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-
Work Area
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 liquids, gases, or dust. Power
tools create sparks which may ignite the dust
or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Double Insulated tools are equipped with
a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized
outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified
electrician to install a polarized outlet. Do
not change the plug in any way. Double
Insulation
eliminates the need for the
three wire grounded power cord and
grounded power supply system. Before
plugging in the tool, be certain the outlet
voltage supplied is within the voltage marked
on the nameplate. Do not use "AC only"
rated tools with a DC power supply.
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. If operating the power tool in
damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to
supply the power to your tool. Electrician's
rubber gloves and footwear will further
enhance your personal safety.
Don't 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 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.
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.
Refer to "Recommended sizes of Extension
Cords" in the Accessory section of this
manual.
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.
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.
Keep handles dry, clean and free from oil
and grease.
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.
Remove adjusting keys or wrenches
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.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the tool
in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.

Safety Rules for Nibblers
Tool Use and Care
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.
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" or "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
other untrained persons. 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. Any
alteration or modification is a misuse and
may result in a dangerous condition.
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. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
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.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of electric shock or injury. Certain cleaning
agents
such
as
gasoline,
carbon
tetrachloride, ammonia, etc. may damage
plastic parts.
Always unplug the tool from the power
source before changing accessories or
making any adjustments. Accidental start
up may occur causing serious personal
injury.
Always wear safety goggles or eye
protection when using this tool. Wear
leather gloves and safety shoes. Leather
gloves and safety shoes will protect hands
from sharp metal edges and feet from sharp
metal pieces.
Secure the material being cut. Never hold
small pieces in your hand or across your
legs. Do not touch punch and die during
use of the nibbler.
Contact with the punch
and die may cause a laceration or crush injury.
Periodically check tool fasteners for
looseness and tighten as required. The
vibration of the nibbler may cause fasteners to
occasionally loosen.
Do not cut material greater than the rated
capacity of the nibbler. Cutting material
thicker than the capacity will cause damage to
punch and die set.
Do not use dull or damaged punch and
dies or accessories not intended for a
nibbler. Replace worn punches and dies.
Dull or damaged bits have a greater tendency
to bind in the workpiece.
When removing the punch/die set from the
tool avoid contact with skin and use proper
protective gloves when grasping the bit or
accessory. Accessories may be hot after
prolonged use.

Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
· Lead from lead-based paints,
· Crystalline silica from bricks and cement
and other masonry products, and
· Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such
as those dust masks that are specially
designed to filter out microscopic particles.
