Page 8: Product Introduction
Product introduction S 83 STD 3. PRODUCT INTRODUCTION 3.1 OVERVIEW The product is a hydraulically operated breaker. It can be used on any carrier which meets the necessary hydraulic and mechanical installation requirements. The unit functions by repeatedly raising a steel piston and driving it down onto the head of a removable breaking tool.

Page 12: Safety
Safety S 83 STD 4. SAFETY 4.1 GENERAL SAFETY 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 precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident oc- curs.
Page 13 S 83 STD Safety CLOTHING You can be injured if you do not wear proper clothing. Loose clothing can get caught in the machinery. Wear protective clothing to suit the job. Examples are: a safety helmet, safety shoes, safety glasses, well-fitting overalls, ear-protectors and industrial gloves.
Page 14 Safety S 83 STD FLYING CHIPS OF ROCK R010213 Protect yourself and your neighbourhood against flying chips of rock. Do not oper- ate the product or carrier if someone is too close. Keep the cabin windows and doors closed during operation. Window bars are rec- ommended to protect the windows from flying chips of rock.
Page 15 S 83 STD Safety HYDRAULIC HOSES AND FITTINGS Ensure all hydraulic components will withstand maximum pressure and mechanical stresses caused by operation of the attachment. Consult your local dealer for instruc- tions. FIRE HAZARD Most hydraulic fluids are flammable and might ignite when contacting hot surface.
Page 16 Safety S 83 STD LIFTING EQUIPMENT You can be injured if you use faulty lifting equipment. Make sure that lifting equip- ment is in good condition. Make sure that the lifting tackle complies with all local regulations and is suitable for the job. Make sure that the lifting equipment is strong enough for the job and you know how to use it.
Page 17: Operation
S 83 STD Operation 5. OPERATION 5.1 OPERATING INSTRUCTIONS RECOMMENDED USE The hammer is designed to be used in breaking oversized boulders, demolishing heavily reinforced concrete structures and for major heavy excavation and clearing work. It can be also used for primary breaking, tunnelling and removal of metallur- gical slag.
Page 18 Operation S 83 STD Noise dampening Operating the hammer near residential areas or other noise sensitive areas can cause noise pollution. In order to avoid unnecessary noise, please follow these basic rules: 1. When operating with the hammer, keep the tool at 90 degree angle to the mate- rial and the feed force in-line with the tool.
Page 19 S 83 STD Operation Chisel, moil point and pyramid ■ For sedimentary (e.g. sandstone) and weak metamorphic rock into which the tool penetrates. ■ Concrete. ■ Trenching and benching. Blunt tool ■ For igneous (e.g. granite) and tough metamorphic rock (e.g. gneiss) into which the tool doesn't penetrate.
Page 20: Daily Operation
Operation S 83 STD 5.2 DAILY OPERATION Warning! Protect yourself and your neighbourhood against flying chips of rock. Do not operate the hammer or carrier if someone is too close to the ham- mer. The hammer as a standard assembly, must not be used under water. If water fills the space where the piston strikes the tool, a strong pressure wave is gen- erated and the hammer may be damaged.
Page 21 S 83 STD Operation 4. Use the excavator boom to press the hammer firmly against the object. Do not pry the hammer with the boom. Do not press too hard or too gently with the boom. The correct force is applied, when the tracks start to lift slightly from the ground.
Page 22 Operation S 83 STD 6. When demolishing vertical structures (e.g. brick walls), place the tool against the wall at a 90 degree angle. 7. Start the hammer. 8. A safety screen is recommended to protect the operator from flying debris.
Page 23 S 83 STD Operation 10. 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 hammer and change the po- sition of the tool. Working too long in one spot will create stone dust under the tool.
Page 24 Operation S 83 STD 14. 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 quick- 15.
Page 25 S 83 STD Operation 17. Do not use the hammer tools to move rocks. The stone claws are designed for this purposes. 18. Do not use the hammer to sweep the ground of debris. This may damage the hammer and the housing will wear out more quickly.
Page 26 Operation S 83 STD 20. Do not operate the hammer with the carrier's boom, stick or bucket cylinders at the end of their stroke (either fully extended or fully retracted). Damage to the carrier may result. 21. Do not use the hammer or hammer tools for lifting. Lifting eyes on the hammer are for storage and maintenance purposes only.

Operation S 83 STD 5.4 MOVEMENT The transportation and parking positions are shown below. When moving with the hammer, ensure that it isn't too close and doesn't point at the cabin window. 5.5 SPECIAL CONDITIONS OF USE If hammer is to be used in conditions that differ from normal breaking or demolition work conditions, such as: ■...
Page 29: Storage
S 83 STD Operation 5.6 STORAGE LONG TERM STORAGE 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 when- ever necessary.

Page 33 S 83 STD Hammer tool greasing CORRECT GREASING 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. 3. Apply tool grease from grease gun to greasing points marked with the following sticker.
Page 34: Carrier Hydraulic Oil
Carrier hydraulic oil S 83 STD 2. CARRIER HYDRAULIC OIL 2.1 REQUIREMENTS FOR HYDRAULIC OIL GENERAL REQUIREMENTS In general the hydraulic oil originally intended for the carrier can be used with this product. However, since working with the product heats the oil more than the usual excavation work, the temperature of the oil must be monitored.
Page 35 S 83 STD Carrier hydraulic oil OIL SPECIFICATIONS 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 advan- tage.
Page 36: Oil Cooler
Carrier hydraulic oil S 83 STD Oil too thin ■ Efficiency losses (internal leaks) ■ Damage to gaskets and seals, leaks ■ Accelerated wearing of parts, because of decreased lubrication efficiency ■ Hammer strikes irregularly and slowly ■ Danger of cavitation in pumps and in the hydraulic hammer Note: We strongly recommend the use of different hydraulic oils in the summer and in the winter if there is an average temperature difference of more than 35 °C (95...

Page 38 Carrier hydraulic oil S 83 STD The damage caused by hydraulic oil impurities in the carrier and hammer circuits: The working life of the pumps and other components is significantly shortened. ■ Rapid wear of parts. ■ Cavitation. 2. Wear of cylinder and gaskets.
Page 40: Routine Maintenance
Routine maintenance S 83 STD 1. ROUTINE MAINTENANCE 1.1 OVERVIEW This product is a precision made hydraulic machine. Therefore great care and clean- liness should be taken when handling any of the hydraulic components. Dirt is the worst enemy in hydraulic systems.
Page 41: Dealer
S 83 STD Routine maintenance EVERY 50 HOURS OR AT LEAST ONCE A MONTH ■ Check the tool shank and tool bushings for wear. See “Removal of tool” on page 43. See “Lower tool bushing” on page 46. ■ Check the hydraulic hoses. Replace if necessary. Do not let dirt get into the hammer or hoses.
Page 42: Maintenance Intervals In Special
Routine maintenance S 83 STD 1.4 MAINTENANCE INTERVALS IN SPECIAL APPLICATIONS The service interval is considerably shorter in special applications. See “Special conditions of use” on page 28. In special applications, please consult your local dealer for the correct service intervals.
