- Page 4 Foreword hydraulic breaker Basic safety precautions are outlined in the "Safety" section of this manual and in the description of operations where hazards exist. Warning labels have also been put on the machine to provide instructions and to identify specific hazards which if not observed could cause bodily injury or death to you or other persons.
- Page 5 hydraulic breaker Warranty A complete warranty claim for a hydraulic breaker attachment includes at least the following information. Model and serial number Carrier model Working hours and service history Application Providing this information makes it easy to handle the warranty claim prop- erly and swiftly.
- Page 6 Machine numbers hydraulic breaker The equipment serial number is stamped on the valve body. The model and serial number are also located on the CE marking. Check that the model cor- responds to the one given on the cover of this manual. It is important to make correct reference to the serial number of the attach- ment when making repairs or ordering spare parts.
- Page 7 Product introduction The product is a hydraulically operated breaker. It can be used on all AVANT-carriers which meet the necessary hydraulic and mechanical installation re- quirements. The unit functions by repeatedly raising a steel piston and driving it down onto the head of a removable breaking tool.
- Page 8 Product introduction hydraulic breaker Lifting devices must safely carry the working weight of the product. See “Hammer specifications” on page 46. Place chains or slings, as shown by the illustration, to lift the product. Below are some common safety instructions concerning lifting operations. In addition to this, the local, national standards for machines and lifting-tack- les must always be strictly observed.

- Page 10 Safety hydraulic breaker All mechanical equipment can be hazardous if operated without due care or correct maintenance. Most accidents involving machine operation and maintenance are caused by failure to observe basic safety rules or precau- tions. An accident can often be avoided by recognizing potentially hazard- ous situations before an accident occurs.
- Page 11 hydraulic breaker Safety Study also the operating and maintenance manual of your carrier before op- erating the attachment. All the time you are working with the product, take care and stay alert. Al- ways be alert for hazards. The possibility of a serious or even fatal accident is increased when you are intoxicated.
- Page 12 Safety hydraulic breaker Work sites can be hazardous. Inspect the site before working on it. Check for potholes, weak ground, hidden rocks etc. Check for utilities (elec- tric cables, gas and water pipes etc.). Mark the positions of underground ca- bles and pipes if you will be breaking the ground.
- Page 13 hydraulic breaker Safety Wear ear protection against high noise level to prevent personal injury. Operating the product beyond its design limits can cause damage. It can also be dangerous. See “Hammer specifications” on page 46. Do not try to enhance the product's performance by unapproved modifica- tions.
- Page 14 Safety hydraulic breaker Hydraulic fluid at system pressure can injure you. Before disconnecting or connecting hydraulic hoses, stop the carrier engine, operate the controls to release pressure trapped in the hoses. During the operation, keep people away from the hydraulic hoses. There might be pressurized oil trapped inside the product even if it is discon- nected from the carrier.
- Page 15 hydraulic breaker Safety Defective equipment can injure you or others. Do not operate equipment which is defective or has missing parts. Make sure the maintenance procedures in this manual are completed be- fore using the product. Do not try to do repairs or any other maintenance work you do not under- stand.
- Page 16 Operation hydraulic breaker The hammer is designed to be used in breaking concrete, road surface or asphalt, hard or frozen ground. It is also suitable for light trenching and benching applications or in ground compacting. It can be also used in break- ing small and soft boulders.
- Page 17 hydraulic breaker Operation To increase the hammer's working life, pay particular attention to correct working methods and how to choose the correct tool for the job. There are essentially two ways of breaking with a hydraulic hammer. Penetrative breaking (or cutting) In this form of breaking a moil point or chisel tool is forced inside the mate- rial.
- Page 18 Operation hydraulic breaker 1. Set the engine speed to the recommended engine RPM for correct amount of oil supply. 2. Carefully operate the carrier controls to place the hammer and boom into the breaking position. Quick and careless boom movements could result in damage to the hammer.
- Page 19 hydraulic breaker Operation 7. A safety screen is recommended to protect the operator from flying debris. Keep the cabin windows and doors closed during operation. 8. Note: Listen to the hammer's sound when you are using it. If the sound becomes weaker and the impact less efficient, the tool is misaligned with the material and/or there is not enough down force on the tool.
- Page 20 Operation hydraulic breaker 13. Stop the hammer quickly. Do not allow the hammer to fall down and make idle strokes when an object breaks. Frequent idle strokes have a deteriorating effect on the hammer. If the hammer falls through, the housing wears out more quickly.
- Page 21 hydraulic breaker Operation 20. Do not use the hammer or hammer tools for lifting. (see picture 8) 21. The tool shank must be well greased during operation. Regular visual in- spections during operation are recommended. An unlubricated tool shank requires more frequent greasing intervals. A tool shank covered with excessive grease requires less frequent greasing intervals.
- Page 22 Operation hydraulic breaker Stage 1: • Lift up the two locking pins on both sides of the attachment coupling plate and turn them backward so that they remain in the up position • Make sure that the pins remain in the up position, otherwise you cannot couple the attachment properly! Stage 2: •...
- Page 23 hydraulic breaker Operation The transportation and parking positions are shown below. When moving with the hammer, ensure that the hammer is not too close to the ground. Also make sure that you see the tip of the tool at all times. 1.
- Page 24 Operation hydraulic breaker In case of special conditions of use, please consult your local dealer for in- structions. Observe the following points when the hammer is stored. In this way the vital parts of the attachment are protected from rust and the machine is ready to be used whenever necessary.

Position the hammer standing upright resting on the tool on firm surface. 2. Stop carrier engine and wait 10 minutes for oil pressure to drop inside hammer.
- Page 28 The machine must be moved to bring the oil tem- perature above 0 °C before hammering can start (viscosity 1000 cSt or 131 °E). AVANT Recommends: Shell tellus TX46 in normal conditions. Shell tellus TX68 when ambient temperature exceeds 35 °C.
- Page 29 hydraulic breaker Carrier hydraulic oil Table below shows hydraulic oils recommended for hammer use. The most suitable oil is selected in such a way that the temperature of the hydraulic oil in continuous use is in the ideal area on the chart and the hydraulic system is used to best advantage.
- Page 30 35 °C. The correct hydraulic oil viscosity is thus ensured. Make sure that the AVANT carrier is equipped with an oil cooler before installing the hammer.
