Safety Notes

General Power Tool Safety Warnings

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 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.

Work area safety

Keep the 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 may ignite 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 the risk of electric shock.
Avoid body contact with earthed or grounded 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, and 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.
The 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 residual current device (RCD) protected supply. The use of an RCD 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 a 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 a 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 jewellery. 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.

Battery tool use and care

Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
Use power tools only with specifically designated battery packs. The use of any other battery packs may create a risk of injury and fire.
When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

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.

Safety Warnings for Drills and Screwdrivers

Hold power tool by insulated gripping surfaces when performing an operation where the cutting accessory or fastener may contact hidden wiring. Cutting accessory and fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold the machine with a firm grip. High reaction torque can briefly occur while driving in and loosening screws.
Use appropriate detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage.
Switch off the power tool immediately when the tool inserts jams. Be prepared for high reaction torque that can cause kickback. The tool insert jams when: — the power tool is subject to overload or — it becomes wedged in the workpiece.
Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Do not open the battery. The danger of short-circuiting.

Protect the battery against heat, e. g., against continuous intense sunlight, fire, water, and moisture. The danger of explosion.

In case of damage and improper use of the battery, vapors may be emitted. Ventilate the area and seek medical help in case of complaints. The vapors can irritate the respiratory system.
Use the battery only in conjunction with your Bosch power tool. This measure alone protects the battery against dangerous overload.
The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit can occur and the battery can burn, smoke, explode or overheat.

Noise/Vibration Information
Sound emission values were determined according to EN 60745-2-1.
Typically the A-weighted sound pressure level of the product is 66 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 80 dB(A).
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 60745-2-1:
Screwdriving without impact: ah <2.5m/s 2 2 , K=1.5 m/s
Drilling into metal: ah <2.5m/s 2 2 , K=1.5 m/s

The vibration level given in this information sheet has been measured in accordance with a standardized test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different accessories or insertion tools, or is poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintaining the tool and the accessories, keeping the hands warm, organization of work patterns

Assembly

Battery Charging (see figure A)

Note: The battery supplied is partially charged. To ensure full capacity of the battery, completely charge the battery in the battery charger before using your power tool for the first time.
The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery.
The lithium-ion battery is protected against deep discharging by the “Electronic Cell Protection (ECP)”. When the battery is empty, the machine is switched off by means of a protective circuit: The inserted tool no longer rotates.

Do not continue to press the On/Off switch after the machine has been automatically switched off. The battery can be damaged. To remove the battery 5 press the unlocking buttons 4 and pull out the battery downwards. Do not exert any force. Observe the notes for disposal. Changing the Tool (see figure B)
Before any work on the machine itself (e. g. maintenance, tool change, etc.) as well as during transport and storage, remove the battery from the power tool. There is a danger of injury when unintentionally actuating the On/Off switch.
The drill spindle is locked when the On/Off switch 7 is not pressed. This makes quick, convenient, and easy changing of the tool in the drill chuck possible.
Open the keyless chuck 1 by turning in the rotation direction 1, until the tool can be inserted. Insert the tool. Firmly tighten the collar of the keyless chuck 1 by hand in rotation direction 2.

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some wood types, minerals, and metal can be harmful to one’s health. Touching or breathing in the dust can cause allergic reactions and/or lead to respiratory infections in the user or bystanders. Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the materials to be worked.
Prevent dust accumulation at the workplace. Dust can easily ignite.

Operation

Starting Operation
Inserting the battery

Use only original Bosch lithium-ion batteries with the voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire hazard.

Note: Use of batteries not suitable for the machine can lead to malfunctions of or cause damage to the power tool.
Set the rotational direction switch 6 to the center position in order to avoid unintentional starting. Insert the charged battery 5 into the handle so that it can be felt to engage and faces flush against the handle.
Reversing the rotational direction (see figure C)
The rotational direction switch 6 is used to reverse the rotational direction of the machine. However, this is not possible with the On/Off switch 7 actuated.
Right Rotation: For drilling and driving in screws, push the rotational direction switch 6 left to the stop.
Left Rotation: For loosening and unscrewing screws and nuts, press the rotational direction switch 6 through to the right stop.
Setting the torque
With the torque presetting ring 2 the required torque setting can be preselected in 20 steps. With the correct setting, the insert tool is stopped as soon as the screw is screwed flush into the material or when the adjusted torque is reached. The safety clutch is deactivated in the “ ” position, e. g. for drilling.
Select a higher setting or switch to the “ ” symbol when un- screwing screws.
Gear selection, mechanical

Actuate the gear selector 3 only when the machine is at a standstill.

Two-speed ranges can be preselected with the gear selector 3.
Gear I: Low-speed range; for screwdriving or working with large drilling diameter.
Gear II: High-speed range; for working with small drilling diameter.
If the gear selector 3 cannot be pushed through to the stop, lightly turn the tool holder 1 with the insert tool.

Switching On and Off
To start the machine, press the On/Off switch 7 and keep it pressed.
The power light 8 lights up when the On/Off switch 7 is slightly or completely pressed and allows the work area to be illuminated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 7. To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably adjusted, depending on how far the On/Off switch 7 is pressed.
Light pressure on the On/Off switches 7 results in a low rotational speed. Further pressure on the switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 7 is not pressed, the drill spindle and thus the tool holder is locked.
This enables screws to be screwed in, even when the battery is empty, and allows for the machine to be used as a screwdriver.
Run-on Brake
When the On/Off switch 7 is released, the chuck brakes to a stop, thus preventing the run-on of the tool.
When driving in screws, wait until the screw is screwed in flush with the material and then release the On/Off switch 7. By doing so, the head of the screw does not penetrate into the material.
Temperature-Dependent Overload Protection
When used as intended, the power tool cannot be subject to overload. When the load is too high or the allowable battery temperature range is exceeded, the speed is reduced. The power tool will not run at full speed until reaching the allowable battery temperature.
Working Advice

Apply the power tool to the screw only when it is switched off. Rotating tool inserts can slip off.

After longer periods of working at low speed, allow the machine to cool down by running it for approx. 3 minutes at maximum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill bits (HSS=high- speed steel). The appropriate quality is guaranteed by the Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is advisable to predrill a pilot hole with the core diameter of the thread to approx. 2 /3 of the screw length.

Maintenance and Service

Before any work on the machine itself (e. g. maintenance, tool change, etc.) as well as during transport and storage, remove the battery from the power tool.
There is a danger of injury when unintentionally actuating the On/Off switch.
For safe and proper working, always keep the machine and ventilation slots clean.

When the battery is no longer operative, please refer to an authorized after- sales service agent for Bosch power tools.
