■
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.
SAVE THESE INSTRUCTIONS
WORK AREA
Remove adjusting keys or wrenches before turn-
ing the tool on. A wrench or a key that is left at-
tached to a rotating part of the tool may result in
personal injury.
■
Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
■
Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools may create
sparks which may ignite the dust or fumes.
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. Do not use on a ladder or unstable support.
■
Keep bystanders, children, and visitors away
while operating a power tool. Distractions can
cause you to lose control.
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.
ELECTRICAL SAFETY
■
Double insulated tools are equipped with a po-
larized 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 insu-
TOOL USE AND CARE
■
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 un-
stable 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.
lation
eliminates the need for the three-wire
grounded power cord and grounded power supply
system.
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.
■
Avoid body contact with grounded surfaces,
such as pipes, radiators, ranges, and refrigera-
tors. There is an increased risk of electric shock if
your body is grounded.
Disconnect the plug from power source before
making any adjustments, changing accessories,
or storing the tool. Such preventive safety mea-
sures reduce the risk of starting the tool acciden-
tally.
■
■
Don’t expose power tools to rain or wet condi-
tions. 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 immedi-
ately. Damaged cords increase the risk of electric
shock.
■
■
Store idle tools out of the 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.
■
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.
■
■
Check for misalignment or binding of moving
parts, breakage of parts, and any other condi-
tion that may affect the tool’s operation. If dam-
aged, have the tool serviced before using. Many
accidents are caused by poorly maintained tools.
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 inat-
tention while operating power tools may result in
serious personal injury.
Use only accessories that are recommended by
the manufacturer for your model. Accessories that
may be suitable for one tool, may become hazard-
ous when used on another tool.

GENERAL SAFETY RULES
■
When servicing a tool, use only identical replace-
SERVICE
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.
■
Tool service must be performed only by quali-
fied repair personnel. Service or maintenance per-
formed by unqualified personnel could result in a risk
of injury.
SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact
hidden wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the
operator.
■
Make sure your extension cord is in good condi-
tion. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. A wire gage size (A.W.G.) of at
least 16 is recommended for an extension cord
100 feet or less in length. A cord exceeding 100
feet is not recommended. If in doubt, use the next
heavier gage. The smaller the gage number, the
heavier the cord. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating.
ADDITIONAL SAFETY RULES
■
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations,
as well as the specific potential hazards related
to this tool. Following this rule will reduce the risk
of electric shock, fire, or serious injury.
■
Always wear safety glasses. Everyday eye-
glasses have only impact-resistant lenses; they
are NOT safety glasses. Following this rule will re-
duce the risk of serious personal injury.
■
■
Protect your lungs. Wear a face or dust mask if
the operation is dusty. Following this rule will re-
duce the risk of serious personal injury.
■
■
Inspect for and remove all nails from lumber be-

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.
■
■
Secure work. Use clamps or a vise to hold work
when practical. It is safer than using your hand and
frees both hands to operate tool.
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.
Do not abuse cord. Never carry the tool by the
cord or yank it to disconnect it from the recep-
tacle. Keep cord away from heat, oil, and sharp
edges. Following this rule will reduce the risk of elec-
tric shock or fire.

cause product damage.
GENERAL
BITS
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, carbon dust, etc.
Get faster and more accurate cutting results by keeping
bits clean. Remove all accumulated build-up from bits
after each use. Replace bits when they become dull.
WARNING:
The bit flutes are sharp and should be handled with
caution.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleum-based products, penetrating oils, etc.
come in contact with plastic parts. They contain
chemicals that can damage, weaken, or destroy
plastic.
COLLET
From time to time, it also becomes necessary to clean
your collet and collet nut. To do so, simply remove collet
nutandcolletfromtheshaftandcleanthedustandchips
that have collected. Then return collet nut to its original
position.Tightencolletnutoncolletwithoutabitinstalled.
