POWER TOOL SAFETY
WARNING: To avoid electrical hazards, fire hazards or damage to the rotary
tool, use proper circuit protection.
This rotary tool is wired at the factory for 120 V operation. It must be connected to a
120 V 15 A time delayed fuse or circuit breaker. To avoid shock or fire, replace
power cord immediately if it is worn, cut or damaged in any way.
!
WARNING: 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, cement and other masonry products
Arsenic and chromium from chemically-treated lumber
Your level of 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 dust masks that
are specially designed to filter out microscopic particles.
!
!
ALWAYS WEAR EYE PROTECTION
Any power tool can throw foreign objects into your eyes which could cause
permanent eye damage. ALWAYS wear safety goggles (not glasses) that
comply with ANSI safety standard Z87.1. Everyday glasses have only
impact resistant lenses. They ARE NOT safety glasses.
WARNING: Glasses or goggles not in compliance with ANSI Z87.1 could
cause serious injury when they break.

POWER TOOL SAFETY
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.
WORK AREA
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in potentially
explosive environments, such as in the
presence of flammable liquids, gas or
dust. Power tools create sparks which may
ignite the dust or fumes.
Keep bystanders, children and visitors
away while operating the 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 plug 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 alter the plug in any way.
Double insulation eliminates the need for
the three-prong grounded power cord and
grounded power supply system.
Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is increased risk of
electric shock if your body is grounded.
Do not expose power tools to rain or wet
conditions. Water entering the power tool
will increase the risk of electric shock.
Do not abuse the cord. Never use the
cord to carry the tool 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 outdoors,
use an outdoor extension cord marked
“W-A” or “W”. 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 the 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 jewellery.
Contain long hair. Keep your hair,
clothing and gloves away from moving
parts. Loose clothing, jewellery or long hair
can be caught in moving parts.
Avoid accidental starting. Be sure the
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.

POWER TOOL SAFETY
PERSONAL SAFETY –cont’d
Remove adjusting keys or wrenches
before turning the tool ON. A wrench or
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.
TOOL USE AND CARE
Use clamps or another 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 the tool. Use the correct
tool for your application. The correct tool
will do the job better and safer at the rate
for which it was designed.
Do not use the tool if the power 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 cutting tools with sharp cutting
edges are less likely to bind and are easier
to control.
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 accidents
are caused by poorly maintained tools.
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 personnel. Service or
maintenance performed by unqualified
personnel could result in risk of injury.
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.

SPECIFIC SAFETY RULES
WARNING: Know your rotary tool.
Read the Owner’s Manual carefully.
Learn the tool’s 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 eye protection. Any power
tool can throw foreign objects
into your eyes which could
cause permanent eye damage.
ALWAYS wear safety goggles
(not glasses) that comply with ANSI safety
standard Z87.1. Everyday glasses have
only impact resistant lenses. They ARE
NOT safety glasses.
WARNING: Glasses or goggles
not in compliance with ANSI Z87.1 could
cause serious injury when they break.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring
or its own cord. Contact with a “live” wire
will make exposed metal parts of the tool
“live” and shock the operator.
Always make sure the work surface is
free from nails and other foreign
objects. Cutting into a nail can cause the
bit and the tool to jump and damage the bit.
Never hold the workpiece in one hand
and the tool in the other hand when in
use. Never place the hands near or
below the cutting surface. Clamping the
material and guiding the tool with both
hands is much safer.
Never lay workpiece on hard surfaces
like concrete, stone, etc. Protruding
cutting bit may cause the tool to jump.
Always wear safety goggles and dust
mask. Use only in well-ventilated area.
Using personal safety devices and working
in a safe environment reduces risk of injury.
After changing the bits and accessories
or making adjustments, make sure the
collet nut and any other adjustment
devices are securely tightened. Loose
adjustment devices will be violently thrown.
Always use the correct collet size. If the
collet size is larger than the accessory
shank size it will not grip the shank
properly, leading to possible injury to the
operator or damage to the tool.
Always check accessory bits, grinding
stones, cut-off wheels etc. for damage
before each use. Damaged accessories
can break during use and cause serious
injury.
Never use dull or damaged bits. Sharp
bits must be handled with care.
Damaged bits can snap during use. Dull
bits require more force to push the tool,
possibly causing the bit to break.
Never touch the bit during or
immediately after use. After use the bit is
too hot to be touched by bare hands.
Never operate the flexible shaft with a
bend radius of less that 6”. Shorter bend
radii will damage the flexible shaft and the
rotary tool motor.

EXTENSION CORD SAFETY
WARNING: Keep the extension
cord clear of the working area. Position
the cord so it will not get caught on the
workpiece, tools or any other
obstructions while you are working with
the power tool.
Make sure any extension cord used with
this tool is in good condition. When
using an extension cord, be sure to use one
of heavy enough gauge to carry the current
the tool will draw. An undersized cord will
cause a drop in line voltage resulting in loss
of power and overheating.
The table at right shows the correct size to
use according to cord length and
nameplate ampere rating. If in doubt, use
the next heavier gauge. The smaller the
gauge number the heavier the cord.
Be sure your extension cord is properly
wired and in good condition. Always
replace a damaged extension cord or have
it repaired by a qualified electrician before
using it. Protect your extension cord from
sharp objects, excessive heat and damp or
wet areas.
Use a separate electrical circuit for your
power tools. This circuit must not be less
than 14 gauge wire and should be
protected with either a 15 A time delayed
fuse or circuit breaker. Before connecting
the power tool to the power source, make
sure the switch is in the OFF position and
the power source is the same as indicated
on the nameplate. Running at lower voltage
will damage the motor.
