Operation

Starting Operation

Inserting the Battery

f Use only original Bosch O-pack batteries

with the voltage given on the type plate of

your machine. The use of other batteries can

lead to injuries and danger of fire.

Set the rotational direction switch 8 to the cen-

tre position in order to avoid unintentional start-

ing. Insert the charged battery 11 into the han-

dle so that it can be felt to engage and faces

flush against the handle.

Setting the Operating Mode

f Actuate the selector switch for drill-

ing/hammer drilling 7 only when the power

tool is at a standstill.

Hammer drilling

Set the selector switch 7 to the

“Hammer drilling” symbols.

Drilling

Set the selector switch 7 to the

“Drilling” symbol.

Reversing the Rotational Direction

f Actuate the rotational direction switch 8

only when the machine is at a standstill.

The rotational direction switch 8 is used to re-

verse the rotational direction of the machine.

However, this is not possible with the On/Off

switch 9 actuated.

Right Rotation: For drilling and driving in

screws, push the rotational direction switch 8

left to the stop.

Left Rotation: For loosening and unscrewing

screws and nuts, press the rotational direction

switch 8 through to the right stop.

Switching On and Off

To start the machine, press the On/Off switch 9

and keep it depressed.

To switch off the machine, release the On/Off

switch 9.

For low temperatures, the machine reaches the

full hammer/impact capacity only after a certain

time.

This start-up time can be shortened by striking

the inserted tool insert against the floor one

time.

Setting the Speed/Impact Rate

The speed/impact rate of the switched on pow-

er tool can be variably adjusted, depending on

how far the On/Off switch 9 is pressed.

Light pressure on the On/Off switch 9 results in

low speed/impact rate. Further pressure on the

switch increases the speed/impact rate.
