SAFETY WARNINGS SPECIFIC TO
GRINDING AND ABRASIVE CUTTING-OFF
OPERATIONS
a. Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded
and are unsafe.
b. Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
c. Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
d. Do not use worn-down wheels from larger power
tools. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may
burst.
ADDITIONAL SAFETY WARNINGS
SPECIFIC TO ABRASIVE CUTTING
OFFOPERATIONS
a. Do not "jam" the 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 binding of the
wheel in the cut and the possibility of kickback or wheel
breakage.
b. Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
c. When wheel is binding 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 binding.
d. 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.
e. 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.
f. 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 TO
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. If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard.
Wire wheel or
brush may expand in diameter due to work load and
centrifugal forces.
c. Do not exceed 15,000 RPM when using wire
brushes.
ENVIRONMENT
DISPOSAL
The machine, accessories and packaging should be sorted
for environmental-friendly recycling.
ONLY FOR EC COUNTRIES
Do not dispose of power tools with household
waste!
According the European Guideline 2012/19/EC
for Waste Electrical and Electronic Equipment
and its implementation into national law, power tools that
are nolonger usable must be collected separately and
disposed of in an environmentally-correct manner.

ASSEMBLY
ALWAYS UNPLUG MULTITOOL BEFORE CHANGING
ACCESSORIES, CHANGING COLLETS, OR SERVICING
THE TOOL.
GENERAL
The Dremel multitool is a high quality precision tool that can
be used to perform detailed and intricate tasks. The wide
range of Dremel accessories and attachments allow you to
perform a large variety of tasks. These include tasks such as
sanding, carving, engraving, routing, cleaning and polishing.

k. 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.
l. 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.
m. 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.
n. Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
o. Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
p. Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing of
the disc or kickback.
q. Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment strings .
Loose and spinning attachment strings can entangle
your fingers or snag on the workpiece.
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 at the point of the binding. 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 kick out. 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. Always use auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start-up. The operator can
control torque reactions or kickback forces, if proper
precautions are taken.
b. Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c. Do not position your body in the area where the
power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel’s
movement at the point of snagging.
d. 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.
e. Do not attach a saw chain woodcarving blade
or toothed saw blade.
Such blades create frequent
kickback and loss of control.
