2. General safety rules
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.
2.1 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 atmos-
pheres, 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.
2.2 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 adaptor 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 immedi-
ately.
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.
2.3 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 inat-
tention 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, cloth-
ing 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 fin-
ger on the switch or plugging in tools that have
the switch on invites accidents.
d)
Remove adjusting keys or wrenches before turn-
ing 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
enables better control of the power tool in unex-
pected situations.
f)
Use safety equipment. Always wear eye protec-
tion.
Dust mask, non-skid safety shoes, hard hat
or hearing protection must be used for appropri-
ate conditions.
2.4 Power tool use and care
a)
Use clamps or other practical way to secure and
support the workpiece to a stable platform.
Holding 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 oth-
er 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 cutting 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 haz-
ardous when used on another tool.
2.5 Service
a)
Tool service must be performed only by quali-
fied repair personnel.
Service or maintenance
performed by unqualified personnel could result in
a risk of injury.
b)
When ser vicing a tool, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual.
Use of
unauthorized parts or failure to follow Mainte-
nance Instructions may create a risk of electric
shock or injury.
