OBJ_BUCH-2092-002.book Page 11 Thursday, February 23, 2017 11:46 AM12 | English 1 609 92A 33X | (23.2.17) Bosch Power Tools English Safety Notes General Safety Rules for Pneumatic Tools Before installing, operating, repairing, maintaining and replacing accessories as well as prior to working near by the pneumatic tool, please read and observe all instructions. Failure to follow the following safety warnings may result in serious injury. Save all safety warnings and instructions for future refer- ence, and make them available to the operator. Work area safety Pay attention to surfaces that may have become slip- pery from using the machine, and to tripping hazards from the pneumatic or hydraulic hose. Slipping, tripping and falling are main reasons for workplace injuries. Do not operate the pneumatic tool in explosive atmos- pheres, such as in the presence of flammable liquids, gases or dusts. While working the workpiece, sparks can be created which may ignite the dust or fumes. Keep children and bystanders away from your work- place while operating the pneumatic tool. Distractions from other persons can cause you to lose control over the pneumatic tool. Pneumatic tool safety Never direct the airflow against yourself or other per- sons close by, and conduct cold air away from your hands. Compressed air can lead to serious injuries. Check the connections and the air supply lines. All maintenance units, couplers, and hoses should conform to the product specifications in terms of pressure and air vol- ume. Too low pressure impairs the function of the pneu- matic tool; too high pressure can result in material damage and personal injury. Protect the hoses from kinks, restrictions, solvents, and sharp edges. Keep the hoses away from heat, oil, and rotating parts. Immediately replace a damaged hose. A defective air supply line may result in a wild com- pressed-air hose and can cause personal injury. Raised dust or chips may cause serious eye injury. Make sure that hose clamps are always tightened firm- ly. Loose or damaged hose clamps may result in uncon- trolled air escape. Personal safety Stay alert, watch what you are doing, and use common sense when operating a pneumatic tool. Do not use a pneumatic tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating a pneumatic tool may result in personal in- jury. Use personal protective equipment. Always wear eye protection. Wearing personal protective equipment – such as a respirator, non-skid safety shoes, hard hat or hearing protection – according to the instructions of your employer or as required by the provisions for work and health protection, reduces the risk of personal injury. Prevent unintentional starting. Make sure that the pneumatic tool is switched off before connecting it to the air supply, picking it up or carrying it. When your fin- ger is on the On/Off switch while carrying the pneumatic tool or when connecting the pneumatic tool to the air sup- ply while it is switched on, accidents can occur. Remove any adjustment tools before switching on the pneumatic tool. A wrench or key left attached to a rotating part of a pneumatic tool may result in personal injury. Do not overreach. Keep proper footing and balance at all times. This enables better control of the pneumatic tool in unexpected situations. Dress properly. Do not wear loose clothing or jewel- lery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. If devices are provided for the connection of dust ex- traction and collection facilities, ensure these are con- nected and properly used. Use of dust collection can re- duce dust-related hazards. Do not directly inhale the exhaust air. Avoid exposing the eyes to exhaust air. The pneumatic tool’s exhaust air can contain water, oil, metal particles and debris from the compressor. This can cause damage to one’s health. Pneumatic tool use and care Use the clamping devices or a vice to secure and sup- port the workpiece. Holding the workpiece by hand or against your body will not allow for safe operation of the pneumatic tool. Do not overload the pneumatic tool. Use the pneumatic tool intended for your work. The correct pneumatic tool will do the job better and safer at the rate for which it is de- signed. Do not use a pneumatic tool that has a defective On/Off switch. A pneumatic tool that cannot be controlled with the switch is dangerous and must be repaired. Disconnect the air supply before making any adjust- ments, changing accessories, or when not using for ex- tended periods. This safety measure prevents accidental starting of the pneumatic tool. Store idle pneumatic tools out of the reach of children. Do not allow persons unfamiliar with the pneumatic tool or these instructions to operate the device. Pneu- matic tools are dangerous in the hands of untrained users. Maintain the pneumatic tool with care. Check for mis- alignment or binding of moving parts, breakage of parts and any other condition that may affect the pneu- matic tool’s operation. Have damaged parts repaired before using the pneumatic tool. Many accidents are caused by poorly maintained pneumatic tools. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. WARNING OBJ_BUCH-2092-002.book Page 12 Thursday, February 23, 2017 11:46 AMEnglish | 13 Bosch Power Tools 1 609 92A 33X | (23.2.17) Use the pneumatic tool, accessories, application tools, etc. according to these instructions. Take into consid- eration the working conditions and the activities to be carried out. This reduces the development of dust, vibra- tions and noise to the greatest extent. The pneumatic tool should be set up, adjusted or used exclusively by qualified and trained operators. The pneumatic tool may not be modified in any way. Modifications can reduce the effectivity of the safety measures and increase the risks for the operator. Service Have your pneumatic tool repaired only through a qual- ified repair person and only using original replacement parts. This will ensure that the safety of the pneumatic tool is maintained. Safety Warnings for Pneumatic Rotary Hammers Check if the type plate can be read. If required, provide for replacement from the manufacturer. In case of breakage of the workpiece or an accessory, or even of the pneumatic tool itself, parts can be thrown about at high speed. During operation, repairs or maintenance, and when replacing accessories on the pneumatic tool, always wear shock-resistant eye protection. The degree of the required protection should be separately evaluated for each individual application. Wear a hard hat when carrying out work overhead. This prevents injuries. Use the pneumatic tool only when the chisel is secured against falling out. Otherwise, the application tool can be thrown about. Worn, bent or broken parts of the tool holder must be replaced. This prevents injuries. Apply the pneumatic tool firmly to the surface to be worked before switching the pneumatic tool on. The operators and the maintenance personnel must be physically capable to handle the size, weight and pow- er of the pneumatic tool. Be prepared for unexpected movements of the pneu- matic tool that can develop owing to reaction forces or breakage of the application tool. Maintain a firm grip on the pneumatic tool and position your body and arms to allow you to resist such movements. These precau- tions can prevent injuries. Caution! Application tools can become hot during pro- longed operation of the pneumatic tool. Wear protective gloves. In case of an interruption of the air supply or reduced operating pressure, switch the pneumatic tool off. Check the operating pressure and start again when the op- erating pressure is optimal. When using the pneumatic tool for the performance of work-related activities, the operator may experience unpleasant sensations in the hands, arms, shoulders, neck area or other body parts. When working with this pneumatic tool, assume a com- fortable stance, hold the tool securely and avoid unfa- vourable positions or such positions, where it is diffi- cult to keep your balance. For prolonged work, the operator should change the stance or posture, which can help avoid discomfort and fatigue. Should the operator perceive symptoms such as persis- tent nausea, discomfort, throbbing, pain, tingling, numbness, burning or stiffness, these warning signs should not be ignored. The operator should notify his employer about the symptoms and consult a qualified physician. Never use the chisel as a hand tool. The chisels are heat- treated and can break. Use only sharp chisels. Dull application tools can lead to heavy vibrations and fatigue breakage. Never cool off hot accessories in water. This can lead to brittleness and premature failure. Do not use the chisel as a lever. Otherwise, it can break. Use appropriate detectors to determine if utility lines are hidden in the work area or call the local utility com- pany for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property dam- age. Avoid contact with “live” conductors. The pneumatic tool is not insulated; contact with a “live” conductor can lead to an electric shock. The dust developing during sanding, sawing, grinding, drilling and similar operations can act carcinogenic, teratogenic or mutagen- ic. Some of the substances contained in these dusts are: – Lead in lead-based paints and varnishes; – Crystalline silica in bricks, cement and other masonry work; – Arsenic and chromate in chemically treated wood. The risk of disease depends on how often you are ex- posed to these substances. To reduce the risk, you should work only in well ventilated rooms with appropriate protec- tive equipment (e. g. with specially designed respirators that filter out even the smallest dust particles). When working on the workpiece, additional noise can develop, which can be avoided through appropriate measures (e. g. by using damping materials on occur- rence of ringing noise from the workpiece). Operate the pneumatic tool in such a manner that as lit- tle dust as possible develops, e. g. through moistening the material being worked. When the pneumatic tool is equipped with a silencer, always ensure that it is available and in proper working condition when operating the pneumatic tool. Vibration effects may cause damage to the nerves and blood circulation disorders in the hands and arms. Wear close-fitting gloves. The flow of compressed air makes the handles of pneumatic tools cold. Warm hands are less sensitive to vibrations. Loose fitting gloves can be caught by rotating parts. WARNING OBJ_BUCH-2092-002.book Page 13 Thursday, February 23, 2017 11:46 AM14 | English 1 609 92A 33X | (23.2.17) Bosch Power Tools If you notice that the skin of your fingers or hands be- comes numb, tingles, hurts or turns white, stop work- ing with the pneumatic tool, notify your employer and consult a physician. Do not hold the application tool while working. Hold the pneumatic tool with a not too firm yet secure grip, compliant with the required hand-reaction forces. The vibrations can be intensified the firmer you hold the tool. When universal rotary couplings (bayonet couplings) are being used, retaining pins are required. Use Whip- check hose restraints to protect against failed hose connections or the connection between hose and pneu- matic tool. Never carry the pneumatic tool by the hose. Switch the pneumatic tool off immediately when the application tool locks up. Be prepared for high reaction torque that lead to kickback. The application tool locks- up when: – the pneumatic tool is subject to overload, – it jams or cants in the workpiece or – its tip goes through the material being worked. Use auxiliary aids to absorb reaction torque, such as a supporting fixture. If this is not possible, use an auxilia- ry handle. Never place your hand near rotating application tools. You could injure yourself. Do not allow the drill bit to rattle on the workpiece. This can lead to significant intensification of the vibrations. Symbols The following symbols could have a meaning for the use of your pneumatic tool. Please take note of the symbols and their meaning. The correct interpretation of the symbols will help you to use the pneumatic tool in a better and safer man- ner.

Declaration of Conformity We declare under our sole responsibility that the product de- scribed under “Technical Data” is in conformity with the fol- lowing standards or standardization documents: EN ISO 11148 according to the provisions of the directive 2006/42/EC. Technical file (2006/42/EC) at: Robert Bosch Power Tools GmbH, PT/ECS, 70538 Stuttgart, GERMANY Robert Bosch Power Tools GmbH70538 Stuttgart, GERMANYStuttgart, 01.01.2017 Assembly Auxiliary Handle (see figure A) For safety reasons, the pneumatic tool must only be used with mounted auxiliary handle 10. The auxiliary handle 10 can be set to any position for a secure and low-fatigue working posture. – Turn the wing bolt for adjustment of the auxiliary handle 4 in anticlockwise direction and set the auxiliary handle 10 to the required position. Then tighten the wing bolt 4 again in clockwise direction. Exhaust-air Guidance With exhaust-air guidance, the exhaust air can be diverted through an exhaust-air hose away from your workplace, while at the same time achieving optimal sound-proofing. Addition- ally, your working conditions are improved, as your workplace can no longer be contaminated though oil-containing air and dispersed dust or chips. – Unscrew the silencer at air outlet 8 and replace it with a hose fitting 9. – Loosen hose clamp 12 of the exhaust-air hose , mount the exhaust-air hose to hose fitting 9 and retighten the hose clamp. Connecting the Air Supply (seefigure B) Ensure that the air pressure is not lower than 5 bar (72.5 psi) because the pneumatic tool is designed for this operating pressure. For maximum performance, the values for the inner hose di- ameter as well as the connection threads must be adhered to as listed in the “Technical Data” Table. To maintain the full performance, only use hoses with a maximum length of 4 m. The compressed air supplied should be free of foreign materi- al and moisture to protect the tool from damage, contamina- tion, and the formation of rust. Note: The use of a compressed-air maintenance unit is neces- sary. This ensures proper function of the pneumatic tools. Observe the operating instructions of the maintenance unit. All fittings, connecting lines and hoses must be dimensioned for the pressure and the required air volume. Pneumatic rotary hammer Article number 0 607 557 501 Rotational speed under load, max. min

When in doubt, check the pressure at the air inlet with a pres- sure gauge with the pneumatic tool switched on. Connecting the Air Supply to the Pneumatic Tool – Screw hose fitting 9 into the connection socket at air inlet

To avoid damage to interior valve components of the pneu- matic tool when screwing hose fitting 9 in or out, it is rec- ommended to counter-hold the projecting connection socket of air intake 7 with an open-end wrench (size 22 mm). – Loosen hose clamp 12 of supply-air hose 13, mount the supply-air hose to hose fitting 9 and retighten the hose clamp. Note: Always mount the supply-air hose to the pneumatic tool first, then to the maintenance unit. Selecting Drill Chucks and Tools For hammer drilling and chiselling (chiselling only with MV 200 accessory), SDS-plus tools are required that are in- serted in the SDS-plus drill chuck. For drilling without impact in wood, metal, ceramic and plas- tic as well as for screwdriving, tools without SDS-plus are used (e.g., drills with cylindrical shank). For these tools, a keyless chuck or a key type drill chuck are required. Changing the Key Type Drill Chuck To work with tools without SDS-plus (e.g., drills with cylindri- cal shank), a suitable drill chuck must be mounted (key type drill chuck or keyless chuck, accessories). Mounting the Key Type Drill Chuck (see figure C) – Screw the SDS-plus adapter shank 16 into a key type drill chuck 15. Secure the key type drill chuck 15 with the se- curing screw 14. Please observe that the securing screw has a left-hand thread. Inserting the Key Type Drill Chuck (see figure D) – Clean the shank end of the adapter shank and apply a light coat of grease. – Insert the key type drill chuck with the adapter shank into the tool holder with a turning motion until it automatically locks. – Check the locking effect by pulling the key type drill chuck. Removing the Key Type Drill Chuck – Push the locking sleeve 3 toward the rear and pull out the key type drill chuck 15. Changing the Tool The dust protection cap 2 largely prevents the entry of drilling dust into the tool holder during operation. When inserting the tool, take care that the dust protection cap 2 is not damaged. A damaged dust protection cap should be changed im- mediately. We recommend having this carried out by an after-sales service. Inserting SDS-plus Drilling Tools (see figure E) The SDS-plus drill chuck allows for simple and convenient changing of drilling tools without the use of additional tools. – Clean and lightly grease the shank end of the tool. – Insert the tool in a twisting manner into the tool holder until it latches itself. – Check the latching by pulling the tool. As a requirement of the system, the SDS-plus drilling tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centres itself upon drilling. Removing SDS-plus Drilling Tools (see figure F) – Push back the locking sleeve 3 and remove the tool. Inserting Drilling Tools without SDS-plus Note: Do not use tools without SDS-plus for hammer drilling or chiselling! Tools without SDS-plus and their drill chucks are damaged by hammer drilling or chiselling. – Insert a key type drill chuck 15 (see “Changing the Key Type Drill Chuck”, page 16). – Open the key type drill chuck 15 by turning until the tool can be inserted. Insert the tool. – Insert the chuck key into the corresponding holes of the key type drill chuck 15 and clamp the tool uniformly. Removing Drilling Tools without SDS-plus – Turn the sleeve of the key type drill chuck 15 with the drill chuck key in anticlockwise direction until the drilling tool can be removed. Operation Starting Operation The pneumatic tool works optimally at a working pressure of 5 bar (72.5 psi), measured at the air inlet when the pneumat- ic tool is switched on. Setting the operating mode The operating mode of the pneumatic tool is selected using the mode selector switch 5. Note: Change the operating mode only when the pneumatic tool is switched off! Otherwise, the pneumatic tool may be- come damaged. – Turn the mode selector switch 5 to the requested position.

Working Advice Sudden loads cause a sharp drop in speed or a complete stop, yet do not cause damage to the motor. Adjusting the Depth Stop (see figure G) The required drilling depth X can be set with the depth stop

– Loosen the wing bolt 4 on the auxiliary handle 10. – Pull out the depth stop until the distance between the tip of the drill bit and the tip of the depth stop correspond with the desired drilling depth X. – Tighten the wing bolt again. Maintenance and Service Maintenance and Cleaning Have maintenance and repair work carried out only through qualified persons. This will ensure that the safe- ty of the pneumatic tool is maintained. An authorized Bosch after-sales service agent will carry out this work quickly and reliably. Regular Cleaning – Clean the sieve at the air intake of the pneumatic tool regu- larly. For this, unscrew the hose fitting 9 and remove any dust and debris from the sieve. Afterwards, retighten the hose fitting again. – Water and debris particles in the compressed air cause rust and lead to wear of plates, valves etc. To prevent this, fill several drops of engine oil into the air intake 7. Recon- nect the pneumatic tool to the air supply (see “Connecting the Air Supply”, page 15) and run it for 5 –10 seconds, while catching/picking up the escaping oil with a cloth. Al- ways carry out this procedure when not using the pneu- matic tool for a longer period of time. Scheduled Maintenance – Clean the gearbox after the first 150 running hours using a mild solvent. Follow the solvent manufacturers directions for use and disposal. Lubricate the gearbox using Bosch gearbox lube. Repeat the lubrication procedure every 300 hours after the initial gearbox service. Special gearbox grease (225 ml) Article number 3 605 430 009 – The motor plates should be checked regularly by special- ised personnel and replaced, if required. Lubrication of Pneumatic Tools that do not belong to the CLEAN Product Line For all Bosch pneumatic tools that do not belong to the CLEAN product line (these have a special type of compressed-air mo- tor that functions with oil-free compressed air), oil mist should be added continuously to the flowing-through com- pressed air. The compressed-air oiler required for this is in- cluded in the compressed-air service unit on the line side of the pneumatic tool (for more details, please refer to the com- pressor manufacturer). For direct lubrication of the pneumatic tool or admixtures to the service unit, use SAE 10 or SAE 20 engine oil.
