GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings
and all instructions. Failure to fol-
low the warnings and instructions
may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions
for future reference.
The term “power tool” in the warnings refers to
your mains-operated (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. Power 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. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased
risk of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
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 and moving parts. Damaged or entan-
gled 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 loca-
tion is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD
reduces the risk of electric shock.
g) Make sure you have a proper connection of
the tool at a socket outlet.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power
tool. Do not use a power tool while you are
tired or under the influence of medication.
A moment of inattention while operating
power tools may result in serious personal
injury.
b) 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.
c) Prevent unintentional starting. Ensure the
switch is in the off-position before connect-
ing 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.
d) 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.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better con-
trol of the power tool in unexpected situa-
tions.
f ) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jew-
ellery or long hair can be caught in moving
parts.
g) 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.
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-

KARAT®180 US
OPERATING MANUAL KARAT® 180 5
gerous and must be repaired.
c) 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 measures reduce the risk of
starting the power tool accidentally.
d) 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 dan-
gerous in the hands of untrained users.
e) Maintain power tools. Check for misalign-
ment or binding of moving parts, breakage of
parts and any other condition that may affect
the power tool’s 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 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.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replace-
ment parts. This will ensure that the safety of
the power tool is maintained.
b) For power tools with type X attachment,
where a specially preparde cord is needed
to replace the cord: if the supply cord of this
power tool is damaged, it must be replaced
by a specially preparded cord available
through a qualified service facilty.
FOR YOUR SAFETY
Please read and comply with these
instructions prior to the initial
operation of your device.
Retain these instruction manual for
future reference or for subsequent
possessors.
WARNING: Prior to the first start-
up, it is definitely necessary to read
the Safety instructions!
In case you do not adhere to this instruction
manual and the safety instructions, this may result
in damages on the device and cause dangerous
situations for the operator and other people. In
case of transport damage inform vendor imme-
diately.
