ELECTRICAL SAFETY
WARNING: Use proper circuit protection in order to avoid electrical
hazards, fire hazards, or damage to the rotary tool.
This rotary tool is wired at the factory for 110–120 V operation. It must be
connected to a 110–120 V 15 A time-delayed fuse or circuit breaker. In order
to avoid shock or fire, replace the power cord immediately if it is worn, cut, or
damaged in any way.
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain chemicals that are
known to cause cancer, birth defects. or other genetic abnormalities. These
chemicals include:
Lead from lead-based paints
Crystalline silica from bricks, cement, and other masonry products
Arsenic and chromium from chemically-treated lumber
The level of risk from exposure to these chemicals varies according to how
often this type of work is performed. In order to reduce exposure to these
chemicals, work in a well-ventilated area, and use approved safety
equipment, such as a dust mask that is specifically designed to filter out
microscopic particles.
!
SAFETY WARNINGS

5
GENERAL SAFETY RULES
WARNING: Read all instructions
carefully and understand them
completely. Failure to follow all of the
instructions listed below may result in
electric shock, fire, and/or serious personal
injury.
WORK AREA
Keep the work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate a power tool in a potentially
explosive environment, such as in the
presence of flammable liquids, gas, or
dust. Power tools create sparks that may
ignite the dust or fumes.
Keep bystanders, children, and visitors
away while operating a power tool.
Distractions can cause the operator to lose
control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will only fit into a
polarized outlet one way.
If the plug does not fit into the outlet
properly, reverse the plug. If it still does not
fit, contact a qualified electrician in order to
install a polarized outlet. Do not alter the
plug in any way. Double insulation
eliminates the need for the three-pronged
grounded power cord and grounded power
supply system.
Avoid contact between the operator's body
and grounded surfaces such as pipes,
radiators, ranges, and refrigerators. There
is an increased risk of electric shock if the
operator's 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. Do not use the
power cord to carry the tool or to pull the
plug out of the outlet. Keep the power cord
away from heat, oil, sharp edges, and
moving parts. Replace a damaged power
cord immediately. A damaged power cord
increases the risk of electric shock.
When operating a power tool outdoors,
use an outdoor extension cord that is
marked “W-A” or “W”. These cords are
rated for outdoor use, and they reduce the
risk of electric shock.
PERSONAL SAFETY
Stay alert, be aware of the surroundings,
and use common sense when operating a
power tool. Do not use a power tool while
tired or under the influence of drugs,
alcohol, or medication. A moment of
inattention while operating a power tool
could result in serious personal injury.
Dress properly. Do not wear loose clothing
or jewellery.
Contain long hair. Keep hair, clothing, and
gloves away from moving parts. Loose
clothing, jewellery, or long hair can get
caught in moving parts.
!
POWER TOOL SAFETY

6
PERSONAL SAFETY –cont’d
Avoid accidental start-ups. Verify that the
switch is in the OFF position before
plugging the tool in. Carrying a power tool
with a finger on the switch or plugging in a
tool that has the switch in the ON position
invites accidents.
Remove adjusting keys and 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 allows the operator to maintain
better control of the tool in unexpected
situations.
Use safety equipment. Always wear eye
protection.
Use a dust mask, non-skid safety shoes, a
hardhat, or hearing protection when
appropriate.
USE AND CARE OF POWER TOOLS
Use clamps or another practical means to
secure and support the workpiece to a
stable platform. Holding the work in a hand
or against the body is not stable, and may
lead to loss of control.
Do not force the tool. Use the correct tool
for the application. The correct tool will do
the job better and safer when it is used at
the rate that it was designed to work at.
Do not use a power tool if it cannot be
turned ON or OFF using the power switch.
A tool that cannot be controlled using the
switch is dangerous, and must be repaired.
Disconnect the plug from the outlet before
making any adjustments, changing
accessories, or storing the tool. Such
preventive safety measures reduce the risk
of accidental start-ups.
When power tools are not in use, store
them 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
cutting tools with sharp cutting edges are
less likely to bind, and are easier to
control.
Inspect the tool for misalignment or binding
of moving parts, broken parts, and any
other condition that may affect the
operation of the tool. If it is damaged, have
the tool serviced before using it. Many
accidents are caused by poorly maintained
tools.
Use only accessories that are
recommended by the manufacturer for this
model. Accessories that are suitable for
one tool may become hazardous when
used with another tool.
SERVICE
Tools must be serviced by qualified
personnel. Service or maintenance
performed by non-qualified personnel
could result in a risk of injury.
When servicing a tool, use only identical
replacement parts. Follow the instructions
in the Maintenance section of this Manual.
The use of unauthorized parts, or failure to
follow the instructions in the Maintenance
section of this Manual may create a risk of
electric shock or injury.
POWER TOOL SAFETY

7
WARNING: For safety reasons,
read this Owner's Manual carefully and
understand it thoroughly before
plugging in the rotary tool.
Hold the tool by the insulated gripping
surfaces when performing any operation
where the cutting tool may coming into
contact with hidden wiring or its own power
cord. Contact with a “live” wire will make
the exposed metal parts of the tool “live”,
which could shock the operator.
Verify that the work surface is free of nails
and other foreign objects. Cutting into a
nail may cause the bit and the tool to jump,
and could damage the bit.
Do not hold the workpiece in one hand and
the tool in the other hand while using the
tool. Do not place the hands near or below
the cutting surface. It is much safer to
clamp the material and to guide the tool
using both hands.
Do not lay the workpiece on a hard surface
such as concrete, stone, etc. The
protruding cutting bit may cause the tool to
jump.
Wear safety goggles and a dust mask.
Work only in a well-ventilated area. Using
personal safety devices and working in a
safe environment reduces the risk of injury.
Verify that the collet nut and all other
adjustment devices are securely tightened
after changing bits and accessories or
making adjustments. Loose adjustment
devices may be thrown violently when the
tool is turned ON.
Be sure to use the correct collet size. If the
collet size is larger than the accessory's
shank, it will not grip the shank properly,
which could result in injury to the operator
or damage to the tool.
Inspect accessory bits, grinding stones,
cut-off wheels, etc. for damage before
each use. A damaged accessory can
break during use, which could cause
serious injury.
Do not use dull or damaged bits. Handle
sharp bits with care. A damaged bit can
snap during use. A dull bit requires more
force in order to push the tool, which could
cause the bit to break.
Do not touch the bit during or immediately
after use. After use, the bit is hot enough
to burn bare skin.
Do not operate the flexible shaft with a
bend radius of less that 6” (15.2 cm). A
shorter bend radius will damage the
flexible shaft and the motor of the rotary
tool.
SPECIFIC SAFETY RULES
!

8
WARNING: Keep the extension
cord clear of the work area. Position the
cord so that it will not get caught on the
workpiece, a tool, or any other obstruction
while the power tool is in use.
If an extension cord is used with this rotary
tool, verify that it is in good condition.
When using an extension cord, be sure to
use one that is heavy enough to carry the
current that the tool will draw. An
undersized cord will cause a drop in line
voltage, which will result in a loss of power
and overheating.
The following table shows the correct size
to use according to cord length and the
amperage rating that is listed ton the tool's
nameplate. When in doubt, use the next
heavier gauge. The smaller the gauge
number, the heavier the cord.
Verify that the extension cord is properly
wired and in good condition. Replace a
damaged extension cord immediately, or
have it repaired by a qualified electrician
before using it. Keep the extension cord
away from sharp objects, excessive heat,
and damp or wet areas.
Use a separate electrical circuit for power
tools. This circuit must consist of not less
than 14 gauge wire, and should be
protected by either a 15 A time-delayed
fuse or a circuit breaker. Before connecting
the power tool to the outlet, verify that the
switch is in the OFF position, and that the
voltage of the power source is the same as
the voltage that is indicated on the tool's
nameplate. Running this rotary tool at
lower voltage will damage the motor.

In order to change the collet or to install an
accessory in the flexible shaft, follow the
steps listed in the sections entitled
“Changing the collet” and “Installing
accessories”. In order to lock the shaft in
place, pull back on the flexible shaft grip
(1) and rotate the collet until the shaft grip
locks the shaft in place (Fig. 4). The
flexible shaft grip will return to its normal
position when it is not being held in the
locked position.
NOTES:
a) Do not attempt to loosen or tighten the
collet without locking the shaft in place as
described above. Doing so will damage the
flexible shaft.
b) Do not over-tighten the collet nut.
