the wheel to the collet must be minimal. If the mandrel is
insuficiently held and/or the overhang of the wheel is too
long, the mounted wheel may become loose and 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 lying debris generated by
various operations. The dust mask or respirator must be
capable of iltrating 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 ly 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 irmly 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 both hands 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 of the power tool, 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 lammable
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, 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.
Maintain a irm 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 thin 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 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 the
steel saw, high-speed cutters or tungsten carbide cutter
grab, it may jump from the groove and you could lose
control of the tool.
Additional safety instructions for grinding
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.
For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved shoulder
lange that are of correct size and length. Proper mandrels
will reduce the possibility of breakage.
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.
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.
When wheel is binding or when interrupting a cut for
