Machine and Tool operating Hazards Sudden or unexpected movement of the machine may occur during operating, which may cause injuries. Furthermore, losing your bal ance or slipping may cause injury. To reduce risks:

• Make sure that you always keep a stable position with your feet as far apart as the width of your shoulders, and keeping your body weight balanced out.

• 6WDQG¿UPO\DQGDOZD\VKROGRQWRWKHPDFKLQHZLWKERWKKDQGV

• Do not start the machine when it is lying on the ground.

• Make sure that the handles are clean and free from grease and oil. Unintentional start of the machine may cause injury!

• Keep your hands away from the start and stop device until you are ready to start work. The working tool is exposed to heavy strains when the machine is used and after a certain amount of use the tool may break due to fatigue. If the tool breaks, there may be sudden or strong movements. Such sudden or strong movements may cause serious injury.

• Make sure that you always keep a stable position with your feet as far apart as the width of your shoulders, and keeping your body weight balanced.

• Keep your hands and feet away from the working tool.

• Do not ‘ride’ on the machine with one leg over the handle, since you could be seriously injured if the tool were to break suddenly.

• Check regularly for wear to the working tool, and check whether there are any signs of damage or visible cracks. An incorrect dimension of the working tool’s shank can result in the working tool being lost or slipping out during operation. A working tool that is lost or slips out can cause personal injury.

• Before inserting the work tool, make sure that the shank’s dimensions are correct for use in the machine.

• Working tools without a collar may not be used. If the tool retainer on the machine is not in a locked position, the tool can be ejected with force, which can cause personal injury.

• Once the working tool has been mounted and locked, the locking function must be checked by pulling the working tool outwards forcefully.

• Make sure that the tool is fully inserted and the tool retainer is in the locked position before the machine is started.

• Never point the working tool at yourself or anyone else. Starting the machine while changing the working tool may cause personal injury.

• Take care of all spilled oil and handle it according to your local safety and environmental regulations. Hot hydraulic oil can cause burns.

• Never dismount the machine when the hydraulic oil is hot. Hydraulic oil can cause eczema when it comes in contact with the skin.

• Avoid getting hydraulic oil on your hands.

• Always use protective gloves when working with hydraulic oil. Grease can cause eczema when it comes in contact with the skin.

• Avoid getting grease on your hands. Explosion and Fire Hazard Breaking, drilling and working with certain materials can cause sparks, which may ignite explosive gases and cause explosions. Explosions may cause serious injury or death. To reduce such risk of explosion:

• Never operate the machine in any explosive environment.

• 'RQRWXVHWKHPDFKLQHQHDUÀDPPDEOHPDWHULDOVIXPHVRUGXVW

• Make sure that there are no undetected sources of gas. Electrical/Concealed Object Hazards The machine is not electrically insulated. If the machine comes into contact with electricity, serious injuries or death may result.

• To reduce the risk of such injury or death, never operate the machine near any electric wire or other source of electricity.

• Make sure that there are no concealed wires or other sources of electricity. During breaking, concealed wires and pipes constitute a danger that can result in serious injury.

• Before you start breaking, check the composition of the material you are to work on.

• Watch out for concealed cables and pipes e.g. electricity, telephone, water, gas and sewage lines etc.

• ,IWKHWRROVHHPVWRKDYHKLWDFRQFHDOHGREMHFWVZLWFKR௺WKHPDFKLQHLPPHGLDWHO\

• Make sure that there is no danger before continuing. Projectile Hazard During breaking, drilling or hammering, splinters or other particles from the worked material may become projectiles and cause personal injury by striking the operator or other persons.

• Use approved personal protective equipment, including impact resistant safety glasses with side protection, to reduce the risk of being injured by a projectile. Noise Hazard High sound levels may cause permanent hearing loss.

• Use hearing protection in accordance with occupational health and safety regulations.12 Silica/Dust Hazard ([SRVXUHWRFU\VWDOOLQHVLOLFDVRPHWLPHVFDOOHGµVLOLFDGXVW¶DVDUHVXOWRIEUHDNLQJGULOOLQJKDPPHULQJRURWKHUDFWLYLWLHVLQYROYLQJ URFNFRQFUHWHDVSKDOWRURWKHUPDWHULDOVPD\FDXVHVLOLFRVLVDVHULRXVOXQJGLVHDVHVLOLFRVLVUHODWHGLOOQHVVHVFDQFHURUGHDWK Silica is a major component of rock, sand and mineral ores. To reduce silica exposure:

• Use proper engineering controls to reduce the amount of silica in the air and the build-up of dust on equipment and surfaces. Examples of such controls include: Exhaust ventilation and dust collection systems, water sprays, and wet drilling. Make sure that controls are properly installed and maintained.

• Wear, maintain, and correctly use approved particulate respirators when engineering controls alone are not adequate to reduce exposure below permissible levels.

• 3DUWLFLSDWHLQDLUPRQLWRULQJPHGLFDOH[DPVDQGWUDLQLQJSURJUDPVR௺HUHGE\\RXUHPSOR\HUDQGZKHQUHTXLUHGE\ODZ

• Wear washable or disposable protective clothes at the worksite; shower and change into clean clothes before leaving the worksite to reduce exposure of silica to yourself, other persons, cars, homes, and other areas.

• Do not eat, drink, or use tobacco products in areas where there is dust containing crystalline silica.

• Wash your hands and face before eating, drinking, or using tobacco products outside of the exposure area.

• Work with your employer to reduce silica exposure at your worksite. Some dust, fumes or other airborne material created during use of the machine may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of such chemicals are:

• Crystalline silica and cement and other masonry products.

• Arsenic and chromium from chemically-treated rubber.

• Lead from lead based paints. To reduce your exposure to these chemicals, work in a well ventilated area, and work with approved safety equipment, such as dust

• Use only original parts and accessories approved by Altrad Belle. Vibration Hazard Normal and proper use of the machine exposes the operator to vibration. Regular and frequent exposure to vibration may cause,

FRQWULEXWHWRRUDJJUDYDWHLQMXU\RUGLVRUGHUVWRWKHRSHUDWRU¶V¿QJHUVKDQGVZULVWVDUPVVKRXOGHUVDQGRURWKHUERG\SDUWV

including debilitating and/or permanent injuries or disorders that may develop gradually over periods of weeks, months, or years. Such injury or disorder may include damage to the blood circulatory system, damage to the nervous system, damage to joints, and possibly damage to other body structures. If numbness, tingling, pain, clumsiness, weakened grip, whitening of the skin, or other symptoms occur at any time, when operating the machine or when not operating the machine, do not resume operating the machine and seek medical attention. Continued use of the machine after the occurrence of any such symptom may increase the risk of symptoms becoming more severe and/or permanent. The following may help to reduce exposure to vibration for the operator:

• Let the tool do the job. Use a minimum hand grip consistent with proper control and safe operation.

• When the impact mechanism is activated, the only body contact with the machine you should have is your hands on the handles. Avoid any other contact, e.g. supporting any part of the body against the machine or leaning onto the machine trying to increase the feed force. It is also important not to keep the trigger engaged while extracting the tool from the broken work surface.

• Make sure that the inserted tool is wellmaintained (including sharpness, if a cutting tool), not worn out, and of the proper size. Working tools that are not well-maintained, or that are worn out, or that are not of the proper size result in longer time to complete a task (and a longer period of exposure to vibration) and may result in or contribute to higher levels of vibration exposure.

• ,PPHGLDWHO\VWRSZRUNLQJLIWKHPDFKLQHVXGGHQO\VWDUWVWRYLEUDWHVWURQJO\%HIRUHUHVXPLQJWKHZRUN¿QGDQGUHPRYHWKHFDXVH of the increased vibrations.

• Comply with the recommended hydraulic pressure when operating the machine. Either higher or lower hydraulic pressure has the potential of resulting in higher levels of vibration.

• Machines and accessories must only be used for their intended purpose.

• Release the start and stop device immediately in all cases of power supply interruption.

• Always inspect the equipment prior to use. Do not use the equipment if you suspect that it is damaged.

• Always use your common sense and good judgment.

• Pay attention and look at what you are doing.

• 'RQRWXVHWKHPDFKLQHZKHQ\RXDUHWLUHGRUXQGHUWKHLQÀXHQFHRIGUXJVDOFRKRORUDQ\WKLQJHOVHWKDWPD\D௺HFW\RXUYLVLRQ reactions or judgment.

• Participate in safety and training courses.

• Never strike or abuse any equipment.

• Keep the machine and tools in a safe place, out of the reach of children and locked up.

• Make sure that all the attached and related equipment is properly maintained.

• Decals bearing important information regarding personal safety and care of the machine are supplied with every machine.

• New decals can be ordered from the Spare Parts list.

• Make sure that no unauthorized personnel trespass into the working zone.

• Keep the workplace clean and free from foreign objects.

• Never point a hydraulic hose at yourself or anyone else. PPE (Personal Protective Equipment) Always use approved protective equipment. Operators and all other persons in the working area must wear protective equipment, including at a minimum:

• Steel Toe capped footwear. Wear clothing suitable for the work you are doing. Tie back long hair and remove any jewellery which may catch in the equipment’s moving parts. Recommended Hydraulic Oil

In order to protect the environment, Altrad Belle recommends the use of biologically degradable hydraulic oil.

• Viscosity (preferred) 20-40 cSt.

• Viscosity (permitted) 15-100 cSt.

• Viscosity index Min. 100. Standard mineral or synthetic oil can be used. When the breaker is used continuously, the oil temperature will stabilise at a level which is called the working temperature. This will, depending on the type of work and the cooling capacity of the hydraulic system, be be WZHHQ&)DERYHWKHDPELHQWWHPSHUDWXUH At working temperature, the oil viscosity must lie within the preferred limits. The viscosity index indicates the connection between vis cosity and temperature. This is the reason why a high viscosity is preferred, because then the oil can be used within a wider tempera ture range. The breaker shall not be used, if oil viscosity fails to remain within the permitted area, or if the working temperature of the oil GRHVQRWIDOOEHWZHHQ·&·)DQG&) Storage

• Make sure that you always keep a stable position with your feet as far apart as the width of your shoulders, and keeping your body weight balanced out.

• 6WDQG¿UPO\DQGDOZD\VKROGRQWRWKHPDFKLQHZLWKERWKKDQGV

• Do not start the machine when it is lying on the ground.

• Make sure that the handles are clean and free from grease and oil. Unintentional start of the machine may cause injury!

• Keep your hands away from the start and stop device until you are ready to start work. The working tool is exposed to heavy strains when the machine is used and after a certain amount of use the tool may break due to fatigue. If the tool breaks, there may be sudden or strong movements. Such sudden or strong movements may cause serious injury.

• Make sure that you always keep a stable position with your feet as far apart as the width of your shoulders, and keeping your body weight balanced.

• Keep your hands and feet away from the working tool.

• Do not ‘ride’ on the machine with one leg over the handle, since you could be seriously injured if the tool were to break suddenly.

• Check regularly for wear to the working tool, and check whether there are any signs of damage or visible cracks. An incorrect dimension of the working tool’s shank can result in the working tool being lost or slipping out during operation. A working tool that is lost or slips out can cause personal injury.

• Before inserting the work tool, make sure that the shank’s dimensions are correct for use in the machine.

• Working tools without a collar may not be used. If the tool retainer on the machine is not in a locked position, the tool can be ejected with force, which can cause personal injury.

• Once the working tool has been mounted and locked, the locking function must be checked by pulling the working tool outwards forcefully.

• Make sure that the tool is fully inserted and the tool retainer is in the locked position before the machine is started.

• Never point the working tool at yourself or anyone else. Starting the machine while changing the working tool may cause personal injury.

• Do not perform any work on the machine, the connections or any hoses, when the hydraulic system is pressurized. NOTE!:- If the maximum working pressure for the machine is exceeded, the accumulator can be overcharged, which can result in material damage.

• Always run the machine with the correct working pressure. See “Technical Data” section.25 Safety Instructions Hydraulic Oil and Lubrication Hazards Thin jets of hydraulic oil under high pressure can penetrate the skin and cause permanent damage.

• Never use your hands when searching for oil leaks.

• Keep your face away from any possible leaks.

• Immediately seek medical attention if hydraulic oil has penetrated the skin. Spilled hydraulic oil can cause accidents by causing slippery conditions and will also harm the environment.

• Handle the hydraulic oil with care.

• Take care of all spilled oil and handle it according to your local safety and environmental regulations. Hot hydraulic oil can cause burns.

• Never dismount the machine when the hydraulic oil is hot. Hydraulic oil can cause eczema when it comes in contact with the skin.

• Avoid getting hydraulic oil on your hands.

• Always use protective gloves when working with hydraulic oil. Grease can cause eczema when it comes in contact with the skin.

• Avoid getting grease on your hands. Explosion and Fire Hazard Breaking, drilling and working with certain materials can cause sparks, which may ignite explosive gases and cause explosions. Explosions may cause serious injury or death. To reduce such risk of explosion:

• Never operate the machine in any explosive environment.

• 'RQRWXVHWKHPDFKLQHQHDUÀDPPDEOHPDWHULDOVIXPHVRUGXVW

• Make sure that there are no undetected sources of gas. Electrical/Concealed Object Hazards The machine is not electrically insulated. If the machine comes into contact with electricity, serious injuries or death may result.

• To reduce the risk of such injury or death, never operate the machine near any electric wire or other source of electricity.

• Make sure that there are no concealed wires or other sources of electricity. During breaking, concealed wires and pipes constitute a danger that can result in serious injury.

• Before you start breaking, check the composition of the material you are to work on.

• Watch out for concealed cables and pipes e.g. electricity, telephone, water, gas and sewage lines etc.

• ,IWKHWRROVHHPVWRKDYHKLWDFRQFHDOHGREMHFWVZLWFKR௺WKHPDFKLQHLPPHGLDWHO\

• Make sure that there is no danger before continuing. Projectile Hazard During breaking, drilling or hammering, splinters or other particles from the worked material may become projectiles and cause personal injury by striking the operator or other persons.

• Use approved personal protective equipment, including impact resistant safety glasses with side protection, to reduce the risk of being injured by a projectile. Noise Hazard High sound levels may cause permanent hearing loss.

• Use hearing protection in accordance with occupational health and safety regulations.26 Silica/Dust Hazard Exposure to crystalline silica (sometimes called ‘silica dust’) as a result of breaking, drilling, hammering, or other activities involving rock, concrete, asphalt or other materials may cause silicosis (a serious lung disease), silicosis-related illnesses, cancer, or death. Silica is a major component of rock, sand and mineral ores. To reduce silica exposure:

• Use proper engineering controls to reduce the amount of silica in the air and the build-up of dust on equipment and surfaces. Examples of such controls include: Exhaust ventilation and dust collection systems, water sprays, and wet drilling. Make sure that controls are properly installed and maintained.

• Wear, maintain, and correctly use approved particulate respirators when engineering controls alone are not adequate to reduce exposure below permissible levels.

• 3DUWLFLSDWHLQDLUPRQLWRULQJPHGLFDOH[DPVDQGWUDLQLQJSURJUDPVR௺HUHGE\\RXUHPSOR\HUDQGZKHQUHTXLUHGE\ODZ

• Wear washable or disposable protective clothes at the worksite; shower and change into clean clothes before leaving the worksite to reduce exposure of silica to yourself, other persons, cars, homes, and other areas.

• Do not eat, drink, or use tobacco products in areas where there is dust containing crystalline silica.

• Wash your hands and face before eating, drinking, or using tobacco products outside of the exposure area.

• Work with your employer to reduce silica exposure at your worksite. Some dust, fumes or other airborne material created during use of the machine may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of such chemicals are:

• Crystalline silica and cement and other masonry products.

• Arsenic and chromium from chemically-treated rubber.

• Lead from lead based paints. To reduce your exposure to these chemicals, work in a well ventilated area, and work with approved safety equipment, such as dust

• Use only original parts and accessories approved by Altrad Belle. Vibration Hazard Normal and proper use of the machine exposes the operator to vibration. Regular and frequent exposure to vibration may cause,

FRQWULEXWHWRRUDJJUDYDWHLQMXU\RUGLVRUGHUVWRWKHRSHUDWRU¶V¿QJHUVKDQGVZULVWVDUPVVKRXOGHUVDQGRURWKHUERG\SDUWV

including debilitating and/or permanent injuries or disorders that may develop gradually over periods of weeks, months, or years. Such injury or disorder may include damage to the blood circulatory system, damage to the nervous system, damage to joints, and possibly damage to other body structures. If numbness, tingling, pain, clumsiness, weakened grip, whitening of the skin, or other symptoms occur at any time, when operating the machine or when not operating the machine, do not resume operating the machine and seek medical attention. Continued use of the machine after the occurrence of any such symptom may increase the risk of symptoms becoming more severe and/or permanent. The following may help to reduce exposure to vibration for the operator:

• Let the tool do the job. Use a minimum hand grip consistent with proper control and safe operation.

• When the impact mechanism is activated, the only body contact with the machine you should have is your hands on the handles. Avoid any other contact, e.g. supporting any part of the body against the machine or leaning onto the machine trying to increase the feed force. It is also important not to keep the trigger engaged while extracting the tool from the broken work surface.

• Make sure that the inserted tool is wellmaintained (including sharpness, if a cutting tool), not worn out, and of the proper size. Working tools that are not well-maintained, or that are worn out, or that are not of the proper size result in longer time to complete a task (and a longer period of exposure to vibration) and may result in or contribute to higher levels of vibration exposure.

• ,PPHGLDWHO\VWRSZRUNLQJLIWKHPDFKLQHVXGGHQO\VWDUWVWRYLEUDWHVWURQJO\%HIRUHUHVXPLQJWKHZRUN¿QGDQGUHPRYHWKHFDXVH of the increased vibrations.

• Comply with the recommended hydraulic pressure when operating the machine. Either higher or lower hydraulic pressure has the potential of resulting in higher levels of vibration.

• Do not grab, hold or touch the inserted tool when using the machine.
