0 - 1 SAFETY PRECAUTIONS Safety Symbols Most accidents come from neglect of basic safety precautions or rules or pre-operation inspection or maintenance. Those could be avoided if possible hazards are well understood and measures are taken. Before operation, be sure to read and understand operating instructions as well as safety precautions in this manual. Safety symbols in this manual are classified as follows: DANGER Indicates an extremely hazardous situation which, if not observed and handled properly, will result in death or serious injury (risk of death or serious injury). WARNING Indicates a potentially hazardous situation which, if not observed and handled properly, could result in death or serious injury (possibility of death or serious injury). CAUTION Indicates a potentially hazardous situation which, if not observed and handled properly, may result in minor or moderate injury. NOTICE Indicates precautions related to personal safety or property. Note DANGER or WARNING should not be considered for property damage accidents unless personal injury risk appropriate to these levels is also involved. CAUTION (and NOTICE) is permitted for property -damage- only accidents. Every message with safety symbols includes preventive measures to avoid danger. We, Furukawa however, could not anticipate every possible hazard completely so safety precautions are included in this manual as many as possible. Ensure your safety, strictly observing those safety precautions.

0 - 2 OUTLINE OF MACHINE Use Of The Breaker Applications This breaker is used to break or smash hard rocks, concrete slabs etc and to dig hard, sold ground in a mine, quarry or construction site (road, railroad, dam, demolition, preparation etc). • Breaking by striking • Demolishing by striking • Digging by striking WARNING Do not use this breaker for any applications other than specified above. Warming-up operation This breaker is already factory-adjusted and checked before shipment. To maintain breaker's performance and lengthen service life of breaker, operate breaker properly, considering the following: • Perform warming-up operation for five minutes after starting engine. • After warming-up, move boom, arm etc for about five minutes to raise the hydraulic oil temperature. • When breaking or doing demolishing work, move the hand throttle to 'Mid' position and operate breaker properly without putting overstress.
