1 Specified Conditions of Use
In conjunction with the appropriate accessories,
this rotary hammer drill is suitable for impact
drilling and chiselling (KHE 2443 only) into
concrete, stone and other such materials, into
brickwork with drill bits, and non-impact drilling
into metal, wood etc. and for driving screws.
The user bears sole responsibility for any damage
caused by inappropriate use.
Generally accepted accident prevention
regulations and the enclosed safety information
must be observed.
2 General Safety Information
WARNING – Reading the operating
instructions will reduce the risk of injury.
For your own protection and for the
protection of your power tool pay attention to all parts of the text that are
marked with this symbol!
General Power Tool Safety Warnings
WARNING
all instructions. Failure to follow the warn-
ings and instructions may result in electric shock,
fire and/or serious injury.
Read all safety warnings and
Save all warnings and
instructions for future reference!
"power tool" in the warnings refers to your mainsoperated (corded) power tool or battery-operated
(cordless) power tool.
1) Work area safety
a)
Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
b)
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.
tools create sparks which may ignite the dust
or fumes.
c)
Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a)
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools.

b)
Avoid body contact with earthed or
grounded surfaces, such as pipes, radiators, ranges and refrigerators.

Do not expose power tools to rain or wet
conditions.
increase the risk of electric shock.
d)
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts.
entangled cords increase the risk of electric
shock.
e)
When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f)
If operating a power tool in a damp location
is unavoidable, use a residual current
device (RCD) protected supply.
RCD reduces the risk of electric shock.

power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication. A moment of
inattention while operating power tools may
result in serious personal injury.
Use personal protective equipment.
Always wear eye protection. Protective
equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal
injuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before
connecting to power source and/or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energising power tools that have the
switch on invites accidents.
Remove any adjusting key or wrench
before turning the power tool on. A wrench
or a key left attached to a rotating part of the
power tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.
clothes, jewellery or long hair can be caught in
moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used.
Use of dust collection can reduce
dust-related hazards.
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.
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
dangerous and must be repaired.
Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjustments,
changing accessories, or storing power
tools.
Such preventive safety mea ures reduce
the risk of starting the power tool accidentally.
Store idle power tools out of the reach
of children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.

poorly maintained power tools.
Keep cutting tools sharp and clean.
f)
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 accordance with these instructions, 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.

Avoid inadvertent starts by always unlocking the
switch when the plug is removed from the mains
socket or in case of a power cut.
Do not touch the rotating tool!
Remove chips and similar material only with the
machine at standstill.
Caution must be exercised when driving screws
into hard materials (driving screws with metric or
imperial threads into steel)! The screw head may
break or a high reverse torque may build up on the
handle.
Pull the plug out of the plug socket before any
adjustments or servicing are performed.
Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory
diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic
such as oak and beech dust especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing
asbestos must only be treated by specialists.
- Where the use of a dust extraction device is
possible it shall be used.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is
recommended.
Follow national requirements for the materials you
want to work with.

A single switch button allows you to switch
between drilling, hammer drilling and chiselling
modes, depending on the features.
• Metabo S-automatic safety clutch:
If the tool jams or catches, the power supply to
the motor is restricted. Due to the strong force
which can arise, always hold the machine with
both hands using the handles provided, stand
securely and concentrate.
• Electronic smooth start-up for precision drilling
• Rotary stop (KHE2443):
Chiselling can be carried out if the rotary motion
is switched off.
• Lockable switch for convenient operation
during continuous chiselling

8Tips and Tricks
Only moderate pressure is required for hammer
drilling and chiselling. Exerting a high force does
not increase performance.
When drilling deep holes, remove the drill bit
periodically from the hole to release the stone
dust.
Drill tiles and other brittle materials without impact.
9 Maintenance
The vent slots of the machine should be cleaned
from time to time.
