g)
If devices are provided for the connection of dust extraction
and collection facilities, ensure these are connected and prop-
erly used.
Use of these devices can reduce dust-related hazards.
h)
Wear ear protectors.
Exposure to noise can cause hearing loss.
i)
Usse auxiliary handles supplied with the tool.
Loss of control can
cause personal injury.
4) Power tool use and care
a)
Do not force the power tool. Use the correct power tool for your
application.
The correct power tool will do the job better and safer at
the rate for which it was designed.
b)
Do not use the power tool if the switch does not turn it on and
off.
Any power tool that cannot be controlled with the switch is dan-
gerous and must be repaired.
c)
Disconnect the plug from the power sourc e and/or the battery
pack from the power tool before making any adjustments,
changing accessories, or storing power tools.
Such preventive
safety measures reduce the risk of starting the power tool acciden-
tally.
d)
Store idle power tools out of the reach of children and do not
allow persons unfamiliar with the power tool or these instruc-
tions to operate the power tool.
Power tools are dangerous in the
hands of untrained users.
e)
Maintain power tools . Check for misalignment or binding of
moving parts , breakage of parts and any other condition that
may affect the power tools operation. If damaged, have the
power tool repaired before use.
Many accidents are caused by
poorly maintained power tools.
f)
Keep cutting tools sharp and clean.
Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier to
control.
g)
Use the power tool, accessories and tool bits etc. in accord-
ance with these instructions and in the manner intended for
the particular type of power tool, taking into account the
working conditions and the work to be performed.
Use of the
power tool for operations different from those intended could result in
a hazardous situation.
5) Service
a)
Have your power tool serviced by a qualified repair person
using only identical replacement parts.
This will ensure that the
safety of the power tool is maintained.
Supplementary handle assembly
Before any interference to the tool, disconnect the supply cable first. Use
the hammer only with supplementary handle (10). Mount the handle to
the fastening neck and secure with revolving grip.
Putting into operation
Connect only to a single-phase alternating current power network with
voltage marked on the nameplate. It is possible to connect the tool even
to outlets without a protective contact, as this is a class II appliance.
Check, if the plug type corresponds with type of the outlet.
Switching on/off
The hammer is equipped by the information LED (7) indicating connec-
tion to the power supply system. As soon as the plug is inserted into
the socket, the diode goes on green. The switch can be fixed in the ON
position by the lock button (5).
The hammer is switched on by depressing the switch (5). The device
goes off as soon as you release the switch.
Notice: For your safety the switch cannot be secured/locked in the
ON position.
It is prohibited to bypass (get round) this safety mechanism.
Function switch (6)
The change-over switch of functions (6) has three basic positions:
= impact drilling,
= speed switching off; chipping,
0
= position setting for chipping.
Change the functions in the rest position only. Simply swivel the switch
to the requested position.
The hammer drill gearbox will be switched to the selected position after
depressing the switch (5) and/or as soon as the hammer drill is started.
Impact drilling
For impact drilling swivel the function switch (6) onto the symbol
.
Use only and exclusively the recommended drills with the SDS–max.
shank for impact drilling.
You cannot use the impact drills with the cylindrical shank specified for
common chucks (quick-acting chucks or chucks with handle) for this
pneumatic hammer drill.
Chipping
For chipping swivel the function switch (6) onto the symbol
.
Use only and exclusively the recommended chisels with the SDS–max.
shank for chipping.
Setting chisel position for chipping
Move the function switch (6) to position
0
. By hand swiveling, you can
set the chisel into one of 16 basic working positions.
Then switch the function switch (6) back to position
. The chisel
will be locked automatically as soon as the radial pressure will be ap-
plied, when chipping.
Inserting and removing bits
Drilling and chiseling bits are inserted to and removed from the chuck
head (1) without a key.
Inserting bits
Before any interference to the tool, disconnect the supply cable first.
Clean the shank of the bit and grease it slightly.
When setting the tool into the clamping head, pull the fixing sleeve (3)
towards the body of the device and swivel the tool slowly until it is is
locked (seated firmly).
Be careful not to damage the cover protecting the chuck head
against dust penetration (2).
Replace damaged dust cover immediately with a new one!
Removing bits
Push the locking sleeve (3) down towards the body of the hammer and
remove the bit.
Rotation regulation
You can continuously change rotations with the switch (5). Push the
switch slightly and the hammer will start rotating slowly. The stroger
you push at the switch, the faster the rotation.
User’s protection
Safety clutch
The device is equipped by the dynamic safety clutch which starts to slip
for a short-time immediately after the drilling tool is jammed. It protects
the user from injury due to the return stroke.
Antivibration extras for the device
The device is equipped by antivibration components, e.g. the main
sprung handle (9) and by the soft and flexible grip part of the exten-
sion handle, damping the vibrations transferred from the device to the
operator effectively.
Tips for practice
Do not drill on the places where hidden el. distribution lines, gas or wa-
ter pipes could be laid. At first check the place where you intend to drill,
using for instance the metal detector.
Use only and exclusively the recommended drills with the SDS–max.
shank for impact drilling.
Adapt speed to the material you drill into and to the used drill diam-
eter.
Use protective goggles and ear protectors and work with the extension
handle (10).
Do not apply a very high force on the hammer drill during vertical drill-
ing. Its performance will not be increased anyhow.
