  • 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 Installation: Oil flow, operating pressure and return line pressure if known 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 48. 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 The related safety label on the hammer and the text on the label are shown here. 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 Stop working, when bystanders are in the area of airborne pollutants and make sure they have proper respirators. Respirators are as important for bystanders as hard hats.Respirators for both operator and bystanders must be approved by the respirator manufacturer for the application in question. It is essential that the respirators protect from the tiny dust particles which cause silicosis and which may cause other serious lung diseases.
  • Page 14 Safety hydraulic breaker Operating the product beyond its design limits can cause damage. It can also be dangerous. See “Hammer specifications” on page 48. Do not try to enhance the product's performance by unapproved modifica- tions. Fine jets of hydraulic fluid at high pressure can penetrate the skin. Do not use your fingers to check for hydraulic fluid leaks.
  • Page 15 hydraulic breaker Safety The safety label on or near the accumulator is shown here: The hammer incorporates one or two pressure accumulators, depending on the model. The accumulators are pressurized even when there is no hydraulic pressure to the hammer. Attempting to dismantle the accumulators without first releasing the pressure can cause injury or death.

  • Page 18 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 19 hydraulic breaker Operation Impact breaking With impact breaking, the material is broken by transferring very strong mechanical stress waves from the tool into the material. Impact breaking is most effective in hard, brittle and very abrasive materials. The high impact energy of the big hammers makes them ideal for impact breaking.
  • Page 20 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 21 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 22 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 23 hydraulic breaker Operation 17. Do not use the hammer or hammer tools for lifting. (see picture 8) 18. 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 24 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 25 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 26 Operation hydraulic breaker 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. 1. The storage area must be dry. 2.

  • Page 28 Hammer tool greasing hydraulic breaker For tool lubrication use a grease that meets the following criteria: • No dropping point or very high, over 250 °C (480 °F). • Maximum service temperature at least 150 °C (300 °F). • Minimum working temperature below lowest ambient temperature. •...
  • Page 29 hydraulic breaker Hammer tool greasing Insufficient greasing or improper grease may cause: l Abnormal wear of tool bushing and tool l Tool breakage 1. 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 30 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 31 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 32 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.

  • Page 34 Routine maintenance hydraulic breaker This product is a precision made hydraulic machine. Therefore great care and cleanliness should be taken when handling any of the hydraulic compo- nents. Dirt is the worst enemy in hydraulic systems. Handle the parts carefully and remember to cover any cleaned and dried parts with clean lint-free cloth.
  • Page 35 hydraulic breaker Routine maintenance Note: The time intervals given refer to the carrier hours while the attachment is installed. t is recommended to have the first inspection done by your local dealer after 50 to 100 operating hours. Contact your local dealer for more information about the initial 50-hour inspection.
