retaining pins and check their condition. Grind burrs away if necessary. See "Replacing a tool" in the "Maintenance/Adjustments" Section.

Check that the tool has received sufficient greasing.

Grease more frequently, if necessary.

Every 50 hours or a least once a month IMPORTANT: It is preferable to have the first servicing after 50 hours operation carried out by your CASE Dealer.

Check the tool shank and tool bushing for wear. See "Replacing a tool" in the "Maintenance/Adjustments" Section.

Check the hydraulic hoses. Replace them if necessary.

Make sure the hydraulic hammer moves freely in its housing and that the anti-vibration components (buffers and pads) are in good condition.

Check the condition of the wear plates by moving the hydraulic breaker from one side of the housing the other with a prybar. The maximum acceptable play is approximately 10 mm.

7-2

MAINTENANCE INTERVALS Service intervals are considerably shorter for such applications as breaker tunnelling, sealing, foundry cleaning, underwater use, etc. For special applications, consult your CASE Dealer.

SECTION 7 - SERVICING INTERVALS HOURMETER The hourmeter enables servicing operations to be scheduled. It works in the same way as a clock when the engine is running.

Servicing intervals are carefully calculated to guarantee safe and efficient machine operation.

Be sure to carry out all the servicing operations properly as defined in this manual.

LUBRICATION/FILTERS/FLUIDS FLUIDS AND LUBRICANTS Fluids and lubricants must have the correct properties for each application.

!

WARNING

!

The conditions of use for individual fluids and lubricants must be respected.

ENGINE OIL CASE N°1 motor oil is the oil recommended for your engine. This oil ensures correct lubrication of your engine in all working conditions.

If CASE N°1 Multiperformance or Performance engine oil cannot be obtained, use only oil of the API/CG/CF category.

HYDRAULIC FLUID CASE hydraulic fluid is specially designed for high pressure applications and for the CASE hydraulic system. The type of fluid to be used depends on the ambient temperature.

NOTE: Do not put any Performance Additive or other additive in the sump. Oil change intervals shown in this manual are based on tests carried out on CASE lubricants.

Temperate climates -5°C to +40°C Fluid type ISO VG 46 Hot climates 0°C to +60°C Fluid type ISO VG 100 Cold climates -40°C to +20°C Fluid type ISO VG 22 These various grades of fluid must be in conformity with CASE. TRANSMISSION COMPONENT OIL Extreme Pressure oil is used for all cased transmission components.

Extreme Pressure oil Type API GL5 grade 85W140 or ISO VG 220.

GREASE The type of grease to be used depends on the ambient temperature.

Temperate and hot climates -20°C to +60°C Extreme pressure grease EP NLGI Grade 2 with molybdenum disulphide.

Cold climates -40°C to +20°C Extreme pressure grease EP NLGI Grade 0.

(A) Fahrenheit temperature (B) Celsius temperature (1) All seasons (2) Winter (3) Tropical (4) Arctic (*) Use of an engine oil heater, or and engine coolant heater is required.

FUEL Use fuel which is to ASTM (American Society for Testing of Materials) D975 Standard.

Use No. 2 grade fuel. The use of other types of fuel can result in a loss of power and can cause high fuel consumption.

When the temperature is very cold, the use of a mixture of number one and number two fuels is permitted.

See your fuel vendor for Winter fuel requirements in your area.

If the temperature falls below the fuel cloud point (point at which wax begins to form) the wax crystals will cause power loss or prevent the engine from starting.

IMPORTANT: In cold weather, fill the fuel tank at the end of the day’s work, in order to prevent the formation of condensation.

8-2

Fuel storage Long storage can lead to the accumulation of impurities and condensation in the fuel. Engine trouble can often be traced to the presence of water in the fuel.

The storage tank must be placed outside and the temperature of the fuel should be kept as low as possible.

Drain off water and impurities regularly.

COOLANT SOLUTION Put only ethylene-glycol coolant solution in the cooling system. Use good quality ethylene-glycol that has a high boiling point, with no additives to prevent leakage.

Do not use non-approved anti-rust additives. Anti-rust additives and ethylene-glycol can mix and work against each other, thereby reducing anti-corrosion protection, forming deposits in the cooling system and causing damage to the cooling system and radiator.

Consult your CASE Dealer for suitable coolant solution.

SECTION 8 - LUBRICATION/FILTERS/FLUIDS ANTI-FREEZE/ANTI-CORROSION

PLASTIC AND RESIN PARTS

Use anti-freeze in all seasons to protect the cooling system from corrosion and all risk of freezing.

When cleaning plastic windows, the console, the instrument panel, the indicators, etc., avoid the use of petrol, paraffin, paint solvents, etc. Use only water, soap and a soft cloth.

For areas where ambient temperature is above -36°C, use a blend of 50% ethylene-glycol based anti-freeze.

For areas where the ambient temperature is below – 36°C, it is advisable to use a blend of 40% water and 60% anti-freeze.

The use of petrol, paraffin, paint solvents, etc. will cause discoloration, cracks or deformation of these parts.

ENVIRONMENT Always think of the environment before carrying out maintenance operation on this machine and before disposing of used fluids or lubricants. Never throw oil or fluid on the ground and never place them in leaking receptacles.

Consult your local ethnological recycling centre or your CASE Dealer to obtain information on the correct method of disposing of these materials.

SECTION 8 - LUBRICATION/FILTERS/FLUIDS HYDRAULIC BREAKER LUBRICATION GREASING INTERVALS 1.

The tool shank must be well lubricated before installing.

2.

Press the grease gun between 5 to 10 times, at regular intervals, to grease the tool bushing and the tool.

3.

Adapt the intervals and the quantity of grease to the wear rate of the tool and to working conditions.

This can be anything between every two hours and once a day, depending on the type of material (rock/concrete) being broken.

Insufficient greasing or improper grease may cause: - Abnormal wear of tool bushing and tool, - Tool breakage CORRECT GREASING While greasing, the hydraulic breaker must be standing upright resting on the tool to ensure that the grease will penetrate downwards between the tool and the bushing.

Do not fill the space between the piston and the tool with grease. A lower piston seal failure can result and the hydraulic breaker will eventually leak oil.

GREASE POINTS Use the following grease: EP NLGI grade 2 (for temperate and hot climates) 20°C to +60°C EP NLGI grade 0 (for cold climates) -40°C to +20° Tool shank ................................................................
