WARNING
The vibration and noise emission level given in this information sheet has been measured in accordance with a standardized test given in EN
62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration and noise emission level represents the main applications of the tool. However if the tool is used for diff erent
applications, with diff erent accessories or poorly maintained, the vibration and noise emission may diff er. This may signifi cantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration and noise should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may signifi cantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the eff ects of vibration and/or noise such as: maintain the tool and the
accessories, keep the hands warm, organization of work patterns.
WARNING!
Read all safety warnings, instructions,
illustrations and specifi cations provided with this power tool.
Failure to follow all instructions listed below may result in electric
shock, fi re and/or serious injury.
Save all warnings and instructions for future reference.
HAMMER SAFETY WARNINGS
Safety instructions for all operations
Wear ear protectors. Exposure to noise can cause hearing loss.
Use auxiliary handles supplied with the tool. Loss of control can
cause personal injury.
Hold the power tool by insulated gripping surfaces only,
when performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the power
tool "live" and could give the operator an electric shock.
Safety instructions when using long drill bits with rotary
hammer
Always start drilling at low speed and with the bit tip in contact
with the workpiece. At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting the workpiece, resulting
the personal injury.
Apply pressure only in direct line with the bit and do not apply
excessive pressure. Bits can bend causing breakage or loss of
control, resulting in personal injury.

ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes,
hard hat or hearing protection used for appropriate conditions will
reduce personal injuries.
The dust produced when using this tool may be harmful to health.
Do not inhale the dust. Wear a suitable dust protection mask.
Do not machine any materials that present a danger to health (e.g.
asbestos).
Switch the device off immediately if the insertion tool stalls! Do not
switch the device on again while the insertion tool is stalled, as
doing so could trigger a sudden recoil with a high reactive force.
Determine why the insertion tool stalled and rectify this, paying heed
to the safety instructions.
The possible causes may be:
• it is tilted in the workpiece to be machined
• it has pierced through the material to be machined
• the power tool is overloaded
Do not reach into the machine while it is running.
The insertion tool is sharp-edged and can become hot during use.
WARNING! Danger of cuts and burns
- when handling the insertion tools
- when setting the device down.
Wear protective gloves when handling insertion tools.
Chips and splinters must not be removed while the machine is
running.
ENGLISH
Keep mains lead clear from working range of the machine. Always
lead the cable away behind you.
When working in walls ceiling, or fl oor, take care to avoid electric
cables and gas or waterpipes.
Clamp your workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
Always disconnect the plug from the socket before carrying out any
-1
work on the machine.

When working with large drill diameters, the auxiliary handle must
be fastened in a right angle with the main handle (see illustrations,
-1
section "Twisting the handle").
SPECIFIED CONDITIONS OF USE
KH7E: This rotary hammer can be used universally for hammer-
drilling, chiselling, and drilling.
MH7E: The percussion hammer can be used for chiselling in stone
and concrete.
Do not use this product in any other way as stated for normal use.
RESIDUAL RISK
Even when the product is used as prescribed, it is still impossible
to completely eliminate certain residual risk factors. The following
hazards may arise in use and the operator should pay special
/ 1,5m/s

attention to avoid the following:
2
/ 1,5 m/s
2
• Injury caused by vibration.
Hold the product by designated handles and restrict working time
and exposure.
• Exposure to noise can cause hearing injury.
Wear ear protection and limit exposure.
• Injury due to fl ying debris
Wear eye protection, heavy long trousers and substancial
footwear at all times.
• Inhalation of toxic dusts.
MAINS CONNECTION
Appliances used at many diff erent locations including wet room and
open air must be connected via a residual current device (FI, RCD,
PRCD) of 30mA or less.
Connect only to single-phase AC current and only to the system
voltage indicated on the rating plate. It is also possible to connect
to sockets without an earthing contact as the design conforms to
safety class II.
Make sure the machine is switched off before plugging in.
This is a device for professional use which may slightly exceed the
guide values for current harmonics when it is connected to the public
low voltage mains supply. You should therefore contact your energy
supply company before you connect the device to the public low
voltage mains supply.
WORKING INSTRUCTIONS
Do not force too much when drilling or hammering. Let the rotary
hammer do the work for you.
WORK WHEN IT'S COLD
If the tool is stored for a long period of time or at cold temperatures,
the lubrication may become stiff and the tool may not working initially
or the working may be weak. If this happens:
1. Insert a bit or chisel into the tool.
2. Run the tool against a scrap piece of concrete.
3. Pull and release the trigger every few seconds.
After 15 seconds to 2 minutes, the tool will start hammering
normally. The colder the tool is, the longer it will take to warm up.
CLEANING
The ventilation slots of the machine must be kept clear at all times.
MAINTENANCE
Important note! If the carbon brushes are worn, in addition to
exchanging the brushes the tool should be sent to after-sales
service. This will ensure long service life and top performance.
