5. Before starting the equipment
Before you connect the equipment to the mains
supply make sure that the data on the rating plate
are identical to the mains data.
Always pull the power plug before making
adjustments to the equipment.
Check the drilling point for concealed electrical
cables, gas and water pipes using a cable/pipe
detector.
5.1 Additional handle (Fig. 2 – Item 6)
For safety reasons you must only use the
hammer drill with the additional handle.
The additional handle (6) enables you to achieve
better stability whilst using the hammer drill. The
machine must not be used without the additional
handle (6) for safety reasons.
The additional handle (6) 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 (6) into the most
comfortable working position for you. Now turn the
additional handle in the opposite direction again until
the additional handle is secure.
5.2 Fitting and adjusting the depth stop
(Fig. 3/Item 7)
The depth stop (7) is held in place by the additional
handle (6) by clamping. The clamp can be released
and tightened by turning the handle.
Release the clamp and fit the depth stop (7) in
the recess provided for it in the additional handle.
Set the depth stop (7) 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 (6) until
it is secure.
Now drill the hole until the depth stop (7) touches
the workpiece.
5.3. Tool insertion (Fig. 4)
Clean the tool before insertion and apply a thin
coating of drill bit grease to the shaft of the tool.
Pull back and hold the locking sleeve (2).
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.
5.4 Tool removal (Fig. 5)
Pull back and hold the locking sleeve (2) and remove
the tool.
5.5 Dust collection device (Fig. 6)
Slide the dust collection device (a) over the drill bit
before carrying out any hammer drilling vertically
above your head.
6. Starting up
Important.
To prevent all danger, the machine must only be
held using the two handles (6/8).
Otherwise there
may be a risk of suffering an electric shock if you drill
into cables.
6.1 Switching on and off (Fig. 1)
To switch on:
Press the control switch (4).
To switch off:
Release the control switch (4).
6.2 Hammer stop facility (Fig. 7)
The hammer drill has a hammer stop facility for
gentle initial drilling.
Turn the rotary switch for the hammer stop
facility (5) 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).
6.3 Rotation stop facility (Fig. 8 / 9)
The rotation function of the hammer drill can be
switched off for chiseling jobs.
To do this, press the button (C) on the rotary
switch (3) whilst at the same time turning the
rotary switch (3) into position A (see Fig. 8).
To switch on the rotation facility again, press
button (C) on the rotary switch (3) whilst at the
same time turning the rotary switch (3) into
position B (see Fig. 9).
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.
Excessive pressure will exert an unnecessary force
on the motor. Check the drill bits at regular intervals.
Sharpen or replace blunt drill bits.
