Charge-control Indicator
The battery
10
is fitted with a charge-control indica-
tor
12
. It indicates the charge of the battery at any
given time during the working process.
By pressing the button
13
, the battery charge can
also be checked when the battery has been
removed, or when the machine is at a standstill
(machine must be switched off for at least 1 minute).
After approx. 4 seconds the battery charge display
automatically turns off.
When the first display element begins to flash (0 –
10 %) the battery is almost empty and must be
recharged.
Auxiliary Handle/Depth Stop
(see figure
)
❏
Operate the machine only with the auxiliary
handle 11.
Loosen the handle by turning to the left. Rotate the
auxiliary handle
11
and adapt to the working posi-
tion. Make sure that the clamping band
14
of the
auxiliary handle remains in the groove.
Afterwards tighten the handle again by turning in
clockwise direction.
The drilling depth can be set with the depth stop
3
.
For this, press the button for the depth-stop adjust-
ment
4
, adjust the required drilling depth
X
and
release the button again.
The ribbing on depth stop
3
must point upwards.
Changing the Tool
❏
Before any work on the machine itself, remove
the battery.
With the SDS-plus tool holder, simpler and easier
tool changing is possible without additional aids.
Grease the shank end of the tool regularly.
The dust protection cap
1
largely prevents the entry
of drilling dust during operation. When inserting the
tool, take care that the dust protection cap
1
is not
damaged.
A damaged dust protection cap should be changed
immediately. We recommend having this carried
out by an after-sales service.
☞
As a requirement of the system, the SDS-plus
tool must rotate freely. At no-load speed, this
leads to a certain amount of radial run-out.
This does not affect the accuracy of the drill
hole, as the bit is automatically centred during
drilling.
Inserting (see figure
)
Clean and grease the shank end of the tool.
Insert the tool in a twisting manner into the tool
holder until it locks. Check if it has locked by pulling
the tool.
Removing (see figure
)
Push back the locking sleeve
2
of the tool holder and
remove the tool.
Starting Operation
Inserting the Battery
Set the rotational direction switch
7
to the centre
position (locked off). Slide the charged battery
10
into the handle until it can be felt to latch.
Switching On and Off
To
start
the machine, press the On/Off switch
8
and
keep it depressed.
The machine runs with variable speed between 0
and maximum, depending on the pressure applied
to the On/Off switch
8
. Light pressure on the On/
Off switch
8
results in low rotational speed, thus
allowing smooth, controlled starts. Further pressure
on the switch results in an increase in speed.
To
switch off
the machine, release the On/Off
switch
8
.
Do not strain the machine so heavily that it comes to
a standstill.
❏
The machine is not suitable for stationary opera-
tion, e. g., in a drill stand.
Reversing the Rotational Direction
Operate the rotational direction switch 7
only at a standstill.
The rotational direction switch
7
is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch
8
pressed.
Right Rotation
Press the rotational direction
switch through to the right stop
(normal operation).
Left Rotation
Turn the rotational direction
switch through to the left stop.
