1. Work area safety
a. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away
while operating a power tool.
Distractions can cause you to lose
control.
2. Electrical safety
a. Power tool plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified
plugs and matching outlets will reduce
risk of electric shock.
b. 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.
c. Do not expose power tools to rain or
wet conditions. Water entering a power
tool will increase the risk of electric
shock.
d. 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.
e. 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.
f. 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.
3. Personal safety
a. Stay alert, watch what you are doing and
use common 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.
b. Use personal protective equipment.
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

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.
c. Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and / or
battery pack, picking up or carrying the
tool. Carrying power tools with your
finger on the switch or energizing power
tools that have the switch on invites
accidents.
d. 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.
e. Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations.
f. 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.
g. 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.
4. Power tool use and care
a. 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.
b. Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the
switch is dangerous and must be
repaired.
c. 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.
d. 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.
e. 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. Many
accidents are caused by poorly
maintained power tools.
f. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
g. 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.
5. Battery tool use and care
a. Recharge only with the charger specified
by the manufacturer. A charger that is
suitable for one type of battery pack may
create a risk of fire when used with
another battery pack.
b. Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create a risk of
injury and fire.
c. When battery pack is not in use, keep it
away from other metal objects like
paper clips, coins, keys, nails, screws, or
other small metal objects that can make
a connection from one terminal to
another. Shorting the battery terminals
together may cause burns or a fire.
d. 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.
6. Service
a. Have your power tool serviced by a
qualified repair person using only
identical replacement parts. This will
ensure that the safety of the power tool is
maintained.
General Power Tool Safety Warnings
4
Safety warnings common for
grinding, sanding, wire
brushing, polishing, carving
or abrasive cutting-off
operations:
a. This power tool is intended to function
as a grinder, sander, wire brush,
polisher, carving or cut-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.
b. Do not use accessories 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.
c. The rated speed of the accessories 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.
d. 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.
e. The arbor size of wheels, sanding drums
or any other accessory must properly fit
the spindle or collet 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.
f. Mandrel mounted wheels, sanding
drums, cutters or other accessories
must be fully inserted into the collet or
chuck. If the mandrel is insufficiently held
and/or the overhang of the wheel is too
long, the mounted wheel may become
loose and be ejected at high velocity.
g. Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
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 accessory,
position yourself 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.
h. Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive 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 particles
generated by your operation. Prolonged
exposure to high intensity noise may
cause hearing loss.
i. Keep bystanders a safe distance away
from work area. Anyone entering the
work area must wear personal
protective equipment. Fragments of
workpiece or of a broken accessory may
fly away and cause injury beyond
immediate area of operation.
j. Hold power tool by insulated gripping
surfaces only, when performing 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 “liveand could give the operator an
electric shock.
k. 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.
l. 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.
m. 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.
n. 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.
o. After changing the bits or making any
adjustments, make sure the collet nut,
Safety Rules for Rotary Tools
5
Safety Rules for Rotary Tools
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.
p. 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.
q. Regularly clean the power tool’s air
vents. The motor’s fan will draw the dust
inside the housing and excessive
accumulation of powdered metal may
cause electrical hazards.
r. Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
s. Do not use accessories that require
liquid coolants. Using water or other
liquid coolants may result in electrocution
or shock.
t. Use only in well-ventilated area. Working
in a safe environment reduces risk of
injury.
u. Allow for sufficient 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.
v. Do not touch the bit or collet after use.
After use the bit and collet are too hot to
be touched by bare hands.
w. Do not alter or misuse tool. Any
alteration or modification is a misuse and
may result in serious personal injury.
x. 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, depending on
direction of the wheel’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.
a. 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.
b. Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp
edges or bouncing have a tendency to
snag the rotating accessory and cause
loss of control or kickback.
c. Do not attach a toothed saw blade. Such
blades create frequent kickback and loss
of control.
d. 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.
e. 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:
a. Use only wheel types that are
recommended for your power tool and
only for recommended applications. For
example: do not grind with the side of a
cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side
forces applied to these wheels may cause
them to shatter.
6
b. For threaded abrasive cones and plugs
use only undamaged wheel mandrels
with an unrelieved shoulder flange that
are of correct size and length. Proper
mandrels will reduce the possibility of
breakage.
c. Do not “jam” a cut-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
possibility of kickback or wheel breakage.
d. 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 your hand, the possible
kickback may propel the spinning wheel
and the power tool directly at you.
e. When wheel is pinched, snagged or
when interrupting a cut for any reason,
switch off the power tool and hold the
power tool motionless until the wheel
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 corrective action to
eliminate the cause of wheel pinching or
snagging.
f. 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.
g. 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.
h. 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:
a. 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.
b. 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.
c. 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
7
Additional Safety Warnings
a. GFCI and personal protection devices
like electrician’s rubber gloves and
footwear will further enhance your
personal safety.
b. Keep handles dry, clean and free from
oil and grease. Slippery hands cannot
safely control the power tool.
c. Develop a periodic maintenance
schedule for your tool. When cleaning
a tool be careful not to disassemble
any portion of the tool since internal
wires may be misplaced or pinched or
safety guard return springs may be
improperly mounted. Certain cleaning
agents such as gasoline, carbon
tetrachloride, ammonia, etc. may
damage plastic parts.
d. 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 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 and cement
and other masonry products, and
Arsenic and chromium from chemically-
treated lumber.
Your 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 those dust masks that are specially
designed to filter out microscopic particles.

further rotation. Your Dremel 8250 is
equipped with a quick collet lock
mechanism. This mechanism engages
the output shaft in 8 separate 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 15 to loosen the collet nut
1if 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
(Fig. 3). 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 3from
the tool, line-up steel insert on inside of
cap with collet nut 1. With the shaft lock
6engaged twist nose cap clockwise to
tighten, and counter-clockwise to loosen
(Fig. 4).
Collets
Four different size collets (Fig. 5), to
accommodate different shank sizes, are
avail able 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.

Intended Use
Assembly
Always use the collet
which matches the
shank size of the accessory you plan to
use. Never force a larger diameter shank
into a collet.
Note: Most rotary tool kits do not
include all four collets sizes.
Fixing Stuck Collets
It is possible for a collet 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 (Fig. 6). 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 accessory 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 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.
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.

Whenever you hold
the tool, be careful
not to cover the air vents with your
hand. This blocks the air flow and
causes the motor to overheat.
Slide "On/Off" Switch
The tool is switched "ON" by the slide
switch 7located 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.
Learn the Speeds
After the tool has been turned off:
- If you turn it back on within 5
minutes, the tool will turn on at its
last set speed setting.
- If turned on after 5 minutes, the tool
will turn on at its default speed
setting of 15,000 RPM.
Variable Speed Dial
Your tool is equipped with a variable
speed dial 8. The speed may be
adjusted during operation by rotating
the dial back or forth between any one
of the settings. One of the numbers on
the speed indicator 10 will light up
showing the current speed (Fig. 7).
You can refer to the charts on page 18
to determine the proper speed, based
on the materi al being 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.
Increasing the pressure on the tool is
not the answer when it is not
performing as you think it should.
Perhaps you should be using a different
accessory, and perhaps an adjustment
in speed would solve the problem.
Leaning on the tool does not help.
Let speed do the work!
All Dremel Rotary Tool attachments are
compatible with your tool, but you may
experience reduced run times on the
battery when using certain attachments.
Learn the LED Behavior
If you turn off the tool with the battery
still inserted, the tool LEDs will behave
as follows:
- The Speed LED will remain
illuminated for 5 minutes to show the
last set speed setting.
- The Warning and Battery Gauge LEDs
will remain illuminated for 30
seconds.
To turn off all LEDs, remove the
battery pack after the tool has been
turned off.

Red Warning LED
The red warning LED 9will illuminate
for one of the following reasons:
- Excessive tool temperature: turn the
tool off and remove the accessory
(Be careful the accessory may be
hot). Then turn the tool on and
allow it to run without load so the
motor’s fan can help cool down the
tool.
- Excessive battery temperature: turn
the tool off, remove the battery
pack and allow the battery to return
to normal operating temperature
before resuming use.
- Tool stall / overload warning: too
much pressure is being applied to
the tool. Reduce pressure to hold
and guide the tool. Allow the speed
of the tool to do the work.
Fuel Gauge
This tool is equipped with a fuel gauge
11 that tells you how much charge your
battery has. A fully charged battery is
indicated when all three LED lights are
illuminated. As the battery discharges,
the lights will turn off one by one until
only one light is on. When the last light
starts "flashing", the battery is almost
empty. When the battery is dead, the
tool will automatically turn off. This will
be a sudden stop as opposed to a
gradual winding down of the tool.
Simply recharge the battery and reuse.
Charging Battery Pack
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
“offwhen lights are turned off.
c. Check battery pack terminals for
dirt. Clean with cotton swab and
alcohol if necessary.
d. If you still do not get proper
charging, take or send tool, battery
pack and charger to your local
Dremel Service Center.
Note: Use of chargers or battery packs
not recommended by Dremel in the
battery/charger list will void the
warranty.
DREMEL CHARGER GAL12V-20
Plug charger cord into your standard
power outlet, then insert battery pack
12 into charger (Fig. 8).
If the indicator lights are “OFF”, the
charger is not receiving power from
power supply outlet.
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
green 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 blinking 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
3 lights – 70–100% charge remaining
2 lights – 40–70% charge remaining
1 light – 20–40% charge remaining
1 "flashing" light – Below 20% charge
remaining. Be prepared for tool to
shut off.

Service
NO USER SERVICE -
ABLE PARTS INSIDE.
Preventive maintenance performed by
un au thorized personnel may result in
misplacing of internal wires and
components which could cause serious
hazard. We recom mend that all tool
service be performed by a Dremel
Service Center. SERVICE MEN:
Disconnect tool and/or charger from
power source before servicing.
Batteries
Be alert for battery packs that are
nearing their end of life. If you notice
decreased tool performance or
significantly shorter running time
between charges then it is time to
replace the battery pack. Failure to do
so can cause the tool to operate
improperly or damage the charger.
D.C. Motors
The motor in your tool has been
engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend
it be examined every six months. Only a
genuine Dremel replacement motor
specially designed for your tool should
be used.
Cleaning
Certain cleaning
agents and solvents
damage plastic parts. Some of these
are: gasoline, car bon tetrachloride,
chlorinated cleaning solvents, ammonia
and household detergents that contain
ammonia.
Ventilation openings and switch levers
must be kept clean and free of foreign
matter. Do not attempt to clean by
inserting pointed objects through
opening
stop blinking in less time if the battery
pack was not completely discharged.
If the green indicator light is "ON", the
charger 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 cold for fast-charging. The
charger will automatically switch to fast-
charging once a suitable temperature is
reached.
When charging several batteries in
sequence, the charge time may slightly
increase.
When the battery pack is fully charged,
unplug the charger (unless you're
charging another battery pack) and slip
the battery pack back into the tool.
Maintenance
To avoid accidents, always disconnect the tool and/or charger from the
power supply before servicing or cleaning.
