4.2.- Working Advice

Changing the Chiselling Position
The chisel SDS can be locked in different positions.
In this manner, the optimum working position can be
set for each application.
Insert the chisel into the tool holder.
Turn the mode selector switch 8
Turn the tool holder to the desired chiselling position.
Turn the mode selector switch 8 to the "chiseling"
position. The tool holder is now locked.
For chiselling, set the rotation direction to right rota-
tion.
Switching On/Off: A
To start the machine, press the On/Off switch 6
and keep it depressed.
To switch off the machine, release the On/Off
switch 6.
Switching On/Off: B
To start the machine, press the On/Off switch 6/7
at the top ( I ) until it locks.
To switch off the machine, press the On/Off
switch 6/7 at the bottom (O) and release it.
For low temperatures, the power tool reaches
the full hammer/impact capacity only after a certain
time.
Setting the Speed/Impact Rate
The electronic control 10 enables stepless
speed and impact preselection in accordance
with the material to be worked.

The maximum hammering capacity is achieved
when the thumbwheel 10 is set to position "6".
(HD50K) For lower speed settings, the hammering
capacity is lower due to technical reasons.

4.3. - Starting Operation
f Observe correct mains voltage! The voltage
of the power source must agree with the vol-
tage specified on the nameplate of the ma-
chine. Power tools marked with 230V can
also be operated with 220V.
Switching On and Off
To start the machine, push the On/Off switch 6/7
to the "I" position.
To switch off the machine, push the On/Off switch
6/7 to the "O" position.
For low temperatures, the machine reaches the
full impact rate only af
This start-up time can be shortened by striking
the chisel in the machine against the floor one
time.
4.4.- Operating Instructions
While working, hold the power tool with both hands
by the handle 1.
For the highest possible impact damping, work
only with moderate pressure.

5.- Maintenance and Service

5.1.- Maintenance and Cleaning

f Before any work on the machine itself, pull
the mains plug.
f For safe and proper working, always keep
the machine and ventilation slots clean.
