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.

Reversing the rotational direction (see figure C)

The rotational direction switch 4 is used to reverse the rota-

tional direction of the machine. However, this is not possible

with the On/Off switch 5 actuated.

Right Rotation: For drilling and driving in screws, push the

rotational direction switch 4 left to the stop.

Left Rotation: For loosening or unscrewing screws, push the

rotational direction switch 4 right to the stop.

Setting the torque

With the torque selector switch 6, you can preselect the re-

quired torque in 8 steps. When the torque setting is adjusted

correctly, the insert tool is stopped as soon as the screw is

driven flush into the material or when the set torque is

reached. In the “ ” position, the safety clutch is deactivat-

ed; e.g., for drilling.

In left rotation the safety clutch is deactivated.

Switching On and Off

To start the machine, press the On/Off switch 5 and keep it

pressed.

To switch off the machine, release the On/Off switch 5.

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 ad-

justed, depending on how far the On/Off switch 5 is pressed.

Light pressure on the On/Off switch 5 results in a low rotation-

al speed. Further pressure on the switch results in an increase

in speed.

Fully automatic spindle locking (Auto-lock)

When the On/Off switch 5 is not pressed, the drill spindle and

thus the tool holder are 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.

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 of 70 °C is exceeded, the electronic control

switches off the power tool until the temperature is in the op-

timum temperature range again.

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.

Angle Selection of Drill Head (see figure D)

The drill head can be locked in 5 different angle positions.

Push the release button 7 and swivel the tool head to the re-

quired position. Then, let go of the release button 7 again.

 Before starting operation, check if the drill head is

locked in the respective angle position. Danger of injury.

Working Advice

 Apply the power tool to the screw only when it is

switched off. Rotating tool inserts can slip off.

Utility Clip

The swivelling utility clip 8 can be used to hang the power tool

onto a hook. In this manner, both hands are free and the pow-

er tool is ready to hand.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the power tool, remove the battery.

 For safe and proper working, always keep the machine

and ventilation slots clean.

thorised after-sales service agent for Bosch power tools.

If the machine should fail despite the care taken in manufac-

clude the 10-digit article number given on the type plate of

the machine.
