Changing The Tool; Initial Operation - stayer BH12 Manual De Instrucciones

To remove the battery 6, press the unlocking buttons
7 and pull out the battery downwards. Do not
exert any force.
The battery is equipped with an NTC temperature
control which allows charging only within a tempera-
ture range of between 0 °C and 45 °C. A long
battery service life is achieved in this manner.
A significantly reduced working period after
charging indicates that the batteries are used and
must be replaced.
Observe the notes on environmental protection.

Changing the Tool

Open the drill chuck 2 by turning until the tool can
be inserted. Insert the tool.
Firmly tighten the sleeve of the keyless chuck 2
by hand. This automatically locks the chuck.
Rotate the sleeve in the reverse direction to remove
the tool.

Initial Operation

Inserting the Battery
Set the rotational direction switch 4 to the centre
position = lock-off and allow the charged battery
6 to engage into the handle.
Switching On and Off
To start the machine, press the On/Off switch 3
and keep it depressed.
The machine runs with variable
speed between 0 and maximum,
depending on the pressure applied
to the On/Off switch 3. Light pressure
results in a low rotational
speed thus allowing smooth, con-
trolled starts. Do not strain the ma-
chine so heavily that it comes to a
standstill.
To switch off the machine, release the On/Off
switch 3.

switch 4 only at a standstill.
Right Rotation (a )
Turn the rotational direction switch through to the
left stop (normal operation: drilling, screwdriving,
etc.).
Left Rotation (b )
Press the rotational direction switch through to
the right stop (for loosening and unscrewing
screws and nuts).
Setting the Torque
With the correct setting, the clutch disengages as
soon as the screw is driven flush into the material
or the set torque is reached. Select a higher setting
when driving out screws, or set to the "Drilling"
symbol.

Low setting, e. g., small screws, soft
materials.
