To change the operating mode, turn the selector switch for
"drilling/hammer drilling" 4 to the requested position.
Position for hammer drilling in concrete or stone
Position for drilling without impact in wood,
metal, ceramic and plastic as well as for
screwdriving
Reversing the Rotational Direction (see figure C)
Actuate the rotational direction switch 8 only when the
machine is at a standstill.
The rotational direction switch 8 is used to reverse 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
pressed.
To switch off the machine, release the On/Off switch 9.
For low temperatures, the power tool reaches the full
hammer/impact capacity only after a certain time.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power 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.
4.2 General instructions for use
For hammer drilling, SDS-PLUS tools are required.
For drilling without impact in wood, metal, ceramic and
plastic, a suitable SDS-PLUS tool or an application tool with
hexagon shank can be used.
For screwdriving, use only screwdriver bits with ball catch
12. Other screwdriver bits 11 can be inserted via a universal
bit holder with ball catch 10.
A selection of suitable application tools can be found in the
Accessories Overview at the end of these instructions.
Apply the power tool to the screw/nut only when
it is switched off. Rotating tool inserts can slip off.

4.3 Tool change
The SDS-PLUS tool holder allows for simple and
SDS
convenient changing of drilling tools without the use
PLUS
of additional tools.
Due to their working principle, SDS-PLUS drilling tools
move freely. This results in radial runout at no-load.
However, this has no effect on the accuracy of the drill hole,
as the drill bit centres itself during drilling.
The SDS-PLUS tool holder can also accommodate different
drill-bit types with hexagon shank. For more information,
see the accessories page at the end of these operating
instructions.
The dust protection cap 2 largely prevents the entry of
drilling dust into the tool holder during operation. When
inserting the tool, take care that the dust protection cap 2 is
not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
Inserting SDS-PLUS Drilling Tools
Clean and lightly grease the shank end of the tool.
Insert the tool in a twisting manner into the tool holder until it
latches itself.
Check the latching by pulling the tool.
Removing SDS-PLUS Drilling Tools
Push back the locking sleeve 3 and remove the tool.
5. Maintenance and service instructions
For safe and proper working, always keep the
machine and ventilation slots clean.
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as during
transport and storage, set the rotational direction
switch to the centre position. Unintentional actuation of
the On/Off switch can lead to injuries.
A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
5.1 Cleaning
When the battery is no longer operative, please refer to an
authorised after-sales service agent for STAYER power
tools.
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should be
carried out by an after-sales service centre for STAYER
power tools.
In all correspondence and spare parts order, please always
include the 10-digit article number given on the type plate of
the machine.
