Set the depth stop 2 to the same level as the drill bit.
Pull the depth stop back by the required drilling depth.
Turn the handle on the additional handle 7 until it is secure.
Now drill the hole until the depth stop 2 touches the
workpiece.
Fitting the drill bit (Fig. 5-6)
Always pull the power plug before making adjustments to
the equipment.
The quick-change drill chuck 1 is equipped with a locking
fastener:
To lock = press the sleeve (a) forwards
To unlock = press the sleeve (a) backwards
release depth stop as described in the previous section
and push it towards the additional handle. This provides
free access to the chuck 1.
This hammer drill is fitted with a keyless chuck 1.
Open the chuck 1. The drill bit opening must be large
enough to fit the drill bit into.
Select a suitable drill bit. Push the drill bit as far as possible
into the chuck opening.
Close the chuck 1. 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).
Electrical connection
Observe correct mains voltage! The voltage of the
power source must agree with the voltage specified
on the nameplate of the machine. Power tools marked
with 230 V can also be operated with 220 V.
If the power cable for this equipment is damaged, it must
be replaced by the manufacturer or its aftersales service or
similarly trained personnel to avoid danger.

Press the ON/OFF switch 5 briefly.
Adjusting the speed (Fig. 7/Item 5)
You can infinitely vary the speed whilst using thetool.
Select the speed by applying a greater or lesserpressure to
the ON/OFF switch 5.
Select the correct speed: The most suitablespeed depends
on the workpiece, the type of useand the drill bit used.
Low pressure on the ON/OFF switch 5: Lower speed
(suitable for: small screws and soft materials) Greater
pressure on the ON/OFF switch 5: Higher speed (suitable
for large/long screws and 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).
Preselecting the speed (Fig. 7/Item 6)
The speed setting ring 8 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 8 on the ON/OFF
switch 5.
Do not attempt to make this setting whilst the drill is in use.
Clockwise/Counter-clockwise switch (Fig. 7/Item 6)
Change switch position only when the drill is at a standstill!
Switch the direction of the hammer drill using the clockwise/
counter-clockwise switch (6):
Direction ---------------------------------------------Switch position
Clockwise (forwards and drill) -----------------------------------R
Counter-clockwise (reverse) -------------------------------------L
