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 adapt e r plugs wi t h e arthed
(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 the power tool in damp locations
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
us e c o mmon sen se w hen ope r atin g a

power tool. Do not use a power tool while
you are tired or under the influence of drugs,
a
lcohol 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
sw itch is in the off- posi tion befo re
connecting to power source and / or battery
pa ck, pic king up or carryi ng the too l.
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 powe r too l in unex p ected
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 for ce th e pow er to o l. Us e 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 n n ot be control l e d with the switc h is
dangerous and must be repaired.
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
w
ith 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 n y a c c idents are caused by poorly
maintained power tools.
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.
Battery tool use and care
Recharge only with the charger specified
by the man ufac t urer. A cha rger tha t is
suitable for one type of battery pack may
create a risk of fire when used with another
battery pack.
Use power too ls only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws, or other
small m e t a l objects that c a n make a
connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
Under abusive conditions, liquid may be
ejected from the battery, avoid contact. If
contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Service
Have your power tool serviced by a qualified
re p a i r pe r s o n us i n g on l y iden t i c al
replacement parts. This will ensure that the
safety of the power tool is maintained.

Safety warnings common for
grinding, sanding, wire brushing,
polishing, carving or abrasive
cutting-off operations:
This power tool is intended to function as a
gr inde r, san der, wir e bru sh, pol ishe r,
carving or c ut-off tool. Read all safety
warnings, instructions, illustrations and
specifications provided with this power
tool. Failure to follow all instructions listed
below may result in electric shock, fire and/or
serious injury.
Do not use accessor ies which are not
specifically designed and recommended by
the tool manufacturer. Just because the
accessory can be attached to your power tool,
it does not assure safe operation.
The RATED SPEED o f the accessori es
must be at least equal to the operating
speed setting marked on the power tool.
Accessories running faster than their RATED
SPEED can break and fly apart.
The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately controlled.
The arbor size of wheels, sanding drums or
any other accessory must properly fit the
sp i ndle or c ollet of the power tool.
Accessories that do not match the mounting
hardware of the power tool will run out of
balance, vibrate excessively and may cause
loss of control.
Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck. If the
mandre l is in sufficie ntly held and/or th e
overhang of the wheel is too long, the mounted
wheel may become loose and be ejected at
high velocity.
Do not use a damaged accessory. Before
each use inspect the accessory such as
abra sive wheels for chips and c racks,
sanding drum for cracks, tear or excess
wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped,
inspect for damage or install an undamaged
accessory. After inspecting and installing
an acce ssor y, p ositi on yours elf and
bystanders away from the plane of the
rotating accessory and run the power tool
at maximum no-load speed for one minute.
Damaged accessories will normally break apart
during this test time.
Wear pe rson al pro tecti ve equ ipme nt.
Depending on application, use face shield,
sa fety gogg l es or safet y gla sses. As
ap prop riat e, wear du st mask , h eari ng
protectors, gloves and workshop apron
capa ble of stoppi ng sm all abra sive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations. The dust
mask or respirator must be capable of filtrating
partic les gener ated by your oper atio n.
Prolonged exposure to high intensity noise may
cause hearing loss.
Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragme nts of workpiece or of a broken
accessory may fly away and cause injury
beyond immediate area of operation.
Hold p ower tool by insulated gr ipping
su rfac es o nly, wh en p erfo rmin g an
operation where the cutting accessory may
contact hidden wiring. Cutting accessory
contacting a “live” wire may make exposed
metal parts of the power tool “live” and could
give the operator an electric shock.
Always hold the tool firmly in your hand(s)
during the start-up. The reaction torque of the
motor, as it accelerates to full speed, can cause
the tool to twist.
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. Clamping a small workpiece
allows you to use your hand(s) to control the
tool. Round material such as dowel rods, pipes
or tubing have a tendency to roll while being
cut, and may cause the bit to bind or jump
toward you.
Position the cord clear of the spinning
accessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning accessory.
Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the surface
and pull the power tool out of your control.
After changing the bits or making any
adjustments, make sure the collet nut,
chuck or any other adjustment devices are
securely tightened. Loose adjustment devices
can unexpectedly shift, causing loss of control,
loose rotating components will be violently
thrown.

Safety Rules for Rotary Tools - (cont.)
Do not run the power tool while carrying it
at your side. Accidental contact with the
spinning accessory could snag your clothing,
pulling the accessory into your body.
Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the
housin g and excessiv e accumul atio n of
powdered metal may cause electrical hazards.
Do n ot o pera te the power tool n ear
flammable materials. Sparks could ignite
these materials.
Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Use only in well-ventilated area. Working in a
safe environment reduces risk of injury.
Allo w for suff icient space, at least 6”,
between your hand and the spinning bit. Do
not reach in the area of the spinning bit. The
proximity of the spinning bit to your hand may
not always be obvious.
Do not touch the bit or collet after use. After
use the bit and collet are too hot to be touched
by bare hands.
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 injury may result.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of the
accessory’s rotation.
For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can
dig into the surface of the material causing the
wheel to climb out or kickout. The wheel may
either jump toward or away from the operator,
depend ing on direc tion of the w heel ’s
movement at the point of pinching. Abrasive
wheels may also break under these conditions.
Kickback is the result of power tool misuse
and/ or incorrect operating procedures or
conditions and can be avoided by taking proper
precautions as given below.
Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can
control kickback forces, if proper precautions
are taken.
Use special care when working corners,
sh arp edg es etc. Avoi d b ounci ng and
snagging the accessory. Corners, sharp
edges or bouncing have a tendency to snag the
rotating accessory and cause loss of control or
kickback.
Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
Always feed the bit into the material in the
same direction as the cutting edge is exiting
fr om th e mat eria l (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.
When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide
cutters, always have the work securely
clamped. These wheels will grab if they
become slightly canted in the groove, and can
kickback. When a cut-off wheel grabs, the
wheel itself usually breaks. When a rotary file,
high-speed cutter or tungsten carbide cutter
grabs, it may jump from the groove and you
could lose control of the tool.
Safety warnings specific for grinding
and abrasive cutting-off operations:
Us e on ly wheel typ es that are
recommended for your power tool and only
fo r rec omme nded appli cati ons. For
example: do not grind with the side of a cutoff wheel. Abrasive cut-off wheels are intended
for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an
unrelie ved shoulder flange that ar e of
correct size and length. Proper mandrels will
reduce the possibility of breakage.
Do not ′′jam′′ a c ut-off wheel or apply
excessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility
to twisting or snagging of the wheel in the cut
and the po ssib ility of kickba ck or wheel
breakage.
Do not position your hand in line with and
behind the rotating wheel. When the wheel,
at the point of operation, is moving away from
1600A012FX.qxp_8220 1/30/17 12:41 PM Page 5

Additional Safety Warnings
your hand, the possible kickback may propel
the spinning wheel and the power tool directly
at you.
When wheel is pinched, snagged or when
interrupting a cut for any reason, switch off
the power tool and hold the power tool
motion less until the w heel comes to a
complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is
in motion otherwise kickback may occur.
Investigate and take cor rective acti on to
eliminate the cause of wheel pinching or
snagging.
Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed
under the workpiece near the line of cut and
near the edge of the workpiece on both sides of
the wheel.
Use extra caution when making a ′′pocket
cut′′ into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.
Safety warnings specific for wire
brushing operations:
Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying
excessive load to the brush. The wire bristles
can easily penetrate light clothing and/or skin.
Allow brushes to run at operating speed for
at least one minute before using them.
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.
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 use of these brushes and
may become imbedded in your skin.
Safety Rules for Rotary Tools - (cont.)
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.
Develop a periodic maintenance schedule
for your t ool. When cleani ng a tool be
careful not to disassemble any portion of
th e tool sin ce inter nal wire s may be
misplaced or pinched or safety guard return
sp ring s may be improp erly mount ed.
Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may
damage plastic parts.
Ensure the switch is in the off position
before inserting battery pack. Inserting the
battery pack into power tools that have the
switch on invites accidents.
Some dust creat ed by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
ca use ca n cer, b irth defects or ot h er
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.
Your ris k from these exp o s ures vari e s ,
depending on how often you do this type of
work. To r educ e your exposure to thes e
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.

COLLET NUT — To loosen, first press shaft
lock button and rotate the shaft by hand until
the lock engages the shaft preventing further
rotation. Your Dremel 8220 is equipped with a
quick collet lock mechanism. This mechanism
en gages the outpu t shaft in 8 sep a rate
locations on the shaft for easier operation.
Do not engage lock while
the Rotary Tool is running.
With the shaft lock engaged use the collet
wrench to loosen the collet nut if necessary.
The collet nut must be loosely threaded on
wh en in sertin g an acce ssory. Chan g e
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.
EZ TWIST™ INTEGRATED
WRENCH/NOSE CAP
The nose cap of your tool has an integrated
wrench allowing you to loosen and tighten the
collet nut without the use of the standard collet
wrench. Unscrew the nose cap from the tool,
line-up steel insert on inside of cap with collet
nut. With the shaft lock engaged twist nose cap
clockwise to tighten, and counter-clockwise to
loosen.
Assembly
Disconnect battery pack from tool before making any assembly,
adjustments or changing accessories. Such preventive safety measures
reduce the risk of starting the tool accidentally.

Operating Instructions
FIXING STUCK COLLETS – It is possible for a
c
ollet to get stuck within the collet nut especially if
a collet nut is tightened onto the tool without a bit
in place. If this happens, the collet can be
removed from the collet nut by pushing the shank
of an accessory into the hole in the collet nut.
This should cause the collet to pop out of the
collet nut.
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
a
ccessory or collet a 1/4 turn. Re tighten 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
fa shion un til best bala nce is a chiev ed. 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.
The hanger is provided for the use of hanging
your tool while using 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.

cordless rotary tool available today. It has a wide
speed range including a high performance motor
that allows the tool to maintain its speed under
load. The design of the tool also contains plenty
of soft grip so the tool can be held comfortably in
many positions. The quick collet lock mechanism
ma k e s lo c k ing th e out p u t sha f t easi e r for

many applications that the Dremel 8220 can
easily tackle.
Rotary Tool Introduction
The Rotary Tool has a small, powerful electric
motor, is comfort able in the hand, and is made to
accept a large variety of accessories including
ab r a sive whe e l s , drill bi ts, wire br ushes,
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 be come 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
30,000 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 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 als o 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
you. To learn about more uses and the versatility
of Dremel accessories 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.

To select the right speed for each job, use a
practice piece of material.
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 Multi-Saw
and Dremel Planer.
ELECTRONIC MONITORING
Your tool is equipped with an internal electronic
monitoring system that provides a “soft start”,
which will reduce the stresses that occur from
a high torque start. The system also helps to
maximize motor and battery performance by
by limiting the current to the tool when overload
and stall conditions occur. The motor and
battery pack are protected by limiting the
current to the motor in these situations.
VARIABLE SPEED ADJUSTER
Your tool is equipped with a variable speed
adjuster. The speed may be adjusted during
operation by sliding the adjuster back or forth
between any one of the settings.
You can refer to the charts on pages 27 – 30
to determine the proper speed, based on the
materi a l bei n g worked and the type of
accessory being used. These charts enable
you to select both the correct acces sory and
the optimum speed at a glance.
Operating Speeds
When eve r you hold the
t
oo l, be car e ful not to
cover th e air vents with your hand. This
blocks the air flow and causes the motor to
overheat.
For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger (Figure A).
The “Golf Grip” method of holding the tool can
b
e used for more aggressive operations such
as grinding a flat surface or using cutoff
wheels (Figure B).
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
ge t the most e ffi c i e nt work o u t of the
accessory.

Needs for Slower Speeds
Certain materials, however, (some plastics and
pr eciou s me tals, for ex ample) req uire 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.
T
o aid you in determ ining the opti m um
operational speed for differ ent materials and
different accessories, we have construct ed a
series of tables that appear on pages 27 – 30.
By referring to these tables, you can discover
the recommended speeds for each type of
ac cessor y. Look th ese tabl es over an d
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 the brush from bristles flying
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
do ne. Use par affin or other sui t able
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. Per haps y ou sh o uld b e usin g a
di ffer e nt access o ry, and perha p s a n
adjustment in speed would solve the problem.
Leaning on the tool does not help.
Let speed do the work!

INSERTING AND RELEASING
BATTERY PACK
Release battery pack from tool by pressing on
both sides of the battery release tabs and pull
away from housing.
To insert battery, align ba ttery and slide
battery pack into tool until it locks into position.
Do not force.
FUEL GAUGE
T
his tool is equipped with a fuel gauge that
tells you how much charge your battery has.
A fully charged battery is indicated when all
three LED lights ar e il lumi nated. As th e
battery discharges, the lights will turn off one
by one until only one light is on. When the
last light starts "f lash ing" , the b atte ry i s
almost empty. When the battery is dead, the
tool will automatically turn off. This will be a
sudden st o p as oppos e d to a gr a d u a l
winding down of the tool. Simply recharge
the battery and reuse.
3 lights - 100% charge remaining
2 lights – 50% charge remaining
1 light - 25% charge remaining
1
"flashing" light - tool is about to shut off
3 “side to side” lights – battery charge is too
low to run tool. Recharge the battery.
3 “flashing” lights – battery is too hot or too
cold for use. Turn tool off and let battery
return to normal operating temperature before
resuming use.
CHARGER INDICATORS, SYMBOLS
AND MEANING
If the indicator lights are “OFF”, the charger
is not receiving power from power supply
outlet.
If the green indicator light is
“BLINKING”, the battery pack is
being fast-ch a r g e d . F astcharging will automatically stop when the
battery pack is fully charged.
Fast-charging means that the battery will be
fully charged in one hour.
If the green indicator light is
"ON", t h e c h a r g e r is
plugged in but the battery
pack is not inserted, or the battery pack is
fully charged, or the battery pack is too hot or
co l d for f a st-charg i n g . The char g e r will
automatically switch to fast-charging once a
suitable temperature is reached.
IMPORTANT CHARGING NOTES
1. The charger was designed to fast charge
the battery only when the battery temperature
is between 32˚F (0˚C) and 113˚F (45˚C). If the
battery pack is too hot or too cold, the charger
will not fast charge the battery. (This may
happen if the battery pack is hot from heavy
use). When the battery temperature returns to
between 32˚F (0˚C) and 113˚F (45˚C), the
charger will automatically begin charging.
2. A substantial drop in operating time per
charge may mean that the battery pack is
nearing the end of its life and should be replaced.
3. Remember to unplug charger during storage
period.
4. If battery does not charge properly:
a. Check for voltage at outlet by plugging in
some other electrical device.
b. Check to see if outlet is connected to a
light switch which turns power “off” when lights
are turned off.

876 1-HOUR CHARGER
Plug charger cord into your standard power
outlet, then insert battery pack into charger.
The charger’s green indicator light will begin to
“BLINK”. This indicates that the battery is
receiving a fast charge. Fast-charging will
automatically stop when the battery pack is
fully charged.
When the indicator light stops “BLINKING”
(and becomes a steady g ree n light) fast
charging is complete.
The battery pack may be used even though
the light may still be blinking. The light may
require more time to stop blinking depending
on temperature.
The purpose of the green light is to indicate
that the battery pack is fast-charging. It does
not indicate the exact point of full charge.
The light will stop blinking in less time if the
battery pack was not completely discharged.
When charging several batteries in sequence,
the charge time may slightly increase.
Wh en t he ba ttery pac k is fully c harge d,
unplug the charger (unless you're charging
another battery pack) and slip the battery

Engraving Cutters
This group has a wide variety of sizes and
shapes, and are made for intricate work on
ceramics (greenwar e ) , wo o d ca r v i n g s ,
jewelry and scrimshaw. They often are used
in making complicat ed printed circuit boards.
They should not be used on steel and other
very hard materials but are excellent o n
wood, plastic and soft metals. 1/8" shank.
Structured Tooth
Tungsten Carbide Cutters
Fast cutting, needle-sharp teeth for greater
material removal with minimum loading. Use
on fibe r glass, wood, plas t ic, e p oxy a n d
rubber. 1/8" shank.
Aluminum Oxide Grinding Stones
(red/brown)
Round, pointed, flat — you name the shape
and there is one available in this category.
These are made of aluminum oxide and
cover virtually every possible kind of grinding
application. Use them for sharpening lawn
mo wer blade s, screwdr iver tips, knive s,
scissors, chisels and other cutting tools. Use
to remove f l a s h fr o m me t a l cast i n g s ,
deburring any metal after cutting, smoothing
welded joints, grinding off rivets and re mov ing
rust. These grinding stones can be resharped
with a dressing stone. In machine shops, high
speed drills and cut ters normally are ground
with aluminum oxide wheels. 1/8" shank.
Silicon Carbide Grinding Stones
(blue/green)
Tougher than aluminum oxide points, these
are m a d e es pe c ia lly fo r use on h ar d
materials s u c h as gl a ss and ce r a m i c s .
Typical uses might be the removal of stilt
marks and excess glaze on ceramics and
engraving on glass. 1/8" shank.
Diamond Wheel Points
Excellent for fine detail work on wood, jade,
ceramic, glass and other hard material. Bits
are covered with diamond particles. 1/8"
shanks. (Not recommended for drilling)
Wire Brushes
Three different shapes of wire brushes are
available. For best results wire brushes
should be used at speeds not greater than
15,000 RPM. Refer to Operating Speeds
section for proper tool speed setting. The
three s h a p es co m e in th r e e di f f e r e n t
materials: stainless steel, brass and carbon
wire. The stainless steel perform well on
pewter, aluminum, stainless steel, and other
metals, without leaving "after-rust". Brass
brushes are non sparking, and softer than
stee l; making them good for use on soft
me t a l like g o l d , cooper and b r ass. The
carbon wire brushes are good for general
purpose cleaning.

Bristle Brushes
These are ex c e l l e n t cleaning tool s on
silverware, jew elry and antiques. The three
shapes make it possible to get into tight
corners and other difficult places. Bristle
brushes c a n be us e d wi t h po l i s h i n g
compound for faster cleaning or polishing.
Brushing Pressure
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come
in contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of
the brush will be shortened due to wire
fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible
is in full contact with the work. Applying the
side or edge of the brush to the work will
resu lt in wire breakage and shortened
brush life.
Polishing Accessories
These in clude an impre gnated polishing
point and an impregnated polishing wheel for
bringing metal sur faces to smooth finish; a

Mandrel N° 402 has a small screw at its tip,
and is used with emery cutting wheels and
sanding discs. Higher speeds , usually
maximum, are best for most work, including
cutting steel. Which is shown here.
Mandrel No. 401 is used with the felt
polishing tip and wheels. Thread the tip on to
the screw carefully. The felt tip must thread
down straight on the screw Mandrel, and be
turned all the way to the collar.
To replace a band on the Drum Sander, loosen
the screw without removing it to contract the
drum then slide the old band off. Slide the new
sanding band on and then expand the drum by
tightening the screw once again.
Before each use, check
to make certain that all
components are assembled to accessory
shank and that the drum is sufficiently
expanded to secure the band during use. If
sanding band is loose on the drum during
operation it may “fly” off and strike you or
bystanders.
