General Power Tool Safety Warnings
WARNING
!
Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered
or 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 children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
us e a ny adapter pl ug s with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
Do not 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
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and
use co mmon sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention
while operating power tools may result in
serious personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the off- posit ion before
connecting to power source and / or battery
pack, picking up or carryi ng t he t ool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power
tool may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
co ntrol of the power to ol in unexpe ct ed
situations.
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
Power tool use and care
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at
the rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that
ca nn ot be co nt ro lled with the swi tc h is
dangerous and must be repaired.
2
DM 2610029872 03-13_DM 2610029872 03-13.qxp 4/2/13 8:11 AM Page 3
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the power tool’s operation. If damaged,
have the power tool repaired before use.
Ma ny acci de nt s a re ca us ed by poorly
maintained power tools.
Safety Rules for Rotary Tools
Hold power tool by insulated gripping
surfaces, because the cutter may contact
its own cord. Cutting a ”live” wire may make
exposed metal parts of the power tool ”live”
and shock the operator.
Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by your
hand or against the body leaves it unstable
and may lead to loss of control.
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.
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 5"
radius.
Always disconnect the power cord from
th e pow er source bef or e making an y
adjustments or attaching any accessories.
You may unexpectedly cause the tool to start
leading to serious personal injury.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified
re pa ir person using o nly id en tical
replacement parts. This will ensure that the
safety of the power tool is maintained.
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.
Do not reach in the area of the spinning
bit. The proximity of the spinning bit to your
hand may not always be obvious.
Allow brushes to run at opera ting 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
op er ated 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
di sc ha rged at high ve lo ci ty during t he
“cleaning” action with these brushes and may
become imbedded in your skin. Bristles or
wires will be discharged from the brush at high
speeds.

Safety Rules for Rotary Tools - (cont.)
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
wi re or b ri stle t o become overstres se d,
resulting in a wiping action and will cause the
bristles/wire to be discharged.
Ca re fully handle both the tool and
in di vidual gr in ding wh ee ls 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.
Us e cl am ps to supp or t w or kpiece
whenever practical. Never hold a small
workpiece in one hand and the tool in the
ot he r hand while in us e. A ll ow f or
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.
Inspect your workpiece before cutting.
Wh en cu tt ing i rregularly 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.
Ne ve r start the tool wh en 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 is it 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 al lo w familiarity gai ne d 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, cut off wheels,
high speed cutters or tungsten carbide
cutters, always have the work secure ly
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 slight ly canted in the
groove, and can kick back causing loss of
control resulting in serious in jury. Your second
hand should be used to steady and guide the
hand holding the tool. When a cutoff wheel

Additional Safety Warnings
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
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.

Operating Instructions
Dremel 4200
Thank you for purchasing the Dremel 4200.
Th is prod uct was designed by the many
Dremel users who passionately use their rotary
tools daily. This tool was designed to give you
an easy way to change accessories and the
ultimate performance when working on projects.
The Dremel 4200 is the FIRST rotary tool that
easily change accessories without using a
wrench. It uses a fully integrated mechanism
that clamps the accessory through a lever
system. In addition, the Dremel 4200 is a high
pe rform ance rotary too l with elect ronic
feedback that allows the tool to maintain its
speed under load. The design of the tool is
symmetrical and contains plenty of soft grip so
the tool can be held comfortably in many
po sitio ns. You will appreciate the many
applications that the Dremel 4200 can easily
tackle.
Rotary Tool Introduction
The Rotary Tool has a small, powerful electric
universal motor, is comfort able in the hand, and
is made to accept a large variety of accessories
including abrasive wheels, drill bits, wire
brushes, polishers, engraving cutters, router
bi ts, c uttin g wh eels and attachments.
Accessories come in a variety of shapes and
permit you to do a number of different jobs. As
yo u be come familiar wi th 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
re volut ions per minu te. The Rotary Tool
operates at speeds up to 35,000 revolutions
per minute. The typical electric drill is a low-
levers and run the Rotary Tool. You should be
able to tell by th e sound and fe el 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 Rotary
Tool and run the 415 Dressing Stone lightly
against the revolving wheel point. This removes
high spots and trues up the wheel point for
good balance.
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
acces sory 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 differ ent from other tools. The speed enables it to do
jobs low speed tools cannot do, such as cutting
hardened steel, en graving glass, etc.
Getting the most out of your Rotary Tool is a
matter of learning how to let this speed work for
yo u. To learn about more uses and the
ve rsati lity o f Drem el acce ssori es and
attachments refer to this Owner's Manual or
check our website at www.Dremel.com.
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.
Always hold the tool
away from your face.

handling, and can fly
apart as they come up
to speed. This is not
common, but it does happen.
!
CAUTION
Wh enever yo u hold th e
tool, be careful not to cover
the air vents with your hand. This blocks
th e air flow and ca uses the motor to
overheat.

For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger (Figure 6).

The “Golf Grip” method of holding the tool is
used for more aggressive operations such as
grinding a flat surface or using cutoff wheels
(Figure 7).

or check our website at www.Dremel.com
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.
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. Con centrate 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 effi cient work out of the accessory.
The hanger is provided for the use of hanging
your tool while us ing the flex-shaft or for
storage. If you do not use the hanger, snap it
back into place so it will be out of the way while
the tool is in use.
Operating Speeds
To select the right speed for each job, use a
practice piece of material.
NO TE: Spee d i s affect ed by volta ge
changes. A reduced incoming voltage will
slow the RPM of the tool.
SLIDE "ON/OFF" SWITCH
The tool is switched "ON" by the slide switch
located on the topside of the motor housing.
TO TURN THE TOOL "ON", slide the switch
button forward.
TO TURN THE TOOL "OFF", slide the switch
button backward.
HIGH PERFORMANCE MOTOR
Your tool is equipped with a high performance
rotary tool motor. This motor expands the
versatility of the rotary tool by driving additional
attachments such as the Dremel Mini-Saw and
Dremel Right Angle.
Your tool is equipped with an internal electronic
ELECTRONIC FEEDBACK
feedback system that provides a “soft start”,
which will reduce the stresses that occur from
a high torque start. The system also helps to
keep the preselected speed virtually constant
between no-load and load conditions.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed
dial. The speed may be adjuste d du ring

pr ecious metals , fo r ex ample) requi re a
relatively slow speed because at high speed
the friction of the 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 ac ces sories. They may also be best
for working on deli cate projects as “eggery”
work, delicate wood carving and fragile model
parts. All brushing applications require
lower speeds to avoid wire discharge from
the holder.
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.
Many applications and accessories in our line
will provide the best performance at full speed,
but for certain materials, applications, and
accessories, you need slower speeds, which is
the reason our variable speed models are
available.
To aid you in det erminin g the optim um
operational speed for differ ent materials and
different accessories, we have construct ed a
series of tables that appear on page 21, 22, 23
and 24. By referring to these tables, you can
discover the recommended speeds for each
type of accessory. Look these tables over and
become familiar with them.
Ultimately, the best way to determine the
correct speed for work on any material is to
practice for a few minutes on a piece of scrap,
even after referring to the chart. You can
quickly learn that a slower or faster speed is
more effective just by observing what hap pens
as you make a pass or two at different speeds.
When working with plastic, for example, start at
a slow rate of speed and increase the speed
until you observe that the plastic is melting at
the point of contact. Then reduce the speed
slight ly to get the optimum working speed.
Some rules of thumb in regard to speed:
1. Plastic and other materials that melt at low
temperatures should be cut at low speeds.
2. Polishing, buffing and cleaning with any type
of bristle brush must be done at speeds not
greater than 15,000 RPM to prevent damage
to th e bru sh from brist le s fly ing toward
operator.
3. Wood should be cut at high speed.
4. Iron or steel should be cut at high speed. If a
high speed steel cutter starts to chatter — this
normally means it is running too slow.
5. Aluminum, copper alloys, lead alloys, zinc
alloys and tin may be cut at various speeds,
depending on the type of cutting being done.
Use paraffin or other suitable lubricant on the
cutter to prevent the cut material from adhering
to the cutter teeth.
Increasing the pressure on the tool is not the
answer when it is not performing as you think it
sh ould. Pe rhaps yo u sho uld be us ing a
di ffere nt ac cessory, an d pe rhaps an
adjustment in speed would solve the problem.
Leaning on the tool does not help.
Let speed do the work!
Use only Dremel®, high-performance accessories.

wall outlet before performing service or
cleaning.
The brushes and commutator in your tool have
be en engineer ed for many ho urs of
dependable service.
In order to prepare your brushes for use, run
your tool at full speed for 5 minutes under no
load. This will properly “seat” your brushes,
which extends the life of both your brushes
and your tool.
To maintain peak efficiency of the motor, we
recommend every 40 - 50 hours the brush es
be examined. Only genuine Dremel replace ment brushes specially designed for your tool
should be used.
MAINTENANCE OF REPLACEABLE
The brushes should be inspected frequently
when tools are used continuously. If your tool
runs spo rad ically, loses power, makes unusual
noises or runs at a reduced speed, check the
brushes.

Follow these steps to check/change the rotary
tool brushes:
1. With the power cord unplugged, place the
tool on a clean surface. Use a screwdriver to
remove the brush caps in a counter-clockwise
direction (Figure 9).
2. Remove the brushe s fr om the tool by
pulling on the spring that is attached to the
carbon brush. If the brush is less than 1/8"
long and the end surface of the brush that
contacts the commutator is rough and/or
pitted, they should be replaced. Check both
brushes (Figure 10).

Usually the brushes will not wear out simul taneously. If one brush is worn out, replace
both brushes. Make sure the brushes are
installed as illus trated. The curved surface of
the brush must match the curvature of the
commutator. Also check that the brush caps sit
flush with the tool housing.
3. After replacing brushes the tool should be
run at no-load; place it on a clean surface and
run it freely at full speed for 5 minutes before
loading (or using) the tool. This will allow the
brushes to “seat” properly and will give you
more hours of life from each set of brushes.
This will also extend the total life of your tool
since the com mutator surfa ce will “wear ”
longer.
