OPERATION INSTRUCTION
5
Rotating the Auxiliary Handle, the auxiliary handle
11 can be set to any position for a secure and
low-fatigue working posture.
Turn the bottom part of the auxiliary handle 11 in
counterclockwise direction and swivel the
auxiliary handle 11 to the desired position. Then
retighten the bottom part of the auxiliary handle
11 by turning in clockwise direction.
Pay attention that the clamping band of the
auxiliary handle is positioned in the groove on the
housing as intended for.
b) Changing the Tool
The dust protection cap 3 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care that
the dust protection cap 3 is not damaged.
A damaged dust protection cap should be
changed immediately. We recommend having
carried out by an after-sales service.
Inserting SDS-plus Drilling Tools, the SDS drill
chuck allows for simple and convenient changing
of drilling tools without the use of additional 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.
As a requirement of the system, the SDS drilling
tool can move freely. This causes a certain radial
run-out at no-load, which has no effect on the
accuracy of the drill hole, as the drill bit centre
itself upon drilling.
Removing SDS Drilling Tools, push back the
locking sleeve 4 and remove the tool.
4) Operation
1. Starting Operation
Observe correct mains voltage! The Voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Setting the Operating mode, with the selector
switch for drilling/ hammer drilling 9, the operating
mode of the machine is selected. To change the
operating mode, press the release button 8 and
turn the drilling/ hammer drilling selector switch 9
to the desired position until can be heard to latch.
Note:
only change the mode of operation while
disconnected from the machine! Otherwise you
may damage the machine.
Position for hammer drilling in concrete (fig.12).
Position for drilling without impact in wood, metal,
ceramic and plastic as well as for screw driving
and thread cutting. (fig.14).
Reversing the rotational direction, the rotational
direction switch 5 is used to reverse the rotational
direction of the machine. However, this is not
possible with the On/Off switch 7 actuated.
Right rotation: turn the selector switch for
drilling/hammer drilling 5 on both sides to the stop
in the position.
Left rotation: turn the selector switch for
drilling/hammer drilling 5 on both sides to the stop
in the position.
Set the direction of rotation for hammer drilling,
drilling and chiseling always to right rotation.
Switching On and Off, to start the machine, press
the On/Off switch, keep it pressed and additiona-
lly push the lock-on button 6. To switch off the
machine, release the On/Off switch 7.
When the On/Off switch 7 is locked, press it first
and then release it.
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
7/10 is pressed.
Light pressure on the On/Off switch 7/10 results
in low speed/impact rate. Further pressure on the
switch increases the speed/ impact rate.
