Power Tool Safety Rules
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
Keep your work area clean and well lit. Cluttered
Work Area
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.
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.
Page 2
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.
Safety Rules for Rotary Tools
Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels
and other accessories running over rated speed can
fly apart and cause injury.
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. If cutting into existing
walls or other blind areas where electrical wiring may
exist is unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.
Do not operate the flexible shaft with a sharp bend.
Over bending the shaft can generate excessive heat
on the jacket or hand piece. The recommended
minimum is 6" radius.
Always disconnect the power cord from the power
source before making any adjustments or attaching
any accessories. You may unexpectedly cause the
tool to start leading to serious personal injury.
Be aware of the switch location, when placing the
tool down or when picking the tool up. You may
accidentally activate the switch.
Always hold the hand piece firmly in your hands
during the start-up. The reaction torque of the motor,
as it accelerates to full speed, can cause the shaft to
twist.
Always wear safety goggles and dust mask. Use
only in well ventilated area. Using personal safety
devices and working in safe environment reduces risk
of injury.
After changing the bits or making any adjustments,
make sure the collet nut and any other adjustment
devices are securely tightened. Loose adjustment
device can unexpectedly shift, causing loss of control,
loose rotating components will be violently thrown.
Do not reach in the area of the spinning bit. The
proximity of the spinning bit to your hand may not
always be obvious.
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.
Allow brushes to run at operating speed for at least
one minute before using wheel. During this time no
one is to stand in front or in line with the brush.
Loose bristles or wires will be discharged during the
run-in time.
Wire and bristle brushes must never be operated at
speeds greater than 15,000/min. Direct the
discharge of the spinning wire brush away from
you. Small particles and tiny wire fragments may be
discharged at high velocity during the “cleaning”
action with these brushes and may become imbedded
in your skin. Bristles or wires will be discharged from
the brush at high speeds.
Wear protective gloves and face shield with wire or
bristle brushes. Apply wire or bristle brushes lightly
to the work as only the tips of the wire/bristles do
the work. “Heavy” pressure on bristles will cause the
wire or bristle to become overstressed, resulting in a
wiping action and will cause the bristles/wire to be
discharged.
Carefully handle both the tool and individual
grinding wheels to avoid chipping or cracking.
Install a new wheel if tool is dropped while
grinding. Do not use a wheel that may be damaged.
Fragments from a wheel that bursts during operation
will fly away at great velocity possibly striking you or
bystanders.
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.
Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other hand while in use. Allow
for sufficient space, at least 6", between your hand
and the spinning bit. Round material such as dowel
rods, pipes or tubing have a tendency to roll while
being cut, and may cause the bit to “bite” or jump
toward you. Clamping a small workpiece allows you
to use both hands to control the tool.
Page 3
Safety Rules for Rotary Tools - (cont.)
Inspect your workpiece before cutting. When cutting
irregularly shaped workpieces, plan your work so it
will not slip and pinch the bit and be torn from your
hand. For example, if carving wood, make sure there
are no nails or foreign objects in the workpiece. Nails
or foreign objects can cause the bit to jump.
Never start the tool when the bit is engaged in the
material. The bit cutting edge may grab the material
causing loss of control of the cutter.
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kick-back.
The direction of feed with the bit into the material
when carving, routing or cutting is very important.
Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips
are thrown). Feeding the tool in the wrong direction,
causes the cutting edge of the bit to climb out of the
work and pull the tool in the direction of this feed.
If the workpiece or bit becomes jammed or bogged
down, turn the tool “OFF” by the switch. Wait for
all moving parts to stop and unplug the tool, then
work to free the jammed material. If the switch to
the tool is left “ON” the tool could restart
unexpectedly causing serious personal injury.
Do not leave a running tool unattended, turn power
off. Only when tool comes to a complete stop it is
safe to put it down.
Do not grind or sand near flammable materials.
Sparks from the wheel could ignite these materials.
Do not touch the bit or collet after use. After use the
bit and collet are too hot to be touched by bare hands.
Regularly clean the tool's air vents by compressed
air. Excessive accumulation of powdered metal inside
the motor housing may cause electrical failures.
Do not allow familiarity gained from frequent use of
your rotary tool to become commonplace. Always
remember that a careless fraction of a second is
sufficient to inflict severe injury.
Do not alter or misuse tool. Any alteration or
modification is a misuse and may result in serious
personal injury.
This product is not intended for use as a dental
drill, in human or veterinary medical applications.
Serious personal injury may result.
When using the steel saws, cutoff wheels, high
speed cutters or tungsten carbide cutters, always
have the work securely clamped. Never attempt to
hold the work with one hand while using any of
these accessories. The reason is that these wheels
will grab if they become slightly canted in the groove,
and can kickback causing loss of control resulting in
serious injury. Your second hand should be used to
steady and guide the hand holding the tool. When a
cutoff wheel grabs, the wheel itself usually breaks.
When the steel saw, high speed cutters or tungsten
carbide cutter grab, it may jump from the groove and
you could lose control of the tool.
WARNING
!

KEYLESS CHUCK
NUT
TO LOOSEN
COLLET NUT — To loosen, first press shaft lock
button and rotate the shaft by hand until the lock
engages the shaft preventing further rotation.
CAUTION
!
With the shaft lock engaged use the collet wrench to
loosen the collet nut if necessary. The collet nut must
be loosely threaded on when inserting an accessory.
Change accessories by inserting the new one into the
collet as far as possible to minimize runout and
unbalance. With the shaft lock engaged, finger tighten
the collet nut until the accessory shank is gripped by
the collet. Avoid excessive tightening of the collet
nut when there is no bit inserted.
COLLETS — Four different size collets (see illus-
tration), to accommodate different shank sizes, are
available for your Rotary Tool. To install a different
collet, remove the collet nut and remove the old collet.
Insert the unslotted end of the collet in the hole in the
end of the tool shaft. Replace collet nut on the shaft.
CAUTION
!
accessory you plan to use. Never force a larger
diameter shank into a collet.
Note: Some rotary tool kits may not include all four
collets sizes.
BALANCING ACCESSORIES — For precision work, it
is important that all accessories be in good balance
(much the same as the tires on your automobile). To
true up or balance an accessory, slightly loosen collet
nut and give the accessory or collet a 1/4 turn. Retighten collet nut and run the Rotary Tool. You should
be able to tell by the sound and feel if your accessory
is running in balance. Continue adjusting in this
fashion until best balance is achieved. To maintain
balance on abrasive wheel points, before each use,
with the wheel point secured in the collet, turn on the

Operating Instructions
The Rotary Tool is a handful of high-speed power. It
serves as a carver, grinder, polisher, sander, cutter,
power brush, drill and more.
The Rotary Tool has a small, powerful electric
universal motor, is comfortable in the hand, and is
made to accept a large variety of accessories
including abrasive wheels, drill bits, wire brushes,
polishers, engraving cutters, router bits, cutting
wheels and attachments. Accessories come in a
variety of shapes and permit you to do a number of
different jobs. As you become familiar with the range
of accessories and their uses, you will learn just how
versatile the Rotary Tool is. You’ll see dozens of uses
you hadn’t thought of before.
The real secret of the Rotary Tool is its speed. To
understand the advantages of its high speed, you
have to know that the standard portable electric drill
runs at speeds up to 2,800 revolutions per minute.
The Rotary Tool operates at speeds up to 35,000
revolutions per minute. The typical electric drill is a
low-speed, high torque tool; the Rotary Tool is just
the opposite – a high-speed, low torque tool. The
major difference to the user is that in the high speed
tools, the speed combined with the accessory
mounted in the collet does the work. You don’t apply
pressure to the tool, but simply hold and guide it. In
the low speed tools, you not only guide the tool, but
also apply pressure to it, as you do, for example,
when drilling a hole.
It is this high speed, along with its compact size and
wide variety of special accessories and attachments,
that makes the Rotary Tool different from other tools.
The speed enables it to do jobs low speed tools
cannot do, such as cutting hardened steel, engraving
glass, etc.
periods of time. Overloading the chuck may cause the
bit to loosen and slip. It is recommended that in these
types of applications that the bit be secured in the
chuck with the supplied wrench and work in intervals
to allow cooling of the bit and chuck. If the bit slips
the tool will begin to vibrate excessively, this is an
indication that you should shut the tool off, reposition and tighten the bit then allow the tool to run
no-load for a few minutes to cool.
The chuck should be cleaned occasionally to keep it
functioning properly. Simply remove the chuck from
the tool and gently tap the tip of the chuck on a fat
surface to remove any loose debris. In some
applications the keyless chuck may tighten up during
use. If this occurs, gently loosen using the wrench
included in your rotary tool kit.

Operating Instructions - (Cont.)
Using the Rotary Tool
The first step in learning to use the Rotary Tool is to
get the “feel” of it. Hold it in your hand and feel its
weight and balance. Feel the taper of the housing.
This taper permits the Rotary Tool to be grasped
much like a pen or pencil. The 395T6 Variable Speed
tool has a unique comfort grip on the nose and back
seating, which allows the user added comfort and
control during use. You can feel the difference!
Always hold the tool away from your face.
Accessories can be damaged during handling, and
can fly apart as they come up to speed. This is not
common, but it does happen.
Practice on scrap materials first to see how the
Rotary Tool's high speed action performs. Keep in
mind that the work is done by the speed of the tool
and by the accessory in the collet. You should not
lean on or push the tool during use.
Questions or Problems?Call 1-800-437-3635
or check our website at www
Instead, lower the spinning accessory lightly to the
work and allow it to touch the point at which you want
cutting (or sanding or etching, etc.) to begin. Concentrate on guiding the tool over the work using very
little pressure from your hand. Allow the accessory to
do the work.
Usually, it is best to make a series of passes with the
tool rather than attempt to do all the work in one
pass. To make a cut, for example, pass the tool back
and forth over the work, much as you would a small
paint brush. Cut a little material on each pass until
you reach the desired depth. For most work, the
gentle touch is best. With it, you have the best
control, are less likely to make errors, and will get the
most efficient work out of the accessory.

Whenever you hold the tool, be careful not to cover
the air vents with your hand. This blocks the air
Page 10
Operating Speeds
Set the speed indicator to fit the job; to achieve the
best job results when working with different materials, the speed of the Rotary Tool should be regulated. Only a full wave output speed control such as
the Dremel Model 221 should be used with the
275T6 Rotary Tool.
To select the right speed for each job, use a practice
piece of material. Vary speed to find the best speed
for the accessory you are using and the job to be
done.
NOTE: Speed is affected by voltage changes. A
reduced incoming voltage will slow the RPM of the
tool, especially at the lowest setting. If your tool
appears to be running slowly increase the speed
setting accordingly. The tool may not start at switch
position #1 in those areas where outlet voltage is
less than 120 volts. Simply move the switch lever to
a higher position to begin operation.
There are three basic types of Rotary Tools: single
speed, two-speed and variable speed models.
On the single speed model, there is an ON-OFF
switch. When the switch is on, the tool runs at 35,000
RPM.
On the two-speed model, there is a LO and HI switch.
When the switch indicator is on the low setting, the
tool runs at about 15,000 RPM. When the switch
indicator is on the high setting, the tool runs at about
35,000 RPM.
accessory generates heat and may cause damage to
the material.
Slow speeds (15,000 RPM or less) usually are best
for polishing operations employing the felt polishing
accessories. They may also be best for working on
delicate projects as “eggery” work, delicate wood
carving and fragile model parts. (All brushing
applications require lower speeds to avoid wire
discharge from the holder.) No greater than speed
setting 4 for the model 395-T6.
Higher speeds are better for carving, cutting, routing,
shaping, cutting dadoes or rabbets in wood.
Hardwoods, metals and glass require high speed
operation, and drilling should also be done at high
speeds.
The speed of Rotary Tool is controlled by setting
this indicator on the housing.
On the variable speed model, there are switch setting
indicators marked with a line. Slide to the number on
the housing to select the operating speed needed
from 5,000 – 35,000 RPM. You can refer to the
charts on page 24, 25, and 26 to determine the
proper speed, based on the material being worked
and the type of accessory being used. These charts
enable you to select both the correct accessory and
the optimum speed at a glance.
If you have a single-speed or two-speed model, you
will be able to use many accessories to do a wide
assortment of jobs. For the majority of applications,
all models of the Rotary Tool should be used at top
speed.
Needs for Slower Speeds
Certain materials, however, (some plastics and
precious metals, for example) require a relatively slow
speed because at high speed the friction of the
