Noise/Vibration Information

Measured sound values determined according to EN 60745. Typically the A-weighted sound pressure level of the product is 75 dB(A). Uncertainty K = 3 dB. The noise level when working can exceed 80 dB(A). Wear hearing protection!

Vibration total values a₁ (triax vector sum) and uncertainty K determined according to EN 60745:

Screwdriving without impact: aħ < 2.5 m/s², K = 3 m/s².

The vibration emission level given in this information sheet has been measured in accordance with a standardised 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 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: maintain the tool and the accessories, keep hands warm, organise work patterns.

Assembly

Battery Charging

• Use only the battery chargers listed on the accessories page. Only these battery chargers are matched to the lithium ion battery of your power tool.

Note: The battery is supplied 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.

The battery is equipped with a NTC temperature control which allows charging only within a temperature range of between 0 °C and 45 °C. A long battery service life is achieved in this manner.

Observe the notes for disposal.

Removing the battery

The battery 9 is equipped with two locking levels that should prevent the battery from falling out when pushing the battery unlocking button 10 unintentionally. As long as the battery is inserted in the power tool, it is held in position by means of a spring.

1. To remove the battery 9, press the unlocking button 10 and pull out the battery toward the front. Do not exert any force.

Changing the Tool (see figure A)

• 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 danger of injury when unintentionally actuating the On/Off switch.
• Pull off the screwing-depth stop 4 toward the front. Pull out the screwdriver bit 1. If required, the universal bit holder 13 can also be pulled off and replaced.
• After changing the tool, reattach the screwing-depth stop 4.

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 5 to the centre position in order to avoid unintentional starting. Insert the charged battery 9 into the handle so that it can be felt to engage and faces flush against the handle.

Reversing the rotational direction

The rotational direction switch 5 is used to reverse the rotational direction of the machine. However, this is not possible with the On/Off switch 7 actuated.

• Rotate clockwise: Move the rotational direction switch 5 on both sides up to the stop into position ▶️
• Rotate anticlockwise: Move the rotational direction switch 5 on both sides up to the stop into position ◀️

Switching On and Off

To start the machine, press the On/Off switch 7 and keep it pressed.

The LED 12 lights up when the On/Off switch 7 is halfway or fully pressed, and enables illumination of the screwing location in unfavourable light conditions.

To lock the pressed On/Off switch 7, press the lock-on button 6.

To switch off the machine, release the On/Off switch 7 or when it is locked with the lock-on button 6, briefly press the On/Off switch 7 and then release it.

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 switch 7 results in a low rotational speed. Further pressure on the switch results in an increase in speed.

Adjusting the Screw-in Depth (see figure B)

With the adjustment sleeve 3, the screw-in depth of the screw head into the workpiece can be preset in 8 locking steps per full turn. Each step corresponds with a 0.25 mm change of the screw-in depth.

Turning the adjustment sleeve 3 in clockwise direction results in a greater screw-in depth; turning in anticlockwise direction reduces the screw-in depth.

The required setting is best determined by testing.

Temperature Dependent Overload Protection

When using as intended for, the power tool cannot be subject to overload. When the load is too high or the allowable battery temperature range of 0-70 °C is exceeded, the speed is reduced. The power tool will not run at full speed until reaching the allowable battery temperature.

Protection Against Deep Discharging

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.

Working Advice

• Apply the power tool to the screw only when it is switched off. Rotating tool inserts can slip off.
• Guide the screw toward the screwdriving bit 1. The screw is held in place by the magnet pull of the universal bit holder 13.
• Firmly push the tip of the screw into the material to be screwed until the screwing-depth stop 4 faces against the workpiece.
• Switch the machine on. The screw is screwed into the material until the adjusted screw-in depth is reached. The drive is disengaged and the tool holder no longer rotates. Check the screw-in depth and readjust, if required.
• For unscrewing screws, set the rotational direction switch 5 to left rotation and pull off the screwing-depth stop 4 toward the front without turning the adjustment sleeve.

Working with the screwing-depth stop 4 is also possible when adapting the screw-in depth.

Belt Clip

With the belt clip 8, the machine can be hung onto a belt. The user has both hands free and the machine is always at hand.
