Tool Change - stayer ROCKY MHL14K Manual De Instrucciones

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.
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.

TOOL CHANGE

The SDS-PLUS tool holder allows for simple and
SDS
convenient changing of drilling tools without the
PLUS
use 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.
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.
CLEANING
When the battery is no longer operative, please refer
to an authorised after-sales service agent for STAYER
power tools.
