6.3 Fitting and adjusting the depth stop
(Fig. 4-5/Item 2)
Undo the thumb screw (a) on the additional
handle (8) and insert the depth stop (2) in the
hole of the additional handle.
Set the depth stop and retighten the thumb
screw.
Now drill the hole until the depth stop touches the
workpiece.
6.4 Fitting the drill bit (Fig. 6-7)
Always pull the power plug before making
adjustments to the equipment.
Release the depth stop as described in 6.3 and
push it towards the additional handle. This
provides free access to the chuck (1).
This hammer drill is equipped with a spindle lock
(9) and a quick-change drill chuck.
Press the spindle lock (9) and turn the drill chuck
(1) until it engages (see Fig. 6). Keeping the
spindle lock (9) pressed, turn the firmly closed
drill chuck (1) so that it opens (see Fig. 7). The
drill chuck opening must be large enough to take
the drill bit.
Select a suitable drill bit. Push the drill bit as far
as possible into the chuck opening.
Keeping the spindle lock (9) pressed, turn the drill
chuck (1) so that it closes. Check that the drill bit
is secure in the chuck (1).
Check at regular intervals that the drill bit or tool is
secure (pull the mains plug).
When the quick-change drill chuck (1) is open as
far as it will go (maximum drill bit opening) and
secure, press the spindle lock (9) and turn the
drill chuck (1) clockwise (viewed from the front)
until you hear a grating noise. Keeping the
spindle lock (9) pressed, turn the drill chuck (1)
approx. 5 mm in the opposite direction until you
hear a clicking noise. Then turn the drill chuck (1)
clockwise again to the desired position. This
function will prevent damage to the drill chuck.
ƽ Important.
Do not press the spindle lock (9) while the drill is in
use.
7. Operation
Hold the tool by the insulated handles when
carrying out work during which the plug-in tool
could strike concealed power cables or its own
mains lead. Contact with a live cable will also make
the metal parts of the tool live and will cause an
electric shock.
7.1 ON/OFF switch (Fig. 8/Item 5)
First fit a suitable drill bit into the tool (see 6.4).
Connect the mains plug to a suitable socket.
Position the drill in the position you wish to drill.
To switch on:
Press the ON/OFF switch (5)
Continuous operation:
Secure the ON/OFF switch (5) with the locking button
(4).
To switch off:
Press the ON/OFF switch (5) briefly.
7.2 Adjusting the speed (Fig. 8/Item 5)
You can infinitely vary the speed whilst using the
tool.
Select the speed by applying a greater or lesser
pressure to the ON/OFF switch (5).
Select the correct speed: The most suitable
speed depends on the workpiece, the type of use
and the drill bit used.
Low pressure on the ON/OFF switch (5): Lower
speed (suitable for: soft materials)
Greater pressure on the ON/OFF switch (5):
Higher speed (suitable for hard materials)
Tip: Start drilling holes at low speed. Then increase
the speed in stages.
Benefits:
The drill bit is easier to control when starting the
hole and will not slide away.
You avoid drilling messy holes (for example in
tiles).
7.3 Preselecting the speed (Fig. 8/Item 6)
The speed controller (6) enables you to define the
maximum speed. The ON/OFF switch (5) can
only be pressed to the defined maximum speed
setting.
Set the speed using the setting ring (6) on the
ON/OFF switch (5).
Do not attempt to make this setting whilst the drill
is in use.
