General Power Tool SafetyWarnings
WARNING
Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious
injury.
SAVE ALL WARNING AND INSTRUCTIONS FOR FUTURE REFERENCE
The term "power tool" in the warnings refers to your mains-operated (cored) power tool or battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or ground surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and / or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
Power tool use and care
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power 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.
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Demolition Hammer Safety Rules
Wear ear protectors. Exposure to noise can cause hearing loss.
Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold power tools by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could
give the operator an electric shock.
Use a metal detector to determine if there are gas or water pipes hidden in the work area or call the local utility company for assistance before beginning the operation. Striking or cutting into a gas line will result in explosion. Water entering an electrical device may cause electrocution.
Always wear safety goggles or eye protection when using this tool. Use a dust
mask or respirator for applications which generate dust. Safety goggles or eye protection will help deflect fragments of the material that may be thrown toward your face and eyes. Dust generated or gases released from the material you are cutting (i.e. asbestos insulated pipes, radon) may cause respiratory difficulties.
Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by hammer action may be harmful to your hands and arms.
Do not use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to bind in the workpiece.
Always use both handles for maximum control over this hammer. Never attempt to operate this tool with one hand. This tool develops intense percussive forces during
operation and you may lose control if attempting one hand operation.
Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or jammed in the work, the reaction of the tool could crush your hand or leg.
Do not strike the bit with a handheld hammer or sledge hammer when attempting to dislodge a bound or jammed bit. Fragments of metal from the bit could dislodge and strike you or bystanders.
Never place the tool down until the motor has come to a complete stop.
When removing the bit from the tool avoid contact with skin and use proper protective gloves when grasping the bit or accessory. Accessories may be hot after prolonged use.
Additional SafetyWarnings
GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety.
Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.
Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.
Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted.
Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
Risk of injury to user. The power cord must only be serviced by a Bosch Factory Service Center or Authored Bosch Service Station.
WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
- Lead from lead-based paints,
- Crystalline silica from bricks and cement and other masonry products, and
- Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Functional Description and Specifications
WARNING
Disconnect the plug from the power source before making any assembly, adjustments or changing accessories. Such preventive
safety measures reduce the risk of starting the tool accidentally.
Demolition Hammer
FIG.2
NOTE: For tool specifications refer to the nameplate on your tool.
Assembly
AUXILIARY HANDLE
The tool must be supported with the auxiliary handle, which can be swiveled 360^ . To reposition and/or swivel the handle, loosen the hand grip, move the handle to the desired position along the barrel and securely retighten the hand grip (Fig. 3).
INSTALLING ACCESSORIES
Clean the insert shank end of the accessory to remove any debris, then lightly grease with a light oil or lubricant.
Insert accessory into the tool holder through the dust shield, while twisting and pushing inward until it locks automatically into place. Pull outward on the accessory to be certain it is locked into the tool holder (Fig. 4).
NOTE: The high efficiency available from the hammers can only be obtained if sharp and undamaged accessories are used. The "cost"
to maintain sharp and undamaged accessories is more than offset by the "time saved" in operating the tool with sharp accessories.
REMOVING ACCESSORIES
WARNING Accessories may be hot after use. Avoid contact with skin and use proper protective gloves or cloth to remove.
To remove an accessory, pull locking sleeve backward and pull bit forward. All accessories should be wiped clean after removing (Fig. 5).
Operating Instructions
TRIGGER "ON-OFF" SWITCH
Your tool is equipped with a "Lock-ON" feature which allows continuous operation without holding the trigger.
TO LOCK TOOL "ON":squeeze the trigger switch until it locks (Fig. 6).
TO TURN TOOL: "OFF" press the trigger release switch and the trigger will return to the "OFF" position automatically (Fig. 6).
To increase switch life, do not turn switch on and off while tool is under load.
AUTO-MAXTM
The patented Bosch Auto-Max system insures that each time your tool is plugged in and receiving power, it will operate at maximum speed and impact force.
△WARNING
When the power cord is unplugged from the
mains outlet or when branch-circuit power is interrupted, the electronic controller will automatically reset the tool to maximum speed and impact force. Unexpected starting at maximum operating speed and impact force could startle the operator and lead to potential injury.
"VARIO-LOCK"-SELECTOR RING
The vario-lock selector ring can be set in any one of twelve (30^ increments) positions. Choose a position which is best suited for your operation. To adjust, pull the selector ring forward and hold firmly, then turn both the accessory and the selector ring to the desired position. Release the selector ring and turn the accessory slightly until it locks in place (Fig. 7).
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed dial. The speed and impact force can be adjusted by rotating the dial. Higher speeds and impact force work best for faster penetration when chiseling in hard masonry material. Slower speeds work best for chiseling material such as plaster or tile (Fig. 8).
CONSTANT RESPONSE CIRCUITRY
The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also helps to keep the pre-selected impact rate virtually constant between no-load and load conditions.
POWER INDICATOR LIGHT
When you plug your tool into the power source, the power indicator light will go "ON" indicating the tool is receiving power (Fig. 8).
VIBRATION DAMPER HANDLE / HAMMER MECHANISM
The integrated vibration damper in the main handle and hammer mechanism reduces vibrations (Fig. 8).
Tool Tips
For the best penetration rates in concrete, run the tool with a steady pressure, but do not use excessive force as this will decrease the efficiency of the tool.
All hammers require a short period of time to warm up. Depending on the room temperature, this time may vary from approximately 15 seconds (90^) to 2 minutes (32^) . A new hammer requires a break-in period before full performance is realized. This period may require up to 5 hours of operation.
An electric hammer is likely to be the most expensive portable tool at the construction job. The long wear and efficient operation of the BOSCH hammers will more than justify the cost for tools of this type. As earlier pointed out, sharp accessories as well as clean air vents are necessary for efficient operation. Establish and follow a set maintenance program.
Dust Extraction
For selection of dust collection systems and operating instructions, see the Operating / Safety Instructions for 'Dust Extraction
Attachments for Hammers and Hammer Drills' included with your tool or with the dust extraction attachment.
Maintenance
Service
WARNING
Preventive maintenance performed by unauth -
orized per so n nel may result in misplacing of internal wires and components which could cause serious hazard. We
recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station.
SERVICE REMINDER LIGHT
When the service reminder light lights up or blinks, this will indicate that the cut-out carbon brushes will switch off the tool in approximately 8 hours. After that period, the light will go off and the tool will stop running. The tool must then be sent to a service center for service (Fig. 8).
TOOL LUBRICATION
Your Bosch tool has been properly lubricated and is ready to use. It is recommended that tools with gears be regreased with a special gear lubricant at every brush change.
CARBON BRUSHES
The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brush es be examined. Only genuine Bosch replacement brushes specially designed for your tool should be used.
BEARINGS
After about 300-400 hours of operation, or at every second brush change, the bearings
should be replaced at Bosch Factory Service Center or Au thorized Bosch Service Station. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating or motor failure.
REPLACEMENT OF CORD AND CARBON BRUSHES
Your tool is designed to provide a qualified service technician optimal access to replace the carbon brushes and the cord. This provides the service technician the ability to replace these components without the need of disassembling the entire tool housing.
Cleaning
WARNING
To avoid accidents always dis connect the
tool from the power supply before cleaning or performing any main tenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air.
Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not atempt to clean by inserting pointed objects through openings.
CAUTION
Certain cleaning agents and sol vents damage
plastic parts. Some of these are: gasoline, carbon tetrachloride, chlo rinated cleaning solvents, ammonia and house hold detergents that contain ammonia.
Extension Cords
WARNING
If an extension cord is necessary, a cord with
adequate size conductors that is capable of carrying the current necessary for your tool must be used. This will prevent excessive voltage drop, loss of power or overheating. Grounded tools must use 3-wire extension cords that have 3-prong plugs and receptacles.
NOTE: The smaller the gauge number, the higher the cord capacity.
