Safety Information

• Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
• Save all warnings and instructions for future reference.
• The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

General Safety Warnings

• 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 that can ignite the dust or fumes.
• Keep children and bystanders away from the work area. Distractions can cause you to lose control of the power tool.
• Do not use the power tool if 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 (PPE) such as dust mask, non-slip safety shoes, hard hat, safety glasses with side shields, and hearing protection. The type of PPE required will vary depending on the specific power tool operation.
• Prevent unintentional starting. Ensure the switch is in the "off" position before connecting to the power source and/or inserting the battery. Carrying the power tool with your finger on the switch or connecting the power tool to the power source while it is switched on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or key that is 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 will enable 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 clothing, jewelry, or long hair can be caught in moving parts.
• Use the correct power tool for the job. Do not force a power tool to do a job for which it was not designed. Use the correct power tool for the specific application.
• Do not use the power tool if the switch does not turn it on and off properly. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the power tool from the power source and/or remove the battery pack before making any adjustments, changing accessories, or storing the power tool. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store power tools out of the reach of children and other untrained persons. Power tools are dangerous in the hands of untrained users.

Additional Safety Warnings for Rotary Hammers

• Use only inserts and accessories that are designed for your specific rotary hammer. Using the wrong insert or accessory can increase the risk of personal injury.
• Hold the rotary hammer firmly with both hands when operating it. Do not allow the rotary hammer to contact the ground or other objects when it is running. This could cause the rotary hammer to become uncontrollable and could result in personal injury.
• Use the correct drill bit for the material you are drilling. Using the wrong drill bit could cause the drill bit to break, which could result in personal injury.
• Do not overload the rotary hammer. If the rotary hammer begins to slow down, reduce the pressure on the trigger. Overloading the rotary hammer can cause it to overheat and could result in personal injury.
• Do not use the rotary hammer in wet or damp conditions. This could increase the risk of electric shock.

Before Use

• Read the entire instruction manual before using the rotary hammer.
• Make sure the rotary hammer is properly assembled.
• Check the condition of the rotary hammer before each use. Inspect the power cord for any damage, and make sure the switch operates properly.
• Use only the batteries and chargers that are recommended by Bosch.
• Do not use the rotary hammer if it is damaged.

Troubleshooting

• If the rotary hammer does not start, check the battery charge. If the battery is fully charged, check the switch to make sure it is in the "on" position.
• If the rotary hammer stops working while in use, check the power cord for any damage. If the power cord is damaged, replace it.
• If the rotary hammer overheats, stop using it and allow it to cool down.

Maintenance
