5 Safety instructions

5.1 General safety rules
a) Warning! Read and understand all instructions.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal
injury. SAVE THESE INSTRUCTIONS.
5.1.1 Work area
a) Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
b) Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep bystanders, children and visitors away while
operating a power tool. Distractions can cause you
to lose control.
5.1.2 Electrical safety
a) Grounded tools must be plugged into an outlet
properly installed and grounded in accordance
with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do
not use any adapter plugs. Check with a qualified
electrician if you are in doubt as to whether the
outlet is properly grounded. If the tools should
electrically malfunction or break down, grounding
provides a low resistance path to carry electricity
away from the user.
b) Avoid body contact with grounded surfaces such
as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your
body is grounded.
c) Don't expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
d) Do not 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
cords increase the risk of electric shock.
e) When operating a power tool outside, use an
outdoor extension cord marked "W-A" or "W".
These cords are rated for outdoor use and reduce
the risk of electric shock.
5.1.3 Personal safety
a) 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 inatten-
tion while operating power tools may result in serious
personal injury.
b) Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing
and gloves away from moving parts. Loose clothes,
jewelry or long hair can be caught in moving parts.
c) 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.
d) Remove adjusting keys or switches before turning
the tool on. A wrench or a key that is left attached
to a rotating part of the tool may result in personal
injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. Proper footing and balance en-
ables better control of the tool in unexpected situa-
tions.
f) Use safety equipment. Always wear eye protec-
tion.Dust mask, non-skid safety shoes, hard hat or
hearing protection must be used for appropriate con-
ditions.
5.1.4 Tool use and care
a) Use clamps or other practical way to secure and
support the workpiece to a stable platform. Hold-
ing the work by hand or against your body is unstable
and may lead to loss of control.
b) 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.
c) Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
d) 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.
e) Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
f) Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cut-
ting edges are less likely to bind and are easier to
control.
g) Check for misalignment or binding of moving
parts, breakage of parts and any other condition
that may affect the tool's operation. If damaged,
have the tool serviced before using. Many acci-
dents are caused by poorly maintained tools.
h) 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.
5.1.5 Service
a) Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
b) When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Mainte-
nance section of this manual. Use of unauthorized
parts or failure to follow Maintenance Instructions
may create a risk of electric shock or injury.
