Check the drilling point for concealed electrical cables,
gas and water pipes using a cable/pipe detector.
Additional handle
For safety reasons you must only use the hammer drill
with the additional handle. The additional handle enables
you to achieve better stability whilst using the hammer
drill. The machine must not be used without the additional
handle for safety reasons.
The additional handle is secured to the hammer drill by
a clamp. Turning the handle anti-clockwise (looking from
the handle) will release the clamp.
Turning the handle clockwise will tighten the clamp.
First release the additional handle clamp. You can then
swing the additional handle into the most comfortable
working position for you. Now turn the additional handle
in the opposite direction again until the additional handle
is secure.
Depth stop
The depth stop is held in place with the locking screw on
the additional handle by means of a clamp.
▶ Undo the locking screw and fit the depth stop.
▶ Set the depth stop to the same level as the drill bit.
▶ Pull the depth stop back by the required drilling depth.
▶ Retighten the locking screw.
▶ Now drill the hole until the depth stop touches the
workpiece.
Tool insertion
▶ Clean the tool before insertion and apply a thin coat -
ing of drill bit grease to the shaft of the tool.
▶ Pull back and hold the locking sleeve.
▶ Insert the dust-free tool into the tool mounting as far
as it will go whilst turning it. The tool will lock itself.
▶ Check that it is properly secure by pulling the tool.
Tool removal
Pull back and hold the locking sleeve and remove the tool.
Dust collection device
Slide the dust collection device over the drill bit before
carrying out any hammer drilling vertically above your
head.

To prevent all danger, the machine must only be
held using the two handles.
Otherwise there may be a risk of suffering an electric
shock if you drill into cables.

Hammer stop facility
The hammer drill has a hammer stop facility for gentle
initial drilling.
▶ Turn the rotary switch for the hammer stop facility to
position (B) to switch off the hammer facility.
▶ To switch on the hammer facility again the rotary
switch for the hammer stop facility (5) must be turned
back to position (A).
Rotation stop facility
▶ For hammer drilling, press the button (E) on the ro -
tary switch (3) and simultaneously turn the rotary
switch (3) to position A.
▶ For chiseling, press the button (E) on the rotary
switch (3) and simultaneously turn the rotary switch
(3) to position B. In switch position A the chisel is not
locked.

switch (3) and simultaneously turn the rotary switch
(3) to position C. The chisel is locked in position C.
Important.
Please note that it is not possible to operate the hammer
drill with the hammer stop and rotation stop facilities
both active at the same time.
Important.
Only low pressure is required for hammer drilling. Ex -
cessive pressure will exert an unnecessary force on the
motor. Check the drill bits at regular intervals. Sharpen
or replace blunt drill bits.
