3. CHANGING THE TOOL

WARNING: Before any work on the 

power tool (e.g., maintenance, tool change, 

etc.) as well as during transport and 

storage, set the rotational direction switch 

to the center position. 

Unintentional actuation 

of the on/off switch can lead to injuries.

Hold the keyless chuck 3 firmly; turn it anti-

clockwise, until the drilling bit can be inserted.

4. INSERTING THE BATTERY

WARNING: 

Use only lit

hium-

ion batteries 

 with the voltage listed on the na

m

eplate 

of your power tool. Using other batteries can 

lead to injuries and pose a 

fi

re 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 center 

position in order to avoid unintentional starting. 
Align the raised rib on the battery pack with the 

grooves of the drill, and then attach the battery 

pack to the drill, until you hear “click” to indicate 

the battery pack is attached tightenly.

5. DIRECTION-OF ROTATION

The direction-of rotation switch 5 is used to 

reverse the rotational direction of the machine. 

However, this is not available when the on/off 

switch 1 actuated.

Right rotation:

 for drilling and driving in 

screws, push the direction-of-rotation switch 5 

left to the stop.

Left rotation:

 for loosening and unscrewing 

screws and nuts, press the direction-of-rotation 

switch 5 through to the right stop.

6. SETTING THE TORQUE

With the T

orque-adjustment ring 4 the required 

torque setting can be preselected in 17 steps. 

When using the drill for different driving 

applications, increase or decrease the torque in 

order to help prevent damaging scre

w, heads, 

threads, workpiece etc.
The proper setting depends on the job and the 

type of bit, and material you will be using. In 

general, use greater torque for larger screws. 

If the torque is too high, the screws may be 

damaged or broken.

For delicate operations, use a low torque 

setting. For operations such as drilling into 

hardwood, use a higher torque setting.
