Safety, performance, and dependability have been given top
priority in the design of your rotary tool.
INTENDED USE
The rotary tool is intended to be used only by adults who have
read and understood the instructions and warnings in this
manual, and can be considered responsible for their actions.
With appropriate accessories fi tted, the product is designed
to perform grinding, sanding, sculpting, polishing, buffi ng,
etching and engraving.
The product is intended for consumer use only.
Do not use the product for any other purpose. Use of the
product for operations different from intended could result in
a hazardous situation.
WARNING! 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, fi re and/or serious injury.
Save all warnings and instructions for future reference.
ROTARY TOOL SAFETY WARNINGS
Safety warnings common for grinding, sanding, wire brushing,
polishing, carving or abrasive cutting-off operations
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.
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.
The rated speed of the grinding accessories must be at least
equal to the maximum speed marked on the power tool.
Grinding 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 arbour 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.
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.
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.
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.
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.
Hold power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. 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.
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 housing and excessive accumulation of
powdered metal may cause electrical hazards.
Do not operate the power tool near 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.
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.
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, 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.
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 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.
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.
