IMPORTANT!
■Keep this instruction manual in a safe
place for future reference.
■Read the instructions carefully. Be familiar
with the controls and the proper use of the
equipment.
■Never use the machine while people,
especially children, or pets are nearby.
Keep in mind that the operator or user
is responsible for accidents or hazards
occurring to other people or their property.
■This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision or
instruction concerning use of the appliance
by a person responsible for their safety.
■Children should be supervised to ensure
that they do not play with the appliance.
WORK AREA SAFETY
■Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
■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.
■Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
ELECTRICAL SAFETY
■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.
■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.
■Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
■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. Damaged or
entangled cords increase the risk of electric
shock.
■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.
■If operating a power tool in a damp location
is unavoidable, use a residual current
device (RCD) protected supply. Use of an
RCD reduces the risk of electric shock.
POWER TOOL USE AND CARE
■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.

SAFETY INFORMATION
Please read these instructions fully before operating or maintaining your machine
PERSONAL SAFETY
■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.
■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 aredangerous in the hands of
untrained users.
■Maintain power tools. Check for
misalignment 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.
■Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
■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.
■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
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. Loose
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.
