Local working and safety rules and laws must always be
followed. The same applies to regulations which apply to the
environment.
Safety equipment must never by removed or bridged over.
When using oils, greases and other chemical substances, the
safety regulations which apply to the particular product must
always be observed! Contact with chemicals should be
avoided as far as possible. Before it is permissible to work
with these substances the instructions for use on the
packaging must be read and followed. This applies for all
chemicals, therefore also for cleaning media.
All notes and signs regarding safety and possible risks must
be kept in a fully legible condition.

Only use the electric tool when it is in
perfect condition from the technical point
of view, and only use it for intended
purpose while being aware of safety
issues and risks, and paying attention to
the instruction manual! In particular,
have any disturbances which could have
a negative effect on safety corrected
immediately!
WARNING! It is essential to read all the instructions.
Mistakes which are made while attempting to follow the
below instructions can cause electric shock, fire and/or
serious injury. The following term "Electric tool", refers to
mains-powered electric tools (with mains cable) and
battery-powered electric tools (without mains cable).
Warning Caution
KEEP THESE INSTRUCTIONS IN A SAFE
PLACE.
Work Area Safety
Keep your work area clean and well lit. Cluttered benches
and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquid, gases, or dust.
Power tools create sparks, which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to lose
control.
Electrical Safety
Warning Caution
Earthed tools must be plugged into an outlet properly
installed and earthed in accordance with all codes and
ordinances. Never remove the earthing prong or modify the
plug in any way. Do not use any adaptor plugs. Check with
a qualified electrician if you are in doubt as to whether the
outlet is properly earthed. If the tools should electrically
malfunction or break down, earthing provides a low resistance
path to carry electricity away from the user.
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.
Don’t expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Don’t abuse the cord. Never use the cord to carry the tools
or pull the plug from an outlet. Keep cord away from heat,
oil, sharp edges or moving parts. Replace
damaged cords
immediately. Damaged or entangled cords increase the risk of
electric shock.
When operating a power tool outside, only use authorized
cords for outdoor work. These cords are rated for outdoor use
and reduce the risk of electric shock.
Personal Safety
Stay alert, watch what you are doing and use common sense
when operating a power tool. Do not use tool while 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 safety equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hardhat, or
hearing protection used for appropriate conditions will reduce
personal injuries.
Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch or
plugging in tools that have the switch on invites accidents..
Warning Caution
Remove any adjusting key or wrenches before turning
the tool on. Awrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
Do not overreach. Keep a proper footing and balance at
all times. Proper footing and balance enables better control
of the 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.
Tool use and care
Do not force tool. Use the correct tool for your
application. The correct tool will do the job better and safer
at the rate for which it is designed.
Do not use tool if switch does not turn it on and off. Any
tool that cannot be controlled with the switch is dangerous
and must be repaired.
Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally.
Store idle tools out of reach of children and do not allow
persons unfamiliar with the power tool or these
instructions to operate the power tool. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools, with sharp cutting edges
are less likely to bind and are easier to control.
Maintain power tools. Check for misalignment or binding
of moving
parts, breakage of parts, and any other
condition that may affect the tools operation. If damaged,
have the tool serviced before using. Poorly maintained
tools cause many accidents.
Use the power tool, accessories and blades etc., in
accordance 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.
Use clamps or other practical way to secure and support
the work piece to a stable platform. Holding the work by
hand r against your body is unstable and may lead to loss of
control.
Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool may become hazardous when used on
another tool.

Conversion to jack rafter
is prohibited on the
9410ND!
ATTENTION!
Put the Knob a half turn to the left (1), with the thumb locking bow
down (2). The saw is now swiveled to both sides up to 45 °. Adjust
the desired miter angle on the scale. For common angle precisely
locating points are available.
