Reversal of the direction of rotation
The direction of rotation switch (4) is used to reverse the direction of rotation of the
machine; however, this is not possible if the on / off switch (6) is actuated.
Right rotation
Turn the drilling / hammer drilling selector (4) on both
sides up to the stop in position
Rotation to the left
Turn the drilling / hammer drilling selector (4) on both
sides as far as the stop in position
Adjust the direction of rotation for hammer drilling, drilling and chiselling always to the
right.
On and off
•
To turn on the machine, press the on / off switch (6).
• To lock the on / off switch, hold it down and also press the lock button (5).
•
To turn off the machine, release the on / off switch (6).
Note: When the on / off switch (6) is locked, press it first and then release it.
Impact rate / speed setting
The speed / impact rate of the switched on tool can be adjusted variably, depending on
how much the on / off switch (6) is pressed.
•
A slight pressure on the on / off switch (6) results in a low speed / impact rate.
• Higher pressure on the switch increases the speed / impact rate.
Safety clutch
If the tool insert snags or binds, the drill spindle drive is interrupted. Due to the forces
that occur, always hold the power tool firmly with both hands and maintain a safe posture.
If the power tool sticks, turn the machine off and loosen the tool insert. When starting the
machine with the drilling tool stuck, high reaction torques can occur.
Job tips
Before carrying out any work on the machine itself, unplug the plug
Changing the chiseling position (Vario-Lock)
The chisel can be locked in 36 positions. In this way, the optimal working position can be
established for each application.
•
Insert the chisel into the chuck.
• Turn the mode selector (8) to the “Vario-Lock” position.
•
Rotate the chuck to the desired chiseling position.
• Turn the mode selector (8) to the "chisel" position. The tool holder is now locked.
•
For chiseling, set the direction of rotation to clockwise rotation.
