side forces applied to these wheels may cause them to
shatter.
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.
d. Do not exceed 15,000 RPM when using wire brushes.

DREMEL CHUCK
Dremel Chuck allows you to quickly and easily change
accessories on Dremel Rotary Tools without changing collets.
Accepts accessories with 1/32” - 1/8” shank. To loosen, first
press shaft lock button and rotate the shaft by hand until the
lock engages the shaft preventing further rotation.
!
WARNING
DO NOT ENGAGE LOCK WHILE THE
ROTARY TOOL IS RUNNING.
With the shaft lock engaged use the wrench to loosen the
chuck and open the jaws.
Remove the accessory from the
chuck. If necessary, continue loosening the chuck so that the
new accessory fits between the jaws. Insert the new accessory
into the chuck far enough so that there is approximately 1/4”
between the end of the chuck and the beginning of the working
part of the accessory (drill bit flutes, sand paper, engraving end,
etc.).
With the shaft lock engaged, tighten the chuck using the
wrench to secure the accessory.
HELPFUL TIPS WHEN USING THE DREMEL CHUCK
• The Dremel Chuck and the collet and collet nut system are
interchangeable on this tool.
While the chuck will provide
you with the best experience for changing accessories, the
collet and collet nut will provide a more precise accessory
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, 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.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, sanding band, 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 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.
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,
